Does Driving a New Energy Vehicle Have Radiation?
2 Answers
Driving a new energy vehicle does have radiation, but it is extremely minimal and negligible. The radiation generated by new energy vehicles is expressed as electromagnetic radiation, which is a type of non-ionizing radiation. However, the electromagnetic levels of new energy vehicles are much lower than those of common household appliances, with radiation values even lower than those of an ordinary laptop. Taking a typical new energy vehicle as an example, tests on the electromagnetic field radiation of charging piles show that the electromagnetic radiation during operation is approximately 4 to 5 teslas, while the radiation at the charging gun head and the vehicle's charging port is 5 to 6 teslas. During driving, the measured results indicate that the average radiation values are generally below 4 teslas. The radiation levels are related to parameters such as battery capacity and driving range. The World Health Organization (WHO) considers the safety standard for magnetic field radiation to be 100 teslas. The radiation experienced while driving a new energy vehicle is far below the WHO's alert threshold. Therefore, although driving a new energy vehicle involves radiation, it does not pose any harm to human health.
As someone with some knowledge of electromagnetism, I find that the issue of radiation from new energy vehicles is often misunderstood. The magnetic field strength of the motor is about one-thousandth of that during a phone call, and driving for half an hour exposes you to less radiation than using a microwave once. Look at the data from the State Grid—the highest radiation level inside the car is only 0.3 microteslas, while riding the subway exposes you to over 1 microtesla. The key is that the electromagnetic shielding technology for the battery is particularly effective. Last year, I took apart a friend's car and saw that the battery pack was tightly wrapped in three layers of alloy. What you really need to be careful about is the radiation from under the car—remember to buy an undercarriage armor film to filter electromagnetic waves for added safety. Electric vehicles have one less major radiation source compared to old gasoline cars—the engine ignition coil. This data point is often overlooked in reports but is crucial.
