PROBLEM TO BE SOLVED: To provide a power supply system which can stably continue power supply to a variety of electrical loads.SOLUTION: A power supply system mounted to a vehicle having a rotating machine 10 which starts an engine by being driven by power supply comprises: a lead accumulator 11 and a lithium ion accumulator 12 which are connected to the rotating machine 10 in parallel therewith; a MOS switch 15 which is connected between the lead accumulator 11 and the lithium ion accumulator 12 in a first connecting passage 21 for electrically connecting the lead accumulator 11 and the lithium ion accumulator 12; electrical loads 14a to 14c which are connected to the lead accumulator 11 side out of the lead accumulator 11 side and the lithium ion accumulator 12 with the MOS switch 15 sandwiched therebetween in the first connecting passage 21; and a control part 20 which holds the MOS switch 15 in a closed state other than a start of an engine by a generator 10 after the powering-on of the power supply of the vehicle.SELECTED DRAWING: Figure 1 |
