The mechanical loss of elevator movement is considerably small and the elevator with few passengers in down movement has high power demand during acceleration, as well as high power restitution during deceleration. In the up movement, the reverse phenomenon is observed. The number of up-down cycle exceeds 300 times in a day. However, the regenerative energy is consumed in the braking resistors. Then, the elevators with Ni-MH battery based energy storage system was developed and in use, but the energy saving is 20〜31%. We have studied the elevator with electric double layer capacitor (EDLC) based energy storage system. The EDLC is connected directly to the dc bus which is the input of the inverter. The simulation results shows that the energy saving over 40% is possible even with small EDLC, the EDLC with small inner resistance is important and the voltage balance circuit with resistors can be used.
