Charging speed issues at EA stations

[22gts]

As long as I can remember I've never been able to obtain the 270kwh charge speed. Looking for insight of what may be wrong or what to expect from porsche (have an appt for early December)

Had my 2022 Gts since March 2022. And nearly exclusivly charge at EA stations.

Many times my SOC is not low enough or battery not warm enough to get the 270kwh speed, however yesterday and today the car had ideal conditions, and max I was able to get was 152kw, then significantly slowing when i reach 50% charge.

This had me thinking that maybe 1 or 2 times I have ever gotten charge speeds over 150kw.

Yesterday, battery temp was 98 degrees and SOC was 15%. Plugged into a 350kw charger and it peaked at 147kw. Relativly maintained that charge speed until I hit about 50%, then it dropped to 100kw+/-. It remained at 100kw for the rest of the session (until 70%). During this time, I called EA and was told the charger was fully functional. I expected to get 270kw dropping to q50kw for this session.

Today, battery was 75 degrees, and SOC was 27%. At a different 350kw charger, I initially received 80kw, ramped up to 152kw (as battery warmed) and once I hit 50%, it dropped to 100kw+/-. Remained at that speed until I left, at 60% charge. Called EA after I left and they confirmed the charger I was at was fully functional.

There are alot of variables here and unsure what to expect from porsche when I bring It in for this complaint.

How would they test this? There is (1) 350kw charger within 40 miles of the dealer. And testing would require depelting the battery, hoping the charger is not out of service, and not in use.
Unless there is another way to test?

Any feedback of this concern would be great. Or any data I can provide to porsche when I bring the car in (in order to not waste my or their time) would also be helpful.

Most EA charging sites don’t have enough power available to hit those speeds. Doesn’t matter how perfectly ready your car is temp wise or SOC wise. If you get over 100, consider yourself lucky. It has nothing to do with your car.

Except when other cars are, it's not the charging station.

Person before me was getting over 200kw (ioniq 5).

This forum thread covers charging speed capabilities of the car.
But per post #2 above the issue is most likely EA sites limiting charging rates.
Take a look at PlugShare comments from users at the EA sites you used to see what charging rates they report.

Not that simple. Were there cars at the other chargers? The sites load balance.

What I can guarantee you is that the dealer will say that your car is fine.

I’ve never seen higher than 125kwh in 12k miles.

Yes.

The first example in my post, There were 4 chargers. 1 out of service.
3 other chargers were perpetually in use.
I was one of 4 people waiting to use them.

I was speaking to one of the owners of the charging cars' while I waited for a spot. They were getting over 200kw speed. Just so happened that I got the charger they were using, yet I couldn't get over 150kw, then a reduced 100kw.
All 3 working chargers were being used when they were charging and when I was charging.


The second example in my first post, I was one of 2 cars charging at the station. The other car left. After they left, I hit 50% SOC and my charge speed slowed. So it wasn't a overcapacity issue.
And the charger limitation also doesn't explain why my cars charge speed slows to only 150kw after I reach 50%.

All the replies in this are confirming my concern of , and kind of support my question of how can porsche test a car to confirm the car is not the issue of charging speeds?

I’d suggest reading all the other threads on here about charging speeds in the real world. There are a variety of factors that impact charging speed. But the fact is, in the real world, you will almost never see over 150kwh at an EA station. It’s not unique to your Taycan. I typically get 70-95.

All they will do is check to see if you have any codes indicating problems with your HV battery or onboard charger. If none, they’ll tell you the car is fine and that charging speed is dependent on many factors, etc.

Sad.

While I understand EA 's network is very flawed, if a car before me is pulling 200+, then my car is pulling only 150, and quickly falling off to 100 (well before porsche documentation says it should) when no other observational changes), its kind of unfair for them to wash their hands and place blame.

There is a big difference of no faults being shown and performing correctly.

Suprised they don't have a procedure in place to do a real world test without the "EA" variable.

This is exactly what they will tell you. Dealers rely on what piwis is telling them. You're unlikely to get anymore information.
