Zusammenfassung:	To provide a power system including multiple assembled batteries connected in parallel capable of accurately calculating the estimated value of SOC, for example, while charging all assembled batteries to full charge.SOLUTION: A power system P charges and discharges an external system. The power system P includes: a battery unit Bu including a battery pack 1 and a converter 2; and a control unit 3 that controls the battery unit Bu. Multiple battery units Bu are connected in parallel. The control unit 3 controls the converter 2 to charge the battery pack 1 until the same is fully charged after a specified time has passed since it was fully charged.SELECTED DRAWING: Figure 1 【課題】並列に接続された複数の組電池からなる電源システムにおいて、すべての組電池を満充電まで充電可能とし、たとえば、ＳＯＣの推定値を精度よく算出することを可能にする。【解決手段】電源システムＰは、外部システムとの間で充放電を行う電源システムである。電源システムＰは、バッテリパック１とコンバータ２とを含む電池ユニットＢｕと、電池ユニットＢｕを制御する制御装置３と、を備え、電池ユニットＢｕが複数並列に接続されている。制御装置３は、満充電になってから所定期間が経過したバッテリパック１を満充電まで充電するよう、コンバータ２を制御する。【選択図】図１
