Preconditioning on full SoC drains the battery
I have an issue with my P400e. If I precondition the cabin while the car is connected to a charger and at 100% SoC the vehicle will fail to maintain the SoC and instead drains the battery. I can see the vehicle pulling 1-3 kW of power from the charger but that doesn’t seem to be enough.

Also, if I set a departure timer, preconditioning will fail if the vehicle is at 100% SoC, and show a message in the app saying that SoC is too low.

Anyone have similar experiences? My charger is 32A and typically outputs 7 kW when the car is charging.

I’ve only had mine nearly 2 months and haven’t preconditioned often. I do suspect that mine has also drained the battery even though it was on the charger at the time. I will have to test this to confirm.

I always charge to 100% and can confirm I’m able to successfully preconditioned when the battery is at 100%.

After a software update and reset of an associated module I can precondition of the charger power now too. Scheduled departures with timed climate still doesnt work though.

I worked out why this was doing it on mine.

My charger has a pre set charging window of 11:30pm to 5:30am when I have cheap rate electric.

When I was asking the car to precondition at 8am, even though the car was plugged in, the car could not pull anything from the charger as it was not in the charging window. So it would use the battery
