After a few days of suspense-like copywriting preheating, Xiaomi finally solved the "mystery" of this new technology! 65438+1around the morning of October 29th 10, Xiaomi officially launched a brand-new "black technology", Xiaomi's first self-developed charging system! Lei Jun marveled: Lei Jun: Like a science fiction movie!
It can be charged at a distance of 5 watts within several meters.
It is true that technological innovation has never stopped exploring since the birth of mankind, and every epoch-making technological innovation is explored in the "no man's land" of science and technology.
Have you ever imagined the future charging method? Once you enter the house, you don't need any charging cable and charging base, and your mobile phone can be charged freely at a long distance no matter where you are?
According to Xiaomi's official Weibo account, after numerous explorations and attempts, we have successfully developed the first set of remote charging system with 17 technical patents. Take your mobile phone into the living room, you can charge it from a distance, and it doesn't matter if there are foreign objects while playing. Multiple devices can also charge 5 watts at the same time.
In the latest Weibo, the person in charge of Xiaomi described the charging technology seen from a distance as a science fiction movie.
On the mobile phone side, Xiaomi also developed the miniaturization design of antenna array, internal beacon antenna and receiving antenna array. Beacon antenna broadcasts the position information in the space field with low power consumption, and the receiving antenna array composed of 14 antenna converts the millimeter wave signal sent by the charging pile into electric energy through the rectifier circuit, thus realizing the long-distance sci-fi charging experience.
According to Xiaomi, the charging technology independently developed by Xiaomi has realized the long-distance charging of 5 watts for a single device within a radius of several meters. Moreover, multiple devices can be charged at the same time (each device supports 5 watts), even if there are foreign objects, the charging efficiency will not be reduced.
Everyone knows that Xiaomi is going to "make trouble" on the morning of June 29, 65438, and the prophet's friends can't sit still. Lenovo took the lead in "kicking the pavilion" to promote black technology.
Just after 8: 00 in the morning, Magic Brother Gold, whose real name is certified as "General Manager of Lenovo China Mobile Phone Business Department", issued a Weibo statement: "Motorola's charging distance from a distance can be much longer than the current contact charging based on Qi technology, and it can charge multiple mobile phones at the same time, with higher freedom and safety performance, which is a real wireless charging. Everyone said, do you want to add this black technology to the future Motorola edge series? "
But from the video, Motorola's space charging equipment is actually not "free" and needs to be placed on a fixed base without shelter.
Will the future really get rid of the shackles of wires?
In recent years, the rapid development of science and technology has made a major breakthrough in the research of wireless power transmission, making it possible to charge electronic equipment wirelessly.
Since the Tesla coil was invented by American scientist Nikolai Godzilla at the end of19th century, human beings have been trying to acquire it from a distance. Up to now, the technology has realized wireless charging, and even the power has reached more than 80W. However, the research and development of real space charging is still difficult and has not yet been commercialized.
On the road of wireless charging, Xiaomi has always been an activist, from 40 watts in March 2020, 50 watts in Xiaomi 10 Supreme Commemorative Edition, to 80 watts in 10. In just over half a year, the wireless charging power of Li and Xiaomi has doubled. In June 5438 +2020 10, Xiaomi officially announced the 80-watt wireless secondary charging technology. According to the data released by Xiaomi, the 80W wireless second charge of Xiaomi, the 4000mAh battery can be charged half in 8 minutes, and it can be fully charged in 19 minutes, which is very close to the fastest wired fast charge on the market.
Now, with the release of the remote charging technology independently developed by Xiaomi, will this be a revolutionary breakthrough in the history of charging technology? Will the future living room fully enter the wireless era?
In Xiaomi's view, this is a revolutionary innovation of wireless charging and a bold attempt to make the whole house wireless. This is not science fiction, but technology.
According to Lei Jun, in the near future, Xiaomi can also charge wearable devices such as smart watches and bracelets through the air. The living room in the future, including small smart home products such as speakers and desk lamps, can realize wireless power supply design, get rid of wired constraints and truly realize wireless living room.
At present, the air charging system independently developed by Xiaomi has a long way to go. First of all, it has not been mass-produced. More importantly, after all, only 5W charging power can be realized now. At present, 4000mAh battery has become the standard of smart phones. To make this charging system full, the waiting time will be tiring.
However, from a realistic point of view, this innovation of Xiaomi is exciting enough. The pleasure brought by technology is as smooth as silk. Even if the charging speed is slow enough, charging with fragmented time can keep the phone "quiet". Secondly, in the crowded office and business environment, if such a remote charging device can be installed, it can meet the needs of most people for wireless charging lines at the same time. With the first person to eat crabs, I believe more friends will follow up the new ones.
