Yes and no, during the cold snap I did plug the car in at night. Yesterday evening I went and picked up a pizza and rather than park under the carport (charger is under the carport) I parked in the driveway for an easier exit with pizza in hand, in any event I knew it was going to drop to 27F and left the car in the driveway overnight; according to the first sentence below that would seem to be OK according to the owners manual, but then the second sentence states 41F, in my mind anything between 15F and 95F is not extreme.
The owners manual is somewhat confusing, in the extreme weather we had last Friday (-2F) I drove to work in a car that was on the charger overnight, I consumed 8% (80% to 72%) the car was only going to be parked five hours; according to the owners manual should I have plugged in or not?
CAUTION: Do not expose your vehicle to extreme temperatures for long periods without driving or connecting to a charging cable, as this can negatively affect battery pack life. When temperatures are below 41°F (5°C) and you are not driving your car, connect to a charging cable.
