Thank you kiev for your answers.
Today I had plenty of time to play with the OBDII device.
So I put the service-disconnect back to place.
only the P1A44 in the EV-ECU comes again.
All the other errors of the EV-ECU seemed to be old. I could clear them and they did not came back.
Actually I am at 67% SoC
I then concentrated on the P1A44. I cleared it and produced it again. Then I read out the fault code and the image of the EV-ECU values during the error (I think it is an image of the values when the error occurs, please correct if I am wrong).
Nearly all of the values were reasonable, but 2 of them were odd.
The Motor speed was reported with 9000 rpm and the speed with 153km/h. I was surprised that this car can ever go so fast
I was not able to clear this fault 39
I have not tried yet to charge the car again, because the plug in my garage is too weak and I have no access to the fuse.
I normally charge with that brick piece which came with the car.
I am going to try to charge again at another plug.
Yes, your are right. That is a logic explanation. So it should happen during regen while driving as well, correct? Or do I missunderstand?
Heater + AC:
As I got no faults from these devices and the P1A44 is coming out of the battery, I kept the devices plugged.
So for tomorrow I am going to give a charge to the car.

P1A44 BMU detected electric leakage (Ground Fault Current Detector in Pack?)

P1A2F BMU detected a Cell Error (need to read the BMU DTC for details)
39 Abnormal output voltage in the Power Factor Correction (PFC) circuit
How are you able to charge the car, Level (1 or 2 EVSSE), or DCQC Level 3?
When I brake with no regen (Mode Neutral) -> no issue
When I brake with regen (Mode Forward or Backward) -> issue
The Regen is trying to charge the Pack, so the electrical leakage or bad cell will be affected by this.
Actually I took out the Service-Disconnect to get rid of the heater and the AC, because I read a lot of trouble related to them. But the connectors seem to be accessed from below. I even don't know if it is ok to only unplug their high voltage connectors.
Shouldn't be a problem if the ends are sufficiently insulated from the chassis and each other to reduce High Voltage leakage currents.
