I saw a documentary about Renault doing this in Israel I think. With a network of stations looking like auto wash: it takes your car, opens a door under the car, swaps the battery with a full one and off you go.
Tesla had this exact functionality with their original Model S’ … but like that company it wasn’t profitable (or it was just regular ol Tesla mismanagement) so they also stopped doing it.
Not all EVs use the same pack type and there are advantages and disadvantages to the different types that will continue to change as we progress the technology. It wouldn’t make a lot of sense to have universal batteries as it would also limit the designs of the car if it were legislated.
Universal batteries would be bad, but standardized batteries would be great. If a battery has certain dimensions and gives a certain output, and can regulate itself as to charge and discharge, it doesn’t matter what chemistry it uses or internal cells it has. We have had D, C, B, A, AA, AAA, etc., for years and manufacturers got along just fine within those specs. Removable batteries are already a thing with Gogoro scooters in Taiwan and I think at least one car brand in China.
Those are cells not packs. A cell based pack uses cells in a module that then are combined to create a pack. Standardizing is not as easy as people make it out to be.
They can recycle 99% of the battery. You can crush it, separate and reuse. It’s actually pretty cool. Don’t know why you’d want to swap batteries that last for over 300,000 miles and soon to probably last longer than the car itself.

Apparently it went bankrupt after a year (2012-2013): https://en.wikipedia.org/wiki/Better_Place_(company)

How about a tow-behind battery for extra capacity?
It makes sense, but I already don’t trust anyone to tow anything safely.

I know a guy who started a company to do exactly this (in Europe only for now).
So the battery swap idea is out there, and being acted upon.
