小米雷军:小米11率先推出自研隔空充电技术
小米(01810.HK)董事长雷军表示,正式发布隔空充电技术,日前推出的旗舰产品小米11将率先推出该功能,目前隔空充电技术已实现数米半径内单设备5瓦远距离充电,并支援多设备充电。
雷军指,该技术核心在於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,透过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,手机中14根天线组成的接收天线阵列,将充电桩发射的毫米波信号,通过整流电路转化为电能,从而实现隔空充电。
他表示,不久将来小米自研隔空充电技术将可为智能手表、手环等穿戴设备隔空充电,未来小型智能家居产品亦可以作无线供电,彻底摆脱电线束缚,实现客厅无线化。
