Abstract
A method for estimating degradation of a rechargeable battery, includes determining a coulomb count value by integrating a charging/discharging current of the battery, monitoring a state of the battery, detecting that the battery is charged/discharged with a predetermined amount of charges, based on the coulomb count value, and changing an index X indicating degradation of the battery by a variation ΔX in accordance with the state of the battery, which is measured in a period during which the battery is charged/discharged with the predetermined amount of charges, if the charging/discharging of the battery with the predetermined amount of charges is detected.
