T/GAEPA 002-2023 Digital communication protocol between electric vehicle supercharging equipment and vehicle

Scope

Main technical content: This standard specifies the definitions of the communication physical layer, data link layer, and application layer based on the controller area network between the charging communication controller of the electric vehicle supercharging equipment and the vehicle charging communication controller. The standard comprehensively stipulates the scope of application and main contents of the communication protocol, clarifies the format and supported working conditions of the communication protocol, standardizes the messages in the low-voltage auxiliary power-on and charging handshake stage, the parameter configuration stage, and the charging stage of the protocol, and compiles the flowcharts of the interaction between the charger and the vehicle in each charging stage, which meets the actual situation of communication between electric vehicles and supercharging equipment and ensures the realization of the superfast charging function. In addition, this standard also standardizes the digital communication protocol between electric vehicle supercharging equipment and vehicles, which can solve the compatibility problem between supercharging vehicles and supercharging equipment, improve the user charging experience of supercharging stations, fill the gap in the communication protocol standard of high-power charging facilities, reach the advanced level in China, and help promote the comprehensive construction of electric vehicle supercharging facilities, which is of great significance for the promotion of supercharging vehicles and supercharging technology
