無線充電器是指不(bu)用(yong)傳(chuan)統的(de)(de)充(chong)電(dian)電(dian)源線(xian)連接到需要充(chong)電(dian)的(de)(de)終端設備上的(de)(de)充(chong)電(dian)器，采用(yong)了最(zui)新的(de)(de)無線(xian)充(chong)電(dian)技術，通過使用(yong)線(xian)圈之間產生的(de)(de)交變磁場，傳(chuan)輸電(dian)能，電(dian)感耦合技術將會成為連接充(chong)電(dian)基(ji)站和設備的(de)(de)橋梁(liang)。

特點

1.從理(li)論來說，無(wu)(wu)線充(chong)(chong)電(dian)(dian)技術對人(ren)體安全無(wu)(wu)害處(chu)，無(wu)(wu)線充(chong)(chong)電(dian)(dian)使用的(de)共(gong)振(zhen)原理(li)是磁場(chang)共(gong)振(zhen)，只在(zai)以同一頻率共(gong)振(zhen)的(de)線圈之間(jian)傳(chuan)輸，而其(qi)他裝置無(wu)(wu)法(fa)接受波段(duan)，另外，無(wu)(wu)線充(chong)(chong)電(dian)(dian)技術使用的(de)磁場(chang)本身就(jiu)是對人(ren)體無(wu)(wu)害的(de)。但無(wu)(wu)線充(chong)(chong)電(dian)(dian)技術畢竟是新(xin)型(xing)的(de)充(chong)(chong)電(dian)(dian)技術，很多人(ren)都會擔憂無(wu)(wu)線充(chong)(chong)電(dian)(dian)技術會像當初(chu)Wi-Fi和手機天(tian)線桿剛出現一樣(yang)，其(qi)實技術本身是無(wu)(wu)害的(de)。
2.無線充電(dian)(dian)(dian)(dian)技術利用磁(ci)共振在充電(dian)(dian)(dian)(dian)器與(yu)設(she)備(bei)之間的電(dian)(dian)(dian)(dian)場(chang)和磁(ci)場(chang)中傳(chuan)輸電(dian)(dian)(dian)(dian)能，線圈(quan)和電(dian)(dian)(dian)(dian)容器則在充電(dian)(dian)(dian)(dian)器與(yu)設(she)備(bei)之間形成共振。
3.這(zhe)一(yi)系統可以在(zai)未(wei)來(lai)得到廣泛應用，例如(ru)針對(dui)電(dian)動汽車的充(chong)電(dian)區以及針對(dui)電(dian)腦芯片的電(dian)量(liang)傳輸。采用這(zhe)項技術研制的充(chong)電(dian)系統所需(xu)要的充(chong)電(dian)時間只有當前(qian)的一(yi)百五十分之一(yi)。
4.轉化率一直(zhi)是很多人擔(dan)心(xin)的問(wen)題，麻省理工學(xue)院通過研(yan)究(jiu)表明，無線充(chong)電(dian)(dian)(dian)技術(shu)的損耗比(bi)起有線充(chong)電(dian)(dian)(dian)技術(shu)來說更(geng)低。無線充(chong)電(dian)(dian)(dian)轉化率比(bi)起有線要高幾個百分點。高轉化，也(ye)是無線充(chong)電(dian)(dian)(dian)器得以在全球進(jin)行(xing)應用的關鍵因素(su)。但(dan)無線充(chong)電(dian)(dian)(dian)技術(shu)也(ye)受到距離的限制，未來發展，必(bi)然(ran)需要解(jie)決遠距離傳送對于波段和(he)磁場范圍的精準(zhun)定(ding)位問(wen)題。
5.核(he)心芯片是(shi)無線充(chong)電技(ji)術(shu)在產(chan)品應(ying)用的難點之一。精(jing)準輻射(she)范圍控制，磁(ci)場頻率大小(xiao)，其它(ta)控制等都是(shi)由芯片實(shi)現。
