Column type DC charging piles are widely used in logistics parks, bus stations, fleet warehouses, public charging stations, and other scenarios due to their independent column structure, high-power fast charging, and strong outdoor adaptability. Different from wall mounted charging piles, column type devices do not need to be attached to walls and have higher adaptability to the site, but the installation and construction standards and operating procedures are more stringent. Many station operators tend to overlook key aspects such as surveying, foundation pouring, and grounding protection during project implementation, resulting in equipment failures and safety hazards in the later stages. This article provides a detailed explanation of the installation and proper use of column type DC charging piles from several aspects, including preliminary survey, on-site installation, debugging and acceptance, equipment operation, and operation and maintenance safety. 1、 Pre installation survey and scheme confirmation Before formal construction, on-site survey is a prerequisite for ensuring the stable operation of the project and cannot be directly carried out on site. Firstly, confirm the power supply conditions. Column DC piles are mostly powered by three-phase 380V, and the transformer capacity needs to be calculated. The transformer should reserve at least 20% power margin, and the cable laying distance should be confirmed to shorten the cable length as much as possible and reduce line losses. In terms of site, column charging piles should be selected in areas with solid and flat ground, avoiding low-lying water accumulation, fire exits, and tree covered areas. Priority should be given to planning rainproof and sunshade spaces for outdoor installation. A 0.5-1-meter heat dissipation and maintenance space should be reserved around the pile body to ensure smooth air intake and exhaust of equipment, and no debris should be piled up in the surrounding area. Simultaneously confirm the parking layout to ensure that the charging gun cable can cover the vehicle charging port normally, and reserve space for vehicle passage when deploying multiple devices. In addition, after completing the procedures and confirming the materials, the construction personnel must hold a valid electrician qualification certificate, prepare national standard cables, galvanized anchor bolts, flame-retardant conduit, grounding materials, etc. The cable diameter should be determined according to the equipment power. Armored cables should be preferred for outdoor buried cables, and protective designs should be made. 2、 Foundation construction and pile installation and fixation Column type DC charging piles cannot be directly placed on the ground and must have a concrete base poured to prevent settlement and tilting. Excavate the foundation pit according to the equipment drawings, pour a high-strength concrete base, with the base about 20 centimeters above the ground to avoid water immersion on the ground. Anchor bolts and cable conduits are pre embedded inside the base, and equipment installation work can only be carried out after the concrete has completely solidified. Lift and place the column pile on the base, align it with the anchor bolt holes, calibrate the verticality with a level, evenly tighten the rust proof anchor bolts, and ensure that the pile is stable without shaking. The cable is inserted into the column through the pre embedded pipe, and a suitable length is reserved inside the column for easy maintenance and repair in the future. All cable joints should be insulated, and waterproof sealing rings should be installed at outdoor wiring locations to prevent rainwater from infiltrating and causing short circuit faults. The electrical wiring process must strictly follow the equipment manual, distinguishing between three-phase live wire, neutral wire, and protective ground wire. The ground wire must be reliably connected to the grounding grid with a grounding resistance of less than 4 Ω. Install matching circuit breakers, leakage protectors, and lightning protection modules in the supporting distribution cabinet. All metal shells and column supports should be grounded uniformly to eliminate the risk of leakage. After wiring is completed, recheck the fastening of all terminals to avoid virtual connection and heating problems. 3、 Power on commissioning and project acceptance After the wiring is completed, it is forbidden to directly close and energize. First, disconnect the higher-level switch, use instruments to detect the insulation of the circuit, check for potential short circuits and phase errors, and confirm that there are no errors before gradually powering on. After powering on, observe whether the charging station display screen and indicator light start normally, and check whether the device has any alarm or error messages. Next, complete the device function debugging, configure network communication parameters, interface with the backend management system, and test whether the scanning, card swiping start stop, insulation detection, and protection functions are normal. If conditions permit, conduct a complete charging test using a real vehicle, observe the entire process of charging handshake, voltage and current output, and stopping charging, and confirm that overcurrent, overvoltage, and overheating protection can be triggered normally. After all tests show no abnormalities, the equipment qualification certificate, construction drawings, and inspection records will be organized to complete the project acceptance. At the same time, basic operation training will be provided to the station management personnel, and the equipment manual will be retained for easy reference and maintenance in the future. 4、 Standard Operating Procedure for Column DC Charging Pile The vehicle enters the charging parking space, shifts into P gear, tightens the handbrake, turns off the vehicle's power supply, and opens the vehicle's DC charging port cover. Visually inspect the charging gun plug for water accumulation, stains, and damaged foreign objects. Remove the charging gun, align it with the vehicle's DC interface, and insert it smoothly. If you hear the locking sound of the buckle, confirm that the charging gun is connected properly. Identity authentication is completed through the pile touch screen, scanning code or swiping card, and the device automatically shakes hands with the vehicle BMS system for communication. After confirming the battery status, charging is started. During the charging process, real-time operation data such as charging power, charging capacity, battery temperature, etc. can be viewed on the screen or in the management background. When the charging is completed or needs to be stopped halfway, you must first click on the stop charging button on the screen or mini program, wait for the device to cut off the high-voltage output, unlock the charging gun, and then unplug the gun head. It is strictly prohibited to directly remove the gun during the charging process. Return the charging gun to its original position, hang it neatly on the charging pile bracket, straighten out the cables, and avoid cable crushing and wear. 5、 Daily use and safety operation and maintenance precautions During daily use, it is forbidden to knock or pry the charging pile body, and do not rinse the charging pile shell directly with water. When plugging or unplugging a charging gun in rainy or snowy weather, be careful not to let water enter the gun head, and do not start charging if the interface is damp. The operation and maintenance personnel regularly check whether the anchor bolts are loose, whether the cable sheath is damaged, and whether the grounding connection is intact. Once the device triggers a fault alarm, immediately stop using it, cut off the power, contact the manufacturer's after-sales service for maintenance, and non professionals should not open the charging pile shell without authorization. Regularly cleaning the dust at the cooling port of the equipment can ensure the cooling effect, effectively extend the service life of the column DC charging pile, and ensure the long-term safe and stable operation of the station.

With the widespread adoption of new energy heavy-duty trucks, electric dump trucks, and logistics distribution vehicles, specialized fleet warehouse charging stations have become the core supporting facilities for logistics enterprises to reduce costs and increase efficiency. Unlike household and commercial charging stations, the charging scenario in fleet warehouses has exclusive characteristics such as centralized vehicle parking, batch energy replenishment, high-frequency operation, frequent dust and oil pollution on the site, and day night off peak charging. Many fleets blindly follow the trend of purchasing high-power equipment or low-priced models, which can easily lead to problems such as power grid overload, low charging efficiency, high equipment failure rate, and incompatibility with fleet models. This article combines the experience of CAMC charging piles and shares the standardized selection plan for charging piles in fleet warehouses from five dimensions: power matching, model selection, environmental adaptation, intelligent operation and maintenance, and compliance and safety. 1、 Accurately match charging power based on fleet model size Power selection is the core of fleet charging pile selection, which directly determines the energy replenishment efficiency and grid load, eliminating the "small horse pulling big car" or power waste. The small fleet mainly consists of electric delivery vehicles and light new energy trucks. The battery capacity of each vehicle is relatively small, and the demand for energy replenishment is mild. It is suitable for 120kW-180kW multi gun DC charging piles, supports multi vehicle time-sharing charging, and meets the daily short distance turnover energy replenishment needs. It is also suitable for the staggered charging mode at night in warehouses. Medium to large logistics fleets and heavy truck transportation enterprises mainly use electric tractors and electric dump trucks, with large battery capacity and high endurance requirements. Therefore, it is necessary to choose high-power DC fast charging piles with a capacity of 320kW-480kW. This type of vehicle can meet the full day operating mileage with a single charge, and is suitable for the scenario of centralized batch energy replenishment after the fleet receives the vehicle. For large warehouses with a large number of vehicles and concentrated charging periods, flexible group charging equipment can be used to dynamically allocate power and avoid peak overload of the power grid caused by multiple vehicles charging at the same time, greatly improving equipment utilization. 2、 Distinguish the model structure and adapt to the layout of the warehouse site The fleet warehouse site is divided into three scenarios: indoor enclosed warehouse, outdoor yard, and simple rain shelter. Each scenario corresponds to a dedicated aircraft model, taking into account space utilization and equipment stability. The indoor warehouse space is compact and the vehicles are parked neatly. Wall mounted charging piles or small floor standing DC piles are preferred, which do not occupy the driving channel, are dust-proof and oil proof, and are suitable for long-term stable indoor charging. Outdoor storage yards and parking areas have high levels of dust, large temperature differences between day and night, and frequent exposure to rainwater. Therefore, it is necessary to use IP55 high protection floor standing charging piles, which are sealed, corrosion-resistant, sun resistant, and rain and snow resistant, and are not afraid of complex warehouse conditions. For fleets with flexible venues and varying numbers of vehicles, CAMC flexible group charging all-in-one machines are the optimal choice. The modular design allows for on-demand expansion, and new vehicles added in the later stage do not require overall equipment replacement. It adapts to the scale of fleet iteration and upgrades, significantly reducing the cost of secondary renovation. 3、 Adapt to special working conditions in the warehouse, enhance durability and protection performance The fleet warehouse is different from ordinary charging sites in that it has long-term conditions such as dust, oil pollution, vehicle scratches, frequent start stop charging, etc. The durability of equipment is far more important than basic parameters. When making a purchase, it is important to pay close attention to the core configuration and prioritize the use of fully sealed waterproof modules that are dust-proof, moisture-proof, and resistant to oil erosion, in order to avoid module short circuits and downtime caused by harsh warehouse environments. At the same time, the equipment needs to have the ability to operate at a wide temperature range, and be able to operate stably at full power within the temperature range of -25 ℃ to 50 ℃, adapting to the seasonal temperature differences in warehouses across the north and south. The body is made of thickened sheet metal material, which is resistant to minor vehicle collisions. It is equipped with multiple heat dissipation systems, and can be charged in batches for a long time without high temperature or power reduction, ensuring stable energy replenishment for the fleet all day long. 4、 Intelligent operation and maintenance management, adapted to fine control of vehicle fleets The core demand for fleet charging is not only energy replenishment, but also unified control, energy consumption statistics, and cost accounting. Professional fleet warehouse charging stations must be equipped with an intelligent cloud management system that supports remote start stop, power regulation, automatic fault alarm, and charging data statistics. It can accurately record the charging amount, charging time, and energy consumption cost of each vehicle, facilitating fleet financial accounting and fleet management. At the same time, it supports automatic adaptation of peak and valley electricity prices, and can set up scheduled charging for valley electricity at night, maximizing the reduction of fleet electricity costs. The CAMC fleet dedicated charging station supports multi account permission management, remote equipment operation and maintenance, and one click troubleshooting, without the need for manual on-site monitoring, greatly reducing the labor cost of fleet operation and maintenance, and adapting to the needs of fine management of large-scale fleets. 5、 Verify compliance and security, avoid long-term operational risks Safety and compliance are the bottom line for the long-term operation of fleet charging stations. When purchasing, it is necessary to verify the complete qualifications of the equipment, have national standard certification, electrical safety testing reports, and be equipped with multiple protection functions such as overvoltage, undervoltage, overcurrent, short circuit, leakage, lightning protection, and emergency stop. The shell is made of flame-retardant material to eliminate electrical fire hazards and is suitable for warehouse personnel and vehicle intensive scenes. At the same time, it is necessary to match the capacity of the warehouse transformer with the equipment to avoid blindly installing high-power devices that may cause overloading and tripping of the power grid. Priority should be given to selecting brand original equipment, with a complete after-sales network, spare parts reserves, and technical support, to quickly respond to faults and reduce the loss of work caused by fleet downtime. Summary The core logic for selecting charging stations for fleet warehouses is to determine the power of the vehicle model, the type of vehicle on site, the protection based on working conditions, the intelligence based on operation, and the compliance based on landing. Light vehicle fleets are compatible with small and medium power multi gun charging stations, while heavy truck fleets use high-power fast charging and flexible group charging equipment; Indoor wall mounted models are preferred, while outdoor floor standing models with high protection are preferred. CAMC's dedicated charging stations for the entire fleet are optimized and upgraded for warehouse dust, oil pollution, and centralized charging conditions. They combine efficient energy replenishment, intelligent control, and safety stability to create a low-cost, high-efficiency one-stop new energy replenishment solution for logistics fleets.

Semi trailers are the core transportation equipment for highway trunk logistics, port transfer, and engineering transportation, relying on tractor traction to achieve efficient trailer transportation. There are a wide variety of semi-trailer categories in the market, with significant functional differences among models such as box type, warehouse rack, skeleton container, dump truck, flatbed, and refrigerated. Many logistics fleets only focus on price and load capacity when purchasing, ignoring the attributes of goods, operating conditions, and loading and unloading modes, resulting in issues such as mismatched vehicle models, compliance restrictions, and high operating costs. This article combines scenarios such as mainline freight transportation, cross-border ports, and engineering infrastructure to sort out the mainstream semi-trailer classifications, their respective advantages, and selection criteria, in order to help fleets make scientific choices. 1、 Differentiate mainstream semi-trailer categories based on the type of transported goods The first criterion for selection: The characteristics of the goods determine the basic model of the semi-trailer, and different types of goods have completely different requirements for the sealing, ventilation, and loading and unloading methods of the carriage. Box type semi-trailer: Fully enclosed box structure, rain proof, dust proof, anti-theft, suitable for the transportation of household appliances, express less than truckload, precision industrial products, and high-value goods. The trunk can choose a side curtain design, with open loading and unloading on the side, greatly improving the efficiency of small cargo loading and unloading, making it the main model for long-distance express delivery. The disadvantage is that it has a relatively large self weight and is not suitable for heavy cargo such as sand, gravel, and steel. Warehouse fence semi-trailer: With an open fence structure and outstanding ventilation performance, it is mainly used for the transportation of agricultural and sideline products, fresh produce, and light foam goods. The warehouse column is detachable and suitable for irregularly shaped goods, making it widely used in greenway transportation scenarios. Not suitable for valuable goods that are afraid of rain and easy to lose. Skeleton container semi-trailer: without a complete cargo box, equipped with container twist locks, specifically designed to carry standard 20ft/40ft containers, suitable for ports, customs yards, and multimodal transportation of public and iron water. Modular design is lightweight and easy to handle, making it a standard configuration for cross-border container logistics and unable to transport bulk cargo separately. Self dumping semi-trailer: equipped with a hydraulic lifting system, it is divided into two structures: side flip and rear flip. It relies on hydraulic power to automatically unload and is widely used for the transportation of engineering bulk materials such as sand and gravel, coal, slag, and ore. Infrastructure construction sites and mining areas have obvious advantages in short distance transportation, requiring regular maintenance of hydraulic pipelines and oil cylinders. Flat/low flatbed semi-trailer: With a flat open load-bearing surface, the low flatbed model has a lower cargo platform height and a stable center of gravity. It is suitable for transporting large and non disassemblable construction machinery such as excavators, transformers, and steel pipes, with flexible loading and unloading and minimal restrictions on the shape of the goods. Refrigerated semi-trailer: equipped with an independent refrigeration unit and insulation box to maintain a stable low-temperature environment, used for frozen food, pharmaceutical cold chain goods, with high temperature control accuracy requirements, and higher procurement and operation costs than ordinary vehicle models. 2、 Number of axles, frame and suspension configuration, matching load and road conditions After determining the vehicle model, it is necessary to choose the axle group and frame scheme based on the load capacity and road conditions, while also considering regulatory compliance. Three axle semi-trailer is the mainstream configuration for mainline transportation, compatible with the 55 ton total weight regulation for six axle trains, balancing load capacity and fuel economy; Engaged in special transportation of oversized items, multi axle low flatbed vehicles can be selected, but the over limit passage procedures need to be completed in advance. High strength alloy steel is preferred for the frame material, and lightweight design can reduce its own weight and increase effective cargo tonnage; Long term operation in mining areas and bumpy construction sites, it is recommended to thicken the longitudinal beams to enhance their impact resistance. The suspension system is divided into steel plate springs and air suspension. Air suspension has good shock absorption effect, protects precision goods, and is suitable for express delivery, cold chain, and instrument transportation; Steel plate springs have strong load-bearing capacity and are easy to maintain. They are suitable for transportation of sand, gravel, and heavy loads, and can adapt to harsh and bumpy road conditions. At the same time, it is necessary to match the compliant ABS braking system to ensure the safety of long-distance driving. 3、 Adaptation to operational scenarios, selecting the right vehicle models to improve turnover efficiency Long distance trunk logistics, less than truckload express delivery Priority box type side curtain semi-trailer and warehouse grille semi-trailer, supporting high-speed and long-distance stable driving, suitable for multi-point loading and unloading; The fleet implementing the trailer mode prioritizes the use of standardized skeleton container trailers, with flexible separation of the front and trailer to reduce waiting time for loading and unloading. Port and cross-border container business Directly using skeleton container semi-trailer, unified standards facilitate mechanized lifting at the port, adapt to customs yard automation operations, and is also a mainstream model for overseas cross-border logistics. Infrastructure construction, mining areas, and transportation of sand and gravel materials Choose rear/side dump semi-trailer for automatic unloading, saving labor; For working conditions with poor road conditions, strengthen suspension and wear-resistant frame configurations. Transportation of construction machinery and large equipment Choose a low flatbed semi-trailer, with a low cargo platform that facilitates the up and down movement of construction machinery, a lower center of gravity, and stronger driving stability. 4、 Compliance, lightweight and long-term operation and maintenance key points Choosing should not only compare the bare car price, but also evaluate long-term costs from multiple dimensions. Firstly, strictly verify the vehicle announcement to ensure that the overall dimensions, weight, and number of axles comply with national standards, and smoothly register and undergo annual inspections to avoid fines for exceeding the limit. Lightweight is an important consideration, reducing the weight of trailers while complying with regulations, directly increasing the effective cargo capacity, and improving the revenue of bicycles. At the same time, evaluate the universality of accessories, as mainstream car models have a large market share of parts and are easy to maintain; The maintenance cost of niche special trailers is higher in the later stage. If the fleet purchases CAMC series tractor heads, it is possible to confirm in advance the compatibility of the tractor pins, air circuits, and electrical interfaces to achieve seamless adaptation between the tractor head and trailer. For long-term operation, it is recommended to prioritize suppliers with well-established after-sales service outlets to ensure rapid supply of vulnerable parts and reduce downtime losses. Summary Core logic for selecting semi-trailer: cargo type determination, load road condition determination axle group suspension, operation mode confirmation loading and unloading plan. High value LTL container truck; Fresh greenway uses warehouse rack trailers; Choose skeleton trailers for port container transportation; Choose self dumping trailers for the transportation of engineering bulk materials; Low flatbed trailers are used for the transportation of large construction machinery. By combining regulatory standards, lightweight requirements, and comprehensive comparison of maintenance costs, the optimal combination of tractor and trailer can be achieved. CAMC can provide complete transportation solutions for domestic and foreign logistics customers, including tractor trucks and various types of semi trailers, suitable for diversified operational scenarios such as mainline logistics, port transfer, and engineering infrastructure.

Cold chain transportation requires extremely high temperature control stability and vehicle reliability. As the core transportation equipment of cold chain logistics, the selection of refrigerated trailers directly determines the cargo integrity rate and fleet operating costs. Many users only focus on price and cabin size when making purchases, neglecting refrigeration configuration, box insulation, and chassis compatibility. Long term operation is prone to problems such as leakage of cooling, overheating, deterioration of goods, and high fuel consumption. This article combines scenarios such as long-distance trunk lines, short distance urban transportation, and high-value goods transportation, and shares professional refrigerated trailer selection techniques from five dimensions: temperature control standards, refrigeration machine selection, container technology, chassis configuration, and compliant operation and maintenance, to help logistics fleets accurately select and efficiently reduce costs. 1、 Lock precise temperature control standards according to the transported goods The core prerequisite for choosing a refrigerated trailer is to match the corresponding temperature control scheme according to the transported goods. The refrigeration requirements of different categories of goods vary significantly, and mismatches can easily cause cargo damage. Fresh fruits, vegetables, fresh milk, flowers and other fresh-keeping products are suitable for temperatures ranging from 0 ℃ to 8 ℃, without the need for extreme low temperatures. They only require uniform temperature control, no wind drying loss, and are suitable for short distance urban delivery. Frozen meat, seafood, and frozen food require a stable -18 ℃ low temperature environment and must be equipped with a rapid cooling and constant temperature locking cryogenic configuration to prevent thawing and spoilage during transportation. For pharmaceutical reagents and precision cold chain products, it is necessary to support high-precision temperature control of ± 0.5 ℃, combined with a full temperature traceability system, to meet industry regulatory and inspection standards. For long-distance transportation vehicles across provinces, it is recommended to choose models with cold storage and power-off insulation functions to avoid temperature fluctuations caused by mid stop loading and unloading. 2、 Distinguish refrigeration units and adapt to different transportation conditions The refrigeration unit is the core component of a refrigerated trailer, mainly divided into two types: non independent and independent units. Choosing according to needs can avoid performance waste or insufficient power. Non independent units rely on tractor power for operation, with simple structure, convenient maintenance, and high cost-effectiveness. They are suitable for fixed routes, short distance distribution of urban supermarkets, and meet the needs of conventional preservation and frozen goods transportation. They are the first choice for small and medium-sized vehicle fleets. The independent refrigeration unit comes with a power system that does not rely on the front of the car. It can stably cool during driving, idling, and parking, with fast cooling speed and strong load resistance. Adapting to long-distance transportation across provincial trunk lines, high-value cold chain goods, and 24-hour uninterrupted operation of fleets, even if loading and unloading goods for a long time, the cold can be continuously locked, greatly reducing the risk of cargo damage. The only drawback is that the procurement and maintenance costs are relatively higher. 3、 Emphasize the craftsmanship of the box and control the core performance of the cold lock The insulation material and manufacturing process of the box directly determine the overall cooling efficiency and energy consumption performance of the vehicle, and are the key to distinguishing high-quality refrigerated trailers. High quality car models commonly use 80-100mm thick polyurethane sandwich insulation boards, which are evenly foamed without voids and have excellent thermal insulation performance. They can effectively reduce the loss of cooling capacity, lower the frequency of unit start stop, and reduce operating fuel consumption. In terms of process, vacuum adsorption integrated molding box is preferred, which has stronger sealing than splicing box and eliminates the hidden danger of edge and corner leakage. The doors, windows, and maintenance ports of the box are equipped with thick and anti-aging sealing strips, which can be tightly closed and adapt to complex working conditions such as high temperature, high humidity, and long-distance bumps. At the same time, the anti-corrosion and anti-aging inner and outer skins are optimized to avoid the sun and rain, greatly extend the service life of the box, and reduce the later maintenance costs. 4、 Match the number of chassis axles to balance load capacity and driving stability Cold chain is mostly used for heavy-duty transportation, and the chassis and axle configuration determine the vehicle's load-bearing capacity, stability, and compliance, directly affecting driving safety. Conventional greenway and general cold short distance transportation, priority given to three-axis refrigerated trailers, balancing load capacity, flexibility, and fuel economy, suitable for national conventional road conditions, with high pass rates and low operating costs. For large-scale heavy-duty refrigerated cargo and long-distance mainline transportation, it is recommended to choose a four axle vehicle with stronger load-bearing capacity and better vehicle stability. It is not easy to tilt at high speeds and is suitable for large tonnage cold chain transportation. At the same time, the focus is on inspecting the straight through beam, strengthening the suspension and braking system, selecting high-strength and lightweight materials, balancing heavy load performance and fuel saving effect, and adapting to long-term high-frequency heavy load operation. 5、 Verify intelligent compliance and ensure long-term stable operation Modern cold chain transportation emphasizes intelligence and compliance, and matching configurations cannot be ignored when purchasing. High quality refrigerated trailers come standard with real-time temperature control monitoring, remote traceability, and over temperature alarm functions, which can record the temperature and humidity data of the cabin throughout the entire process, provide timely warnings for abnormalities, and meet the requirements of cold chain supervision and compliance. At the same time, it is necessary to strictly verify the qualifications of the entire vehicle to ensure that its size, load capacity, and emissions comply with national standards, and that it can undergo normal license plate annual review and green pass procedures to avoid compliance risks. In terms of after-sales service, priority should be given to selecting models with wide network coverage and complete quality assurance. The core components have long-term quality assurance to reduce losses caused by malfunctions and shutdowns, ensuring the continuous operation of the fleet. Summary Choosing a refrigerated trailer should follow the core logic of "temperature control for goods, refrigeration for working conditions, insulation for the box, and chassis for road conditions". High cost-effective non independent unit models are preferred for short distance preservation transportation, while independent cryogenic units are suitable for long-distance high-value frozen goods transportation. The corresponding axle number chassis is matched according to the load requirements, and equipped with intelligent temperature control traceability configuration. Scientific selection can not only prevent cargo damage and reduce energy consumption, but also improve transportation efficiency, helping cold chain fleets achieve long-term profitable operation.

With the popularization of new energy vehicles, charging piles have become a standard facility in residential areas, parks, commercial stations, and logistics bases. The mainstream charging stations on the market are divided into two categories: wall mounted and floor standing. Many users are easily confused when purchasing, and blindly selecting leads to space waste, insufficient charging efficiency, high construction costs, and vulnerable outdoor equipment. The core differences between the two are concentrated in installation methods, power capabilities, protection levels, applicable scenarios, and operation and maintenance costs. This article combines the characteristics of CAMC's full range of charging pile products to provide a detailed breakdown of the differences and unique advantages between the two devices, helping private car owners, property management, and commercial operators to make accurate selections. A、 Difference between core structure and installation method The fundamental difference between wall mounted and floor standing charging stations lies in the installation carrier and space occupation form, which directly determine the equipment's adaptation scenario. Wall mounted charging station: relying on solid walls and columns for fixed installation, the body is lightweight and compact, without occupying ground parking space, and overall does not affect vehicle traffic and parking layout. Installation does not require civil construction, only simple wiring and fixation, short construction period, minimal site modification, only suitable for indoor scenes with reliable load-bearing walls, and cannot be independently placed outdoors. Floor standing charging pile: It adopts an integrated base vertical structure, which is independently installed on the ground without attaching any walls, and is fixed and placed on a concrete foundation. The equipment layout is flexible, allowing for free planning of parking spaces and locations. It is suitable for outdoor and open areas without walls, and has a stable structure that is resistant to wind and impact. It is the mainstream equipment for commercial public charging scenarios. B、 Difference in power and charging capacity The power configuration is the core watershed between the two models, directly determining the charging speed and compatible models. Wall mounted charging is mainly used for small and medium power AC charging, with mainstream power coverage of 7kW, 11kW, and 22kW, suitable for household passenger cars and small electric logistics vehicles, focusing on slow charging for energy replenishment. Suitable for long-term static charging scenarios at night, with low load pressure on the power grid, suitable for the conventional distribution capacity of residential areas and parks, and not recommended for high-frequency fast charging or heavy truck energy replenishment scenarios. Ground mounted support for high-power DC fast charging, CAMC ground pile covers the full power range of 60kW-240kW, compatible with air cooling and liquid cooling heat dissipation solutions, supports dual gun simultaneous fast charging, and can be adapted to 800V high-voltage platform passenger cars, new energy logistics heavy trucks, and engineering electric vehicles. The charging speed far exceeds that of wall mounted models, and the vehicle can be recharged in 15-40 minutes, perfectly matching the high-frequency turnover needs of public stations. C、 Difference between protective performance and environmental adaptation Different structural designs result in a significant difference in outdoor adaptability between the two devices, directly affecting their service life. Wall mounted charging stations are mostly IP54 basic protection level, focusing on indoor moisture and dust prevention, suitable for underground parking lots and enclosed park indoor parking spaces. Outdoor exposure to sunlight, direct rain, and salt spray corrosion environments can easily lead to line aging and water leakage faults. It is not recommended to install outdoors without protection. The floor standing charging pile comes standard with a high protection level of IP55 or above, with a sealed design that supports rain, dust, lightning, and sun protection. The CAMC outdoor version can be customized with upgraded configurations for salt spray and corrosion prevention, and is suitable for complex working conditions such as high-speed service areas, outdoor parking lots, port mining areas, coastal stations, etc. It can operate stably 24 hours a day.

Low cost and easy construction: No need for foundation construction, simple wiring, low installation cost, short cycle, old power grid does not require large-scale expansion, and the renovation cost is extremely low. 3. Low consumption and durability, simple operation and maintenance: stable power, simple structure, low failure rate, supports timed valley charging, suitable for long-term slow charging at home, with extremely low annual operation and maintenance costs. 4. Wide adaptability: Compatible with all household new energy vehicle models, it is the preferred cost-effective option for private parking spaces and internal charging for enterprises. E、 Unique advantages of floor standing charging stations 1. Flexible layout and strong scalability: No need to rely on walls, parking spaces can be freely planned, and equipment can be flexibly added or removed in the later stage, suitable for large-scale station and batch layout. 2. High efficiency and fast turnover of fast charging: High power DC fast charging is suitable for peak public traffic flow, greatly improving parking turnover and helping commercial stations increase revenue. 3. Outdoor all-weather adaptation: The sturdy vertical structure is resistant to impact, wind and rain, high and low temperatures, and the stability under complex and harsh working conditions far exceeds that of wall mounted models. 4. Complete intelligent commercial attributes: equipped with 4G networking, cloud billing, time-sharing price adjustment, remote operation and maintenance, adapted to external charging operation, centralized fleet management, supporting overseas OCPP protocol and multilingual customization. F、 Summary of Accurate Scene Selection Prioritize choosing CAMC wall mounted charging stations: private parking spaces, underground garages in residential areas, indoor parking lots for enterprises, and low-speed energy replenishment scenarios for park use, pursuing low cost, low energy consumption, and no land occupation. Priority should be given to CAMC floor standing charging stations: public commercial and outdoor venues such as highway service areas, commercial outdoor parking lots, logistics parks, bus stations, mining area heavy truck charging stations, etc., which require high-frequency fast charging, centralized operation, and all-weather operation. Conclusion Overall, wall mounted charging stations are mainly used for household, personal, low-cost, and space saving purposes, and are the preferred choice for static slow charging needs; Floor standing charging piles are mainly used for commercial, fast charging, high adaptability, and high turnover, and are the core equipment of public charging stations. CAMC relies on a comprehensive product matrix to provide one-on-one exclusive charging solutions based on user site conditions, electricity needs, and operating modes, balancing household convenience and commercial efficiency, and adapting to various charging scenarios at home and abroad.

Floor standing DC charging piles, also known as column integrated fast charging piles, are installed on independent vertical bases without the need to attach to walls. They are suitable for outdoor parking lots, logistics parks, high-speed service areas, bus stations, mining heavy truck bases, and other non wall fixed scenarios. Compared with wall mounted piles, ground mounted piles have a wider power coverage, stronger heat dissipation performance, and support for all-weather outdoor operation, making them the mainstream equipment for commercial centralized charging scenarios. CAMC floor standing charging stations cover 60kW-240kW full power air-cooled and liquid cooled models, catering to the energy replenishment needs of passenger cars and new energy heavy-duty trucks. This article explains standardized purchasing methods from five dimensions: applicable scenarios, power matching, protective cooling, intelligent operation, and cost after-sales. A、 Distinguish usage scenarios and determine the specifications of the landing pile foundation The core advantage of landing piles is that there are no wall restrictions on installation, and different site traffic and vehicle types directly determine the model selection. 1. Urban public passenger car stations Outdoor parking spaces in shopping malls, roadside charging stations in counties, and parking lots in scenic areas. The traffic is mainly composed of household new energy small cars, with a daily charging capacity of less than 20 units, and priority given to 120kW double gun wind cold ground piles. One machine with two guns can serve two vehicles simultaneously, occupying a moderate area, simple construction, and suitable for scattered charging points. 2. High speed hubs and large commercial charging stations Due to the concentration of long-distance traffic and the short dwell time of vehicles, the pursuit of fast energy replenishment, 180kW/240kW liquid cooled ground piles are selected. The liquid cooled cable is lightweight and provides continuous high-power output. The 800V high-voltage vehicle model can be charged quickly at full speed, greatly reducing the waiting time for car owners and improving station turnover efficiency. 3. Logistics parks, electric heavy-duty trucks, ports, mining areas, and stations Electric tractor and electric dump truck have large battery capacity and require continuous high-power replenishment. Priority should be given to 240kW high-power landing piles, equipped with extended charging guns, and suitable for the height of heavy engineering vehicle charging ports; Mining areas are prone to high levels of dust and require all-weather outdoor operations. The option is to enhance dust and anti-corrosion measures. 4. Bus and sanitation dedicated stations Vehicles are centrally charged at night, and 120kW wind cooled ground piles can be selected in batches for lower deployment costs. Combined with timed charging function, night valley electricity can be used to reduce overall electricity costs. B、 Matching power and voltage platforms to avoid performance waste Choosing a landing pile should not blindly pursue high power, but should be judged comprehensively based on the vehicle battery voltage and the capacity of the station transformer.   60kW landing pile: suitable for small locations in old industrial parks with limited transformer capacity, only meeting the basic energy replenishment needs of light logistics vehicles and low-speed commuting vehicles. It takes a long time to charge and is suitable for low flow supporting locations.   120kW dual gun landing station: a universal mainstay in the industry, compatible with mainstream 400V passenger cars, with automatic power sharing for both cars charging simultaneously, and peak value for a single gun 120kW， More than 90% of new energy vehicles can be adapted, with moderate investment in power distribution renovation and the strongest universality.   180/240kW liquid cold ground pile: supports a wide voltage range of 200V-1000V, perfectly matched with 800V high-voltage platform new cars and electric heavy-duty trucks, with continuous high power without attenuation; But higher requirements are placed on the capacity of transformers, and large-scale charging stations will be built and deployed in batches.   Reminder for avoiding pitfalls: When the old distribution capacity of the community is insufficient, purchasing a large number of 240kW high-power piles can easily cause power grid overload. Priority should be given to choosing 120kW medium power models. C、 Protection and cooling system determine outdoor service life Ground piles are placed outdoors all year round, and dust and water resistance, as well as heat dissipation ability, are key to long-term stable operation.   Protection level: Ordinary urban outdoor venues use IP55 standard models to meet the basic requirements of rain and dust prevention; Upgraded IP65 high protection equipment for coastal ports, mining areas, and dust prone construction sites, equipped with sealed wiring compartments and anti salt spray coatings to resist sea wind corrosion and sediment intrusion.   There are two types of cooling solutions: air-cooled and liquid cooled. Wind cooled ground piles have lower costs, are easy to maintain, and are suitable for public stations with moderate daily charging frequency; Liquid cooled heat dissipation and temperature control are more stable, and there is no high temperature power drop during long-term high-power charging. The cable is lightweight and easy to plug and unplug, suitable for high load continuous operation scenarios such as high-speed and heavy trucks. Base structure: CAMC ground pile thickened integrated carbon steel base, with stable load-bearing capacity, matched with expansion bolts for fixation. During the rainy season, the internal circuit is not easily soaked by accumulated water on the site, reducing the probability of short circuit faults. D、 Intelligent operation configuration, divided into self use and commercial on-demand selection Personal/Corporate Internal Use Stations Basic configuration is sufficient to meet the requirements: card swiping activation, timed valley electricity charging, remote monitoring through mobile app, battery level recording, no need for complex billing system, simple operation, and reduced equipment procurement costs. Commercial charging stations for external fees Must be equipped with a complete cloud operation system: supporting 4G/WiFi networking, QR code payment, time-sharing price adjustment, order backend statistics, remote fault warning, OTA online upgrade. Administrators can remotely view the operating status of each landing pile, automatically push fault reminders, and reduce manual inspection costs; Overseas export models can be customized with multilingual backend and OCPP international communication protocol.   Multiple safety protections are standard across the entire range: overvoltage, overcurrent, leakage, lightning protection, high-temperature shutdown, collision power-off. Outdoor models are equipped with low-temperature preheating modules, which can start normally in an environment of minus 30 ℃. E、 Comprehensive landing cost and after-sales support The complete cost of landing piles includes equipment, cables, civil foundation, power distribution renovation, and installation construction. The air-cooled 120kW model has the lowest comprehensive investment and is suitable for small and medium-sized stations; The initial purchase price of liquid cooled high-power models is relatively high, but fast charging brings higher traffic revenue and faster long-term cost recovery for large high-speed stations. On the installation level, the landing pile only needs to harden the concrete foundation, without the need for wall modification, suitable for open areas without walls, with a short construction period, and the pile position can be separately increased or decreased in the later stage, making expansion flexible. In terms of after-sales service, the CAMC floor standing charging pile comes with a 2-year warranty for the entire machine and a 5-year warranty for the core components of the power module.

Wall mounted AC charging stations have become the mainstream charging equipment for private parking spaces, underground garages in residential areas, internal parking lots in enterprises, and small fleets in parks due to their advantages of small size, non occupying wall installation, convenient construction, and high cost-effectiveness. There are significant differences in power, protection, and intelligent configuration of wall mounted piles on the market, and many users blindly purchase them, resulting in power mismatch, outdoor water leakage faults, inability to remotely control, slow charging, and other problems. CAMC charging stations cover the full range of wall mounted models including 7kW, 11kW, and 22kW, catering to both household and small commercial scenarios. This article outlines standardized purchasing solutions from five dimensions: power matching, installation environment, safety qualifications, intelligent functions, and landing costs. 1、 Match the appropriate power according to the power supply and vehicle model Power is the first criterion for selection, and the core follows the dual matching principle of "vehicle upper limit+meter capacity", without blindly pursuing high power. 7kW single-phase 220V wall mounted pile (mainstream for household use) Suitable for ordinary 220V residential electricity meters with a rated current of 32A, it can be used by the vast majority of household new energy passenger vehicles and light electric logistics vehicles. It can fully charge the vehicle's battery in 8-10 hours at night, with low load pressure on the community's power grid. Old communities do not require large-scale line renovation, making it the preferred model for private parking spaces. 11kW/22kW three-phase 380V wall mounted pile (enterprise/high-end household) Three phase industrial electricity is required for household use, with a charging efficiency improvement of 40% -100%, suitable for high-end passenger cars and small electric vehicles that support three-phase AC charging. Suitable for enterprise fixed fleet and factory supporting parking spaces, multiple wheels can be quickly replaced and recharged at the same time, but it is necessary to apply for meter expansion to the power department in advance, and the initial wiring cost is slightly higher. Avoiding pitfalls in purchasing: If the vehicle's on-board charger only supports a maximum of 7kW AC input, even if a 22kW high-power wall mounted charging station is installed, the charging speed will not increase, only increasing procurement and wiring costs. 2、 Select the protection level based on the installation site Wall mounted piles can be installed in two environments: indoor and underground garages, and outdoor environments. The protection level directly determines the service life of the equipment. Underground garage, enclosed indoor parking space, no direct rainwater shower, using IP54 basic protection model is sufficient to meet daily dust and moisture prevention needs; The IP55/IP65 high protection wall hanging piles must be selected for the outdoor walls, ground outdoor parking spaces, and coastal communities. The complete machine must be sealed with sheet metal and waterproof junction bins to resist rainstorm, sun exposure, and salt fog corrosion. The CAMC outdoor model has upgraded moisture-proof sealing rubber rings. It is not easy to short circuit and leak electricity after long-term outdoor use. Hainan Provincial Market Supervision and Administration Bureau. At the same time, check the wall conditions: only concrete and solid brick concrete load-bearing walls can be directly wall mounted, while lightweight partition walls and insulated walls need to be equipped with dedicated load-bearing brackets to avoid the risk of equipment detachment. 3、 Safety and qualifications: Hard standards cannot be compromised Charging safety is the core bottom line of wall mounted piles, and priority should be given to checking the three major hard qualifications and protective configurations when selecting. Firstly, the product must have mandatory 3C certification and comply with GB/T 18487 and GB 39752 national standards. Equipment without certification cannot pass property inspection and there is a risk of fire and leakage; Export overseas models can provide CE certification and are compatible with electricity standards from multiple countries. Secondly, it comes standard with ten layers of safety protection: overvoltage, overcurrent, leakage, lightning protection, overheating, short circuit, insulation monitoring, collision power-off, low-temperature protection, and flame-retardant shell. The CAMC wall mounted pile is equipped with a B-type leakage protector, which can simultaneously detect AC and DC leakage. If the charging is abnormal, the power supply will be automatically cut off within 0.1 seconds to prevent safety accidents. Thirdly, hardware material selection: The gun head adopts silver plated conductive terminals, and the cable is a low-temperature resistant pure copper flame-retardant cable. The optional 4-meter/7-meter extended gun cable is suitable for different parking angles. 4、 Optional intelligent management function on demand Distinguish between personal use and small commercial use, select intelligent modules as needed to avoid functional redundancy and budget increase. Private household basic model: supports card swiping start, timed valley electricity charging, remote start stop of mobile APP, charging power statistics, and can set automatic charging during low valley periods at night, greatly reducing electricity expenses and meeting daily commuting charging needs. Enterprise park and small fleet commercial funds: adding 4G networking, cloud backend cluster management, time-based billing, multi person card swiping permission grading, remote fault warning. Administrators can uniformly view all parking space charging orders and energy consumption data, adapting to internal employee vehicle management of enterprises, without the need for manual on-site monitoring. The entire series supports OTA online upgrades, and the control program can be updated for free in the future to continuously optimize the charging logic. 5、 Comprehensive landing cost and supporting services Purchasing should not only consider the bare price of the equipment, but also calculate the comprehensive cost of the entire set, including equipment, cables, air switches, construction and installation, and after-sales maintenance. The wiring of the 7kW single-phase wall mounted pile is simple, and a 6-square-meter copper core cable is sufficient. The installation cost is low, making it suitable for private car owners with limited budgets; The 11kW/22kW three-phase model requires cables of at least 10 square meters, and expanding the electricity meter will increase the cost of a small renovation, making it suitable for long-term high-frequency charging fleets. Priority should be given to brands that provide one-stop survey and installation services. CAMC can conduct on-site surveys of walls, lines, and meter capacity, and provide exclusive wiring plans to avoid the inability to install equipment after purchase. In terms of after-sales service, the entire series of wall mounted pile machines have a 2-year warranty, and the core power module has a 5-year warranty. The service network covers the whole country, and any faults can be repaired on-site without the need for self disassembly and repair. Summary Core logic for selecting CAMC wall mounted charging piles: Choose the 7kW single-phase IP54 model for household ordinary parking spaces; Enterprises, high-end car models, pursuing fast charging choose 11kW/22kW three-phase models; Upgraded IP65 high protection version for outdoor and coastal environments. Prioritize checking the vehicle charging limit and the capacity of the community's electricity meter, identify national standard safety certification, focus on timed power-saving functions for household use, and choose cloud cluster management configuration for commercial use. CAMC's full range of wall mounted pile structures are compact and flexible to install, catering to domestic household, enterprise park, and overseas small parking lot scenarios, providing safe and economical wall mounted charging solutions for various new energy vehicle owners. FAQ What power wall mounted charging piles are suitable for old residential areas? Old residential areas prioritize 7kW single-phase 220V wall mounted piles, with the lowest requirements for power distribution renovation. Most 40A/60A electricity meters can be directly adapted. Do outdoor parking space wall mounted piles need to be additionally equipped with rain proof boxes?

Can multiple wall mounted charging stations in an enterprise be centrally managed in the background? Sure, CAMC commercial wall mounted piles support 4G networking and are equipped with a cloud operation platform to achieve centralized billing, permission control, and remote fault reminders for multiple piles.

As the core equipment for rapid energy replenishment of new energy vehicles, DC charging piles, with their high-power DC direct charging characteristics, significantly shorten the waiting time for charging. They are widely used in high-speed service areas, urban commercial charging stations, logistics heavy truck yards, port mining areas, bus stations and other scenarios. The market DC piles are divided into two main structures: column integrated DC piles and cabinet type split charging piles, with a power coverage of 60kW-600kW, suitable for 400V and 800V full voltage platform passenger cars, electric logistics vehicles, electric traction vehicles, and electric dump trucks. Different structures, powers, and heat dissipation schemes have significant differences in on-site adaptation, distribution investment, operational efficiency, expansion capacity, and full cycle operation and maintenance costs. Blind selection can easily lead to transformer overload, wasted parking space, low equipment utilization, and high expansion and renovation costs in the later stage. The CAMC layout includes a complete DC fast charging product matrix, covering integrated single/double gun DC piles, modular split charging piles, and equipped with air cooling and liquid cooling heat dissipation solutions. The selection is comprehensively judged based on five dimensions: operational scenario traffic volume, vehicle type, site conditions, power grid distribution capacity, and long-term expansion planning. The selection logic is decomposed layer by layer from structural differentiation, power matching, core hardware configuration, scenario adaptation, and cost control. Firstly, distinguish the structural characteristics of the two mainstream DC piles. The column integrated DC pile integrates the rectifier power module, control system, heat dissipation duct, and charging gun into a single vertical body, with a complete power range of 60kW-240kW. The dual gun model supports power sharing, and the single pile is installed independently on the ground, requiring only a concrete foundation for the parking space and no separate distribution room. The wiring is simple, the construction period is short, single equipment failures do not interfere with each other, and the operation and maintenance threshold is low. It is suitable for operating entities with scattered parking spaces, small-scale stations, limited budgets, and no expansion plans; The cabinet type split charging stack consists of a centralized power cabinet and multiple lightweight charging terminals. The total power of a single cabinet is 160kW-600kW, and it can be matched with 2-8 charging terminals. It is equipped with an intelligent dynamic power distribution system, which automatically distributes power according to demand when multiple vehicles are charging at the same time. More charging guns can be arranged with the same transformer capacity. The power cabinet can be centrally placed in the distribution room and at the corner of the station. The small size of the parking terminal saves parking space. The modular design allows for individual replacement of damaged modules without affecting the overall operation of the machine. It is suitable for large logistics parks, mining heavy truck stations, and high-speed large-scale hub charging stations with a daily traffic flow of more than 50 units, 24-hour continuous operation, and continuous expansion in the later stage. The disadvantage is that the initial investment in civil engineering, cable and cabinet procurement is higher. Secondly, according to the vehicle type and station flow, the corresponding power level is matched. The 60kW DC pile is suitable for small parks, emergency fast charging in residential areas, short distance urban light truck fleets, mainstream 400V platform household passenger cars, and light logistics vehicles for energy replenishment. The charging time is 45-70 minutes for 20% -80%, and the distribution load is low. Old park transformers do not require large capacity increases, making it suitable for low flow points with an average daily charging of less than 10 units; The 120kW dual gun DC pile is a commonly used mainstream model, compatible with over 95% of passenger cars, ride hailing vehicles, and medium-sized logistics vehicles on the market. The peak power of a single gun is 120kW, and both vehicles can be charged simultaneously with an average of 60kW. Fast charging from 20% to 80% takes only 25-35 minutes. Shopping mall parking lots, county-level charging stations, and small bus stations are preferred to balance charging efficiency and distribution renovation costs; 180kW/240kW high-power integrated pile is suitable for high-speed service areas and high-end charging stations in commercial districts, supporting 800V high-voltage platform new energy vehicles. The liquid cooled gun model has a larger charging current and lightweight cables, and can replenish long-distance range in 15-20 minutes, meeting the short-term energy replenishment needs of long-distance car owners; The 360kW-600kW split charging stack is designed specifically for electric heavy-duty trucks, electric dump trucks, and port tractors. It has a battery capacity of 450kWh-600kWh and is exclusive to heavy-duty vehicles. Multiple terminals provide fast charging for heavy-duty trucks simultaneously, and dynamic power dispatch avoids peak overload of the power grid. It is the preferred choice for large-scale heavy-duty truck energy replenishment in mining areas and large logistics hubs. According to the configuration of heat dissipation and charging gun, the adaptation environment can be distinguished. Conventional air-cooled DC piles have moderate cost, simple maintenance, and can be used in urban indoor parking lots and shopping mall parking spaces with less dust; The liquid cooled cooling DC pile cable is thinner, lighter in weight, and can carry a larger current. It has a lower temperature rise during continuous high load charging, making it suitable for high-speed, mining areas, and 24-hour high-intensity operation scenarios. It can be customized as an upgraded anti-corrosion and dust-proof model for coastal high salt spray and multi dust plant areas; The ordinary national standard charging gun is suitable for small and medium power models ranging from 60kW to 180kW, while the liquid cooled lightweight gun is suitable for overcharging and megawatt level charging piles of 240kW and above, reducing the burden of insertion and removal for operators. The core parameters, safety, and intelligent configuration are the selection criteria, and the voltage range is given priority to the 200V-1000V wide voltage output model. It is compatible with new and old 400V/800V all platform vehicles to avoid new cars being unable to charge at full power; Equipment conversion efficiency ≥ 95%, silicon carbide module models have lower losses and long-term power savings; In terms of safety, all CAMC series DC piles come standard with multiple protections including overvoltage, overcurrent, leakage, lightning protection, high-temperature shutdown, and collision power-off. The outdoor model is IP55 dustproof and waterproof, and is equipped with a low-temperature preheating module for stable start-up at -30 ℃ in high-altitude areas; The communication protocol supports the national standard GB/T 27930 and the international OCPP 2.0.1, and is paired with a cloud based operation management platform to achieve QR code billing, order statistics, remote fault warning, and OTA online upgrades. Overseas stations can customize multilingual backends, multi country voltage standards, and CCS/GB/T dual charging interfaces. Select models based on the factory site and power distribution conditions, and prioritize integrated small DC piles or split type lightweight terminals for indoor underground garages, limited floor height, and narrow parking spaces to reduce equipment footprint; Open air large logistics park, sufficient mining area, self owned large capacity transformer, optional high-power split charging pile to achieve high-density gun distribution; The capacity of transformers in old industrial parks is insufficient. To avoid large quantities of high-power piles above 240kW, a 60kW/120kW integrated power distribution system is selected to reduce the cost of power distribution renovation; New planning large-scale charging stations will be built, with long-term expansion needs reserved. Split charging piles will be deployed in one step, and new charging terminals will be added in the later stage without the need to replace the main power cabinet, significantly reducing expansion costs. Standardized selection plan for different scenarios, including community facilities, office parking lots, and small urban vehicle fleets (up to 10 units per day): 60kW/120kW air-cooled integrated dual gun DC piles; Urban commercial districts, small and medium-sized service areas on highways, and ride hailing stations (10-30 units per day): 120kW/180kW integrated, high-end locations equipped with 240kW liquid cooled models; Large logistics parks, electric heavy-duty truck exclusive stations, port transfer bases, high-speed large-scale hubs (with an average of 50 or more units per day and 24-hour operation): 360kW-600kW modular split charging piles; High corrosion and harsh working conditions in mining areas and coastal areas: customized configuration of split charging piles and complete machine dust and salt spray prevention. SUMMARY Core logic for selecting CAMC DC charging piles: small-scale decentralized points, short-term self use, limited budget, choose integrated DC piles; Large high-density stations, centralized energy replenishment for heavy trucks, and priority given to split type charging piles with long-term expansion plans; The urban passenger car scenario is suitable for medium power of 60kW-180kW, and high-power liquid cooled models of 240kW or above are selected for long-distance, high-speed, and heavy engineering vehicles.

With the popularization of new energy heavy-duty trucks, electric dump trucks, logistics tractors, and buses, the demand for high-power DC fast charging equipment continues to grow in logistics parks, mining stations, high-speed service areas, and urban comprehensive charging stations. The mainstream market is divided into two categories: cabinet type split charging piles (charging piles+terminal guns) and column integrated charging piles. The two have significant differences in power expansion, site occupation, operation and maintenance difficulties, construction costs, and adaptation scenarios. Blind selection will lead to problems such as wasted on-site station space, low utilization of distribution capacity, difficulty in later expansion, and high operation and maintenance costs. The CAMC charging station has a complete layout of two product lines, covering a full power range of 60kW-400kW, suitable for all models of passenger cars and new energy commercial vehicles. The selection needs to be comprehensively judged based on five dimensions: site space, daily charging traffic flow, vehicle dwell time, long-term expansion planning, and budget. Firstly, the core structure and basic characteristics of two types of products are sorted out. The column integrated charging pile is designed as a whole machine integration, with the power module, heat dissipation system, control unit, and charging gun all integrated into a single vertical body, divided into single gun and double gun versions, with a power of 60kW-240kW. The whole machine can be installed independently on the ground with only a concrete foundation, without the need for a separate power distribution room. The wiring is simple and the construction period is short. The IP55 high protection body is suitable for outdoor parking lots, shopping mall ground parking spaces, and small fleet stations. The single equipment operates independently, and a single failure will not interfere with the remaining piles; The cabinet type split charging pile is composed of a high-power rectifier power cabinet and multiple column charging terminals. The power cabinet houses all rectifier modules in a centralized manner, and a single cabinet can integrate a total power of 160kW-600kW. It is equipped with 2-6 independent charging terminals and supports dynamic power distribution. When multiple vehicles are charging simultaneously, the output power is intelligently evenly distributed. The power cabinet can be centrally arranged in the corner area of the distribution room and station. The charging terminal is compact in size, and the parking space only occupies a small amount of ground space. It is suitable for high-density centralized charging, large-scale electric heavy-duty trucks, mixer trucks, and port trailers for 24-hour uninterrupted energy replenishment scenarios. From the perspective of site space and installation conditions, for large logistics parks, mining sites, and port battery swapping stations with compact space, dense parking arrangements, and no independent distribution rooms, cabinet type split charging piles are preferred. Power cabinets are centrally stored to reduce equipment occupation in the parking area, and more charging terminals can be arranged under the same transformer capacity to improve parking utilization; The underground garage of the shopping mall, highway service area, small enterprise fleet, and scattered public parking spaces in the city have an open space, few parking spaces, and no supporting power distribution rooms. Therefore, a column integrated charging pile can be directly selected without the need to renovate the power distribution civil engineering. The single pile can be installed independently and flexibly, and new equipment can be added in batches in the later stage, which is suitable for small-scale and decentralized charging point construction. According to the matching power configuration of charging vehicle types and operational efficiency, passenger cars, light electric logistics vehicles, and short distance shuttle buses with a battery capacity of less than 300kWh and a dwell time of 30-60 minutes are equipped with 120kW/180kW column integrated dual gun charging piles. A single unit can serve two small cars at the same time, with lower procurement and construction costs, meeting daily rapid energy replenishment needs; Electric heavy-duty trucks, electric dump trucks, electric tractors, and large buses, with battery capacities ranging from 450kWh to 600kWh, and an average daily turnover of more than 50 vehicles at the station, require high-power continuous fast charging. The CAMC cabinet type split charging stack system is selected, supporting dynamic power scheduling. During peak hours, it automatically outputs full power to the heavy-duty trucks to be charged, and during off peak hours, it evenly distributes multiple vehicles. Compared to multiple independent pillar piles, the power grid load is more stable, the transformer utilization rate is increased by more than 20%, and the long-term operating energy consumption loss is lower. Comparing the difficulty of operation and maintenance with the full life cycle cost, the column integrated charging pile is fully integrated, and the fault only involves a single device. It is easy to troubleshoot and repair, suitable for small and medium-sized stations with low daily charging capacity and insufficient operation and maintenance personnel. It requires less initial procurement and civil engineering investment, and has faster short-term cost recovery; The modular power cabinet design of the cabinet type split charging pile allows for individual module replacement if damaged, while the rest of the terminals are not affected and do not require complete machine shutdown for maintenance. It is suitable for large fleets and mining charging stations that operate 24 hours a day without interruption. Although the initial equipment and wiring construction investment is higher, the later expansion only requires the addition of charging terminals, without the need to repeatedly add rectifier hosts. The comprehensive operation and expansion cost of the large-scale station is better than that of the integrated column pile for 3-5 years. In terms of environmental adaptation and safety configuration, the CAMC series of column integrated charging piles adopt an integrated sealed sheet metal, a bottom raised base, and an independent heat dissipation air duct. They can operate stably in outdoor rainy and dusty environments, and are equipped with multiple protections such as overvoltage, overcurrent, leakage, high temperature, and collision power-off; The cabinet type split charging pile power cabinet supports indoor placement to avoid outdoor sun and rain damage. The charging terminal has been upgraded to enhance protection against salt spray and dust, and is suitable for harsh working conditions such as high dust and high corrosion in coastal ports and mining areas. Both types of equipment are compatible with GB/T and OCPP international communication protocols, supporting 4G remote monitoring, order billing, fault warning, remote OTA upgrade, and adapting to intelligent operation and management of domestic and overseas stations. Standardized selection plan for different scenarios, including small public charging stations, ground parking spaces in shopping malls/office buildings, short distance urban bus stations, and individual logistics fleets (up to 20 units per day): preferably 60-180kW integrated DC charging piles with columns, easy installation, flexible deployment, and controllable investment; Large logistics parks, exclusive mining dump truck stations, port electric tractor bases, long-distance high-speed large charging stations, centralized heavy-duty truck swapping and charging integrated stations: preferably equipped with 160-600kW cabinet type split charging pile systems, high-density gun distribution, dynamic power distribution, and support for large-scale expansion in the later stage; Underground parking garage, indoor enclosed parking lot, and old park renovation site, with narrow parking spaces that cannot accommodate large machines: equipped with power cabinets for indoor placement and small split charging terminals, saving parking space and reducing the risk of collision damage. Summary The choice between cabinet type charging piles or column integrated charging piles follows the principle of "small-scale decentralized point selection column integrated machine, large-scale high-density fleet station selection cabinet type split pile". If there is no distribution room, scattered parking spaces, and limited budget, priority should be given to column integrated charging piles; Dense parking spaces, high daily traffic volume, future expansion plans, harsh working conditions in mining areas/ports, priority given to cabinet type split charging systems. The two product lines of CAMC charging stations fully cover the charging needs of commercial, engineering, and public scenarios. They can provide one-stop services for station distribution survey, customized solutions, installation and commissioning, and global after-sales spare parts. They are suitable for green energy replenishment and upgrading of new energy transportation fleets in China, Southeast Asia, the Middle East, and Africa.

Clear charging requirements: The scenario determines the type of charging station Charging piles are the core supporting facilities for new energy vehicles, and the selection needs to first anchor the application scenarios and core requirements. Different scenarios have significant differences in charging speed, power, installation conditions, and functional configurations. Priority should be given to using AC slow charging stations for household private parking scenarios, with a power of 7kW (220V) as the main power source. The installation is convenient, the cost is moderate, and it is suitable for long-term charging at night. It can be fully charged by inserting a gun before bedtime and waking up in the morning, perfectly matching the daily commuting needs of household cars. Commercial public scenarios such as shopping malls, highway service areas, and logistics parks require the selection of DC fast charging piles with a power coverage of 30kW-350kW. The vehicle can be charged to 80% in 15-30 minutes, meeting the operational needs of high turnover and short-term stay. For dedicated scenarios such as enterprise fleets and bus stations, 11kW-22kW AC piles or 60kW-120kW DC piles can be selected according to the vehicle type (logistics vehicles, buses), taking into account both batch charging efficiency and cost control.   Core parameter matching: power, voltage and vehicle adaptation The charging power directly determines the charging efficiency and is the core indicator for selection. If the household scenario only supports 220V single-phase electricity, a 7kW AC pile is the optimal choice, suitable for the vast majority of household new energy vehicles, to avoid blindly purchasing 11kW piles and wasting success rates; If 380V three-phase electricity can be applied for, 11kW-22kW AC piles can shorten the charging time, suitable for multi car households. In commercial fast charging scenarios, the mainstream choice is 120kW DC piles, supporting 800V high-voltage platform models. It can travel 300km on a 10 minute charge, greatly improving the user experience; The supercharging station can use 160kW-240kW high-power DC piles, suitable for heavy-duty vehicles and high-end models. At the same time, it is necessary to confirm the maximum supported charging power of the vehicle to avoid the pile power far exceeding the vehicle's adaptation value, which may cause equipment cost waste. Safety and Qualification: The Core Threshold of Quality Assurance Safety is the primary prerequisite for selecting charging stations, and it is necessary to focus on verifying product qualifications and protective performance. Legitimate charging stations must comply with national standards such as GB/T 18487 and GB 39752, and key components must be certified to ensure electrical safety and communication stability. In terms of protection grade, the indoor installation must reach IP54, and the outdoor installation must reach IP55 and above. It is effective to prevent dust and water. In response to rainstorm, damp and other complex environments, coastal areas need to pay extra attention to salt spray prevention design. In northern low temperature areas, -30 ℃ low temperature start models are preferred. The safety protection function needs to be complete, with five core functions including overvoltage, overcurrent, leakage, lightning protection, and overheating protection. High end models can be equipped with ten layers of safety protection, which automatically shuts off when charging is abnormal, eliminating safety hazards.   Intelligent functions and operational requirements: adapting to different usage scenarios Intelligent functions directly affect the convenience of use and operational management efficiency, and can be selected as needed to avoid redundant configurations. The basic functions of household scenarios can meet the needs, such as card swiping start, timed charging (off peak electricity consumption to save electricity costs), and remote monitoring of apps, without blindly following gimmicks such as facial recognition and voice control. In commercial operation scenarios, it is necessary to strengthen intelligent management capabilities, prioritize models that support 4G/Wi Fi networking and cloud management platforms, achieve user QR code payment, order management, billing settings, remote fault diagnosis, support multi pile cluster management, and reduce manual operation and maintenance costs. Some high-end models are equipped with dynamic load management function, which can adjust power in real time according to the grid capacity, avoid transformer overload, and adapt to scenarios with limited grid capacity such as residential areas and commercial districts.   Installation conditions and costs: consideration of cost-effectiveness throughout the entire lifecycle Selection requires simultaneous evaluation of installation conditions and full lifecycle costs to avoid implicit expenses. Before installation, confirm the nature of the parking space (property/lease), property installation permit, meter capacity, and line distance. A 220V/32A meter is required for a household 7kW pile, and 380V industrial electricity is required for a DC pile. If the line distance is too long, it will increase cable costs. In terms of cost, the purchase cost of household communication poles is 2000-6000 yuan, which is easy to install and has low maintenance costs; The unit price of commercial DC piles is 100000 to 150000 yuan, but the daily service is 8-12 trips, and the cost can be recovered within 3-5 years. Priority should be given to brands that provide one-stop installation services and complete after-sales outlets to ensure standardized installation, timely fault response, and reduce post operation and maintenance risks.   CAMC Charging Pile Full Scenario Solution CAMC charging stations cover a full range of products including AC slow charging, DC fast charging, and high-power supercharging, catering to the needs of household, commercial, and dedicated scenarios.

With the continuous increase in the number of electric vehicles, the demand for charging stations as key supporting equipment is becoming increasingly prominent. CAMC wall mounted electric vehicle charging stations have become a common choice for households, communities, and public places due to their space saving and flexible installation characteristics. Its core function is to provide stable power input for electric vehicles, while reducing charging risks through multiple safety mechanisms, suitable for daily use in different climate environments. 1、Technical principles and core design: The shell is made of high-strength engineering plastic or metal material, with a protection level of IP54, which can effectively block dust intrusion and withstand the impact of splashing water, ensuring reliability during outdoor use. The storage temperature range covers -40 ℃ to 80 ℃, suitable for extreme weather conditions. Through various network connection methods such as 4G/WiFi/LAN, operators can conduct remote monitoring, real-time data statistics, and fault diagnosis anytime and anywhere through cloud platforms. More importantly, it fully complies with the OCPP 1.6J international standard protocol and can be easily integrated into mainstream charging operation platforms. Whether it's setting usage time and electricity prices, managing user permissions, or performing large-scale firmware upgrades, all can be done with just one click in the background. 2、Safety protection and usage regulations: The charging station is equipped with overvoltage protection, undervoltage protection, and leakage protection devices. When the grid voltage is abnormal or the charging interface is short circuited, the system will cut off the power supply within 0.1 seconds to avoid equipment damage or fire risks. When operating, users need to use the original charging cable and ensure that the vehicle is compatible with the charging station interface. During installation, it should be fixed on the load-bearing wall by professional personnel to avoid tilting or shaking. Regularly check the cleanliness of the interface during daily use to prevent poor contact caused by oxidation of metal contacts. 3、Performance advantages and technological highlights: Compared to traditional charging devices, this type of charging station has a faster response speed, with an interval of no more than 3 seconds from inserting the interface to starting charging, reducing user waiting time. Its charging performance stability has been rigorously tested, and after 24 hours of continuous operation, the output voltage fluctuation range is controlled within ± 1% to avoid damage to the battery due to unstable voltage. In terms of seismic resistance, by optimizing the internal structural layout, even in the event of slight vibrations (such as vehicles passing nearby), key components can still maintain normal working conditions. In addition, the core highlight of this charger lies in its unique power configuration: it is equipped with two completely independent 11kW charging guns, with a total power of up to 22kW. This means that it can serve two electric vehicles at the same time, just like laying two parallel lanes for a charging station. 4、Environmental characteristics and applicable scenarios: The charging station meets green environmental standards, emits no harmful gases during operation, and reduces power loss by optimizing the energy conversion efficiency (usually above 95%). It supports off peak charging function, and users can set the automatic start during the low valley electricity price period at night, further reducing electricity costs. Applicable scenarios include residential areas, office parking lots, commercial complexes, etc., especially suitable for areas with limited space but concentrated charging demand. Through customized services, we can also provide bulk deployment solutions for logistics fleets and shared electric vehicle operators.
