yet another reason why “EVs won’t save the world but rather save the dying auto industry”

Country needs to invest in supporting alternative transportation options across the nation. Cities need to be redesigned. The attitudes need to change. Car centric transportation doesn’t work at scale.

Yes, because combustion engines are also great at starting in freezing temperatures. If you manage to get it going, it's fine after a few minutes. But the cold start is a pain.

I think it depends on how cold is cold. They likely have different min temps before you start seeing issues.

Though engine block heaters are also standard in cars where it gets cold so at some temperatures this is a “nowhere to plug the car in” problem for both kinds.

A simple solution would be to warm the battery to a reasonable temperature but I don't know if that's feasible for such a large battery. It's not as easy as keeping a phone in an inside pocket vs an outside one. The car should be built with heaters around the battery. The power must come from the charger at charge time (but maybe the battery self warms itself while charging,) then from the battery. What's more: power…

All electric cars already do this, either with resistive heaters directly on the batteries or with water heaters in the coolant loop.

Presumably once going the internal losses keep it warm?

Modern cars have no trouble starting down to -20C. My 10 year old car was parked outside all of last winter and never had trouble starting even on the coldest days

90% of the complaints appear to be from folks who have no ability to charge at home. I would agree with the sentiment that if you have to drive any significant distance daily, and live in an apartment where you can’t charge at home, having an EV is going to be a giant pain and it might be a little too soon to go that route. I’d imagine we’re still several years away from having robust enough charging infrastructure a…

I'm confused that these people are confused. Why did they buy an EV if they don't have a place to charge it. It's like buying a surfboard while living in Iowa.

Well, there is a narrative out there that the ICE is dead and everyone should be driving electric. The media always neglects to add the caveat that the electric future has arrived only for garage-owning suburbanites.

A lot of them didn't buy them. There are a lot of Uber/Lyft drivers up there and many use the Hertz Uber rental program (https://www.uber.com/us/en/drive/vehicle-solutions/hertz/tes...). I'd guess that most of these would use superchargers as their idle lots to top up between rides.

I'd guess that this usually works pretty well, but with winter and a higher than normal number of broken chargers, those became more congested than normal, and this usage pattern will lead to it getting steadily worse throughout the day.

It seems like electric cars necessitate garages. Basically all these problems seem to be caused by people leaving them outside unplugged overnight, which I don't know how they deal with during the summer even. I can't imagine driving a car I have to stop for an hour to publicly charge every week. I guess it would be fine if you could charge it on the street or whatever, but you would still be using a lot of power jus…

this is basically what some cities try to enforce at the moment: everyone convert to electric, without enough garage places

Which cities?

Unless you have a weak battery, -10 isn't too cold for ICE cars. Even -20 is doable.
