This article summarizes the research on low-frequency magnetic field of electric vehicles from 1995 to 2021, and analyzes the characteristics of changes in the internal magnetic field of electric vehicles in terms of operating conditions, frequency spectrum, spatial distribution of the field, change of the components and the changes of the field values over time. Research on exposure to magnetic fields caused by new technologies such as wireless power transmission is included as well. In addition, for determining the induced electric field (basic limits) of the human body when being exposed to the low-frequency magnetic field, the commonly used electromagnetic numerical methods are presented. The simulation results are summarized as well. On this basis, in response to the hot topics reflected in the literature survey, some urgent key future studies are suggested.Key words：electric vehicles (EV)  low frequency magnetic fields  magnetic field measurement  electromagnetic simulation  wireless power transmission (WPT)   收稿日期: 2021-11-29     基金资助:国家自然科学基金（61971445）作者简介: 姜昊宇（1998—）,男,天津市人,硕士,主要从事电磁场生物效应方面的研究工作。引用本文:   姜昊宇, 张晨, 巫彤宁. 电动汽车低频磁场人体暴露安全性研究[J]. 电气技术, 2022, 23(7): 1-6.
