Wireless Charging for Electric Vehicles: A Review

In terms of performance and range, electric vehicles (EVs) have lately improved. Several commercial models are now on the market, and the number of EVs on the road is constantly rising. Although the majority of electric vehicles are currently charged via electric cables, the companies like Tesla, BMW, and Mercedes Benz have started to design and manufacture electric vehicles that are charged wirelessly and that do not necessitate the use of inconvenient wires. Wireless charging further broadens the scope of dynamic charging, which includes charging when driving. When this is discovered, EVs’ electric driving range will be unrestricted, and battery capability requirements will be drastically reduced. This has been emphasized and endorsed around the world, with the United Kingdom, Germany, and South Korea leading the way. This study provides a comprehensive analysis of the literature on electric vehicle wireless charging. Wireless charging's key technological components are summed up and equated, including compensation configurations, coil styling, and connectivity. To boost the charging power, a novel way to using superconductivity materials in coil designs is examined, as well as their possible effects on wireless charging. Besides that, the health and safety risks associated with wireless charging, and the rules that regulate them, are addressed. From an economic aspect, the costs of various wireless charging technologies have also been summed up and analyzed.
