Status | Condition | Action |
---|---|---|
Normal | Min Cell Temp > UTD:Threshold OR charging | SafetyAlert()[UTD] = 0 |
Alert | Min Cell Temp ≤ UTD:Threshold AND Not charging (that is, BatteryStatus[DSG] = 1) | SafetyAlert()[UTD] = 1 |
Trip | Min Cell Temp ≤ 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 Min Cell Temp ≥ UTD:Recovery | SafetyStatus()[UTD] = 0 OperationStatus()[XDSG] = 0 |
