PROBLEM TO BE SOLVED: To secure, when supplying power to a plurality of devices, the power storage amount of a power storage facility in precaution against the peak time of power consumption in the plurality of devices.SOLUTION: A power management device according to the present invention comprises a control unit for controlling a plurality of devices receiving the distribution of total power supplied from a power storage device and another power source and a comparison unit for comparing the total value of a power consumption value consumed by the plurality of devices and a necessary power value needed for charging the power storage device and a supply power value from the other power source, control being exerted so that the power consumption amount of the plurality of devices is reduced until a total of the power consumption value consumed by the plurality of devices and the necessary power value needed for charging the power storage device drops to or below the power supply value of the other power source, and a charge to the power storage device is carried out. Furthermore, the power management device is provided with a comparison unit for comparing the power consumption value consumed by the plurality of devices and the power supply value from the other power source, control being exerted so that the power consumption amount of the plurality of devices is reduced so that the power consumption value consumed by the plurality of devices drops to or below the power supply value from the other power source, and a charge to the power storage device is carried out. |
