A power source device is provided which can decrease voltage variation during switching between the power source parallel connection/power source serial connection with a simple configuration. It includes the power source body (40) including the first secondary battery (41) and the second secondary battery (42); power source connection status switching means for making switching among a power source parallel connection status, a power source serial connection status, and a single second power source status, an first inverter (10), an, inverter connection status switching means for making switching between a first connection status in which the power source body (40) and the first inverter (10) are connected and a second connection status in which the power source body in the single second power source status; When the power source parallel status is switched to the power source serial connection status, after switching to the first connection status, the first motor generator (110) is operated as a motor, switching is made to single second power source connection state, and the second connection status. The power source status switching means makes switching to a power source serial connection status after a serial connection status of the second secondary battery (42) to the first inverter (10) operating as a power source is made. |
