HYBRID VEHICLE WITH AN EXTERNAL ELECTRIC INTERFACE

The invention relates to a motor vehicle, preferably a utility vehicle, having a hybrid drive unit (11) connected to a traction energy network (7) of the motor vehicle; and an external interface device (3). The external interface device (3) comprises a bidirectional data interface for data exchange with an external device (2) and a high-voltage interface (5) for exchange of electrical energy with the external device (2), wherein the high-voltage interface (5) is connected to the traction energy network (7) of the motor vehicle (1). The motor vehicle furthermore comprises a control device (6) which is configured to receive identification data and/or operating data via the data interface (4) from the external device (2), which identification data and/or operating data characterize an electrical energy storage (14) and/or an electrically powered drive unit (15) of the external device (2), wherein the control device (6) is furthermore configured to control an energy transfer via the high-voltage interface (5) as a function of the received identification data and/or operating data and also to determine control data for the external device (2) and to send said control data to the external device (2) via the data interface (4).
