Abstract
The invention relates to an energy storage device and a method for operating an energy storage device comprising a plurality of energy storage modules. In order to adjust the output voltage to the energy storage device, one or more energy storage modules is/are connected in series. According to the invention, the series-connected energy storage modules are selected in accordance with the state of charge and at least one other operating parameter in order to be able to use the individual energy storage modules in a particularly efficient manner.
