In an energy-saving elevator system using a power storage device (30) by secondary batteries etc., the power storage device (30) includes a power storage part (31) which stores or discharges DC power, a charging/discharging circuit part (32) which performs the charging/discharging of the power storage part (31), a measuring part (33) which measures at least one of a temperature of the power storage part (31) or an input/output current or voltage thereof, and a charging/discharging control part (34) which controls the charging/discharging of the power storage part (31) according to an output of the measuring part (33) and further includes an air blowing part (35) which blows air to the power storage part (31) as necessary. This power storage device (30) or at least a prescribed component part thereof is arranged within an elevator shaft (1). Preferably, this power storage device (30) or at least a prescribed component part thereof is arranged immediately above or immediately under a control panel (10) disposed within the shaft (1) so as to save space. <IMAGE> |
