<p><P>PROBLEM TO BE SOLVED: To provide a power supply apparatus for rapidly progressing charging/discharging between a high-capacity battery and a high-output battery connected, in parallel. <P>SOLUTION: The high-capacity battery 110 and the high-output battery 120 having an internal resistor and a capacity smaller than the high-capacity battery 110 are connected in parallel via a DC-DC converter 130 for receiving a voltage from the high-capacity battery 110, boosting the voltage and applying the boosted voltage to the high-output battery 120. A controller 140 is provided, and switches a voltage boosting state for boosting the voltage using the DC-DC converter 130 and a voltage boosting stopping state for stopping the voltage boosting and connecting the high-capacity battery 110 and the high-output battery 120, in parallel. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
