According to the latest news, Huawei has filed a patent for new wireless charging technology. This new “wireless charging system” is capable of ranged transmission which means it can raise the distance for the wireless charging technology.
ITHome reported that the patent comes with a publication number CN112564295A. The patent describes a wireless charging technology that is capable of transmitting while having a distance between the transmitting electrode and the receiving electrode.
In simple words, it is a ranged form of wireless charging technology. The patent description states that the current wireless charging technology requires two coils to be placed directly opposite each other. The distance between the two should be very close in order to transmit power. Huawei has put forward that this greatly limits the application of wireless charging technology.
The Huawei patent states that it could work with a variety of materials like iron, aluminum, copper, other alloys, metal pipes, etc. Interestingly, the patent also details that the technology can use humans, animals, soil, earth, seawater, and other non-metallic dielectric objects to pass a charge through them as long as its conductivity is greater than that of air.
It seems this Huawei patent is seeking to raise the applications of wireless charging technology as a whole by increasing the effective range of charging. Later on, this technology could be integrated into other products like smartphones, smartwatches, and smart bands.
