Abstract: A device for operating an electric auxiliary drive for an electric vehicle has a bidirectional inverter having a battery interface for electrically connecting to a vehicle battery and an auxiliary drive interface for electrically connecting to the auxiliary drive; a control arrangement having a first communications interface for connecting to the electric vehicle and a second communications interface for connecting to the auxiliary drive. The control arrangement inputs a configuration signal representing a present configuration of the electric vehicle and/or of the auxiliary drive via one of the communications interfaces. The control arrangement is formed to use the configuration signal to determine control parameters from a plurality of reference datasets with control parameters for different electric vehicles and different auxiliary drives, which control parameters are associated with respective configurations, and to control the inverter using the control parameters.
