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
