Abstract

The internal combustion engine (ICE) vehicle at the present is a major source of urban pollution. According to figures released by the U.S. Environmental Protection Agency (EPA), conventional ICE vehicles currently contribute 40%–50% of ozone (nonmethane organic gases NMOG), 80%–90% of carbon monoxide (CO), and 50%–60% of air toxins (nitrogen oxides NOx) found in urban areas. Beside air pollution, the other main objection regarding ICE automobiles is their extremely low efficiency use of fossil fuel. Hence, the problem associated with ICE automobiles is threefold: environmental, economical, as well as political. These concerns have forced governments all over the world to consider alternative vehicle concepts.
Reducing vehicular emissions and enhancing fuel economy will be effective in improving the air quality. Recent advances in diesel combustion technologies, better afterburners and catalytic oxidizers, and use of alternative fuels such as compressed natural gas (CNG), propane, and methanol have resulted in overall reduction in the emission of particulate matters and other gaseous emissions such as volatile organic compounds, nitric oxides, and oxides of carbons. In light of increased use of cars and other public transportation, and ever more congested traffics, additional steps must be taken to reduce emissions even further.
The most efficient way of reducing the energy consumed by automobiles is to use more energy efficient propulsion systems like electric vehicle.
Electric vehicles (EVs) offer the most promising solutions to reduce vehicular emissions. EVs constitute the only commonly known group of automobiles that qualified as zero emission vehicles (ZEVs). These vehicles use electric motors for propulsion and batteries as electrical energy storage devices.
The technology for electric vehicles is developing at a fairly rapid pace, as new battery technologies evolve, higher efficiency drivetrains are developed, and alternative energy sources, such as fuel cells, approach practicality. In order to evaluate these new components and determine what is required to meet specified performance criteria, computer simulation tools will be used.
In this thesis, a comprehensive investigation of the switched reluctance motor as well as the electric vehicle has been accomplished.
The construction, the principle of operation and the electromechanical energy conversion concept of the switched reluctance motor are explained in detail.
The vehicle dynamics are also illustrated. And then a detailed method for the sizing the major components of the electric vehicle is presented.
Considerable attention is given for deriving a mathematical modeling for each part in the electric vehicle system. Moreover, the performance characteristics of the SRM against the rotor position as well as the average characteristics of the SRM, against the motor speed at variable motor terminal voltage, turn on and turn off angle are obtained using MATLAB programming language.
Finally the performance characteristics, for each part in the vehicle system, are obtained when the vehicle is accelerated under voltage, turn on and turn off angle control of switched reluctance motor.
