隨著電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)越來越多，充電(dian)(dian)樁(zhuang)的數量及擺放位(wei)置(zhi)不能滿足電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)車(che)(che)(che)主的用車(che)(che)(che)需(xu)求，電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)充電(dian)(dian)慢(man)續(xu)航短的問題(ti)愈加突出。而如果(guo)增加充電(dian)(dian)功(gong)率或使(shi)用一把以上充電(dian)(dian)槍就能解(jie)決(jue)電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)充電(dian)(dian)慢(man)的問題(ti)，延長電(dian)(dian)池(chi)的續(xu)航里程就能解(jie)決(jue)電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)續(xu)航短的問題(ti)。那么在當(dang)前電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)(che)相關技術(shu)的快速發展中，這(zhe)種假設有沒有辦法成為可(ke)能呢？

首先，我們(men)來(lai)看充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)速(su)度。解決電(dian)(dian)(dian)(dian)(dian)(dian)動車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)慢的(de)(de)方(fang)法一(yi)是(shi)(shi)增加(jia)電(dian)(dian)(dian)(dian)(dian)(dian)動功(gong)(gong)(gong)率(lv)，但電(dian)(dian)(dian)(dian)(dian)(dian)動槍(qiang)(qiang)(qiang)的(de)(de)重量(liang)是(shi)(shi)隨著電(dian)(dian)(dian)(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)越(yue)(yue)(yue)高就越(yue)(yue)(yue)大(da)的(de)(de)。如(ru)60KW的(de)(de)快充(chong)(chong)(chong)(chong)頭就重達幾斤，這還不算電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)的(de)(de)重量(liang)。由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)的(de)(de)截面越(yue)(yue)(yue)小電(dian)(dian)(dian)(dian)(dian)(dian)阻就越(yue)(yue)(yue)大(da)，產生的(de)(de)熱量(liang)就越(yue)(yue)(yue)高，所以為了安全起見(jian)，功(gong)(gong)(gong)率(lv)越(yue)(yue)(yue)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)就要(yao)越(yue)(yue)(yue)粗。那么加(jia)大(da)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)功(gong)(gong)(gong)率(lv)就會加(jia)重充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)(qiang)(qiang)整(zheng)體的(de)(de)重量(liang)，這對女(nv)性群體來(lai)說(shuo)具有拿不起充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)(qiang)(qiang)的(de)(de)可能(neng)性。方(fang)法二是(shi)(shi)增加(jia)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)口，如(ru)果使(shi)用一(yi)把(ba)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)(qiang)(qiang)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)需要(yao)1個(ge)(ge)小時，兩把(ba)槍(qiang)(qiang)(qiang)就可以縮短到(dao)(dao)30分(fen)鐘(zhong)，增加(jia)到(dao)(dao)5把(ba)槍(qiang)(qiang)(qiang)，10多(duo)分(fen)鐘(zhong)就可以充(chong)(chong)(chong)(chong)滿，且不存(cun)在會使(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)(qiang)(qiang)重量(liang)增加(jia)的(de)(de)問題。因此多(duo)槍(qiang)(qiang)(qiang)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)(shi)一(yi)個(ge)(ge)非常不錯的(de)(de)解決方(fang)案，尤其是(shi)(shi)對各種大(da)型的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)動重卡，多(duo)槍(qiang)(qiang)(qiang)模式能(neng)夠完美(mei)解決充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)慢的(de)(de)難題。其實，比亞迪早就使(shi)用了這個(ge)(ge)技術(shu)，其騰勢(shi)D9EV版車(che)型就有兩個(ge)(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)口，支持兩個(ge)(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)頭同(tong)時快充(chong)(chong)(chong)(chong)，電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)能(neng)夠從0到(dao)(dao)80%的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)縮短至40分(fen)鐘(zhong)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)15分(fen)鐘(zhong)可補充(chong)(chong)(chong)(chong)續航230公里。

接(jie)下(xia)來我(wo)們看電(dian)池(chi)續航(hang)。一(yi)般來說，電(dian)動汽(qi)車(che)目前使用的(de)電(dian)池(chi)是鋰(li)電(dian)池(chi)。這(zhe)種電(dian)池(chi)在(zai)冬季氣溫低至零度(du)或以下(xia)，它的(de)電(dian)解(jie)液會變得(de)濃稠，進(jin)而使得(de)電(dian)池(chi)的(de)運作速率(lv)變慢，降低電(dian)池(chi)在(zai)冬季的(de)續航(hang)能力，且(qie)(qie)它還有(you)(you)自燃(ran)的(de)風險。當(dang)前，寧德(de)時代研發出了一(yi)款(kuan)(kuan)續航(hang)突破1000公里的(de)麒(qi)麟電(dian)池(chi)，這(zhe)意味著在(zai)絕大(da)多數情況下(xia)電(dian)動汽(qi)車(che)不(bu)再需要(yao)中途充(chong)電(dian)。雖然這(zhe)款(kuan)(kuan)電(dian)池(chi)實(shi)現(xian)(xian)了電(dian)動汽(qi)車(che)續航(hang)能力的(de)較大(da)提升，但它的(de)價格(ge)太貴(gui)，一(yi)個麒(qi)麟電(dian)車(che)大(da)概需要(yao)10萬元左(zuo)右，且(qie)(qie)搭(da)載(zai)的(de)車(che)型基本在(zai)30萬以上(shang)，沒有(you)(you)辦法在(zai)市場(chang)上(shang)普及(ji)。而要(yao)徹底(di)解(jie)決電(dian)動汽(qi)車(che)的(de)續航(hang)問題，那就是搭(da)載(zai)固體電(dian)池(chi)。這(zhe)款(kuan)(kuan)電(dian)池(chi)沒有(you)(you)電(dian)解(jie)液，所以不(bu)受(shou)氣溫影響，也不(bu)會有(you)(you)自燃(ran)的(de)風險，不(bu)過固體電(dian)池(chi)至今還不(bu)能實(shi)現(xian)(xian)量產。

當(dang)(dang)前(qian)，對消費者來說，長途用(yong)(yong)油車沒(mei)有(you)續航焦慮(lv)(lv)，短(duan)(duan)途用(yong)(yong)電(dian)(dian)(dian)動(dong)汽(qi)車節約用(yong)(yong)車成(cheng)本(ben)，但電(dian)(dian)(dian)動(dong)汽(qi)車的充電(dian)(dian)(dian)慢續航短(duan)(duan)問題確(que)實(shi)令人頭大。然而當(dang)(dang)快充技術與固態電(dian)(dian)(dian)池(chi)搭(da)配(pei)使用(yong)(yong)，或將可以讓電(dian)(dian)(dian)動(dong)汽(qi)車再(zai)沒(mei)有(you)續航焦慮(lv)(lv)和補(bu)能焦慮(lv)(lv)。
