Stop charging
3.65V
Stop charging when cell voltage reaches 3.65 V
First overcharge protection
≥3.69V
Stop charging when cell voltage reaches 3.69 V
Second overcharge protection
≥3.8V
When the battery voltage reaches 3.8V, the BMS is forced to terminate charging, and the BMS should be locked until technicians solve the problem.
Stop discharge
Minimum 2.6V
Minimize the discharging current when cell voltage reaches 2.6 V.
First over discharge protection
Minimum 2.5V
Stop discharging when cell voltage reaches 2.5V
Second over discharge protection
Minimum 2.0V
When the cell voltage is less than 2.0V, the cell should be charged back to 50% SOC at 0.1C in time, and the BMS should be locked until technicians solve the problem.
Short circuit protection
No short circuit allowed
When a short circuit occurs, the battery (cell) is disconnected by the overcurrent protection device.
Charging time out limit
Charging completes within 8 hours
Stop charging if changing time exceeds specification
