Power of Electric Vehicle Charging Stations?
1 Answers
Different vehicle models require charging stations with varying power outputs, typically either 160 or 240. Below is a partial introduction regarding the radiation from charging stations: Safety: The electromagnetic radiation generated by electrical devices has negligible impact on the human body (sunlight, which humans encounter daily, is a form of electromagnetic radiation), as the intensity of electromagnetic radiation is regulated by safety standards. Ionizing radiation has a more significant effect on humans (such as what is commonly referred to as nuclear radiation), but it also naturally exists at certain intensities, and there is no need for concern in normal daily life. Radiation Intensity: First, consider the national standard regulations, which specify permissible public exposure values for low frequencies between 1~8 Hz as follows: electric field strength of 8000 V/m and magnetic field strength of 500 A/m. This means that any intensity below these levels is considered compliant. Taking commonly used examples such as the Guoxuan lithium-powered electric buses and BYD K-series electric buses, the measured electric field strength is 1~2 V/m, and the magnetic field strength is 2~4 A/m. When the vehicle speed exceeds 40 km/h, the electric field strength inside the cabin is below 1 A/m, and the magnetic field strength is below 0.05 A/m. These values are so minimal that they can be considered negligible, far lower than those emitted by a typical smartphone.
