Abstract
Specified is an arrangement for supplying power to a motor vehicle which is equipped with an electric motor and in which there is arranged at least one rechargeable electric battery to which the electric motor is connected. The arrangement includes a stationary charging station which is equipped with an electric power source and to which an electric line having at least two mutually insulated electrical conductors is connected, a part of an electrical coupling for connecting to a complementary coupling part present on or in the motor vehicle being attached to the free ends of said electrical conductors, said coupling part being connected to the battery in an electrically conductive manner. The electric line is surrounded along its entire axial length by a thermally insulated and flexible tube made of metal which is closed all around and which, in addition to the line, encloses a cavity along its entire axial length. A flowable medium refrigerated to a temperature of at least −160° C. is contained in the space enclosed by the tube, and a thermally insulated storage tank containing a store of the refrigerated medium is arranged in the charging station, the tube being connected to sai…
