Abstract: An electronic apparatus (200) comprises processors (20)-(22), devices (30)-(33), and a peak power-managing unit (10). The peak power-managing unit (10) includes a power information storage unit (11) operable to store a total power consumption value, and a suspended request storage unit (12) operable to store suspended use requests. Each of the processors (20)-(22) addresses, to the peak power-managing unit (10), a use request for the use of a target device among the devices (30)-(33). The peak power-managing unit (10) issues a device use permit notification to the processor when determining that the operation of the target device still maintains an added total power consumption value within a specified value. Upon receipt of the device use permit notification, the processor sets up a course of action to be provided by the target device. As a result, controlled peak power is provided, and the devices can be run according to updated information.

Abstract: A peak power-controlling apparatus including a generating unit (3) operable to generate at least one activating combination available within a predetermined period of time to activate a plurality of devices (6) to (8), each of which has an activating period and required electrical power, in which the activating period includes an operative period of time and an inoperative period of time, a calculating unit (4) operable to calculate a total power consumption value for each of the at least one activating combination, thereby providing the calculated total power consumption value, and a selecting unit (5) operable to select, as a selection result (12), one of the at least one activating combination based on the calculated total power consumption value. As a result, the peak power-controlling apparatus can suppress peak power of the plurality of devices that includes periodically operated devices.
