There actually was a Chinese EV startup that had battery swap stations: drive up onto the system, and the battery is directly under your car; the swap takes <1 minute. I don't remember what it was called, though, nor if it ever made it.

Tom Scott did a video on it. In all honesty, there are a number of things about this system that I just don’t see working well in the long term, but it’s an interesting prototype nonetheless.
