Abstract: Disclosed are a redox flow battery system and a control method for the same. In the redox flow battery system, an oxidation number is controlled by injecting at least one of an oxidant and a reducer into at least one of a cathode side and an anode side using a measured oxidation number of the electrolyte. Therefore, even though an oxidation number balance is inevitably broken, since an initial concentration of vanadium ion, that is, an average oxidation number is maintained without a large change in the concentration, efficiency and stability of a battery may be promoted, and the oxidation number balance may be monitored in real time and the oxidation number balance may be recovered without a separate process of separating electrolytes to entirely mixing the electrolytes, or the like, that is, without stopping a function of the battery, thereby facilitating maintenance and control of performance of the battery.
