Hi guys!

Hope you enjoy your Taycan's as much as I do!
Yesterday when the temperature was semi-low, hovering around 0 C, the car wouldn't start charging when I switched over to "Direct charging" in the app.
It was alternating between "Initializing" and "Charging" and then finally after 10 - 15 minutes it gave up displaying the message, "Charging Error".
I tried changing using the other charging port, but the same behaviour occured.
Eventually after an hour of fiddling, getting in and out of the car several times and changing back to my normal charge port it started charging.

I noticed that the battery temperature was much higher by that time, around 11 C.

Anyone else seen this kind of behaviour?

Regards

Joacim

Can you clarify if the PMCC was cold, the car's battery was cold, or both? I can't think of a reason why the PMCC being cold would interfere with it's functioning, however the car's battery doesn't like being charged when it's cold. It will first warm the battery then start charging. Maybe what you observed is normal behavior.

I would say that both were cold, I had the car disconnected during a couple of days, the temperature dropped and I connected the car for a planned journey the following day.
The problem as I see it is that the car would try to charge, but no charge was received, then stop and display a error message.

Hi, I am in Stockholm just now and experienced something similar. I was plugged in on a normal 220 volt socket so I would only get just over 2 kW. Same red light appeared but cleared after an hour or so. I was not using a PMCC but a Mercedes EVSE. I had set a minimum charge of 80% and nothing else. I think the battery was heated as a priority and once it was warm enough it started charging. It all worked out in the end for me. .

I am not sure how you used the PMCC? How many amps could you draw. Normal plug or 16 or 32 amp CEE plug? etc.

16 amps fuse on a single phase? If so that would give abort 3.5 kW. Most of that could go for heating the battery.

You will see a huge improvement when you have installed the 11 kW. Good luck
