Onboard charger defect

[Art]

I did not understand your figures.. EVSE's showing 40 kW?
However the charging problems sound familiar to me. OBC and converter changed.

Has your wallbox been fixed? I’ve run in the same issues as you, woke up this weekend with no power in the house. Taycan stopped charging at 7 am around 80 %. I turned the power back on but charge fault in the Taycan. Car is now at the dealer to replace the OBC. But I also have the same issue with my wallbox pulsar pro, the charger shows over 40kW… So if you got it fixed, I’m very curious how.

I ended up installing a new one. They first changed the power meter but that didnt solve it. The charger worked but I couldnt register anymore wich was necessairy for my company. I didnt forward the costs to Porsche because I didnt want to give them a possibilty to blame Wallbox for the defect in the car and void the warranty.

Yes correct EVSE showing 40 kW charging rate after the power out by the Taycan. Which is impossible with my 22 kW EVSE of course. Out CLA hybrid shows the kW in the charge screen and it was still giving 3,6 kW like it should but the Wallbox app indicated it was 40 kW. Something wrong with the internal meter in the Wallbox after the short circuit and not giving the correct numbers anymore.

Just like McgR said, the max 22kW charger is showing a charging rate which is impossible.

OK. So a SW/FW bug then. I suppose you use 3x400V 16A plug where max. is the mentioned 11 kW.
So I had similar issues - coming back from Porsche Espoo (260 km) and needed to take few kWh's but none of the DC chargers worked. Charged it with AC 11-22 kW during ca. 10 days and returned to airport parking from where they picked it and returned a loaner RWD.
The car was returned after 4 and half months repair.

Those were the only 10 days I had my car usable year 2024. After this it has been stored until 'Consumer disputes board' decide if this is new normal with repairs.

Hopefully you can see text captions in English - they seem to be mostly correct.
