Abstract

See full text

A number of illustrative variations may include a method, which may include obtaining terminal voltage data of a electrochemical device; determining an equivalent circuit model which operates in a manner approximating the terminal voltage data comprising an open circuit voltage VOC comprising a constant voltage source V0 and a voltage Vs across a capacitor Cs, in series with an overpotential circuit comprising an overpotential voltage V1; determining at least one of the power capabilities of the equivalent circuit model; and, estimating at least one of the power capabilities of the electrochemical device based upon the determined power capabilities of the equivalent circuit model.
