The market share of pure electric vehicle (PEV) as a green transportation steadily increases as the global demand for renewable energy sources and environmentally friendly mobility continues to increase. However, during PEV operation, the inverter system, as the key power conversion device, generates strong electromagnetic field in the local space. Long-term exposure to such electromagnetic environments may have potential effects on human body. In this study, the electromagnetic environment model of the PEV body, human body and simplified inverter is established. The finite element software, COMSOL Multiphysics, is used to calculate and analyse the variations in the induction field in different tissues of the driver and rear passenger, caused by the electromagnetic field generated by the inverter system operating at maximum power. The electromagnetic exposure level of the driver and rear passenger is assessed. Results show significant differences in the electromagnetic exposure levels of different seating positions in the vehicles. The electromagnetic exposure level in the driver's body is higher than that of the rear passenger, but it does not exceed the exposure limits defined by the International Commission for Non-ionizing Radiation Protection. This finding effectively complements the study on evaluating the safety of the electromagnetic environment of PEV and improves public awareness.
随着全球对可再生能源和环保出行的需求持续增长，纯电动汽车（PEV）作为一种绿色交通工具，其市场份额稳步上升。然而，在纯电动汽车运行过程中，逆变器系统作为关键的功率转换装置，会在局部空间产生强电磁场。长期暴露于这样的电磁环境中可能会对人体产生潜在影响。在本研究中，建立了纯电动汽车车身、人体和简化逆变器的电磁环境模型。使用有限元软件COMSOL Multiphysics来计算和分析逆变器系统在最大功率运行时产生的电磁场在驾驶员和后排乘客不同组织中感应场的变化情况。评估了驾驶员和后排乘客的电磁暴露水平。结果表明，车辆中不同座位位置的电磁暴露水平存在显著差异。驾驶员身体的电磁暴露水平高于后排乘客，但未超过国际非电离辐射防护委员会规定的暴露限值。这一发现有效地补充了纯电动汽车电磁环境安全性评估的研究，并提高了公众意识。
