1)電(dian)池快充(chong)的(de)技術難點(dian)：能做到20分鐘充(chong)滿電(dian)，電(dian)動汽車的(de)市(shi)場競爭(zheng)力將(jiang)會明顯提升。其(qi)難點(dian)是：
a)要(yao)有能接(jie)受快(kuai)充(chong)(chong)的電(dian)(dian)(dian)池。前磷酸(suan)鐵鋰鋰離(li)子電(dian)(dian)(dian)池來說(shuo)是可能的3CA的充(chong)(chong)電(dian)(dian)(dian)倍率進行(xing)充(chong)(chong)電(dian)(dian)(dian)，鈦(tai)酸(suan)鋰電(dian)(dian)(dian)池可以接(jie)受更高的10CA的充(chong)(chong)電(dian)(dian)(dian)倍率進行(xing)充(chong)(chong)電(dian)(dian)(dian)。
b)20分(fen)鐘充(chong)滿電(dian)(dian)，那至少要(yao)用3CA的(de)充(chong)電(dian)(dian)倍(bei)率進行充(chong)電(dian)(dian)，電(dian)(dian)池組導(dao)線及接(jie)頭的(de)容量(liang)至少要(yao)增加(jia)5倍(bei)以上，如何解決？
c)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設備所需(xu)的功(gong)率很大。以(yi)一輛電(dian)(dian)(dian)(dian)(dian)動(dong)大巴為(wei)例，它配(pei)置600Ah的電(dian)(dian)(dian)(dian)(dian)池120個。3CA的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流為(wei)1800A，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓510V。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器的輸(shu)出功(gong)率為(wei)918kw，電(dian)(dian)(dian)(dian)(dian)網提供(gong)的功(gong)率1150kw，如何解(jie)決？
2)電池快換(huan)的技術(shu)(shu)難點：換(huan)一次(ci)電池的時間大約需要10分(fen)鐘，大眾(zhong)是滿意度(du)，但(dan)是其技術(shu)(shu)難點是：
a)用快速(su)更換法時(shi)，要求電(dian)池(chi)組(zu)的(de)容量減(jian)半。這樣一來，電(dian)池(chi)的(de)放電(dian)倍率增(zeng)加一倍，會使(shi)電(dian)池(chi)的(de)壽命減(jian)少(shao)。
b)用(yong)快速更換(huan)法(fa)時，對電池(chi)組的標(biao)準化設計和電池(chi)的一(yi)致性、充電控制要求更高(gao)，增加(jia)電動車的運行成(cheng)本。
c)如果仍然保持電(dian)(dian)池(chi)合理的配置，那(nei)么也要增加(jia)(jia)一倍的電(dian)(dian)池(chi)儲備，自然會(hui)增加(jia)(jia)電(dian)(dian)動車的運行(xing)成(cheng)本。
