無線(xian)充電器(qi)是指不用(yong)(yong)傳統的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)線(xian)連接到需要充(chong)電(dian)(dian)(dian)的(de)終端設(she)備(bei)(bei)上的(de)充(chong)電(dian)(dian)(dian)器(qi)，采(cai)用(yong)(yong)了(le)最新的(de)無線(xian)充(chong)電(dian)(dian)(dian)技術(shu)，通過使用(yong)(yong)線(xian)圈之間產(chan)生的(de)交變(bian)磁場，傳輸電(dian)(dian)(dian)能，電(dian)(dian)(dian)感耦合技術(shu)將會成為連接充(chong)電(dian)(dian)(dian)基站和設(she)備(bei)(bei)的(de)橋梁。

特點

1.從理(li)論來說，無(wu)(wu)(wu)線(xian)(xian)充電技(ji)(ji)術(shu)(shu)(shu)(shu)對人(ren)體安(an)全(quan)無(wu)(wu)(wu)害(hai)處，無(wu)(wu)(wu)線(xian)(xian)充電使用的(de)(de)(de)(de)共振原理(li)是(shi)磁場共振，只在以同一頻率共振的(de)(de)(de)(de)線(xian)(xian)圈之間傳輸，而其(qi)他裝置無(wu)(wu)(wu)法接受波段，另外，無(wu)(wu)(wu)線(xian)(xian)充電技(ji)(ji)術(shu)(shu)(shu)(shu)使用的(de)(de)(de)(de)磁場本身就是(shi)對人(ren)體無(wu)(wu)(wu)害(hai)的(de)(de)(de)(de)。但無(wu)(wu)(wu)線(xian)(xian)充電技(ji)(ji)術(shu)(shu)(shu)(shu)畢竟(jing)是(shi)新型的(de)(de)(de)(de)充電技(ji)(ji)術(shu)(shu)(shu)(shu)，很多(duo)人(ren)都會(hui)擔(dan)憂無(wu)(wu)(wu)線(xian)(xian)充電技(ji)(ji)術(shu)(shu)(shu)(shu)會(hui)像當(dang)初Wi-Fi和手機(ji)天線(xian)(xian)桿剛出現一樣，其(qi)實技(ji)(ji)術(shu)(shu)(shu)(shu)本身是(shi)無(wu)(wu)(wu)害(hai)的(de)(de)(de)(de)。
2.無線充電(dian)(dian)技術利用磁共(gong)(gong)振(zhen)在充電(dian)(dian)器與設(she)備之間的(de)電(dian)(dian)場和(he)磁場中傳輸電(dian)(dian)能，線圈和(he)電(dian)(dian)容(rong)器則在充電(dian)(dian)器與設(she)備之間形成共(gong)(gong)振(zhen)。
3.這一(yi)系統(tong)可以(yi)在未(wei)來得(de)到廣泛應用，例如針對(dui)電(dian)(dian)(dian)動汽車的(de)充電(dian)(dian)(dian)區以(yi)及針對(dui)電(dian)(dian)(dian)腦(nao)芯片的(de)電(dian)(dian)(dian)量(liang)傳輸。采(cai)用這項技術(shu)研制(zhi)的(de)充電(dian)(dian)(dian)系統(tong)所需要的(de)充電(dian)(dian)(dian)時間(jian)只有當前(qian)的(de)一(yi)百(bai)五十(shi)分之一(yi)。
4.轉(zhuan)化(hua)率一直是很(hen)多人擔心(xin)的問題，麻省理(li)工學院通(tong)過研究表明，無線(xian)充(chong)電技術(shu)的損(sun)耗比起(qi)有(you)線(xian)充(chong)電技術(shu)來說更(geng)低。無線(xian)充(chong)電轉(zhuan)化(hua)率比起(qi)有(you)線(xian)要(yao)(yao)高(gao)幾個百(bai)分(fen)點。高(gao)轉(zhuan)化(hua)，也(ye)是無線(xian)充(chong)電器得(de)以在(zai)全球進行應用(yong)的關鍵因素。但無線(xian)充(chong)電技術(shu)也(ye)受到距(ju)(ju)離(li)的限制，未來發展，必然需要(yao)(yao)解(jie)決遠距(ju)(ju)離(li)傳送對于波段和磁場(chang)范(fan)圍的精準定位問題。
5.核心芯片是無(wu)線(xian)充電技術在產品應用(yong)的難點之一。精準輻射范圍(wei)控制，磁(ci)場頻率大小(xiao)，其(qi)它控制等都是由(you)芯片實現。
