The function of the elevator energy regenerative feedback device:

Technical principle: The elevator energy regenerative feedback energy storage technology uses energy storage devices such as lithium batteries or supercapacitors to capture the regenerative energy generated by the elevator during different movements. These movements include deceleration braking, empty load (light load) upward movement, and full load (heavy load) downward movement.

Energy storage: During deceleration braking, empty load upward movement, or full load downward movement, the regenerative energy generated by the traction motor is stored in the energy storage device, instead of being dissipated. This can avoid energy waste and effectively recover electrical energy.

Reuse: The electrical energy stored in the energy storage device can be used for various purposes, such as providing power for the elevator to restart or driving lighting, ventilation, and other equipment. This can effectively utilize electrical energy and reduce power consumption.

Effect: By implementing elevator energy regenerative feedback energy storage technology, the effect of recovering energy and saving power consumption can be achieved. This helps improve the energy efficiency of the elevator system, reduce reliance on external power supply, lower operating costs, and reduce environmental impact.
