What are the characteristics of the wireless charger?
Dec 04, 2018

    Nowadays technology is getting more and more advanced. Wired chargers are used by us. But wireless chargers have been used by some people. At present, it is still used by a small number of people! After all, the wireless charger is just getting started, there are still many mobile phones that can't be used. Now let me introduce the characteristics of the wireless charger.

    1. The charging speed of wireless chargers has always been a concern of many people. With the advancement of technology, the loss of wireless charging is lower than that of wired charging technology. The wireless charging conversion rate is a few percentage points higher than the cable. High conversion is also a key factor in 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 precise positioning of the long-distance transmission for the band and magnetic field range.

 

    2. Wireless chargers can be widely used in the future, such as charging areas for electric vehicles and power transmission for computer chips. The charging system developed with this technology requires only one-fifth of the current charging time.

 

    3. Wireless charging technology uses magnetic resonance to transmit electrical energy between the electric field and the magnetic field between the charger and the device. The coil and capacitor form a resonance between the charger and the device.


    4. The core chip is one of the difficulties in the application of wireless charging technology. Precision radiation range control, magnetic field frequency, and other controls are all implemented by the chip.


    5.Many people worry that wireless charging will bring radiation, which is harmful to the human body. In fact, wireless charging technology is safe for human body. The resonant principle used by wireless chargers is magnetic field resonance, which is only transmitted between coils that resonate at the same frequency. While other devices cannot accept the band, in addition, the magnetic field used by the wireless charging technology itself is harmless to the human body.
