ABSTRACT:
A power pack of batteries are enclosed in an encasement for protection and air-cooling. The encased batteries ride on wheels, and keep supplying power to an electric vehicle while attached to it. The unit can even generate additional electricity extending the driving range. When power is spent, run-down batteries are replaced by the wheeled unit with recharged ones, and the vehicle drivability is renewed on the spot.
