  • Patent number: 8041522
    Abstract: A system and method for determining an estimated battery cell total capacity indicative of a total capacity of a battery cell is provided. The method includes receiving a first battery cell state-of-charge estimate at a first time and receiving a second battery cell state-of-charge estimate at a second time subsequent to the first time, measuring an integrated battery cell current value indicative of the integrated battery cell current between the first time and the second time, updating at least one recursive parameter based on the first battery cell state-of-charge estimate, the second battery cell state-of-charge estimate, and the integrated battery cell current value, determining the estimated battery cell total capacity based on at least one recursive parameter, and storing a value corresponding to the estimated battery cell total capacity in a memory.
