What is a wireless charger? What are its characteristics?

Wireless charger refers to the charger that does not use the traditional charging power line to connect to the terminal equipment that needs charging. It adopts the latest wireless charging technology. By using the alternating magnetic field generated between coils to transmit electric energy, inductive coupling technology will become a bridge between charging base stations and equipment.

Characteristics

1. In theory, wireless charging technology is harmless to human safety. The resonance principle of wireless charging is magnetic resonance, which is transmitted only between coils resonating at the same frequency, while other devices cannot accept the wave band. In addition, the magnetic field used by wireless charging technology itself is harmless to human body. However, wireless charging technology is a new charging technology after all. For the wireless charger of maiyuan technology, many people will worry that the wireless charging technology will be just like the emergence of Wi Fi and mobile phone antenna mast. In fact, the technology itself is harmless.

2. Wireless charging technology uses magnetic resonance to transmit electric energy in the electric and magnetic field between the charger and the equipment, and coils and capacitors form resonance between the charger and the equipment.

3. This system can be widely used in the future, such as charging area for electric vehicles and power transmission for computer chips. The charging time of the charging system developed with this technology is only one fiftieth of the current one.

4. The conversion rate has always been a concern of many people. MIT research shows 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 wired charging. High conversion is also a key factor for the global application of wireless chargers. However, wireless charging technology is also limited by distance. In the future, it is necessary to solve the problem of accurate positioning of long-distance transmission in terms of band and magnetic field range.
