摘要： Provided is an electric power supply system which includes a plurality of electric power sources and supplies electric power corresponding to demanded electric power. In supplying electric power to the outside from a vehicle which constitutes one of the electric power sources, the electric power supply system realizes generation of power by an engine at high efficiency while maintaining a balance between power income and expenditure. In supplying electric power from the vehicle, an amount of electric power generated by an engine mounted on the vehicle is decided based on information supplied from an external device such as transition over time in an amount of electric power demand including future prediction and transition over time in an amount of electric power which is suppliable from other electric power sources including future prediction.
