STORAGE BATTERY MANAGEMENT DEVICE AND METHOD FOR MANAGING STORAGE BATTERY

Abstract: a storage battery management device manages a storage battery having soc-ocv characteristics including a first region in which an ocv change rate is a predetermined value or less and a second region in which the ocv change rate exceeds the predetermined value. the device includes a coulomb counting processing unit that calculates capacity of the storage battery an soc estimation unit that estimates the soc of the storage battery, an ocv acquisition unit that acquires the ocv of the storage battery, and a correction unit that corrects the fcc of the storage battery used in the soc estimation unit based on the correction soc when a correction condition is satisfied that includes as a necessary condition that the correction soc is within the second region.
