The present invention relates to a power control device (80) of a power apparatus (100) including a plurality of batteries (10,20) and a power generator (30) for charging the batteries (10,20) with electric power. The power control device (80) controls parallel connection of the batteries (10,20) and adjusts voltage by performing either a) a charging process for supplying electric power from the power generator (300) to a battery with the lowest output voltage among the batteries (10,20) or b) a discharging process for discharging electric power from a battery with the highest output voltage among the batteries (10,20) to a load circuit connected to the battery with the highest output voltage. The power control device performs a parallel connection if output voltage difference between the batteries is the same as a predetermined reference value or less.

    복수의 축전지(10, 20)와, 복수의 축전지(10, 20)에의 충전을 행하는 발전기(30)를 포함하는 전원 장치(100)에 있어서의 전원 제어 장치(80)이며, 상기 전원 제어 장치(80)는 상기 복수의 축전지(10, 20)의 병렬 접속을 제어하고, a) 복수의 축전지(10, 20) 중 가장 낮은 출력 전압의 축전지에 대한 발전기(30)로부터의 급전에 의한 충전 처리와, b) 복수의 축전지(10, 20) 중 가장 높은 출력 전압의 축전지로부터, 가장 높은 출력 전압의 축전지에 접속되는 부하 회로에의 방전 처리 중 어느 한쪽에 의한 전압 조정을 행한다. 복수의 축전지(10, 20)의 서로의 출력 전압의 차가 미리 정한 임계값 이하로 된 경우에, 병렬 접속을 행한다.
