10. Way of working

BMS sends control information (message 1) to the battery at a fixed interval of 1s.
After the charger receives the message, It will Stream settings to work through the
received voltage and current . If no message is received within 5 seconds, it
enters a communication error state and turns off the output. Charger sends
