Abstract
The industrialization of electric vehicles has entered a period of rapid growth, and the wireless charging technology of electric vehicles, which has the advantages of flexibility, high efficiency and non-contact, has attracted widespread attention around the world. However, the potential electromagnetic environmental safety problems caused by wireless power transfer system to the users and surrounding people are gradually exposed to the public. In order to promote the standardized development of electric vehicle wireless power transfer systems, JASO TP-13002:2013, IEC TS 61980-1:2015, SAE J2954, ISO 19363: 2020, GB/T 38775.4- 2020 (China) and other standards related to the electromagnetic environment of wireless power transfer systems have been successively released. In this paper, the electromagnetic environment limits and test methods in the above standards were compared. It can be seen that the test methods are basically similar, and the standard limits are also consistent. The electromagnetic environment for wireless charging in electric vehicles tests results showed that the values of magnetic induction inside and outside the vehicle were below the limits established in ICNIRP Guidelines.
