The main features of the wireless charger
1, from the theoretical point of view, wireless charging technology no harm to the human body safety, the principle of resonance wireless charging is the use of magnetic resonance, transmission in the same frequency resonance with the coil, and other devices can not accept the band, in addition, the use of wireless charging field itself is harmless to the human body. But after all, wireless charging technology is a new charging technology. Many people will worry about wireless charger based on Mai yuan technology. The technology of wireless charging will be just like the emergence of Wi-Fi and mobile antenna pole just now. In fact, technology itself is harmless.
2, wireless charging technology uses magnetic resonance to transmit electric energy in the electric field and magnetic field between the charger and the device, and the coil and capacitor form resonance between the charger and the device.
3, this system can be widely used in the future, such as the charging area for electric vehicles and the transmission of electricity for computer chips. The charging system required by this technology is only 1/150 of the current charge.
4, conversion rate has always been a problem for many people. Massachusetts Institute of Technology has shown that the loss of wireless charging technology is lower than that of wired charging technology. The conversion rate of wireless charging is a few percentage points higher than that of wired. High conversion is also a key factor in the application of wireless charger in the world. However, the wireless charging technology is also limited by the distance. The future development must solve the precise positioning of the range and the range of the magnetic field.
5. Core chip is one of the difficulties in the application of wireless charging technology. Precision radiation range control, magnetic field frequency, and other control are all realized by chip.
