The present invention relates to charging an electrical energy store, in particular a traction battery of an electric vehicle, wherein the electrical energy store has a rated voltage which is higher than an electrical voltage provided for charging. For this purpose, one portion of the electrical energy store is directly charged by the electrical voltage provided, and a further portion of the electrical energy store is charged by means of an electrical voltage which is converted by a DC-DC converter from the voltage provided for charging. In this way, only some of the energy required for charging the electrical energy store has to be converted by means of a voltage converter.
