BATTERY STATE-OF-CHARGE CALIBRATION

A method of determining state-of-charge (SOC) of a battery includes changing the SOC of the battery over a portion of a full SOC range to assure operation defined by open circuit voltage (Voc) of the battery following a known Voc-SOC profile; determining a Voc value; and estimating SOC of the batter...

Zusammenfassung:	A method of determining state-of-charge (SOC) of a battery includes changing the SOC of the battery over a portion of a full SOC range to assure operation defined by open circuit voltage (Voc) of the battery following a known Voc-SOC profile; determining a Voc value; and estimating SOC of the battery based upon the Voc value and the known Voc-SOC profile.
