Meet the specifications of the cables used in parking garage charging piles

China [CN]

The thickness of the electric vehicle charging power cable needs to be selected comprehensively according to factors such as the charging installation scenario. The following are specific suggestions provided by professional cable manufacturers:

Conventional charging scenarios: High-power charging scenarios (fast charging/high-power piles) 40kW and above charging piles: 16 square millimeters (1*16+1*10mm²) or higher specifications of special cables are required. 380V three-phase charging piles: 5-core 6 square millimeters (5*6mm²) or 5-core 10 square millimeters (5*10mm²) cables are recommended to ensure three-phase balance and stability.

Reference cases for different models: Hybrid/7kW home piles: 6 square millimeters cables are recommended. Home slow charging (7kW): 4 square millimeters and above cables are required, and fast charging (380V) requires special three-phase cables. Other new energy sources: Public fast charging piles recommend 3*16mm² cables, and home piles can match 4-6 square cables.

In summary, it is recommended to give priority to 4-6 square millimeter cables to cover mainstream charging needs, and upgrade to 10 square millimeters or more for long-distance or high-power scenarios. At the same time, pay attention to the cable standards (such as YJV/RVV) and installation specifications. The specific details can be further confirmed in combination with the model manual and the requirements of the car company.
