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(xian)充(chong)電(dian)(dian)器的(de)(de)原理中學(xue)(xue)大家都學(xue)(xue)過,即(ji)安培定(ding)律(lv)和(he)法拉第定(ding)律(lv)。安培定(ding)律(lv)是指(zhi)振(zhen)蕩(dang)(dang)電(dian)(dian)場產(chan)(chan)生(sheng)振(zhen)蕩(dang)(dang)磁(ci)場,法拉第定(ding)律(lv)是指(zhi)振(zhen)蕩(dang)(dang)磁(ci)場產(chan)(chan)生(sheng)振(zhen)蕩(dang)(dang)電(dian)(dian)場,無線(xian)充(chong)電(dian)(dian)即(ji)電(dian)(dian)力(li)發射器產(chan)(chan)生(sheng)的(de)(de)時變磁(ci)場在適當(dang)定(ding)位的(de)(de)電(dian)(dian)力(li)接收器中產(chan)(chan)生(sheng)電(dian)(dian)動勢。
使(shi)用(yong)車載無線充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時,電(dian)(dian)(dian)(dian)力(li)發射(she)器(qi)(qi)(qi)(qi)通過其(qi)線圈產生(sheng)交變(bian)(bian)電(dian)(dian)(dian)(dian)流,根據法拉第定律,交變(bian)(bian)電(dian)(dian)(dian)(dian)流會產生(sheng)交變(bian)(bian)磁(ci)(ci)場,該(gai)磁(ci)(ci)場又由電(dian)(dian)(dian)(dian)力(li)接收器(qi)(qi)(qi)(qi)內的(de)線圈拾(shi)取并由功率轉換(huan)器(qi)(qi)(qi)(qi),轉換(huan)回可用(yong)于(yu)對電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)直流電(dian)(dian)(dian)(dian)流。該(gai)磁(ci)(ci)場有一個特點(dian),那就(jiu)是可以(yi)穿過塑料、玻璃、水、空氣等任何(he)非(fei)金屬非(fei)鐵質材料,因此電(dian)(dian)(dian)(dian)力(li)發射(she)器(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)力(li)接收器(qi)(qi)(qi)(qi)之間(jian)不(bu)需要電(dian)(dian)(dian)(dian)線和連接器(qi)(qi)(qi)(qi)即(ji)可實現充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)功能,這就(jiu)是無線車充(chong)(chong)(chong)的(de)原(yuan)理。
二、無線車充的方式有哪些
市(shi)面上(shang)主流的車載無線充電器的方式有兩種:
1、前裝車載無線充電器
前裝(zhuang)(zhuang)是指(zhi)汽車在(zai)(zai)出廠(chang)前帶有無(wu)線充(chong)電裝(zhuang)(zhuang)置(zhi)(zhi)的方式,一(yi)般(ban)安裝(zhuang)(zhuang)在(zai)(zai)中央儲物盒(he)、扶手箱位置(zhi)(zhi),將手機放到充(chong)電裝(zhuang)(zhuang)置(zhi)(zhi)上(shang)即可(ke)充(chong)電。
汽(qi)車(che)(che)前(qian)(qian)裝無線(xian)充電(dian)(dian)技術,來自無線(xian)充電(dian)(dian)方(fang)案(an)商向汽(qi)車(che)(che)主機廠(chang)提(ti)供的(de)無線(xian)充電(dian)(dian)解決方(fang)案(an)。一個(ge)合格的(de)車(che)(che)載(zai)前(qian)(qian)裝無線(xian)充電(dian)(dian)要(yao)(yao)求具(ju)備基礎的(de)無線(xian)充認證(zheng)、滿(man)足嚴苛的(de)車(che)(che)規(gui)級硬件標準,對工(gong)作溫度范圍、防水防塵等(deng)(deng)也有一定的(de)等(deng)(deng)級要(yao)(yao)求。因此(ci)期安裝無線(xian)充電(dian)(dian)的(de)廠(chang)家并不太多。
2、后裝無線車載充電器
后(hou)裝(zhuang)(zhuang)無線(xian)車(che)充(chong)(chong)是指原車(che)無無線(xian)充(chong)(chong)電器裝(zhuang)(zhuang)置(zhi),在汽(qi)(qi)車(che)上(shang)額外加裝(zhuang)(zhuang)一個車(che)載(zai)支(zhi)架等裝(zhuang)(zhuang)置(zhi)來實現(xian)無線(xian)充(chong)(chong)電,通常后(hou)裝(zhuang)(zhuang)的(de)無線(xian)車(che)充(chong)(chong)安裝(zhuang)(zhuang)位置(zhi)不固定,可安裝(zhuang)(zhuang)在空調通風口、汽(qi)(qi)車(che)中控臺等位置(zhi),或(huo)者借助吸盤吸附在擋風玻璃上(shang)。
車載后裝無(wu)線充(chong)電,由于并不(bu)(bu)屬(shu)于整車的一(yi)部分,不(bu)(bu)受很多車廠強制性(xing)認證(zheng)標準的約(yue)束,因此雖然產品(pin)可靠(kao)性(xing)不(bu)(bu)及前裝,但勝在行業準入(ru)門檻低、產品(pin)性(xing)價比高。
