摘要： In a method for operating an electric vehicle, including an electrical drive device for driving the vehicle, a control device for controlling the driving of the vehicle, a first energy storage device for supplying the control device with a first DC voltage, a second energy storage device for supplying the drive device with a second DC voltage, and an energy supply unit providing an output DC voltage, the first energy storage device is connected to the energy supply unit via a converter device, the second energy storage device is connected to the energy supply unit, the converter device converts the output DC voltage into the first DC voltage, a first power flow from the first energy storage device to the second energy storage device is prevented and a second power flow from the second energy storage device to the first energy storage device is prevented.
