1月29日，雷軍在個(gè)人公眾號(hào)發(fā)文宣布，小米正式發(fā)布隔空充電技術(shù)，并率先在小米11上實(shí)現(xiàn)。

On January 29th, Lei Jun announced on his personal public account that Xiaomi officially released the air charging technology and was the first to implement it on Xiaomi 11.

雷軍表示，從2018年開始，小米已經(jīng)連續(xù)多次打破手機(jī)行業(yè)的無線充電紀(jì)錄。2020年8月，小米全球首發(fā)了80瓦無線秒充技術(shù)，充電效率幾乎媲美市面上最快的有線快充。

Lei Jun said that starting in 2018, Xiaomi has repeatedly broken the wireless charging record in the mobile phone industry. In August 2020, Xiaomi launched the world's first 80-watt wireless second charging technology, the charging efficiency is almost comparable to the fastest wired fast charging on the market.

據(jù)了解，小米隔空充電，技術(shù)核心在于空間定位和隔空能量傳輸。自研的隔空充電樁內(nèi)置5個(gè)相位干涉天線，可以對(duì)手機(jī)進(jìn)行毫秒級(jí)空間定位，精準(zhǔn)探測(cè)手機(jī)位置。144個(gè)天線構(gòu)成的相位控制陣列，通過波束成形將毫米波定向發(fā)射給手機(jī)。

It is understood that the core technology of Xiaomi charging in 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.

目前小米隔空充電技術(shù)，已經(jīng)實(shí)現(xiàn)了數(shù)米半徑內(nèi)，單設(shè)備5瓦遠(yuǎn)距離充電。不僅于此，多設(shè)備也可以同時(shí)充電(每臺(tái)設(shè)備均支持5瓦)，甚至異物遮擋也不降低充電效率。

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, 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.
