Abstract: A device for providing operating energy for an auxiliary drive for an electric vehicle. The device has a battery interface and an inverter, which is designed to convert, for a boost function, a direct voltage into an alternating voltage. The device also has a switch apparatus, which includes: —a switch terminal, which connects the switch apparatus to the inverter; —an auxiliary interface for connecting the device to the auxiliary drive; and —a charging interface for feeding electrical energy into the device. The switch apparatus is designed to connect the charging interface to the switch terminal and to the auxiliary interface by a switching signal.

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.

Abstract: A network of an electric vehicle has an energy supply interface, an inverter, an energization interface and a soft starter. The inverter has a first inverter connection configured to connect the inverter to the energy supply interface and a second inverter connection configured to connect the inverter to the energization interface and the soft starter. The inverter is configured to convert a DC voltage applied to the first inverter connection to an AC voltage and to supply same at the second inverter connection. The soft starter is configured to reduce an input voltage applied to the first soft starter connection and to supply the operating voltage, which is reduced compared to the input voltage, at the second soft starter connection.
