ChargePoint Flex Hardwire Issues

[GT_Taycan]

Hi everyone
New owner of CPO 2022 Taycan. Just got a ChargePoint home flex charging unit installed by electrician today, hardwired to a 60amp circuit. When I set the app up, I chose breaker amperage of 60 amps.

Went to charge the Taycan when electrician was still here and it started seemingly well, was drawing around 10.3kw so electrician left. Well as soon as he did the charging started stopping and starting again. The blinking green light on the Taycan charge port would turn flashing white, then minutes later go back to green.

Electrician can't come back until after Christmas due to staff being on holiday break (understandable). I am not sure if it's an issue with my car or the ChargePoint.

I tried both charging port sides on the Taycan and issue was present on both sides.

I also tried setting the ChargePoint amperage down to 50amp, and when I did the charging rate went down to 8.4kw but still had the same stop/start issues.
Here is a picture of what my ChargePoint experience is like so far.



I will try tomorrow to charge my car at a public station to see if my ports are ok (I just got the car 3 days ago and haven't driven much)



Has anyone experienced anything like this? I tried searching the forum but couldn't find anything like this .

Thanks

Were you using a timer/profile or was it direct charging ?

I just had my Chargepoint Hardwire wall charger put in this week. I've charged 4 times without any issues. Possibly an installation/connection issue?

No schedule being used, just straight direct charging (or at least I assume so! ... There is no schedule set in my ChargePoint app and there is no charging profile on my Taycan)

Stating the obvious of course but did you check and confirm that the electrician put the correct 60 A breaker in your panel? Just wondered if it was cyclic tripping or something similar although as I suggest this it seems improbable! Dodgy breaker maybe?

Did you call ChargePoint support also? They are quite good and may be able to determine if your unit is faulty.

If the Porsche is showing a white ring, IIRC that means it acknowledges being plugged in. So It would only stop charging if it thinks it has hit some max requirement. I'd make sure the "Direct Charge" button is on/illuminated on the lower interior display of the car before plugging in, and see if it successfully chargers to 100%

Overall this sounds to me like something funky on the car side, not wall side --

Try rebooting the ChargePoint unit from the app. If that doesn’t work, set up a timer program. I assume you downloaded the app? I’m not sure you wrote that you did. That’s critical for operating the ChargePoint charger. Everything is done from the app and it will also diagnose any problems. You may need to adjust the settings through the app. The charging station itself has no accessible controls. Good luck.

I have the exact same setup and only when I charge at off peak hours it would dip once but never stop. I always thought maybe the battery got too hot so charging back off a bit. But when charging direct it would stay on all the way. Maybe check the power rating of the cabling to the charger to see it can handle the load.

Looking at that graph two things come to mind. One is that the Ground Fault protection is tripping, because the "off" periods seem to be similar durations. The second would be overheat protection is causing it to stop cool off and start again. I'm discounting that second one a lot because you'd expect a long duration on period while it heated to overheat state, then a cooldown followed by shorter on durations because the EVSE is already warm.

Does the conduit leading into the charger get physically hot?

One interesting new thing I've seen my car do is that it's now breaking up charging during the charging window I've set in the profile. It used to start charging late in the charging window and charge continuously until it reached the target. Now, it seems to charge a bit during the entire 11 PM to 5 AM window until it reaches its target about 10 minutes before the end of the window. I had assumed that some software update had adjusted the charging behavior to be kinder to electric utilities by spreading out the load randomly. So that is similar to what I currently see but the off periods are much longer.

Replying to some questions above-

Yes I've downloaded the chargepoint app. No schedule set in it.

The conduit to the ChargePoint at home home does NOT get hot. Cool to touch. There is a slight vibration and high pitched sound coming from the conduit and where it meets the breaker. The unit itself does not get hot either. The cable gets mildly warm, barely warm.

I tried a public AC ChargePoint station. It charged at 5 kw. Worked flawlessly for 40 minutes. Then it stopped...but the ChargePoint station itself said "station offline" so I'm not sure the public station errored out, or if my car somehow caused it???


I then went to an EVgo fast charger to try DC charging and it would not start charging. Was getting concerned that it is my car that's the issue then but the gentleman next to me came over and asked me if my station wasn't working because his wasn't either. So maybe those stations were down too???

Called ChargePoint customer service and they ran through their standard troubleshooting. Rebooting, etc. Nothing worked. They are escalating for unit replacement.

Electrician will come Tuesday to look at the job.

Here is the last home charging session I tried with ChargePoint customer service helping me. At the end, it finally fully wiped out and gave me the "charging not possible" error message.

I'm assuming you don't have a receptacle at home that you can try charging with a mobile charger (PMC+ or equivalent)?
If it were me I would find some other public Level 2 stations (or a known reliable NEMA 14-50 receptacle) to try completing a couple of charging sessions successfully.
Based on what you have shared, the car has not been successful at any.

I don't have a NEMA 14-50 receptacle at home unfortunately.

I will try another level 2 public station soon, it's just so hard to find time with the holidays.

Fwiw, I did just charge at a EA fast charger...averaged 100kw and charged from 40% to 80% no problem. I think the AC and DC charging are separate things, so maybe this doesn't mean anything for my home charging issues (whether it's the car or the ChargePoint) but at least I have some sort of way to charge right now.

We have been using the chargepoint flex for 2 years. Early on we had an issue once that was fixed with rebooting the charger. I sounds like you have an issue with the charger, check the app and the logs to see if there's any errors. I would call chargepoint tech support, you may just have a DoA unit, but they can look from their side.

Final (hopefully) update:

Took car to dealer, they checked the charging ports and found no faults.

Electrician came and found no issues with the install. So, concluded that we must have just got unlucky and got a defective charge point unit.

Swapped the whole ChargePoint unit today for a new one, and so far my car has been charging for 2 hours with no issues. So, it seems it was just a defective unit that we got (from Amazon).
