PCS2_a119_useMaxCapForHvImpedanceEstimation

The Power Conversion System (PCS) detects the initial high voltage (HV) bus voltage is too high to measure capacitance, so it must rely on the maximum possible capacitance value instead for HV bus impedance estimation.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

None displayed

Impact

PCS may underestimate the HV bus impedance.

Description

The Power Conversion System (PCS) detects the initial high voltage (HV) bus voltage is too high to measure capacitance, so it must rely on the maximum possible capacitance value instead for HV bus impedance estimation.

Cause

The initial HV bus voltage is too high to measure capacitance, so PCS must use maximum possible capacitance value to estimate HV bus impedance.

Clear condition

The DCDC converter is commanded to shut down or receives a new request to precharge the HV bus.
