Appropriate matching of charging connection equipment

The role of electric vehicle charging cables in charging piles is to connect electric vehicles and charging, transmit energy and signals, and realize the charging of electric vehicles.

The matching principles of electric vehicle charging cables and charging piles include the following aspects:
Interface standardization: In order to ensure that electric vehicles of different brands can use the same charging pile for charging, the International Organization for Standardization and governments of various countries have issued a series of specifications to unify the shape, size and electrical characteristics of charging interfaces, such as the Mennekes standard in Europe, the SAE J1772 standard in the United States, and the GB/T standard in China.

Communication protocol: Two-way communication is required between charging piles and electric vehicles to determine information such as charging status, charging speed, power and faults. The communication protocol includes the physical layer, data link layer and application layer, such as the IEC 61850 standard in Europe, the IEEE 802.11 standard in the United States, and the CAN standard in China.

Safety protection: Both the charging cable center and the on-board charger center have protection measures, including overload protection, short circuit protection, over-temperature protection, leakage protection, etc. At the same time, during the plugging and unplugging process, the charging cable and charging pile will automatically power off to ensure user safety.

Charging mode: Charging modes include DC fast charging, AC fast charging and AC slow charging. According to different charging modes, the electrical characteristics between charging piles and electric vehicles are different, and corresponding matching equipment is required to achieve charging.

Through the above matching principle, electric vehicle charging cables can achieve safe, efficient and standardized charging services in charging piles, which facilitates the promotion and popularization of electric vehicles.
