Abstract

An electrically powered steerable vehicle usable by the physically challenged has at least one rechargeable battery system, a shopping basket at its front end, and a probe electrical terminal mechanism connected with said battery system and adapted to be carried forwardly on the shopping basket which is connectable with a probe receiver assembly mounting a charging station. Electrical connections are adapted to be attached between the probe receiver, charging station, and a source of electrical power. The probe receiver comprises a forwardly converging system including at least one electrically conductive, resilient, laterally expandable part adapted to be supported at the level of the probe electrical terminal mechanism.
