Comprehensive review of wireless power transfer systems for electric vehicle charging applications
摘要
Wireless power transfer (WPT) technology has revolutionized the charging processes of electric vehicle (EV), presenting a viable alternative to traditional wired charging methods. This paper provides a fundamental exploration of WPT, emphasizing its application in EV charging. The paper examines various WPT technologies, design considerations, and the associated international standards. A critical analysis of the current WPT technological challenges, such as misalignment, is discussed, highlighting effective strategies like multi-coil configurations and dynamic control systems that adapt to variations in alignment, enhancing efficiency and robustness. These methods significantly mitigate the common misalignment issues in deploying WPT systems, ensuring higher operational effectiveness and reliability. This analysis shows that WPT systems achieve power Transfer efficiencies of over 90% at distances up to
