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(sui)然(ran)使用起來(lai)比較方便，但是它也存(cun)在一定(ding)的(de)弊端：

1、兼容性問題

無(wu)(wu)線充(chong)電(dian)(dian)國際標(biao)(biao)準(zhun)(zhun)有(you)兩(liang)(liang)個，一個叫Qi，另一個叫rezence，這兩(liang)(liang)個陣營的(de)(de)無(wu)(wu)線充(chong)電(dian)(dian)標(biao)(biao)準(zhun)(zhun)是互相(xiang)不兼(jian)容(rong)的(de)(de)，如果要解決兼(jian)容(rong)性(xing)問題，就需要在無(wu)(wu)線充(chong)電(dian)(dian)座上把兩(liang)(liang)個標(biao)(biao)準(zhun)(zhun)的(de)(de)技(ji)術(shu)都(dou)(dou)集成進去(qu)。因此并不是所有(you)支持無(wu)(wu)線充(chong)電(dian)(dian)的(de)(de)設備，都(dou)(dou)可以在任何一臺(tai)搭載無(wu)(wu)線充(chong)電(dian)(dian)技(ji)術(shu)的(de)(de)車輛上進行充(chong)電(dian)(dian)的(de)(de)。

2、效率問題

無線(xian)(xian)充(chong)(chong)電(dian)受制于(yu)技術的(de)(de)(de)(de)發展，充(chong)(chong)電(dian)效率(lv)還(huan)比較(jiao)(jiao)差，因為(wei)無線(xian)(xian)充(chong)(chong)電(dian)本身(shen)的(de)(de)(de)(de)功(gong)率(lv)較(jiao)(jiao)小，并且實際表現(xian)不大穩定。無線(xian)(xian)充(chong)(chong)電(dian)實際上(shang)(shang)是利用手(shou)機背板(ban)的(de)(de)(de)(de)無線(xian)(xian)充(chong)(chong)電(dian)線(xian)(xian)圈來(lai)達到的(de)(de)(de)(de)，車(che)載(zai)無線(xian)(xian)充(chong)(chong)電(dian)器為(wei)了適(shi)配市面上(shang)(shang)主流的(de)(de)(de)(de)所有手(shou)機，會將無線(xian)(xian)充(chong)(chong)電(dian)槽做的(de)(de)(de)(de)特別大，相對較(jiao)(jiao)小的(de)(de)(de)(de)手(shou)機在充(chong)(chong)電(dian)槽里(li)就會滑(hua)來(lai)滑(hua)去，影響了線(xian)(xian)圈的(de)(de)(de)(de)對準，降低(di)充(chong)(chong)電(dian)的(de)(de)(de)(de)效率(lv)。

3、電池問題

總(zong)所周知，手(shou)(shou)機電(dian)(dian)(dian)(dian)池(chi)的(de)(de)衰(shuai)減是根據(ju)充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)循環次數(shu)(shu)逐步(bu)增加的(de)(de)，研究表明，無線(xian)(xian)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)循環的(de)(de)次數(shu)(shu)要遠(yuan)遠(yuan)大于有線(xian)(xian)充(chong)(chong)電(dian)(dian)(dian)(dian)，大概比有線(xian)(xian)充(chong)(chong)電(dian)(dian)(dian)(dian)快(kuai)2.5倍左右(you)，這會導致無線(xian)(xian)充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)手(shou)(shou)機電(dian)(dian)(dian)(dian)池(chi)衰(shuai)減更快(kuai)，使用壽(shou)命更短。

4、發熱問題

無線(xian)充(chong)電過程(cheng)中(zhong)的(de)發熱(re)是(shi)避免不(bu)了(le)的(de)，因為能量(liang)在(zai)轉化時都(dou)會伴隨(sui)著損耗(hao)(hao)，而(er)此類(lei)損耗(hao)(hao)通常就是(shi)以(yi)熱(re)能的(de)形(xing)(xing)式(shi)散發。手機無線(xian)充(chong)電要(yao)(yao)經歷電磁(ci)之(zhi)間(jian)的(de)兩(liang)次(ci)能量(liang)轉化，所(suo)以(yi)其發熱(re)量(liang)要(yao)(yao)比有(you)(you)線(xian)充(chong)電高得多，大概(gai)有(you)(you)25%左右都(dou)要(yao)(yao)以(yi)熱(re)量(liang)的(de)形(xing)(xing)式(shi)散發掉(diao)，這也是(shi)充(chong)電效率低(di)的(de)原因之(zhi)一(yi)。

5、使用沖突

對于許多用(yong)(yong)Cariplay的(de)朋友(you)來說，無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)是(shi)比(bi)較雞肋的(de)，因為(wei)只(zhi)有少數的(de)車型支(zhi)持無(wu)(wu)線(xian)CarPlay，大部分(fen)車輛使用(yong)(yong)CarPlay時(shi)都需(xu)要有線(xian)連接。在(zai)有線(xian)連接CarPlay時(shi)，車輛也(ye)(ye)會同時(shi)為(wei)手(shou)機充(chong)(chong)(chong)電(dian)，由(you)于手(shou)機不(bu)支(zhi)持同時(shi)使用(yong)(yong)兩種充(chong)(chong)(chong)電(dian)方式，這也(ye)(ye)就意味著，即便我們插著數據(ju)線(xian)將(jiang)手(shou)機放置到無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)區域時(shi)，無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)也(ye)(ye)是(shi)不(bu)起作用(yong)(yong)的(de)。

二、車載無線充電器傷手機嗎

無(wu)線(xian)車充傷(shang)手(shou)機嗎？盡管車載(zai)無(wu)線(xian)充電器(qi)存在一定(ding)的(de)(de)弊(bi)端，但(dan)車載(zai)無(wu)線(xian)充電器(qi)對(dui)手(shou)機的(de)(de)傷(shang)害是(shi)并不大的(de)(de)，正常情況下基(ji)本沒什(shen)么影響，因為車載(zai)無(wu)線(xian)充電器(qi)的(de)(de)工作(zuo)頻率基(ji)本在1M以(yi)下，所以(yi)對(dui)手(shou)機的(de)(de)信(xin)號不會(hui)有影響。

并且無線充電(dian)(dian)(dian)器主要(yao)采用的是(shi)(shi)電(dian)(dian)(dian)感(gan)耦合技術(shu)，因(yin)為耦合技術(shu)，主要(yao)通過的是(shi)(shi)線圈(quan)的磁場(chang)產(chan)生電(dian)(dian)(dian)流，電(dian)(dian)(dian)池內(nei)(nei)部(bu)(bu)成(cheng)分本身不能構(gou)成(cheng)磁場(chang)，所以在通電(dian)(dian)(dian)過程中(zhong)就不會損害到電(dian)(dian)(dian)池的內(nei)(nei)部(bu)(bu)結(jie)構(gou)。

總的來說，正規廠家生產的無線車載充電器內置有諸多(duo)保護(hu)功能(neng)，其(qi)對于手機的損傷(shang)是幾乎可(ke)以(yi)忽略不計(ji)的，大家(jia)可(ke)以(yi)放(fang)心使(shi)用。
