HOW TO repair a Fiat500e 2015 us california „Service Charging System“

I own a Fiat 500e that no longer charges.

Current Problem Desciption:
After nine failed flash attempts using wiTECH 2.0 (online dealer account), the BPCM now appears to be stuck in a protection/inconsistent state.

Next Step: Change (or „Flash“) the BPCM Module and look for the „real fault“
