1. Trams and charging piles are both “electromagnetic radiation”
Whenever radiation is mentioned, everyone will naturally think of mobile phones, computers, microwave ovens, etc., and equate them with X-rays in hospital films and CT scans, believing that they are radioactive and will have a negative impact on the health of users. The popularity of electric travel today has intensified the concerns of some car owners: “Every time I drive or go to a charging station, I am always afraid of radiation.”
In fact, there is a big misunderstanding in this. The reason for the misunderstanding is that everyone does not distinguish between “ionizing radiation” and “electromagnetic radiation”. The nuclear radiation everyone talks about refers to “ionizing radiation”, which may cause cancer or damage the DNA structure. Household appliances, communication equipment, electric motors, etc. are “electromagnetic radiation”. It can be said that any charged object has “electromagnetic radiation”. Therefore, the radiation generated by electric vehicles and charging piles is “electromagnetic radiation” rather than “ionizing radiation.”
2. Below warning standards and can be used with confidence
Of course, this does not mean that “electromagnetic radiation” is harmless. When the intensity of “electromagnetic radiation” exceeds a certain standard, or even reaches “electromagnetic radiation pollution”, it will also produce negative effects and endanger human health.
The currently used national standard magnetic field radiation safety standard limit is set at 100μT, and the electric field radiation safety standard is 5000V/m. According to tests by professional institutions, the magnetic field radiation in the front row of new energy vehicles is generally 0.8-1.0μT, and the rear row is 0.3-0.5μT. The electric field radiation in each part of the car is less than 5V/m, which fully meets the requirements of national standards and is even lower than some Fuel vehicle.
When the charging pile is working, the electromagnetic radiation is 4.78μT, and the electromagnetic radiation from the gun head and charging socket is 5.52μT. Although the radiation value is slightly higher than the average value in the car, it is far lower than the electromagnetic radiation warning standard of 100μT, and when charging , keep a distance of more than 20 cm from the charging pile, and the radiation will be reduced to 0.
As for the problem mentioned on the Internet that long-term driving of electric vehicles will cause hair loss, some experts pointed out that this may be related to factors such as long-term driving, staying up late, and mental stress, but may not be directly related to driving new energy vehicles.
3. Not recommended: stay in the car while charging
Although the risk of “radiation” has been ruled out, it is still not recommended that people stay in the car while charging. The reason is also very simple. Although my country’s new energy vehicle and charging pile technology is very mature at present, it is limited by battery characteristics and cannot completely eliminate the possibility of thermal runaway. In addition, when the vehicle is charging, turning on the air conditioner, using in-car entertainment equipment, etc. will further extend the charging waiting time and reduce the charging efficiency.
