Abstract
An elevator system including: an elevator car configured to travel through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam comprising a first surface and a second surface opposite the first surface; a propulsion system configured to move the elevator car through the elevator shaft; a first on-board energy management system configured to power the propulsion system, the first on-board energy management system is attached to the propulsion system and configured to travel with the propulsion system.
Claims19
An elevator system comprising:
- an elevator car configured to travel through an elevator shaft;
- a first guide beam extending vertically through the elevator shaft, the first guide beam comprising a first surface and a second surface opposite the first surface;
- a propulsion system configured to move the elevator car through the elevator shaft;
- and
- a first on-board energy management system configured to power the propulsion system, the first on-board energy management system is attached to the propulsion system and configured to travel with the propulsion system;
- a trailing cable configured to electrically connect to a power grid, wherein the power grid is configured to charge the first on-board energy management system through the trailing cable when the first on-board energy management system is within a station and traveling horizontally between a first vertical section of the elevator shaft and a second vertical section of the elevator shaft.
A method of operating an elevator system comprising:
- moving, using a propulsion system, an elevator car through an elevator shaft;
- powering, using a first on-board energy management system, the propulsion system;
- and
- moving, using the propulsion system, the elevator car, and the first on-board energy management system to a station to recharge the first on-board energy management system or replace the first on-board energy management system;
- using a trailing cable configured to electrically connect to a power grid to charge the first on-board energy management system, wherein the power grid is configured to charge the first on-board energy management system through the trailing cable when the first on-board energy management system is within the station and traveling horizontally between a first vertical section of the elevator shaft and a second vertical section of the elevator shaft.
