The present invention relates to a charging circuit for an electrical energy accumulator and a method for operating a charging circuit. Common components are used for charging and discharging the electrical energy accumulator. According to the invention, a charging circuit comprises step-up and step-down functionalities and combines them with rectifier and/or inverter functionalities. In this way, a circuit arrangement is created which allows a flexible circuit design with a small number of components.
