Abstract

An elevator system includes a hoistway, an elevator car movable along the hoistway, and a power management and transfer system. The power management and transfer system includes an electrical power source, a hoistway contactor secured in the hoistway and operably connected to the electrical power source, and a car contactor disposed at the elevator car, such that when the car contactor is brought into operable contact with the hoistway contactor, electrical power is transferrable between the power source and the elevator car.
