1. An energy storage device comprising: a switching cabinet housing having reception spaces, wherein the reception spaces are configured to replaceably receive at least one control device and a variable number of storage blocks, wherein the storage blocks are selectively interconnected in series or in parallel and are connected to power connections via a current controller, wherein the current controller is configured to be scalable and operated in different scaling stages in dependence on the number of storage blocks and on the parallel and/or serial connection of the storage blocks, a detection device for the detection of the number of storage blocks used and/or of their parallel and/or serial connection, and a scaling device configured to automatically scale the current controller in dependence on a signal of the detection device.
