Anecdotally last winter, had a Model Y up in maine for a trip home. I arrived at a backwoods house with ~60 miles left. It was around 10 farenheit the next day when I hooked up a 110 volt line to the car. Over the next 30 minutes the mileage dropped to 55 as it took more energy to heat the battery than the line could deliver.
I unhooked it and planned to drive 20 miles to the nearest charger, but after 1 mile of travel, it had dropped to 40 miles left. I turned around and drove back, now with ~20 miles left.
I parked the car in an unheated garage and plugged it back in, praying that the car would heat the garage to the point it could start charging. Maybe 2-3 hours later it started to take a charge, and 3 days later it was up to 150 miles, and I drove it to a super charger.
I realized after that, if I ever moved back to Maine and wanted a tesla I
- would need a heated garage
- I could never expect to leave my car overnight at a friends / trip during the winter.
