The battery is probably the singular most expensive component in an EV Vehicle. And batteries degrade with time and are in different states. If someone comes in with a batter that's only half working, then swaps it for a fully working one? or One that comes to the station with a fully working one and swaps it for a half working one?

Batteries would need to be a communal resource - with them being expensive i don't see it happening. Batteries need to be cheap for companies and people to take the risk of swapping their battery with a random one.

What if you don't own the batteries, just buy the car without a battery and sign a contract for X years and $Y that you will get the battery replaced on each station?

People rent cars that are more expansive than batteries.

Obviously we should just swap the entire car. It would be like with horses, where you could swap for a fresh one to speed up a long ride.
