This paper proposes an optimal charging method of a vanadium redox flow battery (VRB)-based energy storage system, which ensures the maximum harvesting of the free energy from RESs by maintaining safe operations of the battery.
At a constant electrolyte solution volume, increasing the vanadium ions concentration increases interconversion between VO 2+ and VO 2+ and between V 3+ and V 2+ at the positive and negative electrodes, respectively, which in turn leads to longer charge and discharge times. Fig. 5.
The high charging current causes a reduction in the crossover of vanadium ions because there is not enough time for more diffusion of vanadium ions. On the other hand, because of the high current, electrons transfer more quickly while there are not enough vanadium species to react with all the electrons.
In addition, the use of vanadium battery in applications with a relatively long cycle life and the highest coulombic efficiency is possible by applying equal charge and discharge current densities up to 100 mA cm −2.
Within energy storage technologies, vanadium redox flow batteries (VRFBs) are being widely investigated because of their advantages over other types of storage systems. This type of battery belongs to the family of redox flow batteries.
Increasing the vanadium ions concentration increased the charge and discharge times and increased the ohmic resistance and the faraday resistances, particularly the faraday resistance in the positive electrode. Increasing the electrolyte solution flow rate improved the discharge performance of the VRB. 4.
