Frontier and Prospect of energy conversion and storage of electric vehicles

Abstract:
Over the past decade, people began to pay more and more attention to the emerging field of electric vehicles. As the development direction of future vehicles, in addition to the main advantages of environmental friendliness and fossil energy conservation, electric vehicles also have other unique application potentials, such as V2G technology. This paper explains, analyzes and compares the AC / DC charging technology through the first part; The second part compares the advantages and disadvantages of the existing main types of on-board batteries of electric vehicles, and introduces the latest research results; Through the third part, the principle of V2G technology is displayed and its application prospect is analyzed. Finally, it is concluded that DC charging pile may become the mainstream in the future, vehicle battery will be more efficient and environmentally friendly in the future, and V2G technology has great application prospects. This paper summarizes the recent breakthroughs in related fields, explains its basic concepts and principles, and puts forward some ideas for future development. Through this paper, readers can have a preliminary concept of the current situation and future development and application of key fields of electric vehicles.
