Biological experimental study on cumulative effect of vehicle electromagnetic radiation

compared with power frequency magnetic field or mobile phone, electric vehicles are equipped with more and more high-voltage components, more and more electronic components, and their frequency, waveform and modulation mode are more flexible, which may make the electromagnetic exposure scene of passengers in the vehicle more complex. With the acceleration of the comprehensive electrification trend of public transport, people are exposed to electric vehicles more and more frequently, and the time is also gradually increasing. Whether the cumulative effect of vehicle electromagnetic radiation has an impact on occupant health is a matter of general concern to consumers. At present, there is still a lack of relevant research and standards on the cumulative effect of vehicle electromagnetic radiation at home and abroad. In this paper, a pure electric vehicle is taken as the test object, and the test mice are taken as an example to verify whether the cumulative effect of vehicle electromagnetic radiation has an impact on the body weight and blood immune cells of mice. The results showed that there were significant gender differences in body weight. However, the test time needs to be further increased to judge whether the cumulative effect causes the impact.
