Summary:PROBLEM TO BE SOLVED: To provide a controller with a battery diagnostic function capable of detecting abnormality of any battery in an uninterruptible power supply device in which a plurality of batteries are connected in parallel.SOLUTION: A controller with a battery diagnostic function of an uninterruptible power supply device comprises: one charger 10 connected to a commercial power supply for charging power; a charging/discharging control part 30 for controlling only one of a plurality of batteries 1 to 4 connected in parallel to be connected in a chargeable state from the charger 10, and for controlling at least one of the batteries other than the battery connected in a chargeable state to be connected in a state that power can be discharged to a discharger 20; and a battery diagnosis part for confirming a voltage rise and current fail of the battery connected in a chargeable state, and for confirming a voltage fall of the battery connected in a state that power can be discharged to the discharger to diagnose the presence/absence of abnormality and the type of abnormality as for each of those batteries.SELECTED DRAWING: Figure 3 【課題】複数のバッテリーが並列接続された無停電電源装置において、どのようなバッテリーの異常であっても検出できるバッテリー診断機能付きコントローラを提供する。【解決手段】無停電電源装置のバッテリー診断機能付きコントローラであって、商用電源と接続されて電力を充電する1台の充電器10と、並列接続された複数のバッテリー1〜4のうちの1つのみを充電器10から充電可能な状態に接続するとともに、充電可能な状態に接続されたバッテリー以外のバッテリーのうちの少なくとも1つを放電器20に電力を放電可能な状態に接続するよう制御する充放電制御部30と、充電可能な状態に接続されたバッテリーの電圧上昇と電流下降とを確認するとともに、放電器に電力を放電可能な状態に接続されたバッテリーの電圧下降を確認することにより、バッテリーそれぞれについて、異常の有無および異常の種類を診断するバッテリー診断部と、を備える。【選択図】図3
