A lift drive system for an energy storage and delivery system includes an electric motor that rotates a driven shaft, a brake assembly for selectively braking the rotation of the driven shaft, and optionally includes a clutch selectively operable to decouple the electric motor from the driven shaft. A steel ribbon is disposed at least partially about and in contact with the driven shaft, where rotation of the driven shaft by the electric motor causes linear movement of the steel ribbon. The steel ribbon can connect at one end to an elevator cage assembly and at an opposite end to a counterweight.

An energy storage assembly includes an energy storage unit. A supervisor is operable to determine a power reference set point based upon a cost function. A storage unit controller is configured to control the energy storage unit to provide electric energy to at least one load based upon a power reference input that is based upon the power reference set point and at least one dynamically changing power profile from the at least one load.

The present invention relates to a method of highly efficiently operating an elevator by analyzing an operation of the elevator, including: a base information collecting step of measuring and collecting information on a change over time in magnitudes of current values of a driving unit when the driving unit for moving the elevator upward or downward moves the elevator upward in a normal state, measuring and collecting information on a change over time in magnitudes of current values of the driving unit when moving the elevator downward, classifying the measured information into driving information of the driving unit when moving the elevator upward and driving information of the driving unit when moving the elevator downward, and storing the driving information of the driving unit when moving the elevator upward and the driving information of the driving unit when moving the elevator downward as base information of the driving unit.

A human-machine-interface formed as a landing operation panel or a landing information panel for an elevator installation has: an interaction unit (3) that responds to actuation by a passenger to generate input signals and/or to output output signals to be perceived by the passenger; a communication unit that transmits the input signals to an elevator and/or receives the output signals from the elevator controller; and a supply unit that supplies electrical energy to the interaction unit and the communication unit, the supply unit having an energy conversion unit and an electricity storage unit, wherein the energy conversion unit converts kinetic energy available in the immediate surroundings of the human-machine-interface into electrical energy, and wherein the electricity storage unit stores the converted electrical energy. The human-machine-interface operates with energy autonomy, i.e. without a supply cable to a central power supply.

Provided is an electricity generating elevator, which includes a cage installed in a shaft formed in a building in order to carry passengers or loads, a drive unit vertically moving the cage along the shaft, and an electricity generation unit including a coil section installed on the cage and a magnetic force generator that is installed in the shaft so as to face the coil section and provides a magnetic force to the coil section so as to generate an induced electromotive force according to a change in a position of the coil section while the cage moves up and down. Thereby, the electricity generating elevator includes the coil section attached to the cage and the magnetic force generator arranged in the shaft at a position facing the coil section, so that electric energy can be produced by the coil section according to a change in a position of the cage while the cage vertically reciprocates in the shaft, and the produced electric energy can be used as a power source for vertically moving the cage. Thus, maintenance expenses of the elevator can be reduced.

The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit and a power storage device. The power storage device includes a supercapacitor unit and a battery unit. The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device.

A method for operating an elevator system, which may include at least two cars that can move independently of one another within a common elevator shaft, may involve determining with an elevator controller to cause a first car of the at least two cars to perform a transportation process from a start stopping point to a destination stopping point. The elevator controller may determine a starting time and travel parameters according to which the first car carries out the transportation process from the start stopping point to the destination stopping point. The starting time and the travel parameters may be determined by taking into account state parameters of a second car of the at least two cars.

A lift system comprises a rail (1) and a carriage assembly (2) comprising a seat (21) or platform (21) for supporting a person to be conveyed along the rail (1), drive means arranged to engage the rail (1) and controllable to drive the carriage assembly (2) along the rail (1), energy storage means arranged to power the drive means, input means operable by a user to provide an input signal indicative of a desired movement of the carriage assembly (2) along the rail (1), and control means arranged to receive the input signal and control the drive means in response to the input signal.
