Experimental evaluation of parallel hybrid medium-duty tactical truck

Abstract

Fuel economy improvement on medium-duty tactical truck has and continues to be a significant initiative for the U.S. Army. The Crankshaft-Integrated-Starter-Generator (C-ISG) is one of the full hybrid propulsions to improve the fuel economy. The C-ISG configuration is attractive because one electric machine can be used to propel the vehicle, to start the engine, and to be function as a generator. The C-ISG has been implemented in one M1083A1 5-ton tactical cargo truck. This paper presents the experimental evaluation of the C-ISG hybrid truck performance characteristics compared to the conventional truck. The evaluated performance characteristics include all electric range for on- and off-road mission cycles, fuel consumption, as well as the battery charging profile and the silent watch time duration in the static tests.
