The Era of Wireless Charging is Coming

Remember the physics lesson in junior high school that was the most headache for electromagnetism who always wanted to wander? The rule of the left and right is that other people besides Xueba are really unable to cope with it. Although electromagnetics was a big problem for us during our student years, nowadays, it has brought many conveniences to our lives. For example, wireless charging has become popular in recent years. Did you know that from the discovery of electromagnetic induction to wireless charging, has humans walked for more than 180 years?

The 19th century was an important stage in the development of human science and technology. The famous volts, Fourier, Ohm, Gaussian, Joule, Maxwell, Faraday and other people in physics were from that era. Among them, Michael Faraday was particularly inspirational, not only self-taught, Moreover, the law of electromagnetic induction was discovered. This discovery explained the conversion between electricity and magnetism, and laid a solid foundation for the future explosion of electromagnetics.

However, after Faraday discovered the law of electromagnetic induction in 1831, in terms of industry and demand at that time, the electromagnetic induction disease did not bring significant changes to people's lives. It was not until the following decades that generators, induction cookers and other products appeared. For ordinary people, the real impact of electromagnetic induction on our lives is after the popularization of wireless technology. This is the second half of the 20th century. Electromagnetic + wireless technology has got rid of the previous constraints, and people have the opportunity to be unrestricted. Use the latest technology.

The wireless charging of smartphones now emerging is the most direct manifestation of electromagnetic induction, using the metal coil in the charging base, which can generate a magnetic field when connected to a current, and the smartphones that support wireless charging also have metal coils that receive magnetic fields to generate The current realizes the charging process.

From the discovery of the law of electromagnetic induction to wireless charging, humans have been walking for more than 180 years. This process is so long, not because human development is too slow, but to continuously solve various technical limitations, materials, costs, safety, and other restrictions in the middle, which affects the popularity of wireless charging technology.

Nowadays, many companies in the market have invested in the research and development of wireless charging technology, such as the well-known domestic and foreign brands such as Belkin, mophine, and Beth. There are also wireless charging technology applied to the equipment that it can carry, such as Philips, which is a Hong Kong brand specializing in the development and production of smart car air purifiers with a registered capital of 51 million yuan. Changsha, Hunan set up a research and development production base. Relying on the influence of Hong Kong brands and advanced foreign technology, it successfully developed the first in-vehicle smart air purifier equipped with mobile phone wireless fast charging technology in 2018 and signed a contract with the Chinese film and television superstar "Jiao Enjun" The company's brand ambassador has also reached a strategic cooperation agreement with CCTV1.

An important reason why wireless charging is not yet popular is that ordinary people have misunderstandings that wireless charging has a large radiation. In fact, manufacturers of wireless charging have also taken this into consideration. The general wireless charging has a built-in magnetic isolation sheet, which can effectively shield electromagnetic Radiation to prevent electromagnetic radiation damage.

After solving the material and cost constraints, wireless charging technology can be said to be promising, and large devices such as cars have begun to support wireless charging, but the most impact on ordinary people is the mobile mid-range wireless charging machine. In 2017, Apple's iPhone X and iPhone 8 also officially supported wireless charging, which means that more mobile phone brands will choose to support wireless charging, and the wireless charging industry will usher in a broader market prospect.

From the perspective of the development process of wireless charging technology in the industry, wireless charging technology will develop in the direction of higher power, faster charging speed and safer in the future. At the same time, the cost will continue to decrease. According to the current trend, we can even see that wireless charging completely replaces wired charging in the future. I hope this process is not far away.
