Abstract

　電源セルの異常な電圧低下を検知するとともに、この電圧低下が復旧している場合には発電を再開させ合理的で安定的な電力供給を実現し得る電源装置を提供する。 　複数の電源セルを電気的に独立させて構成した組電源と、電源セルの端子間を切換素子で選択的に接続することにより各電源セルを任意に接続する切換器と、電源セルの端子間の電位差をそれぞれ検出する電圧検出器と、電圧検出器が検出した前記電位差をそれぞれ表わす電圧信号に基づき電源セルの発電電圧が設定電圧以下になった場合には当該電源セルを切り離して電力の供給を休止させるとともに、切り離された電源セルにおける休止時間が所定時間以上となった場合に電力の供給を休止させていた電源セルからの電力の供給を再開させるように制御信号で切換器を制御して切換素子のＯＮ／ＯＦＦ状態を制御する制御器とを有する。
