Abstract
A redox battery energy storage system including multiple energy storage stacks having multiple reactor cells is disclosed. Each of the energy storage stacks may include an integrated DC/DC converter configured to convert an output voltage of the stacks to a higher output voltage. The output of the DC/DC converts may be coupled in parallel to an energy storage system output bus. By configuring the energy storage system in this manner, inefficiencies and losses caused by shunt electrical currents in the systems may be decreased.
Claims15
A redox battery energy storage system comprising:
- a plurality of redox battery energy storage stacks, each stack comprising a plurality of reactor cells;
- and
- a plurality of integrated DC/DC converters, wherein each DC/DC converter of the plurality of DC/DC converters is integrated with one of the stacks of the plurality of stacks and is configured to convert the output voltage of the one of the stacks to a higher output voltage at a converter output terminal,
- wherein the converter output terminals of each of the DC/DC converters are coupled in parallel to an output bus.
