Energy storage arrangement, energy storage system and method for operating an energy storage arrangement

摘要

An energy storage arrangement or configuration includes an energy store or storage device which can be connected to an electrical energy supply via a buck converter and a choke device. A boost converter is connected parallel with the energy store and the buck converter. The energy store is configured to be charged to a higher voltage level than the voltage level of the electrical energy supply. An energy storage system having multiple energy storage configurations and a method for operating an energy storage configuration are also provided.
