隨著電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)市(shi)場不斷升溫，動(dong)力電(dian)(dian)(dian)(dian)池相(xiang)關技(ji)術也成(cheng)為國(guo)內外(wai)汽(qi)(qi)車(che)廠商(shang)發(fa)力的(de)重(zhong)點。為了促進(jin)電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)的(de)普及，爭奪下一代技(ji)術主導權，縮短充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)很有必要，尤其是在(zai)(zai)高續駛(shi)里(li)程電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)紛紛上市(shi)的(de)情況下。如何讓充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)可與加油時間(jian)相(xiang)媲(pi)美一直是汽(qi)(qi)車(che)廠商(shang)努力的(de)目標。據外(wai)媒日前(qian)(qian)報道，通(tong)用汽(qi)(qi)車(che)正(zheng)在(zai)(zai)與合作伙伴Delta Americas共同(tong)開發(fa)電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)系統，目標是讓電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)10分鐘可行駛(shi)180英里(li)（約合290公里(li)）。如果這一技(ji)術成(cheng)功，那(nei)么將比特斯拉以及保時捷(jie)當前(qian)(qian)的(de)超(chao)級快充(chong)(chong)(chong)技(ji)術效率更高。

■ 普及電動汽(qi)車要靠快充(chong)

通用與Delta Americas正在開(kai)展的合作項目(mu)(mu)為期三年，總投(tou)資700萬美元，目(mu)(mu)標(biao)是共同開(kai)發(fa)400kW超快速充電系(xi)(xi)統(tong)（XFC）。據介紹，該系(xi)(xi)統(tong)基(ji)于固態變壓器（SST）技術開(kai)發(fa)，重量是普(pu)通直流快速充電系(xi)(xi)統(tong)的1/4，尺寸則是其一(yi)半。接口方面，采用美國(guo)汽車工程師學會(hui)（SAE）主(zhu)導的“聯合充電系(xi)(xi)統(tong)（CCS）”標(biao)準。

同時(shi)，這套超(chao)快速充(chong)電(dian)(dian)系統的傳輸(shu)效(xiao)(xiao)(xiao)率有望達(da)到96.5％，每(mei)分鐘充(chong)的電(dian)(dian)可供(gong)電(dian)(dian)動汽車行駛29公里(li)。與之相比，特(te)斯拉超(chao)級充(chong)電(dian)(dian)系統的效(xiao)(xiao)(xiao)率為每(mei)分鐘10公里(li)，而保(bao)時(shi)捷承諾為Taycan電(dian)(dian)動跑車提供(gong)的充(chong)電(dian)(dian)效(xiao)(xiao)(xiao)率是每(mei)分鐘約20公里(li)。

通(tong)用(yong)(yong)(yong)認為，此舉將(jiang)有利于電動(dong)(dong)汽(qi)車(che)的(de)(de)推(tui)廣(guang)。當前，各大主流汽(qi)車(che)廠商相繼發(fa)布了(le)雄(xiong)心勃(bo)勃(bo)的(de)(de)電動(dong)(dong)汽(qi)車(che)推(tui)廣(guang)計劃，通(tong)用(yong)(yong)(yong)也(ye)不例(li)外。去年(nian)10月(yue)，通(tong)用(yong)(yong)(yong)宣布將(jiang)加快其(qi)電動(dong)(dong)化進程。當時的(de)(de)說(shuo)法是(shi)(shi)“未來18個月(yue)內，通(tong)用(yong)(yong)(yong)將(jiang)基于Bolt所使用(yong)(yong)(yong)的(de)(de)純電動(dong)(dong)車(che)平臺，推(tui)出(chu)兩款新型電動(dong)(dong)汽(qi)車(che)。未來5年(nian)內，將(jiang)新增18款電動(dong)(dong)汽(qi)車(che)。”也(ye)就是(shi)(shi)說(shuo)，到2023年(nian)，通(tong)用(yong)(yong)(yong)將(jiang)在(zai)全球至少銷售20款具備(bei)快速充電能力(li)的(de)(de)電動(dong)(dong)汽(qi)車(che)。

Navigant Research咨(zi)詢機構公(gong)司分析師薩(sa)姆(mu)·阿布薩(sa)米德表示(shi)：“在給(gei)電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)充(chong)電(dian)(dian)(dian)時，每個人(ren)都希(xi)望(wang)能(neng)和(he)燃油(you)車(che)加油(you)一樣(yang)(yang)快。對于生活在城(cheng)市里的(de)人(ren)來說(shuo)尤(you)為如此。”的(de)確，要普及電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)，必(bi)須解決消費者的(de)“里程焦慮癥(zheng)”。一方面(mian)，汽(qi)(qi)車(che)廠商要不(bu)斷推出(chu)續駛里程更長的(de)新一代產品；另(ling)一方面(mian)，要讓電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)充(chong)電(dian)(dian)(dian)能(neng)像燃油(you)車(che)加油(you)一樣(yang)(yang)便利。這就(jiu)需要雙管齊下(xia)，除了布局(ju)健(jian)全的(de)充(chong)電(dian)(dian)(dian)樁網絡外，縮短(duan)充(chong)電(dian)(dian)(dian)時間也非(fei)常關鍵。
