The main communication methods of AC ev charger

The AC Charging station only provides power output and has no charging function. It needs to connect the on-board charger to charge the electric vehicle. Due to the lack of a charger module on the AC pile, charging is completed by the on-board charger, so there is generally no need for CAN port communication with BMS. The main communication mainly includes RS485 and Wifi/GPRS.

1. RS485: The communication between the electricity meter and the control unit is usually connected through RS-485 to complete electricity statistics, consumption, etc.

2. Wifi, GPRS, Industrial Ethernet, etc.: mainly connected with the network, charging APP, etc. to realize remote monitoring and control.
