METHODS AND SYSTEMS FOR ESTIMATING BATTERY HEALTH

WIPO Patent Application WO/2012/166489

A3

A method of estimating a state of health of a battery (48) is disclosed. The method may include receiving information indicative of a history of electricity received by and discharged from the battery during a time period. The method may also include using the received information to estimate peaks in the electricity during the time period. Additionally, the method may include using an information processor (152) to determine a parameter indicative of an estimated state of health of the battery based at least in part on an estimated magnitude of electricity at each of a plurality of the estimated peaks.
