Apparatus (102) for providing an operating energy (110) for an auxiliary drive (106) for an electric vehicle (100). The apparatus (102) has a battery interface (112) for connecting the apparatus (102) to a vehicle battery (104), a bidirectional inverter (114) having a first terminal for connecting the inverter (114) to the battery interface (112) and a second terminal. The inverter (114) is formed to convert a DC voltage into an AC voltage and back. A switch with a terminal which the switch to the second terminal, to an auxiliary interface (116) for connecting the apparatus (102) to the auxiliary drive (106) and to a charge interface (212) for feeding electrical energy (214) into the apparatus (102). The switch connects the charge interface to the switch and to the auxiliary interface (116). The apparatus (102) has a control device for providing the boost signal and the charge signal.
