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(wu)線充電(dian)(dian)器的(de)原理中(zhong)學大(da)家都學過，即安培定律和法(fa)拉第定律。安培定律是(shi)指振(zhen)蕩(dang)電(dian)(dian)場(chang)產(chan)生(sheng)振(zhen)蕩(dang)磁(ci)(ci)場(chang)，法(fa)拉第定律是(shi)指振(zhen)蕩(dang)磁(ci)(ci)場(chang)產(chan)生(sheng)振(zhen)蕩(dang)電(dian)(dian)場(chang)，無(wu)線充電(dian)(dian)即電(dian)(dian)力發(fa)射器產(chan)生(sheng)的(de)時變磁(ci)(ci)場(chang)在(zai)適當定位的(de)電(dian)(dian)力接收(shou)器中(zhong)產(chan)生(sheng)電(dian)(dian)動勢。

使用(yong)車載無(wu)線充(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(she)器(qi)(qi)通(tong)過(guo)其線圈(quan)產生交變(bian)電(dian)(dian)(dian)(dian)流，根據(ju)法拉第定(ding)律，交變(bian)電(dian)(dian)(dian)(dian)流會產生交變(bian)磁場，該(gai)(gai)磁場又由電(dian)(dian)(dian)(dian)力(li)接(jie)(jie)收器(qi)(qi)內的線圈(quan)拾(shi)取并由功率轉換(huan)器(qi)(qi)，轉換(huan)回(hui)可用(yong)于(yu)對(dui)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的直流電(dian)(dian)(dian)(dian)流。該(gai)(gai)磁場有一個特點(dian)，那就(jiu)是可以穿過(guo)塑料(liao)、玻璃、水、空氣(qi)等任(ren)何非(fei)金屬非(fei)鐵質材料(liao)，因此電(dian)(dian)(dian)(dian)力(li)發射(she)器(qi)(qi)和電(dian)(dian)(dian)(dian)力(li)接(jie)(jie)收器(qi)(qi)之間不需要電(dian)(dian)(dian)(dian)線和連接(jie)(jie)器(qi)(qi)即(ji)可實現充(chong)電(dian)(dian)(dian)(dian)功能，這(zhe)就(jiu)是無(wu)線車充(chong)的原理(li)。

二、無線車充的方式有哪些

市面上主流的車載無線充電器的方式(shi)有兩種：

1、前裝車載無線充電器

前裝(zhuang)是指(zhi)汽車在出廠前帶有無線充(chong)電(dian)裝(zhuang)置的方式，一般安裝(zhuang)在中(zhong)央(yang)儲物(wu)盒、扶手箱(xiang)位置，將手機放到充(chong)電(dian)裝(zhuang)置上(shang)即可充(chong)電(dian)。

汽(qi)車(che)前裝(zhuang)無(wu)線充(chong)(chong)電(dian)(dian)技(ji)術，來自無(wu)線充(chong)(chong)電(dian)(dian)方案商向汽(qi)車(che)主機廠提(ti)供的無(wu)線充(chong)(chong)電(dian)(dian)解決(jue)方案。一個(ge)合格的車(che)載前裝(zhuang)無(wu)線充(chong)(chong)電(dian)(dian)要求具備基(ji)礎的無(wu)線充(chong)(chong)認證、滿足嚴苛的車(che)規級(ji)(ji)硬件標準，對工作溫度范(fan)圍、防水(shui)防塵等也有(you)一定的等級(ji)(ji)要求。因此期安裝(zhuang)無(wu)線充(chong)(chong)電(dian)(dian)的廠家(jia)并不(bu)太多(duo)。

2、后裝無線車載充電器

后裝(zhuang)(zhuang)無線(xian)車(che)(che)充(chong)是指原(yuan)車(che)(che)無無線(xian)充(chong)電(dian)器(qi)裝(zhuang)(zhuang)置(zhi)(zhi)，在(zai)汽車(che)(che)上額外(wai)加裝(zhuang)(zhuang)一個車(che)(che)載支架等裝(zhuang)(zhuang)置(zhi)(zhi)來實現(xian)無線(xian)充(chong)電(dian)，通常后裝(zhuang)(zhuang)的無線(xian)車(che)(che)充(chong)安裝(zhuang)(zhuang)位(wei)置(zhi)(zhi)不固定，可安裝(zhuang)(zhuang)在(zai)空調通風口、汽車(che)(che)中控臺(tai)等位(wei)置(zhi)(zhi)，或者借助吸盤吸附(fu)在(zai)擋風玻璃上。

車載后裝無線充電(dian)，由(you)于并不屬于整車的一(yi)部分(fen)，不受(shou)很多(duo)車廠(chang)強制性認證標準的約(yue)束，因(yin)此雖然(ran)產(chan)品可靠(kao)性不及前裝，但勝在行業準入門檻低(di)、產(chan)品性價比高。
