Abstract

With the development needs of the new era, electric vehicles have become the preferred means of transportation with their environmentally friendly superiority and are moving towards an intelligent, wireless and grid-based future. However, the wired charging mode of electric vehicles does not meet this requirement and has many drawbacks, such as poor port adaptability, long charging time, and large land and labor costs. The wireless charging mode is naturally free of these problems and has been put into use in micro fields such as cell phone charging and watch charging. How to realize the utilization of wireless power transmission in the field of electric vehicles as soon as possible to realize charging while walking. In this paper, I will illustrate the advantages of Inductively Magnetically Coupled - Wireless Power Transmission (MCR - WPT), construct an optimized MCR - WPT circuit model to realize the wireless charging of battery, and give parameters such as energy utilization through Simulink simulation for theoretical justification. The results show that the MCR - WPT circuit can better realize the wireless charging of batteries with high safety and stability, and the MCR - WPT technology can play its advantages in the future large-scale wireless charging applications.
