摘要：

All-vanadium redox flow battery (VRFB) is one of rechargeable batteries. The battery can be charged and discharged by valence change of vanadium ions. The electrolytic solution of redox flow battery is circulated by pumps between battery cells and tanks. The characteristics of output voltage is influenced by chemical reaction, electrolytic solution flow, and electrical circuit. However, there is little research in consideration of the above interactions. Therefore, a model based on the above facts was established. Simulation results were compared with experimental results. The validity of the model was checked by comparison. Furthermore, simulation was performed to study the relation ship between charging/discharging currents and battery capacity. A peak of battery capacity was observed with change of current. The model was appropriate and simulation expressed the experimental result correctly. It is expected that this model will give a useful indicator to design and control of the battery. © All Rights Reserved.
