How Many Meters Away from a Car Charging Pile is Radiation-Free?
1 Answers
There is no radiation at a distance of more than 2 meters from a car charging pile. Below is some information about the radiation from charging piles: 1. Safety: The electromagnetic radiation generated by electrical appliances has no significant impact on the human body (sunlight, which we encounter daily, is a form of electromagnetic radiation), as the intensity of electromagnetic radiation is limited by safety standards. Ionizing radiation has a greater impact on humans (such as the commonly referred to nuclear radiation), but it also naturally exists at certain intensities, and there is no need for concern in normal daily life. 2. Radiation Intensity: First, let's look at the national standard regulations. For low frequencies between 1~8 Hz, the permitted public exposure values are: electric field strength of 8000V/m and magnetic field strength of 500A/m. This means that any intensity below these values is considered acceptable. Taking commonly used Guoxuan lithium-powered buses and BYD K-series electric buses as examples, the measured electric field strength is 1~2V/m, and the magnetic field strength is 2~4A/m. When the vehicle speed exceeds 40km/h, the electric field strength inside the cabin is below 1A/m, and the magnetic field strength is below 0.05A/m. These values are so small that they are negligible, far lower than those of a typical smartphone.
