None of the ‘answers’ address the range issues with batteries in the cold. Or how you can be totally fucked if your pack drops below a certain temp, and you don’t have enough charge to heat the pack and get home.
Probably even more fucked than if your diesel tank gelled. At least you can heat it up directly if you really need to.
You handle it the exact same way you do on a gasoline vehicle. You never let your tank go below 50%. If you slide off the road with a low tank or a low battery you can get in trouble, so don't do that.
If I let my electric car sit overnight with at least 20% charge, I know it will start in the morning, even if it was -45 overnight. You can't say that with a gasoline vehicle. It'll take almost all of that 20% to get up to temperature, but once it's up it maintains it well.
And anyplace cold has ubiquitous block heater plugs. At really cold temperatures it'll barely charge on a block heater plug because it'll use all the energy keeping the battery warm, but it means you start with a warm battery and a warm car, so the range drop is massively reduced.
It’s delusional that you think you actually need to not go below half a tank (unlike electrical in the same situation), or that you can’t start a well maintained winterized vehicle at -48 cold (it’ll be hard on it, but it should still work) - as compared to an electric that flat out won’t work without heating the battery first. Especially gasoline powered.
EV’s at these temps are very problematic and much more likely to get you actually killed if something goes wrong, because of how they work. That’s just the truth.
Thinking that somehow it isn’t is the delusional part.
With enough care can you potentially avoid getting into a situation where you’ll actually get in deep trouble? I guess. But the margins are way thinner, and it requires a lot of range reduction, and your worst case scenarios are much more likely to happen.
