Abstract: A method and apparatus for controlling operation of a redox flow battery. The method of controlling operation of a redox flow battery includes obtaining a diffusivity of anolyte ions with respect to a separator, obtaining a diffusivity of catholyte ions with respect to the separator, determining electrolyte diffusivities depending upon a state of charge value of the redox flow battery based on the diffusivity of the anolyte ions and the diffusivity of the catholyte ions, determining a minimum state of charge value and a maximum state of charge value of the redox flow battery based on the electrolyte diffusivities, and setting operating conditions of the redox flow battery based on the minimum state of charge value and the maximum state of charge value. The method and apparatus for controlling operation of a redox flow battery can prevent reduction in capacity of the redox flow battery.
