The Faster, Cheaper, Better Way to Charge Electric Vehicles

WIRED 

Chinese carmaker NIO, the world's newest electric vehicle unicorn, has a big idea: battery swapping. In theory, the process is quicker and more convenient than a fast charge. A driver rolls into a battery swap station, and a robot replaces the drained battery with a fully charged spare. But even though NIO's battery swapping stations are already deployed in major cities across China, retail investors don't seem to be taking NIO's swap network seriously.
