An auxiliary power system includes an engine balance system, an integrated alternator/starter, a thermal management system, noise-vibration-harshness control system, an emissions/fuel economy system, an APU master control unit, and a vehicle control system. The thermal management system includes an alternator/starter cooling assembly for cooling an alternator/starter in the auxiliary power system, an engine lubricating/cooling assembly for cooling an engine in the auxiliary power system, an assembly for collecting a cooling material after passing through the alternator/starter and the engine, an assembly for scavenging the cooling material from the collecting assembly to a first heat exchanger, an assembly for circulating the cooling material back to the alternator/starter and the engine, and a second heat exchanger which is disposed on the circulating assembly between the first heat exchanger and an alternator/starter inlet.
