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.
