Developing a hybrid wireless power transfer system for electric vehicles
Background: Today, automotive research organizations worldwide are actively developing wireless power transfer systems for electric vehicles. The key advantage of such systems is their ability to resupply power on board the moving vehicle without using a contact slider.
Aim: This study aims to increase the energy efficiency of electric vehicles by using a hybrid wireless power transfer system.
Materials and methods: The study used a mathematical model of urban driving cycle as provided by UNECE Regulation No. 83.
Results: We developed a structural diagram of a hybrid wireless power transfer system and determined its operational algorithm for the urban driving cycle. The author reviewed and analyzed the relative contemporary research and development and various wireless power transfer systems for electric vehicles. The target of this study is a magnetic coupling resonant wireless power transfer system with one primary coil for power transfer and a battery of supercapacitors for accumulation.
Conclusion: Automotive companies and research institutes may use the proposed traction voltage system and its operational algorithm to design urban passenger vehicles.
