Abstract

An auxiliary power unit (APU) for aircraft is provided. The APU includes one or more battery modules for storing electrical power and an integrated controller adapted to operate the one or more battery modules for electrically powering aircraft subsystems for preflight readiness. A remote interface is communicatively coupled with the integrated controller and is adapted for displaying data from the APU and for receiving user instructions for transmission to the integrated controller for governing flow of electrical current between the APU and the aircraft subsystems.
