Alert Details

BMS_u018_SOC_Imbalance_Limiting

Description

The battery managed system (BMS) detects a condition internal to the high voltage (HV) battery that requires it to limit the maximum allowed brick voltage.

Condition

The BMS detects that the overall SOC imbalance (BMS_socCellMaxDbg - BMS_socCellMinDbg) exceeds the acceptable threshold.

Clear Condition

The BMS detects that the overall SOC imbalance (BMS_socCellMaxDbg - BMS_socCellMinDbg) is within the threshold.

Potential Impact

The target max brick voltage for charge is limited to the voltage corresponding to 50% state of charge (SOC).
