Battery Management System （BMS ）

Voltage Protection
Discharging Low Voltage Protection:
When any battery cell voltage is lower than the protection value during discharging, the over-discharging protection starts, and the ALM light always on. Then battery system stops supplying power to the outside. When the voltage of each cell recovers to rated return range, the protection is over.
Charging Over Voltage Protection:
When total voltage or any battery cell voltage reaches the protection value during charging, battery stops charging. When total voltage and all the cell voltage recover to rated return range, the protection is over.

Temperature Protection
Less/Over temperature protection in charging：
When battery’s temperature is beyond range of 0ºC~+55ºC during charging, temperature protection starts, device stops charging.The protection is over when it recovers to rated return range.

Less/Over temperature protection in discharging：
When battery’s temperature is beyond range of -20ºC~+55ºC during discharging, temperature protection starts, device stops supplying power to the outside.
The protection is over when it recovers to rated return range.

Other Protection
Short Circuit Protection:
The battery does not allow external short circuit, which will damage the BMS.

CAUTION
Battery’s maximum discharging current should be more than load’s maximum working current.
