Estimating the State-of-Charge of All-Vanadium Redox Flow Battery using a Divided, Open-circuit Potentiometric Cell

In this paper, mathematical modelling of oxidation-reduction redox potential for estimating the state-ofcharge of V-RFB is presented. The estimation is based on the Nernst equation, a mass balance, Faraday’s law of electrolysis, and 1st order kinetic equation. The 25-100 cm2 laboratories, unit cell...
