A few weeks ago, the Chinese giant Huawei had filed for a patent for a new technology that relates to a wireless charging system. What is striking about this patent is that the wireless charger will be capable of ranged transmission.
The patent bears the number CN112564295A. A few reports have claimed based on the filed patent that the new wireless technology requires two coils to be placed directly opposite to each other with the distance between the two being very close to transmit power. With the new patent, the company is hoping that it can successfully increase the charging distance. This will be specifically helpful to personal wear devices.
A few reports had claimed that the wireless charging technology developed by Huawei is top-of-the-order. Moreover, the company’s own Mate40 series also supports 50W wireless charging. Incidentally, that is also used with Huawei’s super-fast charging vertical charger that comes with a maximum capacity of 50W.
Recently, developing on the previous patent, the company on April 20th published an invention patent that was called “A Transmitter, Receiver, and System for Long-distance Wireless Charging”. This one bears the number CN112689938A, and it has been confirmed that it was filed in April 2020.
The new information that surfaced regarding the patent shows that the device under scrutiny is a long-distance wireless charging transmitter. The most interesting part of the patent is that the transmitter could also be used to wireless charge the receiver. Moreover, this has also come to notice that the transmitter includes a transmitter processor, a baseband radio frequency conversion unit, and a transmitter antenna.
A few reports have claimed that the transmitting end of the device is made for wireless charging while the receiving end holds control functions through a composite signal transmission path. Furthermore, the transmitter simplifies the internal hardware structure and reduces the cost of the entire transmitter.
