Abstract: The present invention relates to a supply cable (10) for electrically connecting a vehicle (12) both to an energy supply device (16) and to a consumer, comprising: —a connecting line (13) having a coupling (6); —a primary connector (14) which is electrically coupled to the connecting line (13) and which has a vehicle connection point (14A) for releasably electrically connecting to the vehicle (12); —a secondary connector (15A) which, depending on its type, is provided either for releasably electrically connecting to the energy supply device (16) or to the consumer; wherein the vehicle connection point (14A) has at least one transmission element by means of which a status line of the supply cable (10) can be connected to the vehicle (12), the status line being designed to have a first characteristic indicating readiness of the supply cable (10) to transmit electrical energy to the vehicle (12) and to have a second characteristic indicating readiness of the supply cable (10) to draw electrical energy from the v

Abstract: A charging cable for electrical connection of an energy store of a vehicle to an energy supply unit. The charging cable includes a charging line including a coupling and as multiple conductors electrically connected to the coupling, a first connection device including an energy transfer arrangement for electrical connection to the energy store, a second connection device including a first connection for electrical connection to the energy supply unit and including a second connection for detachable electrical connection to the coupling, respectively one electrical conductor of the charging line being assigned to at least a portion of the energy transfer arrangement of the first connection device, the first connection device including a control unit, the first connection device or the charging line including a bypass switch, the bypass switch being switchable between a first switching state and a second switching state based on a type of the second connection device.

Abstract: A quenching device is described that includes at least one chamber that can be filled with quenching gas and that has a blower wheel for circulating quenching gas, in particular a quenching chamber and/or a flow channel, a drive motor, situated outside the chamber, for driving the blower being allocated to the blower wheel. The drive motor is coupled to the blower wheel so as to transmit torque via a coupling that operates in contactless fashion. Also described is a related quenching method.
