An auxiliary power unit (APU) system for an aircraft can include a fuel consuming system (101) configured to generate and output electrical energy for use by one or more aircraft systems and a battery system (103) configured to output stored electrical energy for use by the one or more aircraft systems. The fuel consuming system can include a fuel consuming APU (105), and an APU generator (107) operatively connected to the fuel consuming APU and configured to convert APU motion into APU generator alternating current (AC). The system can include a high voltage AC line (111) operatively connected to the generator. The battery system can include a battery (113) configured to output battery direct current (DC).
