PROBLEM TO BE SOLVED: To provide a regenerative power storage device of an elevator that can determine the lifetime of the power storage device in normal operation.SOLUTION: A regenerative power storage device of an elevator includes: a power storage element 14 which stores electric power generated in regenerative operation of the elevator 1 and discharges the electric power in power running operation of the elevator 1; voltage detection means 16 of detecting a voltage value of the power storage element 14; time measurement means 17 of measuring the time when the voltage value is detected; and replacement period determination means 18 of comparing a computational value based upon the voltage value and time with a predetermined reference value, and determining that the power storage element is dead when the computational value exceeds the reference value.

    【課題】通常の運転時において、蓄電装置の寿命を判断できるエレベータの回生蓄電装置を提供する。【解決手段】この発明に係るエレベータの回生蓄電装置は、エレベータ1の回生運転時に発生した電力を蓄電し、エレベータ1の力行運転時に電力を放電する蓄電素子14と、蓄電素子14の電圧値を検出する電圧検出手段16と、電圧値が検出される時間を計測する時間計測手段17と、電圧値と時間とに基づく演算値と予め定められた基準値とを比較し、演算値が基準値を超えた場合、蓄電素子が寿命であると判断する交換時期判定手段18とを備える。【選択図】図2
