隨著(zhu)電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)越(yue)來越(yue)多，充(chong)電(dian)樁的(de)數量及擺放位置(zhi)不能(neng)滿(man)足電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)車(che)(che)(che)(che)主的(de)用(yong)車(che)(che)(che)(che)需(xu)求，電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)充(chong)電(dian)慢(man)續(xu)航(hang)短的(de)問(wen)題(ti)愈加突(tu)出。而(er)如果增加充(chong)電(dian)功率或使(shi)用(yong)一把以上充(chong)電(dian)槍就能(neng)解決(jue)電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)充(chong)電(dian)慢(man)的(de)問(wen)題(ti)，延長(chang)電(dian)池(chi)的(de)續(xu)航(hang)里程就能(neng)解決(jue)電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)續(xu)航(hang)短的(de)問(wen)題(ti)。那么在當前電(dian)動(dong)(dong)汽(qi)車(che)(che)(che)(che)相(xiang)關技術的(de)快速發展(zhan)中，這種假設有(you)沒有(you)辦法成為可能(neng)呢？

首先，我們來看(kan)充(chong)(chong)電(dian)(dian)(dian)速度。解決(jue)電(dian)(dian)(dian)動(dong)車(che)充(chong)(chong)電(dian)(dian)(dian)慢(man)的方(fang)法(fa)一是(shi)增加(jia)(jia)(jia)電(dian)(dian)(dian)動(dong)功率，但(dan)電(dian)(dian)(dian)動(dong)槍(qiang)的重(zhong)(zhong)量是(shi)隨著電(dian)(dian)(dian)功率越(yue)高就(jiu)(jiu)(jiu)越(yue)大(da)(da)的。如(ru)60KW的快(kuai)充(chong)(chong)頭就(jiu)(jiu)(jiu)重(zhong)(zhong)達幾(ji)斤，這(zhe)還不算電(dian)(dian)(dian)線的重(zhong)(zhong)量。由于電(dian)(dian)(dian)線的截面越(yue)小電(dian)(dian)(dian)阻(zu)就(jiu)(jiu)(jiu)越(yue)大(da)(da)，產生的熱量就(jiu)(jiu)(jiu)越(yue)高，所以(yi)為了安全起見，功率越(yue)大(da)(da)電(dian)(dian)(dian)線就(jiu)(jiu)(jiu)要(yao)越(yue)粗。那么加(jia)(jia)(jia)大(da)(da)充(chong)(chong)電(dian)(dian)(dian)功率就(jiu)(jiu)(jiu)會(hui)加(jia)(jia)(jia)重(zhong)(zhong)充(chong)(chong)電(dian)(dian)(dian)槍(qiang)整體的重(zhong)(zhong)量，這(zhe)對女性群體來說具有(you)拿不起充(chong)(chong)電(dian)(dian)(dian)槍(qiang)的可(ke)能(neng)性。方(fang)法(fa)二是(shi)增加(jia)(jia)(jia)充(chong)(chong)電(dian)(dian)(dian)口(kou)，如(ru)果使(shi)用一把充(chong)(chong)電(dian)(dian)(dian)槍(qiang)充(chong)(chong)電(dian)(dian)(dian)需要(yao)1個小時(shi)，兩把槍(qiang)就(jiu)(jiu)(jiu)可(ke)以(yi)縮短到(dao)30分鐘(zhong)，增加(jia)(jia)(jia)到(dao)5把槍(qiang)，10多(duo)分鐘(zhong)就(jiu)(jiu)(jiu)可(ke)以(yi)充(chong)(chong)滿，且不存在會(hui)使(shi)充(chong)(chong)電(dian)(dian)(dian)槍(qiang)重(zhong)(zhong)量增加(jia)(jia)(jia)的問題。因此多(duo)槍(qiang)充(chong)(chong)電(dian)(dian)(dian)是(shi)一個非常不錯的解決(jue)方(fang)案(an)，尤其是(shi)對各(ge)種(zhong)大(da)(da)型的電(dian)(dian)(dian)動(dong)重(zhong)(zhong)卡，多(duo)槍(qiang)模式能(neng)夠完美解決(jue)充(chong)(chong)電(dian)(dian)(dian)慢(man)的難題。其實，比亞迪早(zao)就(jiu)(jiu)(jiu)使(shi)用了這(zhe)個技術(shu)，其騰勢(shi)D9EV版車(che)型就(jiu)(jiu)(jiu)有(you)兩個充(chong)(chong)電(dian)(dian)(dian)口(kou)，支持兩個充(chong)(chong)電(dian)(dian)(dian)頭同時(shi)快(kuai)充(chong)(chong)，電(dian)(dian)(dian)量能(neng)夠從0到(dao)80%的充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)縮短至40分鐘(zhong)，充(chong)(chong)電(dian)(dian)(dian)15分鐘(zhong)可(ke)補充(chong)(chong)續航230公里。

接下來(lai)我們看電(dian)(dian)(dian)(dian)(dian)池續(xu)航(hang)(hang)。一(yi)般來(lai)說，電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)目(mu)前使用的(de)(de)電(dian)(dian)(dian)(dian)(dian)池是(shi)鋰電(dian)(dian)(dian)(dian)(dian)池。這(zhe)種電(dian)(dian)(dian)(dian)(dian)池在(zai)(zai)(zai)冬(dong)季氣溫(wen)低(di)至(zhi)零度或以下，它的(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)液會變(bian)(bian)得(de)濃稠(chou)，進而使得(de)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)運作(zuo)速率變(bian)(bian)慢，降(jiang)低(di)電(dian)(dian)(dian)(dian)(dian)池在(zai)(zai)(zai)冬(dong)季的(de)(de)續(xu)航(hang)(hang)能力，且它還有(you)(you)自燃的(de)(de)風險。當(dang)前，寧(ning)德時(shi)代研(yan)發(fa)出(chu)了(le)一(yi)款續(xu)航(hang)(hang)突破1000公里(li)的(de)(de)麒(qi)麟(lin)電(dian)(dian)(dian)(dian)(dian)池，這(zhe)意味著在(zai)(zai)(zai)絕大多數情況下電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)不(bu)再需要中途充(chong)電(dian)(dian)(dian)(dian)(dian)。雖然這(zhe)款電(dian)(dian)(dian)(dian)(dian)池實現(xian)了(le)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)續(xu)航(hang)(hang)能力的(de)(de)較大提升，但它的(de)(de)價格太貴(gui)，一(yi)個麒(qi)麟(lin)電(dian)(dian)(dian)(dian)(dian)車(che)大概需要10萬元(yuan)左右，且搭(da)載的(de)(de)車(che)型基本在(zai)(zai)(zai)30萬以上，沒(mei)有(you)(you)辦法在(zai)(zai)(zai)市場上普及(ji)。而要徹(che)底(di)解(jie)決電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)的(de)(de)續(xu)航(hang)(hang)問題，那就是(shi)搭(da)載固體電(dian)(dian)(dian)(dian)(dian)池。這(zhe)款電(dian)(dian)(dian)(dian)(dian)池沒(mei)有(you)(you)電(dian)(dian)(dian)(dian)(dian)解(jie)液，所以不(bu)受氣溫(wen)影(ying)響，也不(bu)會有(you)(you)自燃的(de)(de)風險，不(bu)過固體電(dian)(dian)(dian)(dian)(dian)池至(zhi)今還不(bu)能實現(xian)量(liang)產。

當(dang)前，對消費者來說，長途用(yong)(yong)油(you)車(che)沒有(you)續(xu)航焦慮(lv)，短途用(yong)(yong)電(dian)動(dong)汽(qi)車(che)節約(yue)用(yong)(yong)車(che)成(cheng)本，但(dan)電(dian)動(dong)汽(qi)車(che)的充電(dian)慢續(xu)航短問題確實令人(ren)頭大。然(ran)而當(dang)快充技(ji)術與固態電(dian)池搭配使用(yong)(yong)，或將可以讓電(dian)動(dong)汽(qi)車(che)再沒有(you)續(xu)航焦慮(lv)和補能焦慮(lv)。
