I'm on a time of use electric plan at home. My teslas are scheduled to finish charging by 5 am when super offpeak pricing ends. If i want to run the kids to school at 8 AM in the winter i want to defrost my car a few minutes before we leave, but when i do the car starts charging again. My electricity is expensive at 7:50 AM. Is there any way to defrost without drawing power from the grid without walking outside and unplugging?
