Signal Name Description Condition Impact Important
Pyro fuse deployment was triggered but did not execute.
Software did not successfully deploy the pyro
Pyro deployment may be compromised
No
Pyro fuse deployment was triggered by firmware.
Pyro fuse deployment was triggered by firmware
Subpack is offline
No
Pyro fuse may not have cleanly blown, post-mortem diagnostic.
Energy and/or charge delivered to the squib were out-of-tolerance
Pyro deployment may be compromised
No
Pyro fuse is faulted.
Leak test failure or Switch test failure or other failure
Pyro fuse deployment ability is compromised
No
The high voltage processor (HVP) is not receiving messages from the vehicle gateway (GTW) on the high voltage system (HVS) controller area network (CAN). HVP functions that depend on messages from the GTW may be unavailable, or their performance may be affected.
The high voltage processor (HVP) is not receiving messages from the vehicle gateway (GTW) on the high voltage system (HVS) controller area network (CAN).
High voltage processor (HVP) functions that depend on messages from the vehicle gateway (GTW) may be unavailable, or their performance may be affected.
No
Pyro squib is disconnected or open-circuit, but pyro circuit is otherwise nominal.
Pyro squib is missing resulting in open-circuit resistance
Pyro fuse deployment ability is compromised
No
Warns if the pack charge current is above max charge current limit
The pack charge current is above max charge current limit for X duration (in msec)
The DC charging will end and contactors may open immdediately or pyro may disconnect
No
Fault impacting the pyro sub-system.
Pyro operations could not be started
Pyro cannot be deployed
No
Energy-reserve circuit has a failure.
Voltage of the energy-reserve is out-of-tolerance
Pyro deployment may be compromised
No
Indicates a BMB reference voltage has continuously been out of bounds.
Any BMB reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage
Other BMB voltage signals will be substituted given the reference voltage is unreliable
No
Indicates a mismatch between a stack voltage and the sum of its brick voltages.
Any BMB continuously has a stack voltage that doesn't align with the sum of its brick voltages within the in-bounds tolerance
BMB stack and brick voltage signals will be substituted
No
HVPACK cannot talk to all BMBs.
A communication issue with the BMB daisy chain is detected
May indicate a loss of BMB sensor data
No
A brick voltage is below minimum voltage limit
A brick voltage is below minimum voltage limit for X duration (in seconds)
The conactors may open immdediately or pyro fuse may blow
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
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
Passive pyro reference is out-of-tolerance.
Passive pyro reference is out-of-tolerance
Passive pyro fuse thresholds are affected
No
