Abstract:
The electrification of conventional vehicles, ranging from passenger vehicles and trucks to ground vehicles such as agricultural tractors, construction equipment and military vehicles, can potentially offer improvements in fuel economy and emissions. Nearly all conventional vehicles are powered by a gasoline or diesel fueled internal combustion engine that converts the energy stored in the fuel to rotating power out of the engine. Internal combustion engines are relatively inefficient, typically converting only 25 to 35 percent of the input energy in the fuel to the output shaft to do useful work. With heavily fluctuating fuel prices, the total cost of ownership of loaders, excavators, and other classes of ground vehicles is nowadays strongly influenced by the fuel costs. Moreover, there is growing concern about CO2- emissions caused by the burning of fossil fuels as well as about the long-term availability of these fuels. The military is particularly interested in the electrification of vehicles because the attributes that these vehicles possess offer exceptional potential for the military to achieve its long-term objectives of developing a highly mobile, lethal fighting force.
