    摘要: Systems and methods are provided for rebalancing cells in a redox flow battery. In one example, a method of operating a rebalancing cell in a redox flow battery system includes measuring a state-of-charge (SOC) of a redox flow battery in the redox flow battery system, calculating an electrolyte concentration from the measured SOC of the redox flow battery, and maintaining a rebalancing reaction rate at the rebalancing cell. In one example, maintaining the rebalancing includes, responsive to a change in the electrolyte concentration, adjusting an electrolyte flow rate to the rebalancing cell and adjusting a hydrogen flow rate to the rebalancing cell.
