電(dian)池從(cong)電(dian)源供(gong)電(dian)系統中下線進行充(chong)電(dian)，可(ke)以在(zai)很短的時間內補充(chong)電(dian)池所需要的電(dian)能(neng)，這種方法就叫(jiao)做(zuo)快(kuai)速充(chong)電(dian)。
快速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)也采用限(xian)(xian)流(liu)恒(heng)(heng)壓(ya)(ya)(ya)(ya)式，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)可(ke)以在十二個小(xiao)時之內完成，這(zhe)幾種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方法包(bao)含(han)限(xian)(xian)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)和(he)恒(heng)(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)兩個階段，如果只是(shi)恒(heng)(heng)壓(ya)(ya)(ya)(ya)不限(xian)(xian)流(liu)，對電(dian)(dian)(dian)(dian)池損壞會(hui)(hui)很大(da)。因為恒(heng)(heng)壓(ya)(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)初期充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)會(hui)(hui)特別大(da)，過大(da)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)使電(dian)(dian)(dian)(dian)極(ji)上活性物質小(xiao)孔中電(dian)(dian)(dian)(dian)解(jie)液(ye)濃度(du)(du)升高，而電(dian)(dian)(dian)(dian)解(jie)液(ye)的(de)擴(kuo)散(san)速(su)度(du)(du)沒有濃差極(ji)化(hua)(hua)和(he)電(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)極(ji)化(hua)(hua)的(de)綜合(he)速(su)度(du)(du)的(de)要(yao)求，會(hui)(hui)產生非常(chang)高的(de)電(dian)(dian)(dian)(dian)位趨勢，這(zhe)時充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值就(jiu)恒(heng)(heng)定了，就(jiu)會(hui)(hui)轉化(hua)(hua)為充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)流(liu)。
在充(chong)(chong)(chong)電(dian)(dian)初期充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)過大(da)(da)的時候，正極活(huo)性(xing)物(wu)質會和(he)負極活(huo)性(xing)物(wu)質會有很(hen)細很(hen)密的晶體微粒(li)，會影(ying)響充(chong)(chong)(chong)電(dian)(dian)的深度。另外在充(chong)(chong)(chong)電(dian)(dian)初期要(yao)實現大(da)(da)電(dian)(dian)流(liu)需(xu)要(yao)大(da)(da)功率充(chong)(chong)(chong)電(dian)(dian)設備(bei)，因此充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)要(yao)限(xian)流(liu)。電(dian)(dian)流(liu)的功率和(he)哪些(xie)因素有關(guan)呢？
電池正極(ji)上活性物質的(de)厚度(du)和孔率。如(ru)果(guo)活性物質孔率大極(ji)板薄，有利于電解(jie)液(ye)的(de)擴散(san)，極(ji)化的(de)作(zuo)用就會減小。
極板上電(dian)(dian)流的帆布均勻(yun)，電(dian)(dian)阻小，可以減少充電(dian)(dian)電(dian)(dian)流的損耗。
放電(dian)深(shen)度。放電(dian)深(shen)度越深(shen)，正極活性物(wu)質和風(feng)機活性物(wu)質都會減少，需要通過充電(dian)轉化(hua)的物(wu)質會增(zeng)多，這(zhe)樣可以提高充電(dian)的接受能力。
