The power storage system is a system including a power storage device provided in a facility such as a house that is supplied with purchased power from a power system such as a power grid, a power demand device (an air conditioner, a heat pump water heater, a charging/discharging device, an electrified vehicle) that is different from the power storage device, and HEMS controllers that manage the use of power in the power storage device and the power demand device. HEMS controllers comprise a processor, such as a CPU of controls. The processor controls the power storage device to charge the power storage device when the remaining capacity stored in the power storage device is equal to or less than a predetermined value after limiting the use of the purchased power in the demand device.
