A ropeless elevator system includes a vertically extending first lane, a vertically extending second lane, and a transfer station extending between and in communication with the first and second lanes. An elevator car is disposed in and is constructed and arranged to move through the transfer station and the first and second lanes. A propulsion system of the elevator system propels the elevator car through at least the first and second lanes and carries a supplemental DC energy storage device for providing supplemental energy to the elevator car during normal operation. A wireless power transfer system of the elevator system is configured to periodically charge the DC energy storage device.
