| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
Calculated Amp-hour Capacity (CAC) difference of bricks within a module exceeds acceptable threshold. This results in reduced battery performance and limits maximum range. Vehicle enters Battery Management System (BMS) limp mode.
|
The estimated imbalance between the average CAC and minimum CAC within a single module exceeds the alert set threshold (CAC imbalance is not within acceptable range)
|
BMS limp mode is triggered, with another alert present to indicate this condition.
|
|
|
The battery management system (BMS) detects that the calculated Amp-hour capacity (CAC) difference between bricks within a single module exceeds the acceptable threshold, which may reduce battery performance.
|
The BMS detects that the estimated CAC imbalance between the average CAC and the minimum CAC of bricks within a single module exceeds the acceptable threshold
|
Reduced maximum range and limited charging performance.

|
|
A given brick has an alpha signal below the alert alpha threshold.
|
The computed alpha estimate for a brick is repeatedly below the alert alpha threshold. The threshold comes over the Controller Area Network (CAN) via signal MCU_dSocAlertThreshold.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The battery management system (BMS) detects a condition internal to the high voltage (HV) battery that requires the max allowed brick voltage to be limited.
|
HVBATT_w724_deltaSocWeakShort is set and (UI_dSocAlertEnable==1 or dSocAlertEnabledByDefault==1).
|
The target max brick voltage for charge is limited to the voltage corresponding to 50% SOC.
|
|
|
A module temperature is above the warning temperature limit
|
A module temperature is above the warning temperature limit for X duration (in seconds)
|
Power/drive limits may be reduced
|
|
|
Warns if the shunt current (discharge or charge) is above max current limit.
|
The shunt current (discharge or charge) is above max current limit.

|
|
The High Voltage System (HVS) bus is in the error passive state.
|
The HVS bus is disconnected or is experiencing a condition affecting its functionality, causing it to enter the error passive state.
|
The HVS bus may be unable to communicate with other components, which will lead to vehicle being unable to drive or charge.
|
|
|
The High Voltage System (HVS) bus is in the BusOff state.
|
HVS bus is experiencing a condition affecting its functionality, causing it to enter the BusOff state.
|
The HVS bus is unable to communicate with other components, which will lead to vehicle being unable to drive or charge.
