|---|---|---|---|
|
The battery management system (BMS) has detected an uncontrolled regen event.
|
The BMS detects regen power is above the maximum threshold while in drive.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects a high delta between the brick that needs the least amp hours (Ah) compared to the one that needs the most Ah.
|
The BMS has detected that the difference between the brick that needs the least amp hours (Ah) compared to the one that needs the most is above the maximum threshold.
|
This alert is primarily informational and is used for logging purposes. It may indicate a poorly balanced pack, which should go away after the pack is properly balanced.
|
|
|
The Battery Management System (BMS) detects a state of charge (SOC) imbalance between modules.
|
The BMS detects an SOC delta that is outside of the expected threshold between the minimum brick SOC and the average brick SOC of the pack, and the alert BMS_a164_Brick_SOC_Imbalance is not active.
|
No expected impact on vehicle functionality.
|
|
|
The battery management system (BMS) detects a state of charge (SOC) imbalance between bricks associated with the same module.
|
The BMS detects that the SOC imbalance between any two bricks associated with a module is above the warning threshold.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
The battery management system (BMS) has detected that contactors have undergone stress from a wide-open throttle (WOT) event.
|
The BMS detects that contactors have undergone stress from a WOT event.
|
This alert is primarily informational.
|
|
|
The battery management system (BMS) has detected that precharge was too slow to allow fast charge (FC).
|
The BMS detects that the voltage on the DC link bus is rising slower than it should be.
|
The vehicle cannot DC FC.
|
|
|
The battery management system (BMS) has detected that pack contactor degradation has exceeded the maximum threshold.
|
The BMS detects that the pack contactor stress estimate is above the warning limit threshold.
|
This alert is primarily informational and serves as an early warning of pack contactor degradation.
|
|
|
The battery management system (BMS) has detected that a brick is over-charged.
|
The BMS detects that a brick voltage is over the maximum threshold.
|
This alert is primarily informational and is used for logging purposes. It is intended to flag early overvoltage issues.
|
|
|
The battery management system (BMS) detects low high voltage (HV) isolation when pack contactors were closed.
|
The BMS has detected that the HV isolation dropped below the minimum warning threshold multiple times in a short period.
|
This alert is primarily informational and is used for logging purposes. It is intended to flag low isolation issues before they are serious enough to prevent driving.
|
|
|
The battery management system (BMS) has detected a battery monitoring board (BMB) voltage reference is unstable.
|
The BMS detects a BMB voltage reference is unstable.
|
This alert is primarily informational.
|
|
|
The battery management system (BMS) has detected a potential battery monitoring board (BMB) hardware issue related to the analog-to-digital converter (ADC) voltage reference (VREF).
|
The BMS has detected that several samples from the ADC do not match, which indicates a reference problem.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
The battery management system (BMS) has detected that the negative contactor is stuck or welded.
|
The BMS detects that the negative contactor is stuck or welded.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) has detected that the positive contactor is stuck or welded.
|
The BMS detects that the positive contactor is stuck or welded.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) has detected that high voltage (HV) isolation is too low while pack contactors are closed.
|
The BMS detects that HV isolation is below the warning threshold while contactors are closed.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects that it is taking too long to reach the target precharge voltage and prevents packs contactors from closing. This indicates that the voltage on the DC link bus rose more slowly than expected.
|
The BMS detects that the voltage on the DC link bus is rising slower than it should be. Alert log signal data provides information on the specific condition(s) detected.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) has detected that the length of time it took the vehicle to precharge was too short.
|
The BMS detected that the voltage on the DC link bus rose faster than expected.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) has detected that a brick is over-discharged.
|
The BMS detects that a brick voltage measured below the minimal threshold.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
A battery monitoring board (BMB) reports a brick under voltage event, indicating that the BMB has detected a brick voltage lower than the minimum allowed brick voltage threshold.
|
A brick voltage drops below the minimum allowed brick voltage threshold.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
A battery monitoring board (BMB) reports a brick over voltage event, indicating that the BMB has detected a brick voltage higher than the maximum allowed brick voltage threshold.
|

|
|
|
A battery monitoring board (BMB) reports a power-on reset event, indicating that the BMB may have previously been unavailable for communication with the battery management system (BMS).
|
Any BMB experiences a power loss or internal error that causes a power-on reset event.
|
Inability to charge, drive, or support the low voltage (LV) system
