Abstract

The present invention relates to an energy storage device, comprising a switchgear cabinet housing in which a plurality of receiving spaces are provided, in which receiving spaces at least one control device and a variable number of electrical storage blocks are accommodated in an exchangeable manner, wherein the storage blocks can be selectively interconnected in series or in parallel and are connected to power connections by means of a current controller. Therefore, it is initially proposed to form the control device which is installed in the switchgear cabinet housing and the associated power electronics components themselves in a reconfigurable or variable manner in order to allow the controller and power electronics to be matched to another mode of operation or another application, without having to exchange the control and power electronics module and provide corresponding wiring for this purpose.
