1, the principle of radio waves is to convert environmental electromagnetic waves into current and transmit current through the circuit. The transmission distance of this wireless charging method is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. However, because of the low conversion efficiency, if you use this method, the charging time will be longer.
2, first of all, OPPO Reno Ace is supported in OPPO brandOne of the mobile phones with wireless charging function. The phone uses VOOC flash charging technology to support wired charging speeds of up to 65W, while wireless charging supports power of up to 10W, which can meet the charging needs of daily use. Secondly, the OPPO Find X2 Pro is also a mobile phone that supports wireless charging.
3, the principle of wireless charging is actually very simple, in fact, electromagnetic induction, a changing magnetic field can produce an electric field, and a changing electric field can produce a magnetic field. In high school textbooks, Faraday has long taught us the truth of "electromagnetic mutuality". Charging dock and cell phoneEach has a coil, the one in the charging dock is called the main coil, and the one in the phone is called the secondary coil.
4, using the principle of magnetic resonance, arranged in the magnetic field of the same vibration frequency of the coil, each other to transfer electrical energy. This wireless charging technology is superior to electromagnetic induction wireless charging technology, which not only extends the transmission distance, but also does not require the position of the coil to be completely matched. In addition to the above two wireless charging technologies, there are also electric field coupling wireless charging technology and microwave resonance wireless charging technology. Although wireless charging technology has some years of development, many problems restrict its universal application.
African market, the reasons are as follows: Africa's demographic dividend and low labor cost advantages can provide more business opportunities. The European market and the South American market have more perfect commercial facilities, and the business opportunities are basically saturated. Consumer demand in Africa is also increasing, especially for consumer goods and services. Consumer demand in Europe and South America is relatively stable.
Yes. According to the inquiry of BYD's official website, BYD Seal's vehicle is equipped with BYD's self-developed DiLink intelligent network connected vehicle system, which can support 5G network and wireless charging. Byd Auto is ChinaA mainland car manufacturer listed on the Hong Kong Stock Exchange. The cars are sold in Africa, South America and the Middle East, with plans to enter the European and Israeli markets.
Is wireless charging a pseudo demand? Market data explains everything. The premise of three-body wireless charging is that energy is cheap, controlled nuclear fusion allows all mankind to achieve energy freedom, and it is not the wireless charging technology itself. Indeed, many wireless charging bases currently have small area and low power. Of course, the 20w wireless charging of the Xiaomi 9 has been faster than the 18w wired charging of the QC0 protocol, but the area is still relatively small.
At present, the average daily passenger flow of the market is about 100,000 people, and mobile phone products flow from here to all over the country, and radiate Asia, Africa, the Near East, the Middle East countries and exported to North America, South America, Europe, Oceania countries and regions. Merchants are basically wholesale, very little retail. Huaqiangbei Electronic Market Overview There are about 50 major electronic markets in Huaqiangbei Commercial Street, mostly in the mobile phone industry.
The prospect is very objective. Wireless chargingThe advantage of prospect is: dare to break down the practice of wireless charging prospect . The exploration of building a shared charging ecology. At present, wireless charging prospect , Gudian can provide 4cm space charging, 10-30cm short distance electronic device charging, half a meter space charging and range space charging scheme. Adhere to the integrity of the innovative team.
But the advantages of wireless charging are also very obvious. Since there is no need to plug and unplug the charging gun, the convenience of charging is significantly improved, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
The coil in the loosely coupled system can have a larger distance, but the power transmission efficiency is low, and the electromagnetic radiation is high. Electromagnetic induction has many advantages, such as simple circuit schemes and better cost effectiveness. The main disadvantages include the limited charging distance and the need for precise alignment between the transmitter and receiver. Magnetic resonance (resonance induced coupling) is a near-field method that uses resonance phenomena to transmit electrical energy wirelessly in a certain spaceThe principle is the same as electromagnetic induction.

Apple wireless charging concept stocks are: Hengdian East Magnetic (002056) : Hengdian East Magnetic said on the interactive platform on September 6, 2017 that the company currently provides wireless charging disks to Apple.
1, wireless charging is basically a gimmick. Not much practical use value. Not as efficient as solar cells. 2, Samsung is developing a new wireless charging technology, is expected to solve the distance limit problem, is expected to be launched in the second half of 2014, for the mobile phone wireless charging market to bring new possibilities. Overall, although there are challenges in the wireless charging market, with technological progress and manufacturer cooperationThe strengthening of its prospects can be expected. 3, I think the current domestic market has a variety of wireless chargers, but there are many problems have not been solved, such as the problem of compatibility with mobile phones, interface limitations, conversion efficiency. If all these problems are solved, wireless charging mobile power can be welcomed by consumers.
4, Momis wireless charging treasure power output: wired 10W and wireless 5W power input: 10W Advantages: high-definition LED power display Recommended reasons: Momis wireless charging treasure body shell is black high-endABS plastic is made with electroplated bright silver frame, the main surface of the charging treasure uses bright surface design, the overall design will be more beautiful.
5, therefore, such a large demand, I think the prospect of mobile power should be good. Because with the continuous introduction of high-performance and high-configuration mobile phones, tablets and digital products, the built-in battery has become more and more unable to keep up with the power consumption of the hardware, so the mobile power has become the best partner for battery life at present, so the prospect is still more promising.
