2.4 Battery Management System(BMS)

2.4.1 Voltage Protection

Low Voltage Protection in Discharging ：
When any battery cell voltage or total voltage is lower than the rated protection value during
discharging, the over-discharging protection is activated, and the battery buzzer makes an alarm
sound. Then battery system stops supplying power to the outside. When the voltage of each cell
back to rated return range, the protection is over.
Over Voltage Protection in Charging：
Battery will stops charging when total voltage or any battery cell voltage reaches the rated
protection value during charging stage. When total voltage or all cell back to rated range, the
protection is over.

2.4.2 Current Protection

Over Current Protection in Charging：
