The status of WPT development and applications in the transportation sector.The challenges and opportunities in terms of Technology and sustainabilityperformance have been enumerated and discussed. The first section was a review ofthe technical aspects of both stationary and dynamic charging systems in three areas:coil design; compensation topologies; and power electronics converters and controlmethods. Progress in Technology has led to improved system performance. Stationary wireless charging systems have comparable system performance to conductive charging systems, and dynamic wireless charging systems are on the path to achieve the charging of vehicles in motion. From the technical perspective, major research gaps are: how to improve the system efficiency of dynamic charging systems and maximize the amount of energy received by vehicles at high speed in a limited charging lane range; and how to balance the size of the charging system and its misalignment tolerance and efficiency. From the sustainability perspective, WPT EVs have the trade-off of large infrastructure deployment versus the benefits of battery downsizing and vehicle light weighting.
