I find it strange that the charts only go down to 20°F, when for example at the moment I write this comment, it's -5°F (-21°C) in Bismarck, North Dakota. And sub-zero Fahrenheit temperatures are pretty common in the winter across the Northeast, especially at night. "Normal" driving conditions extend way below just 20°F.

Maybe there aren’t many people driving EVs there

Sounds like a lot of variance in experience, even in this thread. But if your car isn't breaking down, sounds like you should keep using it! But also be aware of inherent differences in battery performance in cold weather when recommending EVs to other Alaskans

We have a tiny electric fiat 500 for small distance trips. 21 kWh battery. My wife routinely gets 7 km/kWh out of it, I struggle to reach above 5.5 km/kWh. Driving style really matters. Especially with such a small battery ;)

The Germans would say that you have a heavy foot.

Well they're quite common in nordic countries; of course, the population of nordic countries tends to be in the southern latitudes.

I wonder though if there would have to be a balance, as you wouldn't want it to over-heat when charging during an Arizona summer.

Insulation also works to keep heat out.

Doing this in a passive way would put significant upper limits on charging speed. You'd have to combine insulation with some active way of getting rid of excess heat.

I make sure the displayed range on the M3 is double for the distance I want to travel. Winter tires, snow and ice sticking to the car, and -15C are quite normal occurrences here, and range display is pretty consistently half of what to expect.

Does the nav system do a good job of compensating? The "normal" display on the 3 is based on the EPA rating and is always wrong, but when I navigate, I find the trip range thing to be quite accurate -- even factoring in upcoming hills and traffic.

Keep in mind ICEs lose range in winter as well. I used to hypermile on occasion and I could get 500 miles on a tank in summer but 350-400 in winter.

The air is more dense, the tires are probably less efficient, the wind is stronger, and cold start efficiency is reduced.

How did they collect the data? It seems to be some kind of crowdsourcing. It's not possible to accurately determine range if they don't run them completely out of charge. It's doubtful that they got that many datapoints on every vehicle and every temperature.

While they aren't as popular in the Dakota's, there's quite a few EV's in Minnesota, where the temperature ranges are similar (1 degree Fahrenheit at the moment).

The Leaf has a bad reputation for this but this shows it’s toward the middle of the pack. I have one and this matches my experience.

Of course I have a 2022 and this looks at later models. Maybe older models were a lot worse. They’ve changed up the battery chemistry to be more tolerant of a wider temperature range I think.
