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)線充電器的(de)原理(li)中學(xue)大家都學(xue)過,即(ji)安(an)培(pei)定律(lv)(lv)和法拉(la)第定律(lv)(lv)。安(an)培(pei)定律(lv)(lv)是指振蕩(dang)電場(chang)(chang)產(chan)生(sheng)振蕩(dang)磁場(chang)(chang),法拉(la)第定律(lv)(lv)是指振蕩(dang)磁場(chang)(chang)產(chan)生(sheng)振蕩(dang)電場(chang)(chang),無(wu)線充電即(ji)電力(li)(li)發射(she)器產(chan)生(sheng)的(de)時變磁場(chang)(chang)在適(shi)當定位的(de)電力(li)(li)接收(shou)器中產(chan)生(sheng)電動勢。
使用車(che)載無線充電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)充電(dian)(dian)(dian)(dian)(dian)時,電(dian)(dian)(dian)(dian)(dian)力(li)(li)發射器(qi)(qi)(qi)(qi)(qi)通過(guo)其線圈(quan)產生(sheng)交變電(dian)(dian)(dian)(dian)(dian)流(liu),根據法(fa)拉第定律,交變電(dian)(dian)(dian)(dian)(dian)流(liu)會(hui)產生(sheng)交變磁場,該磁場又由電(dian)(dian)(dian)(dian)(dian)力(li)(li)接收器(qi)(qi)(qi)(qi)(qi)內的線圈(quan)拾(shi)取并由功(gong)率(lv)轉(zhuan)換(huan)器(qi)(qi)(qi)(qi)(qi),轉(zhuan)換(huan)回可(ke)用于對電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)的直流(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)。該磁場有一個特(te)點,那就是可(ke)以穿過(guo)塑料、玻璃、水、空氣(qi)等(deng)任何非金屬非鐵質材料,因此電(dian)(dian)(dian)(dian)(dian)力(li)(li)發射器(qi)(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)力(li)(li)接收器(qi)(qi)(qi)(qi)(qi)之間不需要電(dian)(dian)(dian)(dian)(dian)線和連接器(qi)(qi)(qi)(qi)(qi)即可(ke)實(shi)現充電(dian)(dian)(dian)(dian)(dian)功(gong)能,這就是無線車(che)充的原(yuan)理。
二、無線車充的方式有哪些
市面上主流的車載(zai)無線充電(dian)器(qi)的方式有兩(liang)種:
1、前裝車載無線充電器
前裝(zhuang)是指汽車在出廠前帶有無線充(chong)電(dian)裝(zhuang)置(zhi)的方(fang)式,一般安裝(zhuang)在中央儲物(wu)盒、扶手(shou)箱位置(zhi),將手(shou)機放到充(chong)電(dian)裝(zhuang)置(zhi)上即可充(chong)電(dian)。
汽車前裝(zhuang)(zhuang)無(wu)線(xian)充(chong)電(dian)技(ji)術,來(lai)自無(wu)線(xian)充(chong)電(dian)方案商向汽車主機廠提供(gong)的(de)(de)無(wu)線(xian)充(chong)電(dian)解決方案。一個(ge)合格的(de)(de)車載前裝(zhuang)(zhuang)無(wu)線(xian)充(chong)電(dian)要求具備基(ji)礎的(de)(de)無(wu)線(xian)充(chong)認證(zheng)、滿足嚴(yan)苛的(de)(de)車規級(ji)硬件標準,對(dui)工作溫度范圍、防水防塵等也(ye)有一定的(de)(de)等級(ji)要求。因此期安裝(zhuang)(zhuang)無(wu)線(xian)充(chong)電(dian)的(de)(de)廠家并不太多(duo)。
2、后裝無線車載充電器
后裝(zhuang)無(wu)線(xian)(xian)車(che)充是(shi)指原車(che)無(wu)無(wu)線(xian)(xian)充電器裝(zhuang)置(zhi),在汽車(che)上(shang)額(e)外加裝(zhuang)一個車(che)載支架等裝(zhuang)置(zhi)來實現無(wu)線(xian)(xian)充電,通常(chang)后裝(zhuang)的(de)無(wu)線(xian)(xian)車(che)充安(an)裝(zhuang)位(wei)置(zhi)不固定,可安(an)裝(zhuang)在空調通風口、汽車(che)中控臺等位(wei)置(zhi),或者(zhe)借(jie)助吸(xi)盤吸(xi)附在擋風玻(bo)璃上(shang)。
車載后裝(zhuang)無線充電,由于并(bing)不屬于整車的一部分,不受很多車廠(chang)強制性認證標準的約束,因此雖然(ran)產品可靠性不及前(qian)裝(zhuang),但勝在行業(ye)準入門(men)檻低(di)、產品性價比高。
