Wireless Power Transfer Systems for Electric Vehicles

Abstract

Cutting the annoying power cables, wireless power transfer technology based on the magnetic resonance and near-field coupling of two-loop resonators has tremendously transformed the way that electrical and electronic devices receive their power. This emerging technology certainly has makes our lives more convenient, comfortable, and productive than any generation before us. By introducing wireless power transfer systems for electric vehicles, the obstacles of transferring energy to the vehicles can be resolved. The driver only needs to park the car and leave. Charging the vehicle's battery becomes an easy task. In dynamic wireless charging application like roadway-powered electric vehicle, the technology also enables battery charging while driving. The electric vehicle is possible to run continuous without stopping. Starting from Tesla's principles of wireless power transfer, this chapter introduces the basic concepts, study method, design principles, and latest developments in wireless power transfer technology.
