Development of charging technology for new energy vehicles

Abstract

In the context of a global energy shortage, new energy vehicles are gradually becoming the mainstream trend of future automotive development. The development of fast and safe charging methods will bring a better experience to new energy vehicle users and gradually solve the problem of mileage anxiety for new energy vehicle users. At present, the main charging method of new energy vehicles is wired charging, but this charging mode charging time is slow and due to the external influence of the charging environment, causing the battery to overcharge the cars spontaneous combustion phenomenon, the application of wireless charging and power exchange technology to the future charging technology, wireless charging can bring higher charging efficiency and power exchange technology can bring similar to the fuel car replenishment energy experience. This paper first introduces the meaning of the three charging technologies and analyses their advantages and disadvantages. The three charging methods are described separately for wireless charging technology and compared with each other to arrive at the most suitable for future development. By comparing these three charging technologies, it can be seen that wireless charging technology is more suitable for the development trend of unopened new energy vehicle charging technology, and finally, the difficulties that need to be overcome for the future development of wireless charging are briefly described. This paper has important implications for developing new energy vehicle charging technology and popularizing the use of new energy vehicles.
