ABSTRACT
In this paper, structure of electric vehicles is initially reviewed. Then electric vehicles propulsion system which consists of energy storage system, power electronic system and electric motor is reviewed in detail. Besides, performance of electric vehicles and advantages and disadvantages of this technology are also discussed.
Key words: propulsion system, battery, converter/inverter, motor, battery.
INTRODUCTION
The review is finished through searching various scholarly articles, books, dissertations, conference proceedings which are relevant to electric vehicle technology. From Automotive Power Generation and Control, the history and developments of electric vehicle technology has been reviewed. ELECTRIC AND ELECTRIC HYBRID VEHICLE TECHNOLOGY: A SURVEY interpreted the basic structure of electric vehicles, which consists of battery, converter, motor, changeable or fixed gear and differential gear. The critical segment of electric vehicle technology is reviewed from Present Status and Future Trends in Electric Vehicle Propulsion Technologies. Moreover, performance of electric vehicles is also reviewed from Automotive Electrical Systems-the Power Electronics Market of The Future and Electric and Hybrid Vehicle Technologies Change Ahead. At last, the paper is also discussed advantages and disadvantages of electric vehicle technology by searching some scholar journals and websites. In addition, the paper also used other articles, books, dissertations about electric vehicle technology to assist reviewing the above areas.
MAIN SECTION
DEVELOPMENT OF ELECTRIC VEHICLE TECHNOLOGY
Electric vehicle technology has been around since the late 1800s. Electric vehicles were very poplar and a number of EVs were sold until about 1918. Once the EV technology declined due to gasoline prices falling, but the technology was resumed by General Motors (GM) because of environmental concerns in
