Proposal Military Hybrid Vehicle Optimization and Control *

Hybrid vehiclE's arE.> increa..-;ingly common in the passenger car marketplace and in commercial applications such as dE>livery trucks and transit busses. ThE>se hybrids an' justifiable due to tl10ir inCI·eascd fuel efficiency ru1d thf' associated cost benefit. It is remarkable then, that there are no deployed military hybrid vehicles when fuel costs as high as $100 per liter are common in the battlefield. An ab. ence of military hybrid vehicles is not due to a lack of investment in research and development, but rather because applying hybrid vchide architecture in a classical sense to a military application has challenges that make fielding such a vehicle prohibitive. These chall(-'nges include inconsistent duty cycles unique vehicle requirements and the ab ·ence of holistic view of energy. The proposed research addresses these challenges while illuminating the comprehensive b<:>nefits of military hybrid vehicks with respect to operatioual energy which includes propulsion power, electric power for government furnished equipuwnt (GFE), silent watch capability, and vehicle-to-grid (V2G) mobile energy exchange ru1d storage. By treating a military vehicle as a microgrid, a methodology for developing optimal battery state of charge (SOC) profile for military duty cycles will be developed. A proof of concept will be presented along with the detailed steps necPssary to extend this work into a military euvironmcnt, indnding reduced order optimization and sensitivity analy:;is. Finally, the impact and timeline of this doctoral research project will be explained.*
