Abstract

A power storage apparatus is disclosed, which includes a charge-able and discharge-able capacitor unit, discharged power being supplied to an electrical load. The power storage apparatus includes a detection unit configured to determine whether an amount of power stored by the capacitor unit falls less than a predetermined magnitude at a predetermined voltage. Degradation of the power storage apparatus is determined based on a detection result of the detection unit, and a setting value concerning charging and discharging is adjusted.
