Beschreibung
Zusammenfassung:	An electric vehicle includes an electric drive device, first and second energy storage devices, and a bidirectional DC converter. The drive device, the DC converter, and the second energy storage device are connected to each other via a common intermediate circuit. The intermediate circuit includes an intermediate circuit voltage, the first energy storage device includes a storage voltage and is connected to the intermediate circuit via the DC converter. The drive device is supplied with drive energy by the first and/or second energy storage device. The intermediate circuit voltage is converted into the storage voltage in a first converter direction by the DC converter. The storage voltage is converted into the intermediate circuit voltage in a second converter direction by the DC converter. The first converter direction is activated when charging the second energy storage device and is deactivated when discharging the second energy storage device.
