| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The battery management system (BMS) detects an out-of-bounds module voltage reference.
|
Any battery monitoring board (BMB) reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage.
|
This alert is primarily informational. Other BMB voltage signals will be substituted given the reference voltage is unreliable.
|
|
|
The battery management system (BMS) detects an uncontrolled regen event.
|
The BMS detects regen power above the maximum threshold while in drive.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects that high voltage (HV) isolation is too low while pack contactors are closed.
|
The BMS has 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) reports a communication issue with the high voltage processor (HVP).
|
The BMS is not receiving the expected messages from the HV system.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects that one of the pack contactors is welded.
|
The BMS detects that one of the pack contactors is welded.
|
This alert is primarily informational.
|
|
|
The High Voltage Processor (HVP) error pin is asserted on Battery Management System (BMS) input.
|
Analog input pin from the HVP is raised pointing to the HVP Error line being asserted.
|
There is a temporary loss of High Voltage (HV) functions.
|
|
|
The battery management system (BMS) does not have enough power to provide low voltage (LV) support.
|
The BMS detects that the high voltage (HV) state of charge (SOC) is too low to support the LV system.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects that both of the pack contactors are welded.
|
The BMS detects that both of the pack contactors are welded.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
The battery management system (BMS) detects that one of the FC link contactors is welded.
|
The BMS detects that one of the FC link contactors is welded.
|
This alert is primarily informational.
|
|
|
The battery management system (BMS) detects that both of the FC Link contactors are welded.
|
The BMS detects that both of the FC link contactors are welded.
|
Inability to charge, drive, or support the low voltage (LV) system
