Abstract
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 Vcomprising a constant voltage source Vand a voltage Vacross a capacitor C, in series with an overpotential circuit comprising an overpotential voltage V; 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.
