Abstract

Electric vehicles (EVs) are becoming more and more popular in various fields because they have many advantages over traditional petrol vehicles. However, as EVs move towards intelligence, the limitations of traditional wired Power are exposed, not only do you need to manually plug and unplug the charging gun, but also are limited by the geographic location of the charging piles, range anxiety and lack of charging convenience are always the core issues affecting the user experience, and restricting the industry from making further breakthroughs. In this context, wireless power transfer (WPT) has become a key direction to solve the pain points. This paper focuses on WPT for EVs and systematically explains the principle of WPT (mainly electromagnetic induction and electromagnetic resonance). At the same time, it puts forward the core challenges faced by new energy electric vehicles, including improving WPT efficiency, reducing transmission loss, lowering cost, and finally provides some optimization directions for the future. With the advantages of convenience and compatibility of wireless power, it is expected to become the mainstream charging method for EVs in the future, and the research content provides scientific reference for the development of the EV industry.
