Wireless charging creates infinite possibilities

The definition of wireless charging is to connect the terminal equipment to be charged without the traditional charging power line, and transfer the electric energy magically by using the magnetic field generated between the coils. The equipment with this function is called wireless charger or wireless charging board.

With the introduction of more and more mobile devices, the need for frequent charging has become a fast way of life for people. Mobile phones and charging treasures are standard for people to go out, and wireless chargers have begun to flow into the market in large numbers. People are moving towards the era of wireless charging. Next, let's talk about why this wireless charging can become the current trend.

1. Wireless represents advanced and convenient

If you review mobile phones, laptops, wireless headsets, wireless speakers These products that change people's lifestyle and habits, you would like to believe that wireless represents advanced and convenient.

When it comes to wireless charging of mobile phones, it makes better use of people's fragmented time - charging as you take it, avoiding the trouble of frequent plugging and plugging, as well as the damage of data lines. With the consensus of canceling the 3.5mm headphone interface, wireless charging can solve the problem of not paying attention to both listening and charging.

2. Wireless charging represents the future

It's like when Android phones first appeared, they were slow to use, but now they have completely changed the world. New things representing advanced productivity are always unstable at birth, but full of imagination. Although the wireless chargers on the market generally have the problems of low power, slow charging and distance limitation, but with the development of science and technology, human wisdom is infinite, and some high-power wireless chargers on the market also began to flow into the market. The high-power wireless fast charging of 15W or even 20W, such as Xiaomi Samsung, has been launched on the market, and has some good reviews. This means that the wireless charger will continue to progress, and gradually move towards the mainstream market in the future, becoming the just need of people's charging.

Judging from the current situation, although the trend of wireless charging can't reach people's ideal state, the ideal scenario of wireless charging in the future is senseless charging - charging unconsciously, such as Wi Fi charging. Through the microwave resonance mode, microwave is used as the energy transmission signal. After receiving the energy wave, the receiver will return it to the available DC power through the resonance circuit and rectifier circuit. This way is equivalent to our common Wi Fi wireless network. Both the sender and the receiver have a special antenna. The difference is that this time, it's not a signal but electricity.

Because the energy of microwave resonance mode is divergent, its energy utilization efficiency is very low, but it is superior to high flexibility in position. For example, Intel's solution is to design ultrabook as the transmitter of wireless charging and mobile phone as the receiver. When you go to work, as long as your cell phone is next to the ultrabook, you can recharge it unconsciously and continuously. The intuitive experience is that the power of the mobile phone never fails.

If microwave resonance mode can break through the technical bottleneck, achieve popularization at the sending end, or achieve substantial improvement in charging efficiency, then the future mobile phone will be charging all the time, and no one will care about the endurance.
