Energy Storage Group Control Unit(ESGU)




Function Description of Energy Storage Group Control Unit(ESGU):

System power-up self-test, including all sensors,system status,etc.

Many kinds of parameters can be detected, such as the battery pack voltage, current, temperature, and so on.

Test insulation from battery positive and negative to the chassis.

Control main contactors and detect main contactor’s feedback signal.

Alarm under exception and protect and control hard contract.

CAN and RS485 bus communicate.
