Some Chinese start up is selling their cars w/o batteries and is setting up battery swap stations that can swap batteries in maybe 3 minutes. This is in only China I think. They standardize on BYD batteries and maybe another.

Nio is a Chinese electric vehicle maker who has taken a radical approach to selling EV's: sell cars without the battery, and allow their customers to swap for fully charged batteries whenever needed.
Nio has spent the past five years building a comprehensive, and expensive, network of battery swapping stations. Buyers of Nio vehicles lease the batteries, and instead of charging them they take them to a station where they are replaced.
This strategy allows Nio to sell at a price far below competitors. Swapping a battery takes only minutes, while charging requires hours.
Though it's early, customers thus far report a strong preference for the option of battery swapping, compared to fast charging. What's more, providing a fast and convenient charge positions Nio to directly challenge gas-driven cars.
Nio is partnered with BYD and CATL, the world's top producers of electric vehicle batteries. All three firms are now fully invested in the battery swap strategy, and believe that their sales growth is limited only by how quickly they can build more charging stations. And if they are correct, they will transform the transportation industry with little chance for rivals to catch up, for decades to come.
