Electrical Circuit Model of a Vanadium Redox Flow Battery Using Extended Kalman Filter

This paper presents an equivalent electrical circuit model for a unit cell all-vanadium redox flow battery (V-RFB). The developed V-RFB model consists of an open-circuit cell potential (Ecell(ORP)) which is in series with an ohmic internal resistance and parallel with an n-Resistor–Capacitor (n-RC)...
