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.

That's it: Nio! Yeah, I dislike the reliability on the company, too.
Tesla did that as well about 10 years ago. They opted to not do it anymore if I recall correctly because they couldn’t control how the batteries were being maintained or what age of battery you would get.
