XIAOMI today is the first time to debut the research of the space charging technology, and announced the poster. The technology, pioneered by the Mi 11, does not require a dock and can charge wirelessly over long distances, either in your hand or pocket. Ahead of Xiaomi’s announcement, Motorola today unveiled its own wireless charging technology with a demo video.

As you can see in the video, unlike Motorola’s technology, Xiaomi’s barrier charging technology is not affected by foreign body shielding. Officials say there is no need to keep the phone in a fixed position, and that it can be charged wirelessly over long distances by playing it in your hand or holding it in your trouser pocket.
Lei Jun today on his personal public account in detail to introduce the separation charging technology, and at the same time showed the separation charging pile. At present, Xiaomi’s spacial charging technology has realized the long-distance charging of 5 watts for a single device within a radius of several meters. Not only that, but multiple devices can be charged at the same time (each device supports 5 watts), and even foreign body blocking does not reduce charging efficiency.

He said the technology has 17 patents, and the core technologies are space positioning and energy transmission. The self-developed spacer charging pile has 5 built-in phase interference antennas, which can carry out millisecond spatial positioning of the mobile phone and accurately detect the position of the mobile phone. A phase-controlled array of 144 antennas directs millimeter waves to the mobile phone through beamforming.

On the mobile side, Xiaomi has developed its own antenna array. Among them, the “beacon antenna” broadcasts position information in the space field through low power consumption, and the “receiving antenna array” composed of 14 antennas converts millimeter-wave signals emitted by charging piles into electric energy through the rectifying circuit, thus realizing the science-fiction spacer charging experience.

Lei also said that Xiaomi has developed its own space-based charging technology to charge wearable devices such as smart watches and wristbands. The future living room, speakers, lamps and other small smart home products, it can achieve wireless power supply, completely get rid of wire bondage, truly realize the wireless living room.

Here is the official introduction of Xiaomi’s spacial charging technology.
