Patent ID: 8433453

Claim:
A controller for leveling power supplied from a power source, comprising: a memory; and a processor, the processor configured to: acquire information of electric energy consumption from a power consuming device consuming electric energy from the power source and electric energy charged into a power storage device, the power consuming device arranged for a plurality of power storage devices charged by the power source; store a specific threshold value of electric energy for each power storage device in the memory; and control a first power consuming device to be power-supplied by the power source, the first power consuming device consuming electric energy lower than the specific threshold value of electric energy of the power consuming device, control the power storage device corresponding to the first power consuming device to be charged with a difference between the specific threshold value of electric energy and the electric energy consumption, control the power source to supply to a second power consuming device electric energy corresponding to the specific threshold value of electric energy, the second power consuming device consuming electric energy greater than the specific threshold value of electric energy of the power consuming device, and control the power storage device corresponding to the second power consuming device to discharge to the second power consuming device the difference between the electric energy consumption of the power consuming device and the specific threshold value of electric energy.
