SLUUAQ3A April 2016 – October 2022 BQ4050
The device has an undertemperature protection for cells in DISCHARGE or RELAX state (that is, non-charging state with BatteryStatus[DSG] = 1).
Status | Condition | Action |
---|---|---|
Normal | Temperature() > UTD:Threshold OR charging | SafetyAlert()[UTD] = 0 |
Alert | Temperature() ≤ UTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) | SafetyAlert()[UTD] = 1 |
Trip | Temperature() ≤ UTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) for UTD:Delay duration | SafetyAlert()[UTD] = 0 SafetyStatus()[UTD] = 1 OperationStatus()[XDSG] = 1 |
Recovery | SafetyStatus()[UTD] AND Temperature() ≥ UTD:Recovery | SafetyStatus()[UTD] = 0 OperationStatus()[XDSG] = 0 |
