Error during charging Message

[W1NGE]

I am a relatively new Taycan 4S owner (3500 miles). So far, the car has been great with the exception of some of the known issues I have read about (back up camera, PCM wackiness, etc). I recently took the car on a round trip from Phoenix to Indian Wells, CA stopping for a charge at EA in Quartzite (which was totally seamless). When I got the car home last week, I plugged it in for charge overnight (Home profile to 85% at optimized charging). When I went to drive it on Tuesday morning, I got the following:

I thought it was just an anomaly, drove to work, spent lunch charging at the Wal Mart EA station with no issue other than the SOC when at 85% was about 180 miles (before the road trip it had been 200-ish miles). Plugged it in on Thursday using the same profile as mentioned above and got the following:

Did a little research and saw it was suggested to switch off optimized charging and move to a timed charge. Switched this in the existing profile, plugged it in and received yet another error message. I pressed Direct Charging in the car and it started charging with no error although I had to manage it up to 85%.

The other steps I have taken are to delete the profile, turn off and lock the car, wait 5 minutes, turn it back on and create a new profile - same charging error result. So, it charges on EA. It charges on Direct Charging, but throws off the error every time I try to use a profile at home. The dealer just wanted me to schedule an appointment (3 weeks from now). I wanted to see if anyone else had seen this error and if there was a fix

Profiles, timers and Direct Charging are only relevant for AC charging.

Could be heat issue, failing AC charger (charger is in the car and not the wall box) or earthing of your wall box.

Ensure no charging control is enabled in your wall box / EVSE to avoid conflict with the car controlling the charging session.

That is good to know, I appreciate the details. Obviously I'll be keeping an eye on this.

I think I might be in the "denial" phase

My charger is the plain one without the screen.

@JCW_DFW when you say it's the cord, do you mean the one to the NEMA plug, or the one to the car?

 

[DerekS]

Hate to say it, but good luck. I did a charge in Dallas last night from 25% up to 100%, in my 105 degree garage, using the new cord on the charging unit. If you get recurring error and have yours serviced at Park Place, Robert Salazar is the manager who knows exactly what to do about this. He's the guy who worked on getting my parts delivery down from 23 weeks to one week.

Yeah it's looking like a problem - I just got a charging error again and it's not even very warm out yet.

EDIT: False alarm, the app/web report charging error but the car is out there charging happily and the charger's web interface shows it continuing to dispense power.

They put a new cord that connects to the car on my Mobile Charger Connect unit. They might have replaced the NEMA cord too, but I don’t think so.

I just looked at my paperwork more closely, to answer your question. Turns out they also replaced the HV charger in the car, too. The service dept guys didn’t tell me about that. They described it to me as the wall unit’s cord.

Attached: First two pages are from the original work order, and show what they did on the HV charger on the car and reflect the need for the new wall unit cord. The third page shows the work they did to replace and test the cord. They did this with a separate work order, apparently. (The attachment order is random. Sorry for that.)

 

[DerekS]

Thanks @JCW_DFW for the details. I unfortunately had another failed overnight charge going from 50%.

I am hoping it does -not- require replacing the internal HV charger, but I have a way to rule it out. I will do a deep overnight charge using my wife's Tesla charger and TeslaTap. If that works fine and the Porsche charger continues to fail, I have my answer.

It's interesting that ours both started to fail after a year of uneventful use.

 

[JCW_DFW]

When he started looking for the parts, the Park Place guy said we're not the only ones having this problem with the wall unit cords overheating at about 12-18 months. I'm not convinced they really identified the problem as the internal charger, so much as they were throwing stuff at the wall to see if it worked. The charge after the internal "fix" was done on dealership equipment, not mine. It failed again when they tested on my charger. I had the same troubleshooting idea, but had no other household option. Good luck. It's a frustrating problem.

 

[DerekS]

I wonder if they can just replace the cord. The charger itself is unreasonably expensive, even my basic "charger plus" model.

 

[JCW_DFW]

That's all they did on mine. That, or they programmed the new one to have exactly the same settings and internet connections as the old one.

Unfortunately, they will make you leave the car there while they screw with it. That was the start of my saga -- I knew it was the charging unit, and wanted to just leave that with them to test, but in order to warranty it out, they had to test on the car itself. (Cynical me thinks it was also because they had five pages of recalls and software fixes to do, and once I showed-up for any kind of service, they were required to do all of those.)

 

[DerekS]

I have no idea which cord it is based on the docs - the NEMA side or the car side.
EDIT: I saw you said the car-side in one of your replies, thanks!

Suncoast sells the NEMA side for $120. If the car side is comparable I'm willing to just buy one rather than deal with the car in the shop for an indeterminate time.

It will hinge on my test with the Tesla charger of course.

Does anyone know if the Suncoast $120 wall-to-charger NEMA 14-50 plug is the one that resolves the overheating problem that we get with the factory NEMA 14-50 end of the cord that gets extremely hot (especially when in the charging dock), or is it the same one? I would buy it if it runs cooler so I don’t have to deal with Porsche service but don’t want to if it just will operate at the same hot temperature.

 

[JCW_DFW]

The one they replaced on my car is part number 7PP-971-676-BD. If you Google that number and "Porsche parts" you will find it from a couple places in the $600 range. I cannot tell from the graphic if it's the NEMA end or the car end. Drawing is short, so maybe NEMA, but the pricing does not foot to your quote.

Thanks. I believe based on Google searches that the part you cited is the cable that goes from the EVSE to the car with the J1772 connector. Agree the drawing is misleading.

 

[DerekS]

The whole issue is so bizarre. Why would a cable go bad in a year, or exhibit different heat characteristics? Especially in an enclosed environment not subject to the elements?

Is the thing melting on the inside? Or maybe it's not failing at all but a heat sensor in one of the business ends is?

 

[Klepper]

I have the exact same issue. I picked my car up on July 1, 2021, so almost exactly one year ago. I have had almost 17k miles of trouble free charging. I have not had a chance to take the car in yet, so I just set the EVSE on 50% and it charges fine. I need to get it fixed though.
