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?
Choose the CAMC IP65 outdoor wall mounted model, which comes with a waterproof structure and does not require additional rainproof enclosures, saving installation space and costs.
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.
