Can't DC charge

[LATE-CT]

So

Charged yesterday at a 50kW charger. Up to 98%.

Made an uneventful trip to Spain and back. Today I was at 50% so went for lunch to another city. Arrived there with about 25%. Had lunch then went to a store. Left with about 13%.

This is when my ordeal started.

I knew there was a 100kw charger at a local supermarket but that charger had given me trouble a few months back with a cryptic message "no slac message from car". I decided to try it anyway. Maybe they had fixed it.

When I arrived, there was a tesla charging. It was already at 65% so I decided to wait. The tesla owner appeared when he had 95% charge and left. I plugged in my car and, of course, I got the Slac message again. I tried 5 or 6 times to no avail. Eventually I gave up and decided to go to a 50kw charger that was nearby.

When we arrived, a EOS had just started to charge. I was now at 10% charge so decided to find another charger. There was a 60kw charger a few km away so headed that way.

We arrived there at 9% SoC, charger was free so I plugged in my car. The charge started for about 5 seconds and the charger disconnected with "charger error". I found that really odd. Tried another 2 or 3 times, same error.

I gave up but since I only had 9% battery, I moved the car to a slow 11kw AC charger that was right next to it. I used the left port of call this time and the charge started. OK. At least this works I thought. Waited a bit but at 11kw it was taking ages. Wife suggested to try another charger. I agreed. We left with 12%.

Arrived at another charger at about 11%. This 50kw charger was from a known supermarket chain which I use quite often. It was free so I plugged in... It's just to get disconnected again after 5 seconds. Tried a few times. Nothing. Now I was getting worried. I decided to connect the slow plug (11kw AC) and nothing. Same error on both ports.

Wife was getting upset so I decided to try another charger a few km more away. It was mentioned as being only 30 kW DC but I had no choice.

We arrived there with 10%. Plugged it in just to get another charging error. I started to think about tows. Wife asked if I couldn't reset the car like she saw me once doing it (Spotify was acting up so I rebooted the pcm at the time). I said that I didn't think a pcm reboot had anything to do with charging but I rebooted it. Had nothing to lose anyway. As soon as the pcm booted, I plugged in and behold... It's it started to charge! Of course to add to my bad luck, the charger only started to output 18kW... Better then nothing. I waited an hour until I got to 35% which would be enough to get home.

Two hours later I arrived near home. I decided to try at my local 50kw charger which I use once or twice per week. Plugged in and... Error again.

Tried 5 times and the charge wouldn't start. Eventually used the AC plug which started (on the right side port) and walked home.

So... Either all odds decided to go against me and all chargers just went blank on me today OR something is wrong with the car.

I don't really know what else I could try before giving up and just dropping the car at the dealership. I can't depend on AC only.

Anyone had a similar experience?

I had a lot of errors charging with DC and eventually my car wouldn't start one morning with an electrical fault..............Porsche have now had my car for 4 months, changed various things but now I believe they are changing complete new battery.

Ups...

I hope you get it fixed soon enough

Were all the chargers you tried 400V? Sounds like it as they are all under 100KW.

If there is a DC converter fault then hopefully an 80V charger will work? Just a theory

Could be indeed. Like I showed previously, the ecu did register a High voltage converter error.

For now it's still working. Fingers crossed ?

Too bad such a good driving car has many software faults still not fixed.
Woke up with airbag error few days ago out of nowhere, manage to erase it with carscanner app.
The most annoying thing is when it throws "key not detected" error every week and doors are not locking sometimes when I press the key buttons.

I don't think software can work around a weak/dying battery in the remote key fob.

I replaced the battery twice. I think its a cursed key fob because it allows me to get in the car then while driving key not detected shows up. I get out of the car try to lock it and buttons do nothing so I touch the door handles and works.

Still sounds like a weak battery to me - the car is pinging the fob constantly (you can hear some ticking in the center console area), and that may draw the battery below the threshold (and would explain why it's tired at 'locking' time). Try a different brand of battery, perhaps check the manufacturing date? ?‍
