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. 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 ：
When the charge current is higher than the protection value, the system stops charging.
Protection is released after rated time delaying or charging current released.
Over Current Protection in Discharging
：
When the discharge current is higher than the protection value, the system stops
discharging. Protection is released after rated time delaying or discharging current
released.
2.4.3 Temperature Protection
Low/Over temperature protection in charging ：
When battery
'
s temperature is beyond range of 0
℃
~+55
℃
during charging, temperature
protection is activated, device stops charging.
The protection is over when temperature back to rated working range.
