Signal Name Description Condition Impact Important
Shunt bar temperature is too high.
Shunt bar temperature is too high
Reduced accuracy and physical damage
No
The shunt measurement Asic is not producing data.
Timeout on expected communication
Shunt readings are stale
No
Battery subpack 1 Pyro fuse deployment was triggered by firmware but did not successfully execute.
Pyro fuse deployment was recently triggered and failed to execute.
Pyro deployment may be compromised.
No
Data integrity loss due to BMB chain double break.
A prolonged communication issue with the BMB daisy chain that is known to cause a loss of BMB sensor data is detected
The HVPACK is likely performing BMB sensor data substitution to replace data missing due to the communication issue
No
A bmb die temperature is above maximum temperature limit.
A bmb die temperature is above maximum temperature limit for X duration (in seconds)
Brick balancing will be disabled
No
Indicates valid data is missing for one or more stack voltages.
One or more stack voltages are continuously detected as invalid
Stack voltage data is likely being substituted to replace invalid readings
No
Indicates valid data is missing for one or more brick voltages.
One or more brick voltages are continuously detected as invalid
Brick voltage data is likely being substituted to replace invalid readings
No
Sets immediately on SPI comms errors for visibility into the health of the comms interface.
On single SPI comms error with the asic
HvSenseAsicFault is at risk of being triggered soon
No
Sets immediately on SPI comms errors for visibility into the health of the comms interface.
On single SPI comms error with the asic
ShuntAsicFault is at risk of being triggered soon
No
Warns if the pack current (discharge or charge) is above max current limit.
The pack current (discharge or charge) is above max current limit.
The pyro disconnect will blow
No
Shunt thermistor is not connected.
Shunt thermistor reading is open-circuit
Subpack may not come online
No
The shunt measurement asic has a SPI communication fault or other internal fault.
Fault condition was set during SPI communications
Shunt readings are stale
No
The shunt measurement Asic is not producing data.
Timeout on expected communication
Shunt readings are stale
No
The HvSense measurement asic has a SPI communication fault or other internal fault.
Fault condition was set during SPI communications
HvSense readings are stale
No
The hvsense measurement Asic is not producing data.
Timeout on expected communication
HvSense readings are stale
No
The TCR Coefficient Calibrations are not being used.
The stored Shunt Bar Resistance was either invalid or the written gain was outside of tolerance.
The default TCR coefficients will be used. Shunt current measurement accuracy may be reduced.
No
The programmed Bar Resistance Calibration is not being used.
The stored Shunt Bar Resistance was either invalid or the written gain was outside of tolerance.
The default Shunt Bar Resistance will be used. Shunt current measurement accuracy may be reduced.
No
The programmed Shunt ASIC Calibration is not being used.
The stored Shunt ASIC gain was either invalid or the written gain was outside of tolerance.
The default Shunt ASIC gain will be used. Shunt current measurement accuracy may be reduced.
No
Hvpack is not receiving CAN messages from Hvlink.
Hvpack has not received a message from Hvlink in the MIA qualification time
Hvpack will not allow Hvlink to test the Battery Pack pyro while High Voltage is active
No
Incorrect or missing IP address programmed.
Hvpack IP address may be missing, incorrect, or unsupported
Hvpack is unable to initialize network data
No
