Because it doesn’t solve the problem, it merely works around it. Solving the problem would mean coming up with a battery chemistry that doesn’t suffer in the cold. Instead the answer is “just don’t have it get cold”.

It’s not to say a hack/workaround isn’t useful, and I would say that it’s perfectly acceptable to simply use a battery heater in the winter. But calling it “solved” confuses solutions and workarounds, and that’s an intellectually dishonest thing to do.

From the perspective of the user, battery being cold does not matter. How it does not matter i dont care about, for user it is solved.

Now, we can go into the weeds as to what constitutes solved and we might agree or disagree.

It takes hours to heat a cold large pack til it's warm enough to charge. That's a drawback.

All the EV owners in Scandinavia don’t have practical problems charging in winter at will.

Also Scandinavia is not that cold. Their winters are quite warm, actually.

Leave your car with 5% SOC overnight and then try to find energy in morning to preheat battery. People have painted into corner themselves before. It’s perfectly adequate for my very mild climate and even then I get limited regen about 6 morning months per year.

This is the EV equivalent of riding your old motorcycle with the reserve valve open the entire time.

You are driving a giant killing machine around... it isn't too much to ask that you have some foresight to avoid the situation you describe.

Yet life happens and weather isn’t always exactly predictable. Why you against better batteries?

I'm not against better batteries. I'm against people who choose to operate with such a small safety factor for something as serious as operating a giant rolling 2 ton piece of metal and volatile chemistry. Just like I'm against people who don't know how to change a tire or properly drive with etiquette on the interstate; If you can't do it, you kind of deserve some teasing.

In my friend group, if you run out of gas you get made fun of. You forget to flip your kill switch and can't crank your motorcycle, we all laugh and call you a dipshit.

Getting stranded isn't always harmless, and proper adults don't get stranded. Proper adults manage their vehicle safely. That's my point. Yes, exceptions are allowed, but we need to make sure everyone knows they are exceptions. Don't leave 5% on your battery when in the freezing seasons, it's improper.

> I'm against people who don't know how to change a tire

TBH that's majority of people. And it's a good thing since tyres got so good.

I get it tho. It's obvious. But it's better when things work better.

It's not obvious because you're still making the excuses for baby-adults. No one is saying battery tech should stop being developed, nor should pain points be unaddressed.
