description Charging stations are used for charging electric storages of electric powered vehicles. In order to increase flexibility of such charging stations the invention proposed charging stations which comprise an input circuit (3) for connecting the charging station (1) to an electrical power source and providing a first intermediate DC voltage (DC1) at a first DC output at a first DC voltage level; at least one DC/DC converter (4) which receives the first intermediate DC voltage (DC1) and which provides at a DC/DC converter output a second DC voltage (DC2) at a second DC voltage level; an electrical DC charging buffer (60) connected to the DC/DC converter (4); and an output circuit (7) for converting the second intermediate DC voltage (DC2) to the DC current or AC current requested by the electric vehicles (9). A control circuit (41) which is adapted to measure an output current provided by the at least one of the DC/DC converter (4) determines on basis of the measured output current a power control signal for controlling the power consumed by the input circuit (3).
