I live in Toledo, OH, where it has been pretty cold. I drive about 25 miles a day and set my charger to "trickle feed" the battery overnight. By the time I wake up, the battery is charged and the car is off, and no longer charging. Although I have a semi-heated garage, the interior of my Model S P usually reads in the low 50 degrees when I get ready to condition it in the morning prior to going to work.
Here's the issue I have, and one I think can be corrected pretty easily via software:
When I start conditioning my car via my mobile app, the car draws power from the battery, even though it is plugged into the wall! I believe that this occurs because the car is in the "off" mode after the battery has fully charged. It would make more sense that when I start the conditioning process with the car plugged in, that the car should recognize it is plugged in, and subsequently "turn on" and draw power from the grid and not the battery.
Let me know if you all have been having the same experience and whether or not this update would be helpful for you as well.
