Charging Error After Battery Recall Service

[AstroKen]

My 2023 Taycan 4s fell into the group for the "High voltage batteries may short circuit" recall. After the recall service, my car will not charge properly. I get the message "Charging error." Or error: charging not possible. I never had any issues before the recall. The profile was set to optimized charging at 80% and that worked fine for 2 years before the recall.

The vehicle starts charging okay but after an hour or so I get the error message. Example: at 2:21 pm the battery was at 20% and the mileage was 40 miles when I started charging. At 3:17 pm I got the Charging error with the battery at 26% and mileage at 53 miles.

After a fruitless trip to the dealer to remedy the problem, I am still having problems with both direct charging and timed charging.

The dealer reprogrammed the high voltage batteries and got it to charge from 16% to 87% and found no faults related to charging. After I got the car home, I was getting the same charging errors as before. I have a Level-2 50A circuit for charging. My wife's Volvo XC40 recharge charges fine, so I think I can rule out problems with the charging infrastructure of the house.

Has anyone seen such a problem? Any suggestions for me to try?

How does AC charging work at Level 2 chargers other than the one at your house?

The level 2 charger at the dealer worked and got me to 85%. I wonder if the Porsche Mobile Charger + is having grounding problems? I read in the PMC+ manual that it is possible to disable ground monitoring. I will try that next. Or maybe ask the dealer to let me try a different PMC+ unit.

Do not rely on any Porsche-branded EVSE in the US. Get something else.

Update: I had an electrician check my charging setup and he replaced the socket with a new EV-rated one. That did the trick. I noticed that the plug would get warm while charging with the old socket but the plug is cool as can be with the new, more robust socket. Now the Taycan charges as it should!
