Today to share with you the Ministry of Industry and Information Technology to seek wireless fast charging knowledge, which will also explain the Ministry of Industry and Information Technology wireless charging, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Obviously not, because you have to put a wireless charging dock on the desk with a cable to charge it. In addition, 50W wireless charging power is the upper limit of this regulation, can be introduced, is still a question mark. After all want toTo limit it to less than 50W, experts must enumerate some cases, and what harm will be done once it is exceeded. Because once the regulations are introduced, it means that China will not be able to research and develop wireless charging above 50W in the future. In October, Apple released support for 15W MagSafe magnetic wireless charging technology. Domestic mobile phone manufacturers have done a better job in high-power fast charging, and some brands of smartphones such as Huawei, OPPO, and Xiaomi that are currently on sale have achieved 50W wireless charging, and there is a further trend toward high-power development. Except for the rapid penetration on the phoneIn addition, wireless charging is also accelerating the expansion of notebooks, watches, headphones and automobiles.
Wireless charging, wireless charging mobile phones support up to 50W wireless charging mobile phones, a small number of mobile phones also support reverse wireless charging, but the charging power is shameful, can only say that let us look forward to the future of reverse wireless charging further development. In terms of price, each brand of mobile phone is different, which is inconvenient to say.
In fact, the first domestic mainstream mobile phone to support wireless charging technology is the Gionee M7 Plus developed by the bankrupt Gionee, and it is still 14W fast charging, which is better than XiaomiAs early as 4 months earlier, it has become the "founder" of domestic wireless charging.
W wireless charging peak has appeared on some domestic mobile phones, while overseas brands of mobile phones are generally difficult to look back. Although no phone has yet been released to support higher charging power, existing wireless charging phones have reached the maximum prescribed peak.
In addition, such as photography, wireless charging, gesture recognition, 3D modeling and other functions, domestic mobile phones are led by Huawei in the front, friends follow up, so if Huawei completely gives up self-research, friends will have less reference for evolution, the direction of evolution needsTo do their own research, the supply chain of some modules needs to be matured by themselves, the speed of evolution will slow down, and the mobile phone we buy will have fewer cool features.
1, this may be because some time ago the Ministry of Industry and Information Technology issued a document: "Wireless charging (power transmission) equipment radio management Interim Provisions" this document clearly states that since January 1, 2022, mobile, portable wireless charging equipment rated transmission power is less than 50W. In other words, millet 120W wireless second charge is not supported by the Ministry of Industry and Information Technology. The Ministry of Industry and Information Technology does not support it, not because the wireless second charge itself has any security risks.
2, and just recently, the Ministry of Industry and Information Technology issued a provisional provisions, its full name is "wireless charging (power transmission) equipment radio management interim provisions (draft for comments)", the provisional provisions on the wireless charging rated transmission power requirements is less than 50W.
3, the Ministry of Industry and Information Technology stipulates that the power of wireless fast charge must be less than 50 watts, there are such requirements in the end why they are not clear,But what they know is the limit, the power of this charge is not because of radiation, because radiation is everywhere, all the time, and not all radiation will have an impact on the human body.
4, but just now, the Ministry of Industry and Information Technology suddenly came out of new news. From next year, the power of mobile wireless charging equipment will be less than 50W, which also seems to reflect the wireless fast charging technology of mobile phone products will be limited. Mobile phone wireless fast charge may be the highest will also be fixed at 50W, of course, there is certainly a reason for such restrictions.
5, First let's look at the Ministry of Industry and Information TechnologyThe provisional regulations clearly indicate that the rated transmission power requirements of wireless charging are less than 50W.
2, the Ministry of Industry and Information Technology stipulates that the power of wireless fast charge must be less than 50 watts, there are such requirements in the end why they are not very clear, but they know that the power of this charge is not because of the reason of radiation, because radiation is everywhere, all the time, and not all radiation will have an impact on the human body.
3, "Wireless charging (power transmission) equipment radio Management Interim Provisions" clearly stated in this document, from January 1, 2022From now on, the rated transmission power of mobile and portable wireless charging devices should be less than 50W. In other words, millet 120W wireless second charge is not supported by the Ministry of Industry and Information Technology. The Ministry of Industry and Information Technology does not support it, not because the wireless second charge itself has any security risks.

To be precise, split sales, standard to separate retail, this is contraryLaw, because this makes the commodity can not achieve its normal use, only with accessories to normal use, in order to be the product itself is fully functional, so these accessories are necessary, must. First of all, the back of the hand can help children develop a kind of self-control ability, which is very important for their future growth. In kindergarten, children often need to wash their own hands, dress, eat, etc., which they need to do on their own, and the back of the hand can help them better focus and master their behavior. Secondly, the back of the hand can also help children avoid accidentally putting food or other food when eatingGet objects on your face or mouth.
The role of elbow pads, the first is to provide pressure, reduce swelling; The second is to limit movement to allow the injured area to recuperate. At the same time, it is best not to interfere with the normal functioning of the hand, so if not necessary, most elbow guards are not hampered. Elbow and knee pads are protective devices to prevent the elbow and knee from being injured by falls, and are designed with soft pads or hard shells.
The curved screen of Huawei mobile phones is not as good as the flat screen, but the difference lies in the cost, practicality, technical requirements, and impact of the full screen. Recommended reason: Curved screen design in the present dispensable. Which means it just feels likeThe feeling of bending. It is difficult to make, the cost is relatively high, so if damaged, the repair cost is also higher. The rest of the viewing experience has not changed, and there is no new and convenient technology.
1, and for the future technology of space charging, at present, millet millimeter wave does not seem to be a good solution. In addition, in Huawei's patent data, Huawei was found in 201The nine-year application of the use of long-distance laser to achieve the patent of space charging, but may become one of the ways to achieve space charging in the future.
2, according to the current technology of air separation charging, the application scenario is only mobile phones. With space charging is different, as long as the effective range of space charging, the mobile phone can be charged, especially convenient. However, the spread of air charging technology takes time, and it is necessary to break through some technical difficulties. The road of air charging technology is bound to have a long way to go. The emergence of this technology, let us take another step towards the era of superintelligence.
3, milletIn 2021, the first air-separated charging technology was announced, because it is difficult to implement algorithms and trajectory tracking using 3D large-scale arrays, so I think just looking at this project should give Xiaomi a thumbs up. However, many people now speculate that excessive electromagnetic radiation will be one of the main obstacles to the realization of mass production and practical use of this technology, however, the long road is long, millet developed this technology, certainly its use will not be less.
4, the technical principle of space charging is released from the energy source, there is a fixed frequency of radio waves and mobile phone receiving frequency match, so as to transmit power and charge. Due septumThe power loss efficiency of this technology is about 70%, but the stable power of 5 to 10w is already the limit.
5, space charging technology is actually a wireless charging technology. Wireless charging technology is a technology that uses non-physical contact to achieve power transmission. At present, there are three common wireless power transmission technologies, respectively: electromagnetic induction: the working principle is: install the transmitter coil on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging seat to charge, the transmitter coil will generate alternating magnetic field due to access to alternating current.
6, millet ldquo air separation charging technology is actually based on millet self-developed air separation charging pile to achieve, its built-in 5 phase interference antennas, can be millisecond spatial positioning of the phone, accurate detection of the location of the phone, the phase control array composed of 144 antennas, through beamforming the millimeter wave directional transmission to the phone, and hand.
