1. Theoretically, wireless charging technology is harmless to human body. The resonance principle of wireless charging is magnetic resonance, which only transmits between coils that resonate at the same frequency, while other devices cannot accept the band. However, wireless charging technology is a new kind of charging technology. In the case of maiyuan's wireless charger, many people will worry that wireless charging technology will be as harmless as wi-fi and mobile phone masts when they first appeared.
2. Wireless charging technology USES magnetic resonance to transmit electricity in the electric and magnetic fields between the charger and the device, while coils and capacitors resonate between the charger and the device.
3. The system could be widely used in the future, such as charging areas for electric cars and power transmission for computer chips. A charging system based on this technology would require only one-fiftieth of the current time.
4. Conversion rate has always been a concern of many people. According to the research conducted by MIT, the loss of wireless charging technology is lower than that of wired charging technology. The conversion rate of wireless charging is several percentage points higher than that of wired charging. High conversion is also a key factor for wireless chargers to be used globally. However, wireless charging technology is also limited by distance. In the future development, it is necessary to solve the problem of accurate positioning of band and magnetic field range by long-distance transmission.
5. Core chip is one of the difficulties in the application of wireless charging technology in products. Precise radiation range control, magnetic field frequency size, other controls are implemented by the chip.
