To perform charge/discharge management of a plurality of secondary batteries efficiently in a short time. A power supply apparatus (10) has a plurality of secondary batteries (11, 12) connected in series, outputs a composite voltage of all of the secondary batteries, and outputs an output of a part of the secondary batteries as a partial voltage. The power supply apparatus includes a detecting unit (state detecting unit 17) that detects states of the secondary batteries and a changing unit (switches 13 to 16) that changes an order of series connection of the plurality of secondary batteries based on a detection result of the detecting unit in such a manner that the partial voltage is outputted from a secondary battery that is in a relatively good state.
