Just imagine, what is the future wireless charging method? Perhaps once you enter the house, you don’t need any charging cable or charging base. Whether you hold your phone in your pocket or hold it, you can automatically charge the battery.
Today, we bring this kind of scene that only exists in science fiction movies into reality. Xiaomi officially released its self-developed wireless air charging technology, which is the first to enter the era of true wireless.
The self-developed air charging system
17 technical patents
The core technology of Xiaomi charging in the air is space positioning and energy transmission in air. The self-developed aerial charging pile has built-in 5 phase interference antennas, which can position the mobile phone in millisecond space and accurately detect the position of the mobile phone. The phase control array composed of 144 antennas transmits millimeter waves to the mobile phone through beamforming.
On the mobile phone side, Xiaomi has also self-developed the miniaturized design of the antenna array, with a built-in “beacon antenna” and “receiving antenna array”. The beacon antenna broadcasts location information in the space field through low power consumption. The receiving antenna array composed of 14 antennas converts the millimeter-wave signal emitted by the charging pile into electric energy through the rectifier circuit, realizing the science fiction air-space charging experience.
At present, Xiaomi’s air-to-air charging technology has achieved 5 watts of long-distance charging for a single device within a radius of several meters. Not only that, but multiple devices can also be charged at the same time (each device supports 5 watts), and even foreign objects will not reduce the charging efficiency.
Future living room
Willfully enter the wireless era
Shortly, Xiaomi’s self-developed space charging technology can also charge smartwatches, bracelets, and other wearable devices in space. In the future, the living room, speakers, desk lamps, and other small smart home products can realize wireless power supply, completely get rid of the shackles of wires, and truly realize the wireless nation of the living room.
This is a revolutionary innovation in wireless charging
This is also a bold attempt to make the whole house wireless
This is not science fiction, but technology
This is the wireless air charging technology developed by Xiaomi
