China Elevator technology is basically the same as when Eliza Otis made safety brakes for elevators in the 1860s. Although the motors used in elevators may have made significant improvements, the principle remains the same.

Regenerative braking technology is gradually being accepted in many different areas of industry. It is ubiquitous in EVs and hybrids. Using normal braking technology, the kinetic energy of a moving vehicle is converted to heat by applying brakes to the wheels. All kinetic energy has disappeared.

The China elevator is a prime example of a vehicle that regenerative braking technology can produce excellent results. This is because the weight of the elevator ensures that no more than 55% of the China elevator capacity must be moved or stopped by inputting energy. Therefore, the power can be relatively low energy costs established. By recycling some of the energy in the battery, elevator efficiency is greatly increased. The use of regenerative braking technology to transform the elevator is relatively simple, because almost all of the elevators use DC-driven motors to provide more stable acceleration. Inputting DC from the battery is almost trivial. Only the brake mechanism needs to be replaced.

The use of a continuously variable transmission (CVT) allows the transmission of the motor to use a gear ratio that provides maximum efficiency. Continuously variable transmission can move between continuously variable transmission, providing smooth acceleration. Using CVT in an elevator can increase efficiency by using a transmission ratio that best suits the weight difference between the current weight of the elevator and the weight of the counterweight.

The elevator control system, which may be the only part of the elevator, saw major improvements over the last century. Not long ago, each elevator had an operator who manually controlled the elevator and manually started the elevator according to the passenger's request and the request from the person waiting for the elevator. The system is replaced by a set of buttons in the elevator with only one button per floor and two buttons for calling the elevator - the up button and the down button. This method enables the elevator to determine whether the direction the elevator is traveling is related to the person waiting.
