Energy-saving elevator energy storage device

How to recover energy from elevator systems?

Energy recovery from elevators’ systems is proposed. Energy storage using supercapacitors and lithium-ion batteries is implemented. Bidirectional power flow is controlled to use the stored energy as auxiliary supply to the load without exchanging with the grid. Emergency energy level is maintained and used in automatic rescue situation.

Can energy efficient elevator systems save energy?

Both proposed systems offered emergency rescue features in addition to storing the regenerated energy from the elevator. Savings up to 20% of consumed energy in an “already” energy efficient elevator system is achieved through the proposed power sharing control strategy.

Which energy storage devices can be embedded on elevators?

Among the wide range of energy storage devices, only three are mature enough and well suited to be embedded on Elevators (i.e., batteries, supercapacitors and flywheels). Batteries have the best energy density, but a bad power density and provide slow dynamic cycles (more than 100 s).

Why is energy recovery important in elevators & auxiliary power supply systems?

Energy recovery in elevators’ systems is vital to achieve higher efficiency. Leaps in power electronics industry enables complex and tight control algorithms for energy recovery and harvesting. Energy recovery and auxiliary power supply system is proposed and analyzed in this manuscript.

Are smart elevators a good choice for time and energy management?

Smart elevators provide substantial promise for time and energy management applications by utilizing cutting edge artificial intelligence and image processing technology. In order to improve operating efficiency, this study designs an elevator system that uses the YOLO model for object detection.

Can intelligent control systems save energy in elevators?

Chen, Lin, and Zhang 10 provide a comprehensive analysis of energy-saving control strategies in elevators, showing that intelligent control systems can achieve up to 20% energy savings by optimizing motor efficiency and reducing idle time.
