However, you should always precondition the car, because then you waste less energy on heating/cooling after you plug it off.

So more charging power you got the better.

Ideally, you want the car cabin preconditioned and battery at 100% when you leave.
This is absolutely key. I am noticing in the winter temps here in the NE (in the 30s average right now) and parked on the street. If I don't precondition the car I lose about 30% of battery capacity compared to preconditioning first the driving off.

I haven't tested, but Tesla forums note you start to suffer once outside temps drop below the mid-50s.

If you have Level 2 I would make preconditioning a habit as much as possible.

BTW, what sort of time/consumption does the preconditioning phase take in winter time?
I try to give it 20 minutes. Not sure if it needs that much time, but that's worked for me so far.
