雷军：小米正式发布隔空充电技术，率先在小米11上实现

1月29日，雷军在个人公众号发文宣布，小米正式发布隔空充电技术，并率先在小米11上实现。

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.

雷军表示，从2018年开始，小米已经连续多次打破手机行业的无线充电纪录。2020年8月，小米全球首发了80瓦无线秒充技术，充电效率几乎媲美市面上最快的有线快充。

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.

据了解，小米隔空充电，技术核心在于空间定位和隔空能量传输。自研的隔空充电桩内置5个相位干涉天线，可以对手机进行毫秒级空间定位，精准探测手机位置。144个天线构成的相位控制阵列，通过波束成形将毫米波定向发射给手机。

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.

目前小米隔空充电技术，已经实现了数米半径内，单设备5瓦远距离充电。不仅于此，多设备也可以同时充电(每台设备均支持5瓦)，甚至异物遮挡也不降低充电效率。

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.
