    Is it true it draws power to keep the battery warm when parked, and if so is it significant?

      Some models do precondition the battery. Of those that do, if you leave the vehicle unattended for months you would notice the drain. Not over a few days though, the power drain is negligible compared to what’s needed to drive, or the increased range loss of a colder battery.

      To put things in perspective: The average consumer EV can drive for 3–4 hours, but can power an entire household (including appliances) for 2 days.

      I haven’t owned it through winter (no ID.7 owner has tbh) but I don’t expect that to be an issue. It will only heat the battery if you schedule departure times.

      I’ve noticed no battery drain with the car parked otherwise.

          Ahh then I might know where it comes from. People who use Tesla’s Sentry mode don’t realize that it uses up several percent per night. Now, it does turn off automatically when the battery is at 20% but I know people who parked at an airport and didn’t have charge enough to get home when they got back because of this.
