Abstract
Disclosed are method and systems for determining the initial state of charge (iSoC) and current state of charge (SoC) for a cell comprising determining a plurality of cell parameters, including current (i), open circuit voltage (OCV), temperature (T) and time to maximum voltage threshold (tcv) of the cell, determining a plurality of cell iSoC parameters as a function of the plurality of cell parameters; determining an adjusted time to maximum voltage threshold (t′cv) of the cell: and determining a corrected iSoC parameter as a function of a predictor-corrector algorithm, the corrected iSoC parameter representing an estimated iSoC of said cell. Also disclosed are methods for determining optimum charge cycle(s) and parameters for the cell based on the corrected iSoC parameter.
