EV battery engineer here. It's not hard. Battery management systems are often over engineered but the state of the art is fairly straightforward and will allow battery packs of sufficient size last 200k miles or more easily.
I dunno the PhD electrochemist that I know who spent a long time teasing out the conditions and requirements for megapack operation didn't think it was trivial. That's also the reason Tesla pays Jeff Dahn so much money. A million miles/20k cycles is the goal.
