Abstract
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.
Claims5
A redox flow battery which comprises:
- first and second functional units for storing electrical energy,
- a first electrical circuit for connecting said first and second functional units in parallel to a load,
- a first switch means in said first electrical circuit for disconnecting only said first functional unit from the load, and
- a second electrical circuit for electrically connecting said first functional unit with said second functional unit, said second electrical circuit including only a DC/DC converter and second switch means for electrically connecting said first functional unit with said second functional unit when said first functional unit is decoupled from the load and enable electrical discharge of said first functional unit to said second functional unit.
