Abstract
A stationary electrical storage system includes: a stationary storage battery including nickel metal hydride secondary batteries; and a controller repeatedly carrying out charging with an external power supply and discharging to supply electric power to a load, stopping discharging to the load when an SOC of any secondary battery has become a first threshold, and stopping charging from the external power supply when an SOC of any secondary battery has become a second threshold. The controller additionally charges the whole stationary storage battery such that the secondary battery other than the secondary battery having the lowest SOC is allowed to be charged to a fully charged level beyond the second threshold by not stopping charging when the SOC of the any secondary battery has become the second threshold and the SOC of the secondary battery having the lowest SOC becomes higher than or equal to the second threshold.
