I'm really surprised the "balance" is so poor... My guess is that there's virtually no insulation and the manufacturers are skimping because it won't matter so much to the current buyers.
I think that is exactly it. Also, the big automakers have so little experience with EVs that they don't realize they need battery insulation. And, they don't tend to listen to advice from outside the company.
I've learned myself that even 1" of styrafoam insulation is enough to keep a half ton of batteries at 70 deg.F with just 100-200w of heat. A 30 KHW battery pack could supply 100w for almost 2 weeks! And if you leave the card plugged in, that 100w can come from the AC line; not the pack itself.
