小米(01810.HK)雷軍:小米11率先推出自研隔空充電技術
小米(01810.HK)董事長雷軍表示,正式發佈隔空充電技術,日前推出的旗艦產品小米11將率先推出該功能,目前隔空充電技術已實現數米半徑內單設備5瓦遠距離充電,並支援多設備充電。
雷軍指,該技術核心在於空間定位和隔空能量傳輸,自研的隔空充電樁內置5個相位干涉天線,可以對手機進行毫秒級空間定位,透過144個天線構成的相位控制陣列,通過波束成形將毫米波定向發射給手機,手機中14根天線組成的接收天線陣列,將充電樁發射的毫米波信號,通過整流電路轉化為電能,從而實現隔空充電。
他表示,不久將來小米自研隔空充電技術將可為智能手錶、手環等穿戴設備隔空充電,未來小型智能家居產品亦可以作無線供電,徹底擺脫電線束縛,實現客廳無線化。
