“…The increase in cost for WPT recharging hardware may be pretty reasonable when weighed against the benefits of wireless charging, which include reducing the battery's size and savings on long-term operational costs [74]. Compared to diesel buses, buses that are charged wirelessly can experience a reduction in fuel expenses that is greater than eighty per cent, equating to a savings of ninety thousand dollars [75]. It is important to note that the investment in infrastructure would be cost-viable for dynamic inductive charging on highways.…”

The delivery of electricity employing an electromagnetic field that extends across an intervening region is called a wireless power transfer (WPT). This approach paves the way for electric vehicles (EVs) to use newly available options to reduce their environmental impact. This article is a review that examines the WPT technology for use in electric vehicle applications from both the technical aspect and the environmental impact. This review will attempt to accomplish the following objectives: (1) describe the present state of the technology behind the development and application of a WPT across the transportation industry; (2) substantiate the actual implementation of WPT EV systems; and (3) estimate the functioning of the autonomous system, as well as detect the potential stumbling blocks and openings for enhancement. The most recent advancements and implementation in compensating topologies, power electronics converters, and control techniques are dissected and debated scientifically to improve the system’s performance. To evaluate the performance from a sustainable perspective, energy, environmental, and economic factors are utilized, and at the same time, policy drivers and health and safety problems are researched.

Green electricity and green transportation are the primary requirements for smart cities. Maximizing the EV utilization is the key requirement in the development of green transportation. However, the EV technology faces challenges due to the long battery recharging time and heavy batteries to achieve extended driving ranges. Different approaches are investigated to charge the EV by battery swapping, plugin or wireless. Recently the wireless charging approach is gaining popularity because of safety, extended driving range, dynamic charging and human intervention free recharging. However, multiple factors need to considered in the design of WPT system and requires expertise in different domains. This paper discusses a systematic approach on the various parameters involved in a dynamic wireless charging system design. The major functional units in WPT such as charging couplers, compensation network, and power inverters topologies are addressed. Additionally, this paper discusses the issues involved in grid-tied and renewable integrated dynamic charging systems. Moreover, the step by step procesdure is described to understand the process involved in the dynamic charging system design. Finally, various case studies at different power levels are presented to get more insights into practical design.
