Study on the Charging Technology Roadmap and Development Trend of Electric Vehicle

Electric vehicles (EV) are important to the successful achievement of carbon peaking and carbon neutrality goals, and the development of electric vehicles must accelerate the construction of charging and switching infrastructure and improve the level of charging infrastructure services. In this paper, the roadmap and development trend of electric vehicle charging technology are studied. The three charging technology roadmaps of EV conduction charging technology, wireless charging technology and power exchange technology are analyzed, and the future EV charging technology development trend is analyzed in terms of AC charging, DC charging, power exchange technology and wireless charging technology. This paper concludes that: in the future, AC charging is still the main energy replenishment technology in China, and the proportion of orderly charging will gradually increase; DC charging may be polarized, with high-power charging in the public sector and DC low-power slow charging in the private sector; power exchange technology is an important supplement for electric vehicle electric energy replenishment, and is expected to tend to standardization and shared development in the future; wireless charging technology is still in the exploration stage, and small-scale Commercial operation will take some time. This paper has certain reference value for the technical development planning of electric vehicle enterprises and the formulation of relevant government policies.
