This study provides a comprehensive review and discussion of the history, current status, and emerging trends in wireless electric vehicle (EV) charging. The literature is divided into two main groups: technical aspects and operations and systems. The paper aims to address the gaps in existing reviews by combining both perspectives into a single guide for researchers, policymakers, and government entities. The study highlights the advantages of wireless charging over traditional wired charging, such as improved safety, flexibility, and cost-effectiveness. It also discusses the challenges and opportunities in extending the driving range of EVs through dynamic wireless charging systems.
The technical background covers wireless power transfer (WPT) methods, including near-field, medium-field, and far-field charging. Near-field methods include capacitive, inductive, and resonant inductive power transfer (RIPT), while medium-field charging involves magnetic gear technology. Far-field charging technologies, such as laser, microwave, and radio wave charging, are expected to be the future of wireless EV charging due to their high range and power levels.
The operations and systems perspective focuses on the design and implementation of wireless charging systems, including compensation topologies, converter topologies, and communication systems. Compensation networks are used to achieve resonance and improve power transfer efficiency. Converter topologies are crucial for power supply control and load parameter management. Communication systems facilitate data transfer for feedback, control, and safety measures.
The study concludes by emphasizing the need for further research and standardization to ensure the safe, efficient, and widespread adoption of wireless EV charging.This study provides a comprehensive review and discussion of the history, current status, and emerging trends in wireless electric vehicle (EV) charging.
