We have studied the elevator with electric double layer capacitor (EDLC) based energy storage system. This paper shows detailed power simulation using the RC-ladder equivalent circuit, which has a voltage dependent capacitor and considering power supply by power source, braking resistance, and series connection of EDLC. Simulation result shows that the energy saving depends mainly on internal-resistance and capacitance of EDLC. The simulation result also shows that EDLC with low internal-resistance is suited for this system and energy saving rate over 40% is obtained.
