A Novel Reconstruction Approach to Elevator Energy

Building energy consumption accounts for approximately 1/3 of the total energy consumption in China. In high-rise buildings, the energy consumption of elevator systems accounts for approximately 5–15% of the total energy consumption of buildings [5,6]. Then a supercapacitor was used for an elevator''s energy storage device because of its
