Battery Management System (BMS)

Voltage Protection

Discharging Low Voltage Protection
When the battery cell voltage is lower than the rated protection value or a total voltage below 42V during discharge over-discharge protection is activated and the battery alerts the user via alarm. The battery will then isolate and cut off. When the voltage of each cell recovers to the rated value and the total voltage is restored to above 45V, the protection resides.

Charging Over Voltage Protection
When charging, the system stops charging when the total voltage of the battery pack is higher than 54.75V or the voltage of any single cell reaches the protection value. When the total voltage returns to below 52V and the cell voltage returns to below the rated protection value, the protection is released.

Current Protection

Over Current Protection in Charging
When the charging current is greater than the protection value an internal alarm is activated and the system stops charging. After the system delays the rated time for 1 min, the protection is released.
Over Current Protection in Discharging:

When the discharging current is greater than the protection value, the battery signals an alarm and the system stops discharging. After the system delays the rated time for 1 min, the protection is released.

Temperature Protection
Less/ Over temperature protection in charging:
When the battery’s temperature is beyond the range of 0~+45 during charging, temperature protection is enforced and the device stops charging. The protection is released when it recovers to the rated return range.

Less/Over temperature protection in discharging:
When the battery’s temperature is beyond the range of -10 ~+45 during discharging, temperature protection starts and the device stops supplying power to the outside. The protection is released when it recovers to the rated return range.

Other Protection

Short Circuit Protection:
When the battery is activated from the off state, if a short circuit occurs, the DC circuit breaker will act ﬁ rst. If the DC circuit breaker does not operate, the BMS will start the short circuit protection function and cut off the external voltage output.

Self Shutdown:
When a device connects to no external loads for over 72 hours the device will activate dormant standby automatically. Caution:
The maximum working current of the load which needs to be powered should be less than the maximum discharge current capacity of the battery system
