Patent ID: 8756443

Claim:
An electric power control device connected via a control interface with an electronic device, for controlling electric power supplied from a power supply to, and consumed by, the electronic device, the electric power control device comprising: a power consumption monitoring section for monitoring, via the control interface, the supply current and voltage of the electronic device, and from the monitored supply current and voltage calculating the actual electric power consumed by the electronic device; a moving average calculation section for calculating a moving average of the power consumption of the electronic device, based on the actual power consumption monitored by the power consumption monitoring section; a state-of-load determination section for determining state of the operational load on the electronic device, based on the moving average calculated by the moving average calculation section; and a control section configured to control, according to the operational load state determined by the state-of-load determination section, the electronic device to operate either in a restriction mode in which the control section imposes an upper limit on the power supplied from the power supply to the electronic device, or in a restriction release mode in which the control section releases imposition of the upper limit on the power supplied from the power supply to the electronic device.
