Abstract
A method of determining the state of charge of a battery during charging may include providing a charging current having a first magnitude to the battery for charging, and changing a magnitude of the charging current from the first magnitude to a second magnitude. The second magnitude may be equal to the magnitude of current discharged from the battery during the charging. The method may also include determining a voltage across the battery after the changing, and determining a state of charge of the battery as a function of the determined voltage from a battery characterization curve.
