Electric Vehicle propulsion Systems Present and Future Trends

Environmental pollution is affecting the daily lives of all beings on planet Earth in one way or the other. The prevention, reduction, and elimination of pollution is becoming one of the major objectives of governments all over the world. R&D is going on in several laboratories to reduce the emissions from automobiles. The USA, which has the highest number of automobiles in the world, is pushing for lower emissions. As a result of this concern for environmental pollution, major efforts are underway to develop electric vehicles. In this paper, the present trends and requirements of the primary electric propulsion components — the battery, the motor, and the power converter — are presented. The status of electric vehicle technology and future trends are reviewed.
