In principle the idea is great. If we could agree on common standards and connectors for EV batteries, rather than charging at home you’d swing by an EV station and swap out your battery for a fully charged one. The idea was tested by Tesla in 2013 where they demonstrated swapping out a Model S battery in 90 seconds, and in California a company called Better Place actually launched a battery swapping service. Both have long been abandoned, however in China the idea is very much alive and even backed by the government.
