Abstract: A plurality of prongs of a connector box and a plurality of receptacles of a receptor box are electrically connected by mating each respectable pairs together. The boxes are coupled by a mechanical leveraged maneuver. The connecting device then connects vehicular circuits of an electric vehicle including those for auxiliary equipment to a battery-carrying trailer which is to be mechanically attached thereto and allows the electric vehicle to either extend its range, or be rescued from power shortage by electricity supplied by other than batteries onboard therein. The connecting device has a safety mechanism for preventing accidental separation of an electric connection, and for protecting operators from receiving electrical shock.

Abstract: A large number of vehicular batteries are charged while riding on gondolas, which go upon down and around in a space-saving tall tower. Charging electricity is distributed along the path of Gondola carriages. One or more recharged batteries are removed from the Gondolas which become ready to accept spent batteries, The gondola can be enlarged to accommodate even a battery-loaded vehicle.

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.
