Xiaomi has announced that the “Me Air Charge Technol, G,” the wireless charging system the company claims is capable of charging devices within a radius of several meters. According to Xiaomi, multiple devices can be charged at 5W at the same time, and physical constraints obviously do not reduce the charging capacity.
Xiaomi says the technology will also work with smartwatches and fitness bracelets. The second goal is to make “living rooms truly truly wireless”, with speakers, lamps and smart home devices all powered by the same remote system. A representative of Xiaomi confirms this EdgeHowever, none of the commercial products include technology this year, and declined to give a timeline for release.
In Xiaomi’s words, here’s how MI air charge technology works:
The main technology of Xiaomi’s remote charging lies in space conditions and energy transfer. Xiaomi’s self-developed isolated charging pile has a built-in five-stage interference antenna, which can accurately detect the location of a smartphone. A single phase control array composed of 144 antennas by beamforming transmits millimeter-wide waves directly into the phone.
On the smartphone side, Xiaomi has also developed miniature antenna arrays with built-in “beacon antennas” and “racing antenna arrays”. Beacon antennas transmit status information with low power consumption. The receiving antenna array, made up of 14 antennas, converts the millimeter wave signal emitted by the charging pile into electric energy rays through a rectifier circuit, so that the scientific charging experience can be turned into reality.
Needless to say, unless the evidence suggests you should be able to market it about the possibility of this technology. Companies like Energies have been making announcements about “true wireless charging” at CES and beyond for many years, but this technology has not yet taken a serious step. Xiaomi has demonstrated wireless charging engineering advances in the past, though, and has the advantage of owning a huge hardware ecosystem that it could theoretically benefit from.
