Error during charging Message

The fan is a great idea. Try to have air flow over as much of the wire and handle as possible.

I am not sure if my experience will help, but here goes.

I normally charge at EA or on my home ChargePoint charger. Plenty of issues with EA, but those are not related to the issues described in this string.

Went to set up the Porsche Mobile Charger Connect so that I could take it on a trip with me. The unit kept faulting out after a few seconds when charging at 115 VAC 100% setting. This would seem to be too short a time for the unit to overheat. The charger was fine at 50%, so perhaps the unit detects a voltage drop when charging? Anyway, got a 12 AWG cordset (25 ft) and connected it to a 20A. 115 VAC receptable and now it would charge at the 100% setting.

Went on my trip and charged for 30 hours (!) on a 115 VAC outlet, 100% setting and never experienced a fault. Only got about 30 KWh, but that was enough to get me to the EA station when we retuned from our trip.

For me, the key was the heavy duty cordset. The Porsche Charger consistently faults out when using a lower gauge (14 AWG) extension cord, but the 14 AWG extension cord seems to work for everything else.

I figure you guys are plugged directly into an outlet, so this may not be your issue, but there is something that seems to trip My Porsche charger when connected to a higher resistance extension cord.

I have a vent fan in my garage that pulls air out of the garage and into the attic. In this TX heat, If I forget to turn it on when I charge, the rate drops dramatically. With the vent fan I can charge during the hottest part of the day without any issue if I need to.

About two days ago I started having this exact same problem. The car will charge a few percent, the charger appears to overheat (the cable is VERY hot), and the app says 'Charging Error'. I tried laying out the cable instead of coiling it; didn't help. I tried unplugging the evse, waiting, plugging it back in; didn't help. I just tried the suggestion from above to set the evse to 50% and that appears to be working; of course now the car is charging at half speed.

This is very annoying for a brand new car I picked up in late Jan 2022. I have an appointment for the software update in two weeks, I'm going to bring up the issue to them. Hopefully they've heard of the problem and can replace/fix the unit.

Welp, now that I'm back and relying on the Porsche Mobile Charger Plus again, it's failing again.

I'm going to try cutting to 50% power as a workaround until there's some kind of official fix for these things.

My charger wire and body runs about 125 degrees in my warm Florida garage. My dealer is looking into what can be done. My Audi etron charger has a thicker wire and runs 85F in the same garage.
Running @50% is a good work around.

I just don’t understand why it worked fine for ~ 1 year and is now overheating.

Me either. It was just as hot outside last summer and it worked fine.

My charger is starting to act up too. I’ve had two overnight charging sessions recently that did not complete within 7 hours (for less than 70% change in SOC). My charger received a software update on April 26. I wonder if that is the problem? My charger also worked perfectly last summer. And it isn’t even that hot here in Michigan.

I’m also getting charge errors more and more frequently, on an 18kW Wattzilla Wall Wattz. They started occasionally early this year and have been getting worse. It sometimes takes 3-4 attempts to charge the car to 85%. This EVSE has no option to adjust current (and the car of course doesn’t either…). Maybe if I kink the cable, it’ll slow down.

I have a 2020 and PMC was flawless as well until March 2022. Also live in FL with ventilated garage and hot summers. A few months ago my charger was failing at every point in charging (10-20%, 50-60%, and direct charge to 100%). Cord at the handle point was getting extremely hot. Documented all of it and sent to dealer. They said to throttle down to 20amps and that does seem to work. However, not a good long term solution. My dealer told me this is now a known issue across the board with PNA. I am working with them on some testing at the dealer and options to replace. Apparently they are replacing PMCs if you take your car in to have them validate it’s not the car. But it does not appear they have fixed the core problem. My dealer said several Taycans in our area are seeing the same thing. Maybe coincidence.

I have the Chargepoint Flex home charger, the wires run about 100F; The charger for my '21 Audi etron [looks the same as the Porsche unit] has thicker wire than the Porsche and runs around 100F as well. An agent at my P/dealer is looking into any fix. Otherwise they say run @50%.

What’s the temperature of the charger connect plus cable when it was charging your Taycan?

 

[Bill33525]

The 14-50 Plug on the Porsche Charger was 128F at the outlet.

Perhaps the Porsche ATI in this thread is relevant: https://www.taycanforum.com/forum/t...ature”-revised-may-13-2022.11575/#post-168914
