<P>PROBLEM TO BE SOLVED: To avoid the drop of its supply efficiency as much as possible at the time of power supply to a driver for a mobile object, in a power supply system which is made by connecting a plurality of power feeders via power conversion equipment. <P>SOLUTION: This power supply system supplies power to the first driver and the second driver which function as drive sources for mobile objects. A fuel cell and a battery are connected via power conversion equipment. It can supply power to the first driver without using the power conversion equipment from the fuel cell and to the second driver without using the power conversion equipment from the battery. When the output request from the mobile object is a usual output request, the power supply to each driver is performed each by the fuel cell and the battery. Only when the power to be supplied to the first driver is over the power that the fuel cell can generate in the output request from the mobile object, the power supply from the battery to the first driver is permitted via the power conversion equipment. <P>COPYRIGHT: (C)2008,JPO&INPIT |
