If you're setting a departure time in cold weather, it should take a lot longer than 20 minutes. I don't use them often, but last March mine took 1 hour and 18 minutes240, 40 amps. I have whole-house monitoring, and saw the full draw occurring. When I say it had no effect on range, I mean that a pretty low number was indicated as my range at 85%, and after preheating for 20 min, it still indicated the same range at 85% when I left.
