Abstract

An elevator system including a hoistway, an elevator component disposed in the hoistway, and a power assembly disposed in the hoistway, the power assembly including a first power component disposed in the hoistway, the first power component comprising a first power connection, and a second power component operably coupled to the elevator component; wherein the first power component is configured to provide wireless power to the second power component.

Claims

1. An elevator system comprising:

a hoistway;

an elevator component disposed in the hoistway; and

a power assembly disposed in the hoistway, the power assembly comprising;

a first power component disposed in the hoistway, the first power component comprising a first power connection; and

a second power component operably coupled to the elevator component;

wherein the first power component is configured to provide wireless power to the second power component.

2. The elevator system of claim 1, wherein the second power component is configured to connect to the first power component via a direct connection or an indirect connection.

3. The elevator system of claim 1, wherein the first power component is operably coupled to a power source.

4. The elevator system of claim 1, wherein the second power component comprises:

a second power connection;

a first power storage device operably coupled to the second power connector;

a safety actuation controller comprising a communication module, the safety actuation controller operably coupled to the first power storage device; and

a second power storage device operably coupled to the safety actuation controller.

5. The elevator system of claim 1, further comprising a guide rail disposed in the hoistway;
