Page 17: Protections
4 Protections 1. Cell/Overall Over-charge Protection When the actual voltage of any cell/overall is higher than the over-charge protection voltage, and the duration reaches the over-charge delay, the battery enters the over-charge protection state. The charging MOS and charging current limiting module are turned off, and the battery cannot be charged. Protection Recovery: When the actual voltage of any cell/overall drops below the overcharge recovery voltage, the over-charge protection state is released. - Page 18 Protection Recovery: The cell temperature drops to the high temperature recovery value. 6. Charge/Discharge Low Temperature Protection During the charging and discharging process, when the NTC detects that the cell temperature is lower than the low temperature protection value, the charging or discharging MOSFET is turned off. In this state, the battery cannot be charged or discharged.
