Wireless charging for electric vehicles: A comprehensive review of technologies, challenges, and solutions

Abstract

Wireless Power Transfer (WPT) technology is a crucial innovation offering convenience and advancements across various fields. Similarly, electric vehicles (EVs) provide a sustainable solution to reduce pollution. The adoption of EVs depends on factors such as charging duration, accessibility to stations, and safety concerns. While conductive charging remains the dominant method, especially with the advantages of DC fast chargers, wireless charging is emerging as a flexible and convenient alternative, reducing dependence on physical wires. This review covers the fundamentals of WPT technology, various EV charging solutions, and the development of wireless EV charging. It includes discussions on WPT categories, modes of wireless charging, coil topologies, the role of ferrite and shielding, misalignment challenges, compensation topologies, power converters, system control, key challenges and perspectives and key standards for wireless EV charging, highlighting its role in advancing charging infrastructure and promoting EV adoption. • Fundamentals of WPT technology, including categories, and application domains. • A brief history of electric vehicles. • Various electric vehicles (EVs) charging solutions. • The main challenges of wireless EV charging. • Key standards for wireless EVs charging.
