POWER STORAGE AMOUNT CONTROL DEVICE AND POWER STORAGE AMOUNT CONTROL METHOD

A power storage amount control device includes a processor configured to acquire a value of a parameter representing a predicted power consumption amount of a load, set target power storage amounts of a plurality of power storage devices based on the value of the parameter representing the predicted power consumption amount, transmit a signal to the power storage device such that the power storage amount of the power storage device is equal to or larger than the set target power storage amount, and set the target power storage amount of a first power storage device supplying the power to a first load higher than the target power storage amount of a second power storage device supplying the power to a second load of which the predicted power consumption amount is smaller than that of the first load.
