7、Power On/Off

Press the button to turn on/off. Press the button when powered off to turn on. Press and hold the button for 3s when powered on to turn off.

8、Communication

       、RS232 communication

The BMS can communicate with host computer via RS232 interface to monitor battery information including voltage, current, temperature, status and production info. Default baud rate is 9600bps。

       、CAN communication

Default CAN communication baud rate is 250k

       、RS485 communication

There are two RS485 communication interfaces. One is paralleled out to two interfaces for monitoring battery group info. Default baud rate is 115200. The communication address can be set via DIP switch with address range 0~15 to poll data from all battery packs.
