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).
