1, from the theory, wireless charging technology harmless to the human body, the use of wireless charging is magnetic resonance resonance principle, only in the same frequency resonance transmission between coil, and other devices cannot accept band, in addition, wireless charging technology USES magnetic field itself is harmless to the human body.But wireless charging technology, after all, is a new type of charging technology in source of science and technology of the wireless charger, many people have concerns about wireless charging technology will as wi-fi and cell phone mast just appear, in fact, the technology itself is harmless.
2. The wireless charging technology USES magnetic resonance to transmit electrical energy between the electric field and magnetic field between the charger and the device, and the coil and capacitor can form a resonance between the charger and the device.
3. The system can be widely used in the future, such as charging areas for electric vehicles and the transmission of electricity to computer chips.The charging time required for a charging system developed by this technology is only one fiftieth of the current time.
4. The conversion rate has been a concern for many people. MIT has shown that 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 cable.High conversion is also a key factor for wireless chargers to be used globally.However, the wireless charging technology is also limited by distance. In the future, it is necessary to solve the problem of precise positioning of the range of waveband and magnetic field.
5. Core chip is one of the difficulties in the application of wireless charging technology.Precision radiation range control, magnetic field frequency, other control and so on are realized by the chip.
