Abstract
The drum type self-propelled elevator which can be installed in the small hoistway area was proposed in the previous paper. However this elevator system needs much electric power, because it has no counter weight. To solve this problem, regenerative power storage system is effective. In this paper, electric double layer capacitor (EDLC) is proposed as an energy storage device for this selfpropelled elevator. EDLC can operate in high/low ambient temperature and has long life span. The EDLC*s performance affected by the voltage, charge/discharge current, ambient temperature and starting frequency is investigated. And the operation of the energy storage system which is installed in the experimental self-propelled elevator is confirmed.
