IOT Based Wireless Power Transfer for EV

Wireless Power Transfer (WPT) technology has emerged as a promising solution for charging electric vehicles (EVs), offering enhanced convenience, safety, and reliability compared to conventional wired charging methods. This paper presents an overview of wireless power transfer systems for electric vehicle applications, focusing on inductive and resonant coupling techniques that enable efficient energy transmission across an air gap. Key components of WPT systems, including power electronics, coupling coils, compensation networks, and control strategies, are discussed in detail. The performance of wireless charging is evaluated in terms of power transfer efficiency, alignment tolerance, electromagnetic compatibility, and system scalability. Additionally, challenges such as coil misalignment, power losses, electromagnetic field exposure, and infrastructure cost are analyzed. Recent advancements in dynamic wireless charging, standardization efforts, and integration with smart grid technologies are also highlighted
