<P>PROBLEM TO BE SOLVED: To provide a power supply system which smoothly accelerates a vehicle at the next start even when environmental factors are remarkably different between the current start and the next start. <P>SOLUTION: The power supply system includes: a fuel battery 1; a capacitor 2 connected to the fuel battery 1 in parallel; an electric motor 5 which is connected to the fuel battery 1 and the capacitor 2, for driving the vehicle; a secondary battery 6 connected to the electric motor 5 in parallel through a voltage conversion means 7; and a power supply control means 20 predicting transition of total output of the fuel battery 1, the capacitor 2 and the secondary battery 6, corresponding to the estimated environmental factor at the next start when the vehicle stops, and charging the capacitor 2 from the secondary battery 6 through the voltage conversion means 7 when estimated transition of total output does not satisfy a first requirement for maintaining stable acceleration performance of the vehicle by the electric motor 5 in a start-up period. <P>COPYRIGHT: (C)2010,JPO&INPIT |
