1)電池(chi)快充的技術難點(dian)(dian)：能(neng)做到20分鐘充滿電，電動(dong)汽車(che)的市(shi)場(chang)競爭力將會明顯提升。其(qi)難點(dian)(dian)是：
a)要有(you)能接(jie)受快(kuai)充的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。前磷酸(suan)鐵(tie)鋰鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)來(lai)說是可(ke)能的(de)3CA的(de)充電(dian)(dian)(dian)(dian)倍(bei)率進行(xing)充電(dian)(dian)(dian)(dian)，鈦酸(suan)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)可(ke)以接(jie)受更高的(de)10CA的(de)充電(dian)(dian)(dian)(dian)倍(bei)率進行(xing)充電(dian)(dian)(dian)(dian)。
b)20分鐘(zhong)充滿電(dian)(dian)，那至少要(yao)用3CA的充電(dian)(dian)倍率進行充電(dian)(dian)，電(dian)(dian)池組導線(xian)及接頭的容量至少要(yao)增加5倍以上，如何解決？
c)充(chong)(chong)電(dian)(dian)設備所需的功率(lv)很大。以一輛電(dian)(dian)動大巴為(wei)例，它配置600Ah的電(dian)(dian)池120個。3CA的充(chong)(chong)電(dian)(dian)電(dian)(dian)流為(wei)1800A，充(chong)(chong)電(dian)(dian)電(dian)(dian)壓510V。充(chong)(chong)電(dian)(dian)器的輸出功率(lv)為(wei)918kw，電(dian)(dian)網提供(gong)的功率(lv)1150kw，如(ru)何(he)解決？
2)電(dian)池快換的技(ji)術難點：換一次電(dian)池的時(shi)間大約需要10分鐘，大眾是(shi)滿意度，但是(shi)其技(ji)術難點是(shi)：
a)用快速(su)更換(huan)法時，要求電(dian)(dian)池組的(de)容量減半。這樣(yang)一(yi)來(lai)，電(dian)(dian)池的(de)放電(dian)(dian)倍率增(zeng)加一(yi)倍，會使電(dian)(dian)池的(de)壽命減少。
b)用快速(su)更(geng)換法時(shi)，對電(dian)池(chi)組(zu)的(de)(de)標準(zhun)化設計和電(dian)池(chi)的(de)(de)一致性、充電(dian)控制要求更(geng)高(gao)，增(zeng)加電(dian)動(dong)車的(de)(de)運行(xing)成(cheng)本(ben)。
c)如果仍然(ran)保持電(dian)(dian)池(chi)(chi)合理的配置，那(nei)么(me)也要增(zeng)(zeng)加(jia)一倍的電(dian)(dian)池(chi)(chi)儲備，自然(ran)會增(zeng)(zeng)加(jia)電(dian)(dian)動車的運行成本(ben)。
