A Multi-Channel Wireless Power Transfer Method for Electric Vehicles Based on Magnetic Field Coupling

Abstract

With the continuous development of electric vehicles, wireless power transfer technology has emerged as a new way to supply electric energy to these vehicles. However, the traditional approach of one charging station matching one electric vehicle is no longer sufficient to meet the demand for energy supply. In this regard, this paper proposes a multi-channel wireless power transfer method for electric vehicles based on magnetic coupling. This method can meet the energy supply requirements of multiple electric devices with a single charging station. This paper also provides a charging flowchart and power allocation method to enable efficient utilization of the charging station's power capacity and meet the demands of electric devices. Finally, a simulation model is presented and verified.
