由于高空作業平臺的(de)大規(gui)模(mo)應用，經(jing)常(chang)有客戶致電過來(lai)詢問高空作業平臺蓄電池(chi)怎么維護，下(xia)(xia)面泰州惠澤機(ji)械就蓄電池(chi)充電問題(ti)為您詳(xiang)細解說一下(xia)(xia)。

電(dian)(dian)(dian)池從電(dian)(dian)(dian)源供電(dian)(dian)(dian)系統中下線進(jin)行充(chong)(chong)電(dian)(dian)(dian)，可(ke)以在很短的時(shi)間內補充(chong)(chong)電(dian)(dian)(dian)池所需要的電(dian)(dian)(dian)能，這(zhe)種方法就叫做快速充(chong)(chong)電(dian)(dian)(dian)。

快速充(chong)(chong)(chong)電(dian)也采用限(xian)(xian)流(liu)恒(heng)(heng)壓(ya)(ya)式，充(chong)(chong)(chong)電(dian)可以在十二個(ge)小時(shi)之內(nei)完成，這(zhe)幾種(zhong)充(chong)(chong)(chong)電(dian)方法包含限(xian)(xian)流(liu)充(chong)(chong)(chong)電(dian)和恒(heng)(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)的兩個(ge)階段，如果只是恒(heng)(heng)壓(ya)(ya)不限(xian)(xian)流(liu)，對電(dian)池損壞會(hui)很大(da)(da)。因(yin)為(wei)(wei)恒(heng)(heng)壓(ya)(ya)充(chong)(chong)(chong)電(dian)初期充(chong)(chong)(chong)電(dian)電(dian)流(liu)會(hui)特(te)別大(da)(da)，過大(da)(da)的充(chong)(chong)(chong)電(dian)電(dian)流(liu)使電(dian)極上活性物質小孔(kong)中(zhong)電(dian)解(jie)(jie)液濃(nong)度升高，而電(dian)解(jie)(jie)液的擴散速度沒有濃(nong)差(cha)極化和電(dian)化學(xue)極化的綜合速度的要求(qiu)，會(hui)產生非(fei)常高的電(dian)位(wei)趨勢，這(zhe)時(shi)充(chong)(chong)(chong)電(dian)電(dian)壓(ya)(ya)值就(jiu)恒(heng)(heng)定(ding)了，就(jiu)會(hui)轉化為(wei)(wei)充(chong)(chong)(chong)電(dian)的電(dian)流(liu)。

在充(chong)電初期充(chong)電電流(liu)過大的(de)時候，正極活性物質會(hui)(hui)和(he)負極活性物質會(hui)(hui)有很細很密的(de)晶體微粒，會(hui)(hui)影響充(chong)電的(de)深度。另外在充(chong)電初期要實現大電流(liu)需要大功率(lv)充(chong)電設備，因(yin)此充(chong)電電流(liu)要限流(liu)。電流(liu)的(de)功率(lv)和(he)哪些因(yin)素有關(guan)呢？

電(dian)池正極上(shang)活性物質(zhi)的(de)厚度和孔率。如果活性物質(zhi)孔率大極板薄，有利于電(dian)解液的(de)擴散，極化(hua)的(de)作用(yong)就(jiu)會減小。

極板上電(dian)(dian)流的(de)分(fen)布均勻，電(dian)(dian)阻(zu)小，可以減少充電(dian)(dian)電(dian)(dian)流的(de)損耗。

放電(dian)(dian)深度(du)。放電(dian)(dian)深度(du)越深，正極(ji)活性物(wu)(wu)質(zhi)和風機活性物(wu)(wu)質(zhi)都會(hui)減少，需(xu)要通過充電(dian)(dian)轉化的物(wu)(wu)質(zhi)會(hui)增多，這(zhe)樣可以提(ti)高充電(dian)(dian)的接受能力。
