Research on Electromagnetic Exposure Measurement Method for Electric Vehicle Wireless Charging System

The use of wireless charging technology to charge electric vehicles not only achieves the purpose of safety and convenience, but also reduces the battery capacity of electric vehicles. In this paper, the electromagnetic exposure problem of electric vehicle wireless charging system is taken as the research object, the equivalent circuit model is established, and the analytical formula of output power and transmission efficiency is solved. At the same time, the magnetic field distribution characteristics are obtained. Finally, a set of electromagnetic exposure measurement methods for electric vehicle wireless charging system was proposed, and the electromagnetic exposure experiment of mouse immune system was carried out. Combined with relevant electromagnetic standards, it was concluded that the electromagnetic field did not affect the mouse immune system under the experimental conditions.
