PROBLEM TO BE SOLVED: To provide a power supply control device for controlling power supply from a plurality of power sources provided in a vehicle, in which a fuel amount consumed for power supply is reduced while restraining increase of a calculation load.SOLUTION: The vehicle is provided with the plurality of the power sources (a power generator 41, a waste heat power generator 25, a battery 43). In an energy device 51, by using a fuel amount Fi(Pi) consumed for supplying power Pi in the each power source i as a function of the power Pi, a fuel amount dF/dP for power increment is calculated, wherein the fuel amount dF/dP for the power increment is a differential value derived by differentiating the function of the power Pi with the power Pi. Distribution of the power supply from the each power source i is determined so that a sum of the power supplied from the plurality of the power sources can coincide with load required power Preq, and the fuel amount for the power increment of the each power source i can coincide with each other. |
