ELECTRIC ENERGY STORAGE AND A BATTERY MANAGEMENT SYSTEM USED THEREIN

摘要

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.

主权项

1. A battery management system comprising:
a terminal arrangement connectable to an electric energy storage having a plurality of energy storage blocks, the terminal arrangement being configured for exchanging electric energy between the electric energy storage and one or more external components; a switch assembly connected to the terminal arrangement and being connectable to each of the plurality of energy storage blocks, the switch assembly being configured to set an appropriate electric configuration of the energy storage blocks by means of a control signal so as to provide one or more rated voltages; and a controller configured to provide the control signal used for setting the electric configuration.
