PROBLEM TO BE SOLVED: To increase storage capacity that can be used in a power supply apparatus. SOLUTION: An alternator 16 is connected in series to a main battery 25 connected to an electrical component 23. A sub-battery 26 connected to the electrical component 23 is arranged in parallel to the main battery 25 and the alternator 16. The alternator 16 and the main battery 25 are connected in series, so that the main battery 25 can be discharged deeply without being restricted by low limit voltage of the sub-battery 26 and the electrical component 23. The storage capacity which the main battery 25 has can sufficiently be used, thereby increasing the storage capacity that can be used in the power supply apparatus 10. COPYRIGHT: (C)2011,JPO&INPIT
