Electric device power control optimized to device operational load state

An electric power control method for execution by an electric power control device connected via a control interface with an electronic device, to control electric power supplied from a power supply to, and consumed by the electronic device, the electric power control method comprising:

• a power consumption monitoring step of 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 step of calculating a moving average of the power consumption of the electronic device, based on the actual power consumption monitored in the power consumption monitoring step;
• a state-of-load determination step of determining state of the operational load on the electronic device, based on the moving average calculated in the moving average calculation step;
• a restriction period determination step of determining, according to a preset timing signal, whether the electronic device is operatig in a restriction period during which an upper limit in accordance with the state of load determined in the state-of-load determination step is imposed on the power supplied from the power supply to the electronic device, or in a restriction release period during which the upper limit is not imposed on the power supplied from the power supply to the electronic device;
• and
• an electronic device control step of controlling operation of the electronic device, according to the operational load state determined by the state-of-load determination section, by imposing the upper limit on the power supplied from the power supply to the electronic device when in the restriction period determination step the device is determined to be operating in the restriction period, and by not imposing the upper limit on the power supplied from the power supply to the electronic device when in the restriction period determination step the device is determined to be operating in the restriction release period.
