一種快速直流電池充電器正登陸美國電(dian)(dian)(dian)動汽(qi)車(che)市場，這種充電(dian)(dian)(dian)器(qi)能夠在20分(fen)鐘內為電(dian)(dian)(dian)動車(che)充滿(man)80%的(de)電(dian)(dian)(dian)量(liang)。消(xiao)費者(zhe)未來(lai)有望以低廉的(de)價格(ge)在數分(fen)鐘內完成電(dian)(dian)(dian)動車(che)充電(dian)(dian)(dian)，而電(dian)(dian)(dian)能儲存則(ze)是(shi)實現這一目標的(de)關鍵點。

　　快(kuai)速(su)充(chong)電(dian)器無(wu)疑為(wei)純電(dian)動(dong)(dong)汽車(che)(che)的發展(zhan)提供了便利，但(dan)電(dian)動(dong)(dong)汽車(che)(che)的充(chong)電(dian)高峰時段很有可能給電(dian)網帶來巨大壓(ya)力，如果電(dian)動(dong)(dong)車(che)(che)充(chong)電(dian)業(ye)務選(xuan)擇使(shi)用(yong)(yong)高電(dian)價的峰時電(dian)充(chong)電(dian),一天(tian)的費用(yong)(yong)將(jiang)高達(da)數(shu)百甚至數(shu)千(qian)美(mei)元。

　　因此(ci)，發展快速直(zhi)流充(chong)電(dian)(dian)(dian)站，必須避(bi)免峰時(shi)充(chong)電(dian)(dian)(dian)的問題(ti)，因為電(dian)(dian)(dian)動汽車此(ci)時(shi)在快速站充(chong)電(dian)(dian)(dian)將耗(hao)電(dian)(dian)(dian)50千瓦(wa)，是“慢速”充(chong)電(dian)(dian)(dian)站耗(hao)電(dian)(dian)(dian)量(liang)的15倍。

　　事(shi)實上，自直流(liu)充電(dian)(dian)器計劃推出以來，電(dian)(dian)池(chi)(chi)生(sheng)產廠家就(jiu)致力于開(kai)發對電(dian)(dian)網壓力較小的電(dian)(dian)池(chi)(chi)產品。例如，美國(guo)電(dian)(dian)動汽車服務商350Green已經在芝(zhi)加哥開(kai)始發展鋰離子電(dian)(dian)池(chi)(chi)的快(kuai)速充電(dian)(dian)器，并與韓國(guo)方面(mian)開(kai)展合(he)作，建立智能電(dian)(dian)網中心，其中即包括芝(zhi)加哥的280 AC和(he)快(kuai)速的安裝(zhuang)工作。

　　同(tong)時(shi)，350Green已經建成一座電(dian)(dian)池(chi)包組裝廠，以(yi)期將電(dian)(dian)動(dong)汽車充電(dian)(dian)產業(ye)延伸至全(quan)美(mei)。350Green的(de)CEO馬里亞納(Mariana Gerzanych)介紹(shao)，相關電(dian)(dian)池(chi)產品來自(zi)芝加哥伊(yi)利諾理工大學(Illinois Institute of Technology)及其下設的(de)AllCell科技公司(AllCell Technologie)。

　　馬(ma)里亞納稱，350Green電池(chi)包組(zu)裝(zhuang)業務并非限定于特定電池(chi)供(gong)應商。2012年8月，350Green電池(chi)組(zu)裝(zhuang)廠(chang)將(jiang)投產，本(ben)年度電池(chi)包組(zu)裝(zhuang)量達3兆(zhao)。
