一、車載無線充電器的弊端有哪些

車載充電是許多車主都有的需求，一些汽車生產廠商在生產汽車時甚至會預安裝車載無線充電器，無線車載充電器雖然使用起(qi)來比(bi)較方(fang)便，但是(shi)它(ta)也存在(zai)一定的弊(bi)端：

1、兼容性問題

無線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)國際標(biao)準(zhun)(zhun)有兩(liang)個(ge)，一個(ge)叫Qi，另一個(ge)叫rezence，這兩(liang)個(ge)陣營的(de)(de)無線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)標(biao)準(zhun)(zhun)是(shi)互(hu)相不兼容的(de)(de)，如果要解決兼容性問題，就(jiu)需要在無線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)座(zuo)上把兩(liang)個(ge)標(biao)準(zhun)(zhun)的(de)(de)技術都(dou)集成進去。因此并不是(shi)所有支(zhi)持無線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)設備，都(dou)可以在任何一臺搭(da)載無線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技術的(de)(de)車(che)輛(liang)上進行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)。

2、效率問題

無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)受制于(yu)技(ji)術的(de)(de)(de)發展，充(chong)電(dian)(dian)效率還比較(jiao)(jiao)差，因為(wei)(wei)無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)本(ben)身(shen)的(de)(de)(de)功率較(jiao)(jiao)小，并且實際表現不大穩定。無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)實際上是利(li)用手(shou)機背(bei)板(ban)的(de)(de)(de)無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)線(xian)(xian)(xian)圈(quan)來達到的(de)(de)(de)，車載無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)器為(wei)(wei)了(le)適(shi)配市面(mian)上主流的(de)(de)(de)所有手(shou)機，會將無(wu)線(xian)(xian)(xian)充(chong)電(dian)(dian)槽(cao)做的(de)(de)(de)特(te)別大，相對較(jiao)(jiao)小的(de)(de)(de)手(shou)機在充(chong)電(dian)(dian)槽(cao)里就會滑(hua)來滑(hua)去，影響(xiang)了(le)線(xian)(xian)(xian)圈(quan)的(de)(de)(de)對準，降低充(chong)電(dian)(dian)的(de)(de)(de)效率。

3、電池問題

總所(suo)周知，手機電(dian)(dian)(dian)池(chi)(chi)(chi)的衰(shuai)減(jian)(jian)是(shi)根(gen)據充電(dian)(dian)(dian)的循環(huan)次(ci)數(shu)逐步增加的，研(yan)究(jiu)表明，無(wu)線充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)循環(huan)的次(ci)數(shu)要(yao)遠遠大(da)于(yu)有線充電(dian)(dian)(dian)，大(da)概比(bi)有線充電(dian)(dian)(dian)快2.5倍左(zuo)右，這會導致無(wu)線充電(dian)(dian)(dian)的手機電(dian)(dian)(dian)池(chi)(chi)(chi)衰(shuai)減(jian)(jian)更快，使用壽命更短。

4、發熱問題

無線(xian)(xian)充電過程中的發(fa)熱是(shi)避免不了的，因為能量(liang)在轉(zhuan)化時都會伴隨(sui)著損耗，而(er)此類損耗通常就是(shi)以熱能的形(xing)(xing)式散發(fa)。手(shou)機無線(xian)(xian)充電要(yao)經(jing)歷電磁之(zhi)間的兩次能量(liang)轉(zhuan)化，所以其發(fa)熱量(liang)要(yao)比有線(xian)(xian)充電高得多(duo)，大概(gai)有25%左右都要(yao)以熱量(liang)的形(xing)(xing)式散發(fa)掉，這也是(shi)充電效率低(di)的原因之(zhi)一。

5、使用沖突

對于許多用Cariplay的(de)朋友來說，無線(xian)(xian)充(chong)(chong)電(dian)(dian)是(shi)比較雞(ji)肋的(de)，因為只有少數(shu)的(de)車型支(zhi)持無線(xian)(xian)CarPlay，大部分車輛(liang)使用CarPlay時(shi)都(dou)需要有線(xian)(xian)連(lian)接(jie)(jie)。在有線(xian)(xian)連(lian)接(jie)(jie)CarPlay時(shi)，車輛(liang)也會同時(shi)為手(shou)機(ji)充(chong)(chong)電(dian)(dian)，由于手(shou)機(ji)不(bu)支(zhi)持同時(shi)使用兩種充(chong)(chong)電(dian)(dian)方式，這也就意味著(zhu)，即(ji)便我們插著(zhu)數(shu)據線(xian)(xian)將手(shou)機(ji)放置到無線(xian)(xian)充(chong)(chong)電(dian)(dian)區(qu)域時(shi)，無線(xian)(xian)充(chong)(chong)電(dian)(dian)也是(shi)不(bu)起作用的(de)。

二、車載無線充電器傷手機嗎

無線車(che)(che)充(chong)傷手(shou)機(ji)嗎(ma)？盡(jin)管車(che)(che)載無線充(chong)電(dian)(dian)器存在一定的弊端，但車(che)(che)載無線充(chong)電(dian)(dian)器對手(shou)機(ji)的傷害是并不(bu)大(da)的，正常情況下(xia)(xia)基本(ben)沒什么(me)影響，因為車(che)(che)載無線充(chong)電(dian)(dian)器的工作頻率(lv)基本(ben)在1M以下(xia)(xia)，所(suo)以對手(shou)機(ji)的信(xin)號不(bu)會有影響。

并且無線(xian)充電(dian)器主(zhu)要(yao)采用的(de)是電(dian)感耦合技術，因為(wei)耦合技術，主(zhu)要(yao)通過的(de)是線(xian)圈的(de)磁場產生電(dian)流，電(dian)池(chi)內部成(cheng)分(fen)本身不能構(gou)成(cheng)磁場，所以在通電(dian)過程中就不會損害(hai)到電(dian)池(chi)的(de)內部結構(gou)。

總的來說，正規廠家生產的無線車載充電器內(nei)置有諸多(duo)保護功能，其對于(yu)手機(ji)的損傷(shang)是(shi)幾乎(hu)可(ke)以(yi)忽略(lve)不計的，大家(jia)可(ke)以(yi)放心使用。
