Charging specification cable models used in global charging stations

China [CN]

Description: From the current situation of new energy electric vehicle cables, the charging specification cable models used in global charging stations vary depending on factors such as region, charging pile type, power demand and installation environment. Therefore, there is no unified standard. Applicable cables are selected through local application standard models, such as: national standard, European standard and American standard, etc. However, some common charging station cable models and their applicable scope can be summarized according to general conditions and common specifications.

Overview of cable models: The cables used in charging stations are usually composed of multiple parts such as conductors, insulation layers, shielding layers and sheaths. The materials and specifications of different parts will affect the performance and applicability of the cables. Common cable models include but are not limited to the following:

Copper core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable (such as ZC-YJV); Product features: It has good flame retardant and electrical properties and is suitable for a variety of charging scenarios. Various specifications, such as 3x6 square millimeters, 3x10 square millimeters, 3x25 square millimeters, etc., are selected according to the power and distance of the charging pile.

RVV or RVVP type cable: mostly used for AC charging piles, suitable for lower power charging needs. RVV cables are generally used for 2-8 amp charging piles, and the cable diameter is smaller; RVVP cables are suitable for slightly higher power charging piles.

Cable model selection basis:

Charging pile power: The power of the charging pile directly determines the specifications of the required cable. High-power charging piles require cables with larger cross-sectional areas to ensure sufficient current transmission capacity.

Safety performance: As a key part connecting the power supply and the vehicle, the safety performance of the cable is crucial. Attention should be paid to the safety indicators of the cable such as flame retardancy, temperature resistance, and voltage resistance.

In summary: The charging specification cable models used in charging stations around the world vary due to many factors, and it is impossible to give a single standard answer. When selecting cables, the power, distance, use environment, and safety performance of the charging pile should be considered comprehensively, and the local power standards and equipment requirements should be referred to to select the appropriate cable model. At the same time, with the rapid development of the electric vehicle market and the continuous advancement of technology, the specifications and performance of charging pile cables will continue to be updated and improved.
