Peak-shift method for notebook computers - a power management approach for load leveling

Electrical generating utilities are increasingly troubled by the growing gap between the peaks and valleys of electricity demand. This paper proposes a peak-shift method for notebook computers. This method is to enable a peak-shift on devices with built-in batteries such as notebook computers. Performing a peak-shift on such devices narrows the gap. In addition, it also helps reduce CO/sub 2/ emissions. IBM's ThinkPad notebook computers, as a real example, are introduced. Although the size of the peak-shift on each device is small, by combining large numbers of devices, it is possible to show large effects.
