In these conditions, sometimes the temps fall even lower, and people will take their ICE batteries inside to prevent it dying. Can’t do that with an EV, and can’t leave it charged for two weeks. The EV I have in mind can run its own heater periodically to prevent damage. Could I count on it doing that for the entire vacation?
You need to get a neighbor to come over, stroke the hood gently, give it a cup of tea, and say nice things to your EV. Otherwise it will never forgive you for leaving it alone.
Seriously, there appears to be no limit to the overthinking people do about leaving a car alone. Two weeks is not a long time. 10 F is not an extreme temperature.
IIRC there were stories from a few years back that danced around this question. The one I’m thinking of is a guy who parked his car - a Bolt? - in the top covered corner of an airport garage. I want to say DTW, might have been MSP. He reported it was windy as well.
It was also at least a week so definitely cold soaked. IIRC he left home with a full charge, was at like 65-70% when he parked it. Getting back the car did start but was sluggish until it fully warmed up; took at least 10-15 minutes.
Personally I’d have AAA ready JIC, almost no matter what the car was. That’s just good risk management though, and not necessarily anything to do specifically with EVs.
People do not bring in car batteries at 10F. This is crazy person talk.
Nor do we being them in at -40. This is just silly talk. Sincerely, a Canadian.
10F, -12C that is not so cold at all. Are u Jamaican ? :) At-12c you don’t even have problem with winter diesel fuels With a ev I’ve no idea but if they have problem with that mild temperature I can’t see how it is possible to sell in Europe
I fly from Norway to France every Christmas for ca. 2 weeks, and always left my Zoé at the open air car park at the train station, where it experienced -20°C.
Never had any problems, maybe lose like 3% battery.
10F temperatures? Totally fine. I would start wondering if average daily low temperatures are -40F or lower
If you’re in such a cold place, how do you not have a block heater socket at the parking space?
Not to gatekeep cold, but block heaters aren’t a thing most people use when it only gets down to -12C. I grew up in a Labrador where they were heavily used, but nobody in Nova Scotia, where I moved to in my 20s, uses them.
Just charge it to 80 before you leave and don’t worry about it.
Charge it to 90% before you go and it’ll be fine.
I do this all the time
I leave my Tesla at the airport for a week in -20 Celsius
Just don’t have it on Sentry mode, which is the 24 / 7 surveillance mode you can put it on
It will be totally fine, but if it is easy I would plug it in. Even to 110 volt outlet would be fine. Nice to come back to a remotely started warmed charged car.
It’ll be fine. Depending on the power of your home charger it might struggle to charge at -10f, especially if it has an LFP battery pack, but just left out it will be fine. Make sure to turn sentry mode off.
It’s an EV, you just plug it in. It will be perfectly fine if you just leave it plugged in.
Left a Tesla sitting outside in Breckenridge for 3 days. The battery initially appeared to lose about 5% but recovered some when the pack warms up. Net loss was about 1% per day. Two weeks will be fine, at least with a Tesla.
And Teslas are notorious for high vampire drain so it will be even less of an issue on most other cars.
I had the 12v battery die in the winter after parked for 3 weeks unpluged. Regular battery had some ghosting loss.
