Signal Name Description Condition Impact
Incorrect or Missing configuration block programmed
The HVP config block may be missing, incorrect, or unsupported
The HVP is unable to initialize configuration parameters
One or more fast charge (FC) or pack contactors in the high voltage battery failed to open when requested
The contactor(s) do not open when requested to open immediately
Pyro fuse will blow, which will cut off all high voltage (including charging)
The shunt measurement ASIC is not producing data
Timeout on expected communication
Shunt readings are stale
A battery pack brick voltage is below the under voltage fault limit
A battery pack brick voltage is below the under voltage fault limit for X duration (in seconds)
Inability to enter drive or support the low voltage (LV) system
A battery pack module temperature is above the warning temperature limit
A battery pack module temperature is above the warning temperature limit for X duration (in seconds)
Power/drive limits may be reduced
Positive contactor opened unexpectedly due to insufficient coil drive current.
Contactor state exited ECONOMIZED because coil current was too low.
Vehicle will stop charging.
Tried to close negative contactor but failed because a voltage match was not maintained.
Contactor state timed out of PULLED_IN because a voltage match was not maintained.
Negative FC contactor will remain open.
Tried to close positive contactor but failed because a voltage match was not maintained.
Contactor state timed out of PULLED_IN because a voltage match was not maintained.
Positive FC contactor will remain open.
Tried to close negative contactor but failed because the coil drive current was too low.
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
Negative FC contactor will remain open.
Tried to close positive contactor but failed because the coil drive current was too low.
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
Positive FC contactor will remain open.
Did not try to close negative contactor because a voltage match was not achieved.
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
Negative FC contactor will remain open.
Did not try to close positive contactor because a voltage match was not achieved.
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
Positive FC contactor will remain open.
The battery management system (BMS) detects that the high voltage (HV) isolation contactor closed below the warning threshold.
The BMS detects that the HV isolation was below the warning threshold when pack contactors closed.
This alert indicates that HV isolation is low, but above the sufficient level for vehicle operation.
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 Range Extender Battery Management System (BMS) or High Voltage Controller (HVCON) detects the pyro was deployed by the passive pyro circuit.
The passive pyro circuit deploys the pyro.
The High Voltage (HV) pack may be blocked, which will prevent the vehicle from driving or charging.
The Range Extender Battery Management System (BMS) or High Voltage Controller (HVCON) detects the pyro was deployed by vehicle firmware.
The pyro was deployed by vehicle firmware.
The High Voltage (HV) pack may be blocked, which will prevent the vehicle from driving or charging.
The Range Extender Battery Management System (BMS) or High Voltage Controller (HVCON) detects there was an attempt to deploy the pyro, but the attempt was unsuccessful.
Vehicle firmware could not successfully trigger a pyro deployment, or there was an attempt to deploy the pyro while the deployment test was actively running on the pyro.
The vehicle may be unable to drive or charge.
A battery pack brick voltage is below the open circuit voltage (OCV) undervoltage limit at rest.
A battery pack brick voltage is below the under voltage OCV limit for X duration (in seconds) while contactors are open.
Drive may be blocked.
A battery pack brick voltage is below the over discharged voltage limit
A battery pack brick voltage is below the over discharged voltage limit for X duration (in seconds)
The vehicle may not drive.
A battery pack brick voltage is above the fault voltage limit
A battery pack brick voltage is above the fault voltage limit for X duration (in seconds)
The vehicle may not drive or charge.
