Document Type and Number:
WIPO Patent Application WO/2003/072478
Kind Code:
A1
Abstract:
A power supply system comprising a power supply having a secondary cell and a charging&sol discharging controller for controlling the charging&sol discharging of the secondary cell, characterized in that the power supply is connected to a power system of a building in series or parallel, and the power supply or a part of it is installed inside an entrance frame of a landing of an elevator. Since the power supply or a part of it is installed inside an entrance frame of a landing of an elevator, effective use of the building is achieved. Further, since the power supply or a part of it is installed inside the entrance frame of the elevator landing, the maintenance work is facilitated. The lead−in cable of the power supply installed inside of the elevator landing is only the power supply line (and the signal line of a power sensor), thereby facilitating the installation work.
