Abstract
An estimation method includes: performing, for each different degree of degradation, regression analysis between a first value and a second value, wherein the first value is related to one or more reference feature points on a differential curve of a charging-discharging curve indicating a voltage value with respect to integrated current amount of a reference storage battery, and the second value is at least one of a capacity value of the reference storage battery and an internal resistance value of the reference storage battery; and estimating at least one of a capacity value of a target storage battery and an internal resistance value of the target storage battery, based on a result of the regression analysis and a third value related to one or more target feature points on a differential curve of a charging-discharging curve of the target storage battery.
