一、車載無線充電器原理是什么

車載無線充電器不需要數據線，充電時只需要將手機放在充電座上即可，隨用隨取，十分方便，那么無線車載充電器什么原理呢？

車載無線充電(dian)(dian)器的原理中(zhong)學大家都(dou)學過，即安培定(ding)律(lv)和(he)法(fa)(fa)拉第定(ding)律(lv)。安培定(ding)律(lv)是(shi)(shi)指振(zhen)(zhen)蕩電(dian)(dian)場(chang)(chang)(chang)產(chan)生振(zhen)(zhen)蕩磁(ci)場(chang)(chang)(chang)，法(fa)(fa)拉第定(ding)律(lv)是(shi)(shi)指振(zhen)(zhen)蕩磁(ci)場(chang)(chang)(chang)產(chan)生振(zhen)(zhen)蕩電(dian)(dian)場(chang)(chang)(chang)，無線充電(dian)(dian)即電(dian)(dian)力(li)發射器產(chan)生的時變磁(ci)場(chang)(chang)(chang)在適當(dang)定(ding)位的電(dian)(dian)力(li)接收器中(zhong)產(chan)生電(dian)(dian)動勢。

使用車(che)載無線(xian)(xian)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)充(chong)電(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)力(li)發射器(qi)(qi)通過(guo)(guo)其(qi)線(xian)(xian)圈(quan)產(chan)生(sheng)交變(bian)(bian)電(dian)(dian)(dian)(dian)流(liu)(liu)，根據(ju)法拉第定律(lv)，交變(bian)(bian)電(dian)(dian)(dian)(dian)流(liu)(liu)會產(chan)生(sheng)交變(bian)(bian)磁(ci)場(chang)(chang)，該(gai)磁(ci)場(chang)(chang)又(you)由電(dian)(dian)(dian)(dian)力(li)接收(shou)器(qi)(qi)內的(de)線(xian)(xian)圈(quan)拾(shi)取并由功(gong)率(lv)轉換器(qi)(qi)，轉換回可(ke)用于對(dui)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)。該(gai)磁(ci)場(chang)(chang)有(you)一個(ge)特點，那就是可(ke)以穿(chuan)過(guo)(guo)塑料、玻璃、水(shui)、空(kong)氣(qi)等任何非(fei)金屬非(fei)鐵質材料，因此電(dian)(dian)(dian)(dian)力(li)發射器(qi)(qi)和電(dian)(dian)(dian)(dian)力(li)接收(shou)器(qi)(qi)之間不需要電(dian)(dian)(dian)(dian)線(xian)(xian)和連(lian)接器(qi)(qi)即可(ke)實現充(chong)電(dian)(dian)(dian)(dian)功(gong)能，這(zhe)就是無線(xian)(xian)車(che)充(chong)的(de)原理。

二、無線車充的方式有哪些

市(shi)面上主流的車(che)載無(wu)線(xian)充電器的方式有兩種：

1、前裝車載無線充電器

前裝是指汽(qi)車在(zai)出廠(chang)前帶有無線充(chong)(chong)電(dian)裝置的方式，一般安(an)裝在(zai)中央(yang)儲(chu)物盒、扶(fu)手(shou)(shou)箱位置，將(jiang)手(shou)(shou)機放到充(chong)(chong)電(dian)裝置上即可充(chong)(chong)電(dian)。

汽車前裝(zhuang)無線(xian)(xian)充(chong)電技術，來自無線(xian)(xian)充(chong)電方(fang)(fang)案商向汽車主機廠(chang)提供的(de)無線(xian)(xian)充(chong)電解決方(fang)(fang)案。一個合格的(de)車載(zai)前裝(zhuang)無線(xian)(xian)充(chong)電要求(qiu)具備基(ji)礎的(de)無線(xian)(xian)充(chong)認(ren)證、滿足嚴苛的(de)車規(gui)級硬件(jian)標準，對(dui)工作溫度(du)范圍、防水防塵等也有一定的(de)等級要求(qiu)。因此期安裝(zhuang)無線(xian)(xian)充(chong)電的(de)廠(chang)家并不(bu)太多(duo)。

2、后裝無線車載充電器

后裝無線車充(chong)是指原車無無線充(chong)電(dian)器裝置(zhi)，在汽(qi)車上額外加(jia)裝一個車載支架等裝置(zhi)來實現無線充(chong)電(dian)，通常后裝的無線車充(chong)安(an)裝位置(zhi)不(bu)固定，可安(an)裝在空(kong)調通風口、汽(qi)車中控臺等位置(zhi)，或者借助吸盤吸附(fu)在擋風玻璃上。

車載后裝(zhuang)無線充(chong)電(dian)，由于(yu)(yu)并不(bu)屬于(yu)(yu)整(zheng)車的一部分(fen)，不(bu)受很(hen)多車廠(chang)強制性(xing)(xing)認(ren)證標準的約束，因(yin)此雖然產(chan)品可(ke)靠性(xing)(xing)不(bu)及前裝(zhuang)，但(dan)勝(sheng)在行業準入門檻(jian)低(di)、產(chan)品性(xing)(xing)價比高。
