SLUUBT5C November 2018 – June 2021 BQ40Z80
The BQ40Z80 device has an overtemperature protection for cells in the DISCHARGE or RELAX state (that is, non-charging state with BatteryStatus[DSG] = 1).
Status | Condition | Action |
---|---|---|
Normal | Max Cell Temp < OTD:Threshold OR charging | SafetyAlert()[OTD] = 0 |
Alert | Max Cell Temp ≥ OTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) | SafetyAlert()[OTD] = 1 BatteryStatus()[TDA] = 1 |
Trip | Max Cell Temp ≥ OTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) for OTD:Delay duration | SafetyAlert()[OTD] = 0 SafetyStatus()[OTD] = 1 BatteryStatus()[OTA] = 1 OperationStatus()[XDSG] = 1 if FET Options[OTFET] = 1 BatteryStatus()[TDA] = 0 |
Recovery | SafetyStatus()[OTD] AND Max Cell Temp ≤ OTD:Recovery | SafetyStatus()[OTD] = 0 BatteryStatus()[OTA] = 0 OperationStatus()[XDSG] = 0 BatteryStatus()[TDA] = 0 |
