BMS_u018 — SOC Imbalance Limiting
Full alert identifier: BMS_u018_SOC_Imbalance_Limiting
Message shown in the car
Maximum battery charge level reduced OK to drive - Schedule service
Alert 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.
Potential impact
The target max brick voltage for charge is limited to the voltage corresponding to 50% state of charge (SOC).
Set 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.
