Research on electromagnetic radiation safety of electric vehicle wireless charging system

The wireless charging technology of electric vehicles utilizes magnetic induction for energy transmission. Due to the use of non-direct contact methods, it can effectively avoid the drawbacks of exposed charging wires, and has obvious advantages in effectively promoting the intelligent process of vehicles. Therefore, it has received increasing attention. With the application of wireless charging technology, people have begun to pay attention to the impact of its electromagnetic radiation on the health of passengers and the public. On the other hand, with the improvement of medical level, the compatibility between wireless charging system and active implantable medical devices such as cardiac pacemakers, Cochlear implant has also attracted extensive attention. Firstly, this paper analyzes the existing wireless charging limits and testing method standards, and then takes a certain wireless charging system as an example to test the electric and magnetic field radiation values inside and outside the vehicle during wireless charging. By comparing with the standard limits, it can be concluded that the electromagnetic radiation of the vehicle model meets the standard.
