I kind of like what Nio is doing with batteries in their cars - quickly swap them out and be on your way instead of sitting there for an hour+ charging. It obviously wouldn't work everywhere as it requires a substantial infrastructure compared to a charging station (so economical in dense populated areas). But it's essentially as fast as filling up with regular gasoline. Pull in, battery gets swapped in minutes, pull out. BaaS (Batteries as a Service). It also lowers the price of the car up front since you don't pay for the massive battery, which is the largest cost portion of an electric vehicle.
