Does the heater handle real winters, like they have in Alaska, Mongolia, and parts of Russia north of it? Or just European and American "winters" where -20°C is considered hardcore? Gasoline powered engines handle this well, and you can warm them up with a gasoline torch if they stay outside for too long and refuse to start. The cold does not destroy them. | |||||||||||||||||||||||||||||||||||||||||||||||

I don't see why a built-in heater is worse than aiming a torch at a car to get it to start. Seems like a major oversight for gasoline cars. Also, a tiny fraction of the population will ever need to start their cars in Alaska, Mongolia, and Northern Russia. The small city worth of people living in these insane environments can stick to their wood-fueled diesel cars while the rest of the world just uses normal vehicles. | |||||||||||||||||||||||||||||||||||||||||||||||

It handles "real winters" [1] where large portions of the human population live.

Alaska, Mongolia and Russia are extreme edge cases that I don’t believe hold much weight in an argument. It’s like those arguments where folks try to attack solar or wind, “solar won’t work on northern Alaskan winter”. Ok great that’s such a small slice of the population that it’s ok. | |||||||||||||||||||||||||||||||||||||||||||||||

Are you a car ad where you're selling the most extreme off-road experience for the person who just wants to go to the grocery store? Come on man. If you're in an extreme environment, get the tool appropriate for that environment. People in mountain environments tend to have 4WD or AWD cars because it's appropriate. Doesn't mean a non-AWD car is useless. If you live in the extreme 5%, get something that works there. If you're in the rest of the 95%, other solutions work fine. | |||||||||||||||||||||||||||||||||||||||||||||||

Those are quite niche environments. The success of LFP won't hinge on whether it works below -20C, obviously. | |||||||||||||||||||||||||||||||||||||||||||||||

You can discharge the battery to power the heaters, at significant cost in energy. The temperature becomes a serious problem when charging (will physically destroy the battery through dentrite formation!), and under very high power draws (battery can’t keep up chemically). It can be solved, but at a cost, and makes the tech much more dangerous - you could end up in a situation where you freeze to death somewhere more easily in the climates it is a problem. It’s similar reasons why diesel isn’t a great idea in Alaska and the like too, and people tend towards gasoline even in situations where it is more costly and less efficient (like industrial trucks). It can be mitigated with chemical additives (‘heat’), tank and block heaters, etc. but has similar risks. | |||||||||||||||||||||||||||||||||||||||||||||||
