The development trend of wireless charging technology
Information from:internet Published on:2022-03-02
Wireless charging technology has long been everywhere in our life. Wireless charging is very convenient. It can be charged directly on the charger, because it is welcomed by the majority of netizens. Of course, the emergence of wireless charging does not affect wired charging, because not every product can be charged wirelessly. Let's learn about the development trend of wireless charging technology? Compared with wired charging, the biggest advantage of wireless charging technology is that it can provide better spatial freedom. The first generation of magnetic induction wireless charging has a small degree of freedom, which limits the user's use scenario. The second generation of magnetic resonance wireless charging technology came into being. Compared with the first generation of magnetic induction wireless charging technology, the core of magnetic resonance wireless charging technology is to control the energy path more smoothly through dual resonators. The principle of wireless charging technology is to use the high-frequency constant amplitude alternating magnetic field generator to generate a 6.78mhz resonant magnetic field, which increases the effective charging distance from 5mm to 5cm of magnetic induction wireless charging technology, and improves the freedom of wireless charging to a certain extent. Another electromagnetic wave wireless charging technology may really meet the ideal wireless charging scenario. It uses high-frequency electromagnetic waves for wireless charging. Like wireless internet access, users can connect Wi Fi signals 5 to 10 meters apart and charge anytime, anywhere. Although the University of Washington has successfully developed a technology to charge hardware devices using Wi Fi networks, the technology does not have a commercial foundation. The transmission power of common household wireless routers is between 50MW and 100MW. If you charge your mobile phone, you need to increase the transmission power of the router by 2000 times. Such strong electromagnetic waves will have a potential impact on human health. Therefore, the prospect of technology development is not clear.
