Hybrid Propulsion Truck Platform Dually Developed by the U.S. Army and DaimlerChrysler 2001-01-2794
This paper provides an overview of the Hybrid Electric Commercially Based Tactical Truck (COMBATT), a collaborative program between the U.S. Army Tank-automotive and Armaments Command's (TACOM) National Automotive Center (NAC) and the DaimlerChrysler Hybrid Electric Vehicle Platform Engineering Group. As part of the 21st Century Truck Initiative, the COMBATT platforms represent the class 2b (light) trucks. The platforms contain all of the utility and enhanced off-road capability features of the baseline COMBATT platform plus the second generation of a hybrid propulsion system incorporating an integral auxiliary power supply. The hybrid feature increases fuel efficiency, expands operational capability by providing a limited range electric propulsion mode, and enables an extended auxiliary electrical power supply capability. The auxiliary power supply provides up to 20kW of continuous electric power and 30kW of peak electric power for on- or off-board applications.
