Charger interface: The connection between the charger and the electric vehicle should include the following parts: high-voltage charging line, charging control guide line, charging control power line, charging monitoring communication connection line, and grounding protection line. At the same time, the charger should reserve a communication interface connected to the charging station monitoring system.
Charger communication requirements: It is recommended to use CAN bus and CAN2.0 protocol as the communication bus form and communication protocol of the charger.
The communication content includes: the relevant technical parameters of the power battery unit, module and assembly, the state parameters of the battery during the charging process, the working state parameters of the charger, and the basic information of the vehicle.
