Abstract: The present invention provides a battery management system and an electric energy storage equipped with the battery management system, which enable the adjustment of one or more variable connection voltages. In particular the energy storage of the present invention may provide highly dynamic varying output voltages, for instance in the form of an AC voltage. In this way energy storages may, for instance, be directly operated in connection with an electric power grid or may establish electric AC power grids.
