無線充電器定義：

無線(xian)充電(dian)器(qi)是指利用電(dian)磁(ci)波感應原理進行(xing)充電(dian)的設備，原理類似于(yu)變壓器(qi)。在發送(song)和接收端(duan)各(ge)有一個線(xian)圈(quan)，發送(song)端(duan)線(xian)圈(quan)連接有線(xian)電(dian)源產(chan)生(sheng)電(dian)磁(ci)信(xin)號(hao)，接收端(duan)線(xian)圈(quan)感應發送(song)端(duan)的電(dian)磁(ci)信(xin)號(hao)從而產(chan)生(sheng)電(dian)流給電(dian)池充電(dian)。

　　物(wu)理學家早就知道，在兩(liang)個(ge)共振頻率(lv)相(xiang)(xiang)同(tong)的物(wu)體(ti)之間(jian)能有(you)效地(di)傳輸(shu)能量(liang)，而不(bu)同(tong)頻率(lv)物(wu)體(ti)之間(jian)的相(xiang)(xiang)互作用(yong)較(jiao)弱。歌唱家演唱能將裝有(you)不(bu)同(tong)水量(liang)瓶子中的一(yi)個(ge)震碎(sui)，而不(bu)影響其他瓶子就是這(zhe)個(ge)道理。這(zhe)也好比(bi)我們蕩秋千(qian)時，只需坐在上面讓下垂的雙腿同(tong)步擺(bai)動(dong)(dong)就能給(gei)秋千(qian)帶(dai)來動(dong)(dong)力一(yi)樣。

無(wu)(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)技(ji)(ji)術正是(shi)利用了這(zhe)個(ge)原理(li)(li)。同(tong)樣，無(wu)(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)技(ji)(ji)術也應用了電(dian)(dian)磁波感(gan)應原理(li)(li)，及相關的(de)(de)交(jiao)流感(gan)應技(ji)(ji)術，在(zai)(zai)發送和(he)接(jie)收端(duan)用相應的(de)(de)線(xian)(xian)圈來發送和(he)接(jie)收產生感(gan)應的(de)(de)交(jiao)流信(xin)號(hao)來進(jin)行充(chong)(chong)(chong)電(dian)(dian)的(de)(de)的(de)(de)一(yi)(yi)項(xiang)技(ji)(ji)術， 用戶只需要將(jiang)充(chong)(chong)(chong)電(dian)(dian)設備放(fang)在(zai)(zai)一(yi)(yi)個(ge)“平板”上(shang)即可(ke)進(jin)行充(chong)(chong)(chong)電(dian)(dian)，這(zhe)樣的(de)(de)充(chong)(chong)(chong)電(dian)(dian)方(fang)式過去(qu)曾經出現在(zai)(zai)手(shou)表和(he)剃(ti)須刀上(shang)，但是(shi)當時(shi)無(wu)(wu)法針對大容量鋰(li)離子電(dian)(dian)池(chi)進(jin)行有效充(chong)(chong)(chong)電(dian)(dian)。無(wu)(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)器(qi)技(ji)(ji)術原理(li)(li)構圖如圖所示

無(wu)線充(chong)電(dian)技術此前已經出現(xian)，但(dan)這項(xiang)新(xin)發明更(geng)為方便實用。手機等(deng)(deng)設備只要(yao)貼上接收線圈，放(fang)置在(zai)(zai)“鼠標墊”上的任一(yi)位(wei)置都可充(chong)電(dian)，不(bu)像以前的一(yi)些(xie)技術那樣需要(yao)精確定位(wei)。幾個設備同時放(fang)在(zai)(zai)墊子上，可以同時進行充(chong)電(dian)。充(chong)電(dian)器產生(sheng)的磁(ci)場很弱，能(neng)夠給設備充(chong)電(dian)但(dan)不(bu)會影(ying)響附近的信(xin)用卡、錄像帶等(deng)(deng)利用磁(ci)性記錄數據的物品(pin)。
