1, currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and so on as energyThe transfer medium. 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.
2, generally about 0.9-2 meters 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. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
3, dear: It looks like youCloth's Mi 8 is very likely to support this function, and it is very close to us.

4, the distance of wireless chargers produced by different manufacturers will be different, generally speaking, effective charging can be achieved within 2 to 3 meters.
5, wireless chargingThe distance between the transmitting and receiving coils of electricity is about 8mm. The QI standard is not just the distance between the two, but the frequency and communication protocol of the two wireless charging standards. This distance is a maximum distance, beyond which the efficiency of wireless reception is very low. So it doesn't have to be 8mm.
6, however, there are some limitations to using wireless charging. The first is the limitation of distance, because the conduction distance of electromagnetic induction is limited, in general, wireless charging equipment needs to be kept at a distance of a few centimeters to tens of centimeters from the charger to charge. The second is poor performanceDifferent, because the power of different phones and chargers is different, so there may be a slower charging speed.

The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
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.
