No, we're talking about batteries and charging. If you think battery tech is done evolving, wont shrink, and that "energy" and "power" are interchangeable concepts, then I don't think we can have a fruitful discussion.

That was my point. Saying something wont happen based on what's happened so far is foolish.

I think the point is that if battery technology is good enough, it's not the limiting factor. Being able to deliver that much power becomes a bottleneck. At some point the owner of the parking lot will have to upgrade their electrical service, which could be expensive.

I'm not sure how much of an issue that really is, though. Even if all cars are EVs, it's not like every single grocery store customer is going to fully charge their car every time they buy groceries.
