無線充(chong)電器是指(zhi)不用(yong)傳統(tong)的(de)(de)(de)充(chong)電(dian)電(dian)源線(xian)(xian)連接到需要充(chong)電(dian)的(de)(de)(de)終端設備上(shang)的(de)(de)(de)充(chong)電(dian)器，采用(yong)了最新的(de)(de)(de)無線(xian)(xian)充(chong)電(dian)技術，通過使用(yong)線(xian)(xian)圈之間產生(sheng)的(de)(de)(de)交變磁場(chang)，傳輸電(dian)能，電(dian)感耦合技術將會成為連接充(chong)電(dian)基站和設備的(de)(de)(de)橋梁(liang)。

特點(dian)

1.從理論來說，無(wu)(wu)線(xian)充(chong)電(dian)技(ji)(ji)術(shu)對人體安(an)全無(wu)(wu)害處(chu)，無(wu)(wu)線(xian)充(chong)電(dian)使(shi)用(yong)(yong)的共(gong)振(zhen)(zhen)原理是(shi)(shi)磁(ci)場(chang)共(gong)振(zhen)(zhen)，只在以同(tong)一頻(pin)率共(gong)振(zhen)(zhen)的線(xian)圈之間(jian)傳輸，而其(qi)他裝置無(wu)(wu)法接受波(bo)段，另外，無(wu)(wu)線(xian)充(chong)電(dian)技(ji)(ji)術(shu)使(shi)用(yong)(yong)的磁(ci)場(chang)本(ben)身就是(shi)(shi)對人體無(wu)(wu)害的。但無(wu)(wu)線(xian)充(chong)電(dian)技(ji)(ji)術(shu)畢竟是(shi)(shi)新型的充(chong)電(dian)技(ji)(ji)術(shu)，很多人都會擔憂無(wu)(wu)線(xian)充(chong)電(dian)技(ji)(ji)術(shu)會像當(dang)初Wi-Fi和(he)手(shou)機天(tian)線(xian)桿剛出現一樣，其(qi)實(shi)技(ji)(ji)術(shu)本(ben)身是(shi)(shi)無(wu)(wu)害的。
2.無線(xian)充(chong)電(dian)(dian)技術利(li)用磁共振(zhen)在充(chong)電(dian)(dian)器與設(she)備之(zhi)間的電(dian)(dian)場和磁場中傳輸電(dian)(dian)能，線(xian)圈和電(dian)(dian)容(rong)器則在充(chong)電(dian)(dian)器與設(she)備之(zhi)間形(xing)成共振(zhen)。
3.這一系統可以(yi)在未來得到廣泛應(ying)用，例如針對電動汽車的(de)充(chong)電區以(yi)及針對電腦(nao)芯片的(de)電量(liang)傳輸。采用這項技術(shu)研(yan)制(zhi)的(de)充(chong)電系統所需要(yao)的(de)充(chong)電時間只有當前的(de)一百五十分之(zhi)一。
4.轉化率一直是很多人擔心的問題(ti)，麻省理工學院通(tong)過(guo)研(yan)究表(biao)明，無線(xian)(xian)(xian)充(chong)電(dian)技(ji)術(shu)(shu)的損耗(hao)比起有線(xian)(xian)(xian)充(chong)電(dian)技(ji)術(shu)(shu)來(lai)說更低(di)。無線(xian)(xian)(xian)充(chong)電(dian)轉化率比起有線(xian)(xian)(xian)要高(gao)幾個(ge)百分點。高(gao)轉化，也是無線(xian)(xian)(xian)充(chong)電(dian)器得以在全球進行應用的關鍵因素(su)。但無線(xian)(xian)(xian)充(chong)電(dian)技(ji)術(shu)(shu)也受到距(ju)離的限制，未來(lai)發展，必然需要解決遠距(ju)離傳送(song)對于波(bo)段和磁(ci)場范圍(wei)的精準(zhun)定位(wei)問題(ti)。
5.核(he)心芯片(pian)是(shi)無線充電技術在(zai)產品應用的難點之一。精準輻(fu)射范圍控制(zhi)，磁場(chang)頻率大小，其它(ta)控制(zhi)等都是(shi)由(you)芯片(pian)實(shi)現。
