Hybrid vehicle having an external electrical interface

is connected, the invention relates to a motor vehicle, preferably commercial vehicle with a hybrid drive assembly (11) provided with a traction power network (7) of the motor vehicle; and an external interface means (3). The external interface means (3) comprises a bidirectional data interface for exchanging data with an external device (2) and a high voltage interface (5) for exchanging electric power with the external apparatus (2), wherein the high voltage interface (5) to the traction power network (7) the motor vehicle (1) is connected. The motor vehicle further includes a control means (6) is established, via the data interface (4) to receive identification data and / or operational data from the external device (2), the (an electrical energy store (14) and / or a powered drive unit 15 ) denote the external device (2), wherein the control means (6) is further adapted to control in response to the received identification data and / or operational data, both a transfer of energy via the high voltage interface (5) as well as control data for the external device (2) and to determine via the data interface to send (4) to the external device (2).
