PCS2_a112 — Chg Input V Drop Too High

Full alert identifier: PCS2_a112_chgInputVDropTooHigh

Message shown in the car

Charging stopped due to large voltage drop Remove extension cords / Have wiring inspected

Alert description

During the ac charging, the measured rms voltage across the lines has decreased below the high impedance detection RMS voltage threshold when compared to the RMS voltage at the start of AC charging

Potential impact

AC charging functionality may be limited or paused

Set condition

The root mean squared (RMS) voltage across the lines has decreased below the high impedance detection RMS voltage threshold

Clear condition

The root mean squared (RMS) voltage across the lines has no longer decreased below the expected RMS voltage threshold
