One of the barriers to fielding a military hybrid vehicle is the absence of a holistic view of a vehicle's energy. This paper introduces the concept of treating a military vehicle as a microgrid and utilizing energy optimization methods from stationary microgrids, namely battery state of charge (SOC) optimization. This analysis illuminates the comprehensive benefits of military hybrid vehicles with respect to operational energy, which includes propulsion power, electric power for government furnished equipment (GFE), silent watch capability, and vehicle-to-grid (V2G) mobile energy exchange and storage. V2G is especially important in a military setting, where vehicles may be deployed to assist or replace an energy source, therefore common optimization methods become increasingly important and advantageous. It is shown that optimizing SOC can lead to fuel economy improvements over a drive cycle. In addition, the optimal SOC profile determination is explored to allow for expansion and more complex drive cycles. [Unclassified. Distribution Statement A. Approved for public release.]
