I left my car at DFW for three weeks. I left it at 70% but I turned off Sentry mode and overheat protection. I also didn't check in on my car very often, perhaps once a week. It was the first time ever leaving and I was concerned, but in the end I lost 1% of charge.
I wanted to leave Sentry on but decide I lived for decades without it. I also took my time and found a fairly safe spot to park where the lanes were wide and the change of door dings was not a concern.
I think this 1% loss over three weeks shows that the car never actively heats or cools the traction battery when not connected to shore power, even though the owners manual implies it does. All evidence points to traction battery heating/cooling only occurs (if required) when the owner preconditions the cabin while not connected to wall power. If anyone has proof of heating or cooling while parked and not connected to wall power, I have not found it.
