A method for operating a drive system () of an electric vehicle, comprising a first energy source (), a second energy source () formed as an electrical energy store, and at least one electric machine () is disclosed. In a first operating mode, electrical energy is transferred from the first energy source () to at least one electric machine (), and electrical energy is transferred from the second energy source () to at least one electric machine (). In a second operating mode, electrical energy is transferred from the first energy source () to at least one electric machine (), and electrical energy is transferred from at least one electric machine () to the second energy source ().

The invention relates to a method for operating a charging device for charging an electric energy storage device from a first charge state to a second charge state. The first charge state is lower than the second charge state, and the charging device is connected to an interface. The charging device communicates with the energy storage device and ascertains the charge state thereof. In an additional step, the charging device obtains the efficiency characteristic field of the electric energy storage device and the efficiency characteristic field of the charging device.
