Abstract

A battery system for electric vehicles in which replenishment of the energy content of the batteries is accomplished by pumping liquids into tanks on the vehicles from pumps at service stations, similar to, and in a comparable time to, the filling of the tanks of conventional vehicles. The system also extracts used liquids, which have been depleted of energy content, from the vehicles and returns them to the service station where they are recharged for subsequent supply to other vehicles.

Claims

1. A rechargeable electric storage battery which is recharged by the exchange of liquid electrolytes with any of a plurality of separate and distinct charging batteries, said separate and distinct charging batteries being recharged by the passage of an electric current.
