Abstract

In a method for operating an electric vehicle, including a first energy storage device (e.g., a rechargeable battery storage device), a second energy storage device (e.g., a double-layer capacitor device), an energy supply unit which provides energy, for charging the first and/or second energy storage device, and a first electrical consumer connected to the second energy storage device via an intermediate circuit, the first energy storage device is connected to the energy supply unit via a bidirectional converter unit, the second energy storage device is connected to the energy supply unit, a first power flows from the first energy storage device to the second energy storage device if an intermediate circuit voltage falls below a definable voltage, and a second power flow from the second to the first energy storage device is prevented.
