Abstract: A method of operating an elevator system is presented. The method comprises controlling, using a controller, a plurality of components of the elevator system. The controlling comprises operating at least one of an internal power source, an elevator car, a drive unit, a power conversion device, and a brake. The method also comprises detecting, using the controller, when an external power source is unavailable; deactivating, using the controller, the power conversion device when an external power source is unavailable; and determining, using the controller, a mode of the elevator car. The mode includes at least one of a motoring mode and a near balance mode. The method further comprises connecting, using the controller, to an internal power source, when at least one of the motoring mode and the near balance mode is determined; and increasing, using the internal power source, voltage of the drive unit.
