SYSTEMS AND METHODS FOR STATE OF CHARGE AND CAPACITY ESTIMATION OF A RECHARGEABLE BATTERY

A battery system may include a battery that in operation couples to an electrical system, and a battery control module that in operation electrically couples to the battery. The battery control module may read battery data, estimate a state of charge of the battery based at least in part on the batt...

Summary:A battery system may include a battery that in operation couples to an electrical system, and a battery control module that in operation electrically couples to the battery. The battery control module may read battery data, estimate a state of charge of the battery based at least in part on the battery data, and estimate a state of charge error of the battery based on magnitudes of state of charge error sources. Additionally, the battery control module may update a state of health estimation of the battery when the state of charge error of the battery exceeds a predetermined threshold.
