充(chong)電機的現(xian)狀
    目前，礦用電(dian)(dian)(dian)機車蓄電(dian)(dian)(dian)池(chi)(chi)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)，無論是(shi)恒流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)、恒壓(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)或(huo)是(shi)先恒流(liu)(liu)再恒壓(ya)的(de)(de)分(fen)段式(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)，都有一個共(gong)同的(de)(de)問題，就是(shi)這(zhe)種(zhong)(zhong)小(xiao)電(dian)(dian)(dian)流(liu)(liu)慢充(chong)(chong)(chong)方式(shi)，蓄電(dian)(dian)(dian)池(chi)(chi)初充(chong)(chong)(chong)需(xu)70小(xiao)時(shi)以上(shang)，進行普通充(chong)(chong)(chong)電(dian)(dian)(dian)也需(xu)10小(xiao)時(shi)以上(shang)，這(zhe)種(zhong)(zhong)充(chong)(chong)(chong)電(dian)(dian)(dian)方式(shi)在充(chong)(chong)(chong)電(dian)(dian)(dian)過程(cheng)的(de)(de)初期，充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)遠(yuan)小(xiao)于蓄電(dian)(dian)(dian)池(chi)(chi)可接受(shou)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)，因而(er)拉長了(le)充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間，造(zao)成(cheng)電(dian)(dian)(dian)能的(de)(de)浪費。而(er)在充(chong)(chong)(chong)電(dian)(dian)(dian)過程(cheng)的(de)(de)后期，充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)又大于蓄電(dian)(dian)(dian)池(chi)(chi)可接受(shou)的(de)(de)電(dian)(dian)(dian)流(liu)(liu)，蓄電(dian)(dian)(dian)池(chi)(chi)內(nei)部(bu)溫度升高，產(chan)生大量析氣，并(bing)形成(cheng)內(nei)部(bu)硫(liu)化結晶，大大縮短了(le)蓄電(dian)(dian)(dian)池(chi)(chi)的(de)(de)循環使用壽命，甚至有可能永久性地(di)損壞電(dian)(dian)(dian)池(chi)(chi)。這(zhe)不僅造(zao)成(cheng)了(le)浪費，也增加了(le)對(dui)環境的(de)(de)污染(ran)。同時(shi)，這(zhe)種(zhong)(zhong)傳(chuan)統充(chong)(chong)(chong)電(dian)(dian)(dian)機采用變壓(ya)器變壓(ya)整流(liu)(liu)，可控硅控制的(de)(de)途徑，技術落后，設備笨重，可靠性也差。
