The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
Currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. Existing wireless charging technology worksMagnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains in the laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.
New breakthrough in wireless charging technology: Wi-Fi charging is realized in the near future The development of wireless charging technology has made remarkable progress, and wireless charging of mobile phones has become the norm in daily life. And now, the Japanese media has brought more exciting news: a remote charging technology based on radio waves is gradually becoming practical in Japan.Similar to Wi-Fi, it can power devices such as robots, electronic price tags and smartphones from up to 10 meters away.
is next to the transmitter), at the same time, they are also working on long-distance wireless charging, which will be an emerging market. In fact, the current technology can achieve effective power transmission in the range of 3 to 4 feet, but this needs to be verified by the relevant organization. I believe that in the next 5 to 10 years, or even sooner, long-distance wireless charging will enter everyone's life.
The transmission distance of high-power wireless charging is generally about 0.9-2 metersIf you put a plastic sheet between the phone and the charger, it can be charged, as long as your plastic sheet is not too thick, if too thick. It can't be charged. Wireless charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. The best charging distance is 2-4mm, the coil can not be directly close.
In the wireless charging of new energy vehicles, the greater the coil interval, the higher the efficiency of charging. The efficiency of wireless charging is related to power, the greater the power, the greater the magnetic field range, the closer the distance, the better the efficiency, and the receiving coil and the transmittingThe closer the coils are, the more efficient the energy conversion is. The smaller the coil spacing, the higher the efficiency.
Wireless charging transmission, receiving module component specifications, the distance between the coil, the interval material material will have an impact on the charging efficiency, there are a lot of wireless charger program related information available for query, your wireless charging program for what purpose, different technical solutions charging efficiency is very different.
Of course, it should be noted that there can be no other things between the phone and the charger.
See very little now. The wireless charging of these mobile phones is all QITechnology, the charging interval is relatively small, about 5mm, the placement is also required to be accurate, slightly wrong a few millimeters, may not be able to charge. If you are interested, you can pay attention to the technology of A4WP, which is also the main technology promoted by Intel and Qualcomm. Domestic micro goose technology and BYD are also doing technical research in this direction.
is currently under research and is not yet on the market. Radio wave charging is different from the above two charging methods. By configuring a radio wave transmitting device in the power supply and a radio wave receiving device in the power receiver, DC voltage output and input are usedTransmit power. Its advantage is that the transmission interval is medium, the transmission speed is fast, the disadvantage is that the stability and security are low, and it requires a certain cost to invest in research and development.
1, not generally in 0.9-2 meters or so high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways.
2, mobile phone charging space technology appeared millet launched this new technology, through their unique chargingThe device and the mobile phone can achieve air charging, the distance of the air can be one meter, it can be two meters, within a certain range are useful, but the charging speed is not so high, if it is this air charging, it is now 5 watts of charging power.
3, the core magnetic resonance long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
4, we often say that wireless charging actually has great limitations, the effective distance is generally only 8 mm -15 mm, in this range can be normal wireless charging, the so-called space is separatedIt's just an empty phone case. If there is a metal interval, it will affect the normal charging.
5, another kind of air separation charging device is a wireless charging emission scheme that meets the requirements of ROHS, using low-frequency magnetic resonance wireless charging technology, making the charging distance greatly increased, the furthest charging distance can reach 35mm, easily realize the convenience brought by wireless. The application of this solution can realize the wireless charging transmitter products placed on the desktop (non-metal or magnetic conductive material) below, mobile phones, laptops and other Qi standard equipment placed on the desktop, can be wireless charging/power supply.
6, radio wave type: the working principle 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. But Xiaomi's technology is different from all three.
