The main problems with electric cars are the autonomy and the recharge time, which makes recharge stations difficult to deploy. My entry is a station that removes the battery and replaces it with another that was previously charged on site. the process would be faster than a full recharge and could deployed on a wild scale. The car can be positioned with ground stoppers, and an industrial crane is precise enough to dock on the battery.

It would still need a standardization of battery and their position within the car, so at first it could be applied to rented urban cars, like the autolib program in France.
