Wireless charger has become a common device in our daily life. Many office workers usually put their mobile phone on the wireless charger. Although it's a little slower, it has enough time to fill it up for eight hours.

As long as the mobile phone is placed on the wireless charging board, the mobile phone begins to charge wirelessly, which is a common operation. Yes, wireless charging frees us from the shackles of cell phone charging wires, but it only helps the cell phone get rid of the shackles of charging wires. There is still a small tail on the bottom of the charger, and we even have to cling to it.

What about our ideal wireless charging? In your spare time, walk into a cafe and your cell phone can be charged wirelessly. Of course, if we have smart watches or Bluetooth headphones, they will also be charged. We can play with mobile phones in various postures and enjoy this rare leisure time.

Full ideal in front of the reality of bone sense, can only reluctantly put down arrogance, the world can not do without compromise. Of course, this is only our ideal wireless charging, but wireless charging has been used in a small amount in all kinds of electronic equipment, in addition to mobile phones, as well as electric toothbrushes, electric shavers, smart watch bracelets, and electric cars under study. This also means that wireless charging will become a very common way of charging in life. The real wireless era is coming, and human wisdom is immeasurable, which will eventually become reality.

Let's look at the principles behind this amazing wireless charging device.

The most common method is to use Faraday's law of electromagnetic induction. Using this law, we place a coil (closed circuit) at the transmitter and receiver, which electrifies the transmitter and generates magnetic field through current. When the coil at the receiving end enters the magnetic field, it generates current, thus realizing the transfer of electricity from one end to the other without passing through the wire. Of course, not only electromagnetic induction, but also resonance circuit and magnetic field coupling are used.

The QI standard of Wireless Charging Alliance (WPC) is based on electromagnetic induction. Most smartphones and wearing devices use this standard nowadays. YMP brand wireless charger also strictly implements Qi charging standard of WPCV1.2. It specializes in developing and producing wireless charging products for mobile communication devices such as mobile phones and tablets.

At present, there are vehicle-mounted wireless charging, portable wireless chargers and desktop mosaic wireless charging, and according to this universal law of electromagnetic induction principle, you can customize different wireless charging schemes, according to power, use and so on, you can choose the appropriate scheme. There are professional teams and reasonable prices for your reference.

The second is the principle of magnetic resonance. In fact, it is based on electromagnetic induction. Resonance and magnetic coupling are also used. The difference is that the working frequency of transmitter and receiver is at the resonance point, and the signal frequency is the same, so as to achieve resonance. By coupling the magnetic field at the resonance point, the transmission efficiency can be improved and the transmission distance can be greatly increased.

In addition to the above two, there are WiFi wireless charging technology, which can be charged by router, and the distance is up to 10 meters. And the ultrasonic wireless charging technology, wearing a special wireless charging set, can be in five meters to the mobile phone wireless charging.

There are so many principles of wireless charging, which may be used in future wireless life. However, from the current point of view, the QI charging standard using the law of electromagnetic induction is still the mainstream standard in the market. Although it has various inconveniences, short transmission distance and low power, after a period of development, it charges. Electrical power has also been gradually increased, such as Huawei and Millet, which have increased power to 15W and 20W, which also indicates that wireless charging is no longer a very limited function.

Although the technical principles and implementation methods are not complicated, wireless charging has not yet become the standard of mobile phones. Most Android phones on the market still do not have the function of automatically receiving QI charging, but it is very convenient to realize wireless charging by adding a QI charging receiver. Yixin Chuangyan can also provide this wireless charging scheme, and there are corresponding wireless charging receiving protective jackets that can be customized, so that your mobile phone can be closer to wireless charging.

Generally speaking, we are still far from the real fantasy of wireless charging, but the complete realization of wireless charging is sooner or later, we have reason to believe that wireless charging will bring unlimited convenience to future life, and it is very worthy of our attention and support.
