You might “buy” more things if you actually continue reading rather than instantly feeling the need to stop and respond to a post?
But to address a few of your expansions on what I said immediately after you just HAD TO CORRECT SOMEONE!!!
- People don’t drive around in freezing cold cars: It matters less what the temperature in the cabin is and more what the temperature on the battery itself is. Most designs try to consolidate both to a degree but, for safety and insulation reasons, you are going to have a difference
- Cars are heated and it doesn’t use much energy: That is only if you have a heat pump rather than resistive heating. Most of the mid/upper tier (e.g. ioniq5) provide these, but not all do. And, if it is snowing and raining hard, you will start to run into the limitations of a heat pump. At which point you are either SOL or back to resistive heating
- If your EV is plugged in overnight: That is one of the ongoing issues with EVs where the vast majority of apartment complexes and hotels don’t have chargers
- EV batteries and motors generate heat when they are running: To nowhere near the same degree as a combustion engine
And then you just reiterated exactly what I said after you cut off the quote, regarding different brands and models having different behavior.

If the cabin is warm and the battery is cold, somehow exchange heat between the two. Not hard.
Every car has a heat pump - it’s more commonly called air conditioning, but it’s the same thing. And while some are only capable of cooling the ones that can do both cooling and heating cost basically the same to manufacture.
Cars don’t use resistive heating - they commonly draw on heat from the combustion engine… in an EV that doesn’t generate enough heat (unless you’re on a race track) so you’d use a heat pump. Simples.
That’s relatively easy to fix though. Chargers don’t cost much to install, get it done in your own home (even if it’s just 110v - more than enough to keep the batteries warm) and you should be able to find hotels that have them (though seriously, how often are you staying in hotels and driving your own car? that’s a bit of a niche…)
I read the rest of your comment. I agree with the facts you wrote but what I don’t agree with is your interpretation of them. A car that has 35% less than the advertised range for several months of the year does not meet customer expectations and should be either fixed with a recall or customers given a refund.

All telsa had to do is complie with current standards which is to list highway and local mpg equivalent.
Chevy doesn’t list a cold range when I need to idle the engine to get it warm enough to drive on a standard car.
