Abstract
A novel power supply control device includes an external power supply unit that generates external driving power from external power source, a storing power supplying unit that generates stored driving power from stored power source, a selection unit that selects either the external driving power or the stored driving power, a power mode switching unit that switches between a normal mode and an energy saving mode that consumes less power consumption than the normal mode, a determination unit that determines whether or not current time is within a peak power shift time zone in which usage of the external power is suppressed, and a controlling unit that instructs the selection unit to select the stored power as the driving power and instructs the power mode switching unit to switch power mode to the energy saving mode immediately after finishing an operation during the power peak shift time zone.
