Abstract: Briefly, embodiments of a system, method, and article for estimating a true state of charge (SOC) measurement for a battery based, at least in part, on a measurement of a rate of change of current supplied to the battery at a particular constant voltage value based, in part, on a current charging profile for the battery indicating a mapping between measurements of rates of change of current supplied to the battery at the particular constant voltage value and SOC measurements for the battery. A true SOC measurement for the battery may be determined based, at least in part, on the mapping. The first SOC measurement may be corrected to match the true SOC measurement at a particular point in time.
