Abstract
A method of operating a redox flow battery string includes providing a plurality of redox flow batteries, each redox flow battery in electrical communication with at least one other redox flow battery, and each redox flow battery comprising an anolyte storage tank including a quantity of anolyte, a catholyte storage tank including a quantity of catholyte, and an electrochemical cell in fluid communication with the anolyte and catholyte storage tanks; obtaining an open circuit voltage value for each redox flow battery in the string; identifying a predetermined open circuit voltage value in the string; and adjusting the open circuit voltage value for each redox flow battery to correspond to the predetermined open circuit voltage value. A redox flow battery string system includes a plurality of redox flow batteries each redox flow battery in electrical communication with at least one other redox flow battery having an open circuit voltage value.
