Abstract
As the global energy crisis and environmental pollution problems become increasingly severe, electric vehicles, as an important part of green transportation, have become an irreversible trend in their popularization. However, traditional wired charging methods have many limitations in terms of convenience and user experience, making wireless charging technology a research hotspot. This study aims to explore the principles, implementation methods, and impact on the power grid of wireless charging technology for electric vehicles, and proposes an optimized wireless charging system design. By combining theoretical analysis, simulation modeling, and experimental verification, this paper thoroughly evaluates the efficiency, safety, and electromagnetic compatibility of wireless charging technology, and further analyzes the potential impact of large-scale deployment of wireless charging facilities on power load distribution and grid stability. The research results show that magnetic resonance coupling-based wireless charging technology has high energy transfer efficiency and strong adaptability, significantly enhancing the user charging experience; at the same time, by introducing intelligent scheduling algorithms and dynamic power control strategies, it can effectively mitigate the impact of wireless charging on the power grid.
