Abstract
Disclosed are an apparatus and method for estimating a state-of-charge of a zinc flow battery by measuring a concentration of zinc ions contained in an electrolyte through an open-circuit voltage (OCV). The apparatus according to embodiments of the present invention can estimate effectively the state-of-charge of the zinc flow battery from the concentration of zinc ions measured through the OCV of the working electrode with respect to the reference electrode when the measuring electrodes are installed in the cathode electrolyte tank or the anode electrolyte tank.
