Are electric cars really radioactive? Does it matter to us?

With the development of economy and decline of air quality, new energy vehicles become the inevitable trend of future development. With the investment of the auto enterprises and national policy guidance, the electric car has become the trend of the market. More and more people begin to choose energy conservation and environmental protection of the electric car as a vehicle of their own.

Last year, China's new energy automobile sales to 777000, the number of production and sales this year are also expected to break through the million mark, although the new energy vehicles to maintain the trend of rapid development, but the distance with the industry planning issued by the state, by 2020 China's new energy vehicle sales to 2 million vehicles a year and a certain distance. In addition, about the electric car is not environmental protection, new car battery to be rushed to the 100% cycle three times, rainy days can't charge...This rumor is also restricts the promotion and development of new energy vehicles in the market.

According to the authority according to a survey, 73% of people think that there is electromagnetic radiation, electric cars around 37% of people think that the radiation may even affect human health. Click on online rumors abound about electric cars, when the new energy automotive policies, subsidies and infrastructure construction after the continuously perfect, but such rumors about "electromagnetic radiation" as a potential obstacle affecting the popularization and growing new energy vehicles.

The electric car actually have radiation?

Radiation to ask the electric car? The answer is: yes! In fact, the electromagnetic radiation is everywhere in our life, the earth itself is a large magnetic field, electric field and magnetic field generates electromagnetic wave interaction changes, electromagnetic energy transmission process called electromagnetic radiation in the air. The human body to a certain range of electromagnetic radiation can absorb, so not all electromagnetic radiation is harmful to human body.

Start with the electronic products around us, as an lateral comparison reference to electric cars.According to an authoritative organization, in daily life, laptop of electromagnetic radiation is about 10.69 mu T, mobile phone radiation is 18.37 mu T when watching video, TV is 2 mu T, LCD TV set to 0 mu T, hair dryer back 9.32 mu T, patch panel is 2.97 mu T socket, Siemens refrigerators is 0 mu T, rice cooker of 0 mu T, microwave oven panel is 19.78 mu T positive radiation (extraordinary).From the test results, each instrument measuring results and product brand, the calculation time, place, have a certain relationship, but the numerical approximately.

For electric vehicles, with ordinary common Jianghuai iEV4 and BYD e6 model as an example, the electromagnetic radiation test results of charging pile is: Jianghuai iEV4 form a complete set of charging pile of electromagnetic radiation of 4.78 mu T at work, spear and car battery charging socket of electromagnetic radiation of 5.52 mu T, although are higher than the average of the e6 car, but also within the WHO considered safe, and is reduced to 0 in 20 centimeters away.

Car of radiation to human body, in fact, most of the time in the process of the car. Calculation results show that the average iEV4 pure electric vehicle test results is 0.597 mu T, lower than the e6 2.95 mu T level of high power, however, the e6 no matter top speed or range all over Jianghuai iEV4 greatly.

Test results also confirmed: the greater the power of the electric car, the greater the electromagnetic radiation does. However, neither the e6 2.95 mu T, or 0.597 mu of Jianghuai iEV4 T, were significantly lower than the international health organization (WHO) and China, Sweden, 100 mu T electromagnetic radiation alert criteria.

The impact on the us what size is it?

Such numerical for we don't know much about physics is not so easy to see what, back and forth to see everyone in life will come into contact with the cell phone radiation: see WeChat electromagnetic radiation 0.20 mu T, send WeChat messages when the electromagnetic radiation of 0.45 mu T, while playing the video of electromagnetic radiation is as high as 19.00 mu T, which is about 6.44 times that of BYD e6 electric car is 31.82 times of Jianghuai iEV4 pure electric vehicles! Thus, mobile phones are small, because of the emission function, so the radiation far better than "big" of pure electric vehicles!

In fact, the real cause harm to human body is mainly the ionizing radiation. Ionizing radiation is smaller than 100 nm wavelength of electromagnetic radiation, it is a short wavelength, high frequency, high energy ray, the body is exposed to the rays can kill a few minutes, and produce ionization radiation is to have a huge amount of energy released, the premise of energy and new energy vehicles produced by the far less than standard.

In daily life, ordinary people is difficult to have the opportunity to come into contact with the "radiation", and as for the medical radiation is also in operation, the completion of the specified process under the influence is not severe.

As for cell phones, microwave oven, hair dryer, such as "radiation", not "ionizing radiation" category, they belong to the "electromagnetic radiation" or "non-ionizing radiation", to human body damage .According to the United Nations world health organisation standards about the safety of electromagnetic radiation, electromagnetic field, the electric field radiation safety standard is 5000 v/m, magnetic radiation safety standards for 100 mu T. That is to say, household appliances as long as less than 5000 v/m and 100 mu terabytes of data, the radiation values are within the scope of security.

Tests have shown that electric radiation is far from a laptop computer radiation. Furthermore, new energy automobile manufacturing process have also been considered battery radiation problem, the battery pack for new energy vehicles and so on all the relevant protective measures. To make the potential of pure electric vehicles, for example, the main drive radiation of 0.88 mu T, the passenger is 0.85 mu T, from left to right to the back seat were 0.47 mu, 0.43 mu mu T T and 0.43 T, together all parts of the car electric field radiation is less than 5 v/m, less than 1 mu T magnetic field radiation, far more than cell phones and laptop computers and other daily equipment of electromagnetic radiation is much lower. Others, such as tesla, BMW I series, lexus CT series of electromagnetic radiation are also belong to the safe range.

Edit comments: when the policy of new energy vehicles is gradually perfect, infrastructure construction is advancing, the electric car "electromagnetic radiation" such rumors should not become a stumbling block for the further development of new energy vehicles again!
