Cabin pre-heating from battery instead of charger

[TomekGnomek]

Hi, we've had some low temps and snow in Poland.
I leave my car on the driveway connected to 11kw charger.
Noticed it prefers to cheat the cabin from battery instead of grid.

What I do:
- leave the car connected to the charger in the evening
- target SoC is set to 80% and overnight it reaches 80% (usually 81% od 82%)
- in the morning I use the app to pre heat the cabin (car still connected after charging)
- climate control works for 15-30 mins and the car is warm
- battery drops to 78% and it did no draw any power from the charger during this process

This seems like a bug or some bad design.
Did you noticed something similar?

I have noticed the same with my car. Makes zero sense. If the car is plugged in I would expect it to draw power from the charger and not the battery to pre-heat…

My iX3 does the same, perhaps the power used can only from the battery and not the charger direct.

My BMW does charge though during the heating/pre-conditioning.

You can switch DC Charging on to recharge the battery whilst the car is preconditioning.

Alternatively, you can temporarily increase the level of charge required in the My Porsche App to start charging the car remotely.

Same here (and it looks weird). Car connected to the grid BUT it uses battery to preheat the cabin….

is there a way to just change the SOC reach time of 80% to the time including the pre heating of the cabin. lets say you leave at 8am the heater kicks in 7:45 and the car is still in charge mode. drawing power from the batterie or grid would still allow for less or no loss of the 80%.
