What are the global charging standards and charging interface types?

Currently, global charging standards are divided into three categories:

CCS joint charging: European standard-CCS 2 American standard-CCS 1

GB/T Chinese standard

CHAdeMO Japanese standard

The hardware difference is:

Combination of European and American standards: Type 1 and Type 2, evolved into Combo 1 and Combo 2, this charging mode allows you to use slow and fast charging at the same time. The American standard can be operated on the charging gun due to the inverter technology that converts DC to AC. Vehicles with this connection can increase the charging speed to the fastest charging speed. The main application areas are Combo 1 for North America, South Korea, Taiwan and other regions, and Combo 2 is used in Europe, South Korea, Southeast Asia, Australia and the Middle East.

GBT China DC and AC charging interface: The national standard is divided into two types of connectors: slow charging (AC) connector and fast charging (DC).

CHAdeMO Japanese charging interface: AC is similar to the American standard and DC is similar to the national standard, and it is the same as the national standard as the AC and DC split connector.

The differences in communication are:

The European standard – CCS 2 and the American standard – CCS 1 use the same control logic based on PLC communication. CCS 1 follows the SAEJ1772, SAEJ 2847 J2931 and other protocol standards, and CCS 2 follows the DIN 70121, ISO 15118 protocol standards, which are specified as System C.

The control logic of China DC and Japan DC is based on the CAN communication protocol, and follows the GB/T 27930 and JIS/TSD0007 protocol standards respectively.
