摘要
A battery capacity estimation apparatus including: a battery; a sensing unit connected to the battery to measure an OCV of the battery; an SOC estimation unit connected to the sensing unit to estimate an SOC of the battery using the OCV measured from the sensing unit; a memory unit storing data including the SOC and the OCV of the battery, the memory unit being connected to the SOC estimation unit; and an operation unit connected to the SOC estimation unit and the memory unit, the operation unit being configured to calculate an SOC reduction degree according to a use voltage range change and re-calculate a changed SOC according to a changed use capacity.
