Research on Energy Supply Modes of Electric Vehicle

Abstract

This paper studies the development and application of electric vehicle (EV) at home and abroad. Through the research of the application and energy supply of EV, analysis and summary the two viable energy supply modes in current technical situation. One model is the vehicle charge; other is the quick-replacement battery mode, also known as electric changing mode. Both modes of energy supply were compared and analyzed. The technology of vehicle charging mode is achieved with lower degree of difficulty and its application is relatively easy in the early development stages of EV, but requires large-scale construction of charging pillars. When EV becomes more popular, it has greater pressure on the grid and would not be conducive to battery protection. Electric changing mode can quickly replace the battery, so that to provide EV users with the convenience and make the energy supplies for EV as easy as refueling. But it is difficult to achieve a unified standard technical and the cost for electric changing equipment is larger. The reference observations of future EV electric changing equipment are made in the summary.
