Can we agree that what modern EVs do for battery management is very different to what early models did and that that has greatly improved battery longevity?

I think it's all called battery management. But early EV models did not have a whole lot of it. It obviously had some electronics to read out the current charge and put some basic limits in place. But no thermal management or cooling or any of the smart battery management features you see in more recent models.

You think it is called something, but state it with authority and ask for an apology when corrected. You should work on your communications skills.
