Elevator System to Maintain Functionality During a Power Failure
First Claim
1. An elevator system for handling a power outage in a building having a plurality of floors comprising:
- at least one elevator;
an energy calculator connected to the at least one elevator and capable of determining a total energy of the elevator system, a total energy required to handle a power outage, a plan to prepare, and a plan to handle;
a movement controller connected to the at least one elevator and the energy calculator, wherein the movement controller receives the plan to prepare and the plan to handle from the energy calculator, and the movement controller executes the plan to prepare if there is no power outage and the movement controller executes the plan to handle if there is a power outage; and
an elevator drive system connected to the at least one elevator and the movement controller, the movement controller controlling the elevator drive system, and wherein the elevator drive system controls the direction, speed, and stopping of the at least one elevator.

Abstract
The invention provides a system and method for handling power outages in a multiple car elevator system in a building having a plurality of floors. The system includes an energy calculator connected to the elevators, and determines a total energy of the elevator system, a total energy required to handle a power outage, a plan to prepare for a power outage and a plan to handle a power outage. The system also includes a movement controller connected to the elevator(s) and the energy calculator. The movement controller receives the plan to prepare and the plan to handle from the energy calculator, and the movement controller executes the plan to prepare if there is no power outage and the movement controller executes the plan to handle if there is a power outage.
