Abstract - The growing adoption of electric cars (EVs) has driven the need for efficient and handy charging answers. traditional plug-in charging strategies face challenges associated with physical wear and tear, consumer inconvenience, and restricted charging infrastructure accessibility. wi-fi power transfer (WPT) has emerged as a promising alternative that gets rid of the want for physical connectors, enhancing comfort, safety, and efficiency in EV charging. but, WPT generation faces challenges inclusive of strength switch efficiency, misalignment issues, electromagnetic interference (EMI), and energy losses. This study explores the layout and efficiency optimization of WPT systems for EV charging, focusing on resonant inductive coupling, reimbursement circuit topologies, and electricity electronics advancements. diverse WPT architectures, consisting of desk bound, dynamic, and bidirectional wireless charging, are analyzed for their overall performance and feasibility in actual-global programs. A MATLAB/Simulink-based totally simulation is conducted to assess the performance of different coil configurations, electricity manages strategies, and frequency tuning strategies to enhance power switch. The consequences reveal that optimized coil design, adaptive resonance tuning, and AI-driven control algorithms significantly enhance strength switch efficiency and machine reliability. future studies should consciousness on hybrid WPT technologies, clever grid integration, and electricity storage solutions to permit scalable and excessive-overall performance EV wi-fi charging infrastructure.
