Abstract: A storage system includes a storage battery, a first deriver, a second deriver, and a corrector. The storage battery performs charging and discharging of electricity. The first deriver derives a first state of charge (SOC) based on a voltage of the storage battery when a current is not flowing to the storage battery. The second deriver derives a second SOC based on a battery capacity of the storage battery and an integrated value of a current flowing to the storage battery. The corrector corrects the battery capacity of the storage battery which is used by the second deriver based on a difference between the second SOC derived by the second deriver and the first SOC derived by the first deriver after the derivation of the second SOC. Furthermore, the corrector changes a correction quantity of the correction in accordance with a state of the storage battery.
