A redox flow battery, in particular a vanadium redox flow battery, with at least two functional units, for example at least two stages with at least one battery cascade, or at least two battery cascades, has a device for electrically decoupling at least one of these units. In order to ensure fault-free and functionally reliable operation of an energy supply system on the basis of such a redox flow battery alongside best-possible efficiency, a device for connecting a decoupled functional unit to at least one store for electrical energy is provided.
