Today to share with you the mobile phone wireless charging people have no radiation knowledge, which will also explain the mobile phone wireless charging to the mobile phone, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>The harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses magnetismThe "resonance" principle allows the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
has little effect on human body; Wireless charging uses the principle of electromagnetic induction, which operates at a very low frequency and does little harm. If you are still worried, you can choose a shielded scheme.
Taking 1000mAh capacity lithium battery as an example, the radiation of wireless charger is calculated. 50% charging capacity is about 7~8Wh. If it requires about two hours to fill, the maximum charging power is at leastTo reach 1W (GSM900 mobile phone maximum power of about 2W); Since the wireless charging method of the phone is to place the phone above the charger rather than inside, the radiation leakage rate can be not small.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is just like the Wi-Fi, mobile phones, TVS and other electronic products we usually use, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless chargingA question.
Charging with wireless charger, is the radiation big? There must be, should belong to the range of electromagnetic radiation, a long time in the electromagnetic radiation has an impact on the human body, the radiation intensity also depends on the emission power and radiation range to determine.
1, First answer no: Yes. The working power of the wireless charger is larger than that of the mobile phone, and the electromagnetic field energy radiated by the wireless charger is larger than that of the mobile phone.
2, many wireless chargers on the market do not indicate the radiation value, forThe electromagnetic radiation standard for wireless chargers has not yet been introduced. According to the Regulations on Electromagnetic Radiation Protection, the average specific absorption rate (SAR) of the whole body of ordinary users should be less than 0.02W/kg for any consecutive 6 minutes within 1 day and 24 hours. 3, the Ministry of Telecommunications Research Institute Tel laboratory director He Guili said that wireless chargers have radiation is inevitable, but since it has been listed, it means that it must meet international standards, will not cause harm to the human body. "As long as the wireless charger is done according to the technical specifications, it will not have a radiation hazard to the human body." He Guili said. This shows that the Internet rumors are not true.
4, all mobile phone radiation parameters listed in Samsung Mainland comply with the relevant national regulations, please rest assured to use.
3, the harm is relatively small can be ignored, wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
4, wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
5, in order to effectively reduce the adverse effects of electromagnetic radiation on health. For mobile phones: under normal circumstances, it will not harm the mobile phone, and the working frequency of wireless charging is now below 1M, so the opponent
