PROBLEM TO BE SOLVED: To enable appropriate landing operation on the nearest floor during a power failure even though a battery for an elevator power failure deteriorates.SOLUTION: In a system including a plurality of elevator cars and a battery for a power failure in each of the elevator cars, a battery capacity to be required for landing operation on the nearest floor during a power failure of an elevator car is calculated from a car position and load information when the power failure is detected. Then, the battery of each elevator car is switched to a driving power supply of the elevator car with a battery connected thereto, wherein deterioration or charging capacity shortage is detected by a command generated on the basis of the calculated result.SELECTED DRAWING: Figure 7

    【課題】エレベーターの停電用のバッテリーが劣化しても、適切な停電時の最寄階の着床運転が行えるようにする。【解決手段】複数台のエレベーターかごと、それぞれのエレベーターかご毎に停電用のバッテリーを備えたシステムにおいて、停電を検出した際に、かご位置及び負荷情報から、エレベーターかごの停電時最寄階着床運転に必要なバッテリー容量を算出する。そして、その算出した結果に基づいて生成された指令で、エレベーターかご毎のバッテリーを、劣化または充電容量不足を検出したバッテリーが接続されたエレベーターかごの駆動用電源に切り替える。【選択図】図7
