VCFRONT_a344_pcsFastTripSlope
Description
The front vehicle controller (VCFRONT) detects the electrical current flowing through the power conversion system (PCS) eFuse has equaled or exceeded a current slope value (rate of change) of 120A per millisecond.
Condition
The PCS eFuse current slope value equals or exceeds 120A per millisecond.
Clear Condition
The PCS eFuse current slope value is below 120A per millisecond.
Potential Impact
The eFuse circuit may open (trip), interrupting low voltage power supply to the PCS. This could make PCS functions limited or unavailable, and could interrupt precharging of the high voltage (HV) bus .
