A Systematic Review of Dynamic Wireless Charging System for Electric Transportation

Green electricity and green transportation are the primary requirements for smart cities. Maximizing EV utilization is the key requirement in the development of green transportation. However, 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 be considered in the design of the WPT system and require 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 procedure 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.
