The invention relates to a method for operating an electric vehicle and to an electric vehicle. The electric vehicle comprises: an electric travel drive for a travel movement of the vehicle; a control device for controlling the traveling motion of the vehicle; a first energy storage device, in particular configured as a rechargeable battery device, for supplying a first DC voltage to the control device; a second energy storage device, which is designed in particular as a double-layer capacitor device, and/or which is charged and discharged in particular more quickly than the first energy storage device, for supplying a second DC voltage to the travel drive; the first energy storage device is connected, in particular electrically connected, to the second energy storage device via the conversion device, the first energy storage device is connected, in particular electrically connected, to the energy supply unit, in particular such that the DC output voltage substantially equals the first DC voltage, and the second energy storage device is connected, in particular electrically connected, to the energy supply unit, in particular such that the DC output voltage substantially equals the second DC voltage. The conversion device converts the first DC voltage into a second DC voltage, in which a power flow from the second energy storage device to the first energy storage device is blocked.
