Research on Charging Mode and Efficiency of New Energy Vehicles

With the increasingly serious global environmental problems and the depletion of fossil fuel resources, new energy vehicles, especially electric vehicles, have become a key way to achieve sustainable development. However, the main challenges limiting the wide application of new energy vehicles remain the diversity of charging methods and their efficiency. This paper based on existing literature and data research systematically analyzes the technical characteristics, efficiency and application scenarios of DC fast charging, AC home charging and other charging methods. By discussing the energy efficiency of charging equipment, the energy loss during charging, and the factors affecting the charging mode and efficiency, this paper aims to provide methods and strategies to improve the charging efficiency. In addition, the study also assesses the impact of different charging methods on the development of the new energy vehicle market, revealing the importance of efficient charging methods in driving market growth. Through the comparison of DC fast charging and AC home charging, the existing problems and future optimization direction of current charging methods are revealed.
