充電機的現狀
    目(mu)前，礦用電(dian)(dian)(dian)機車蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的充(chong)電(dian)(dian)(dian)，無論是(shi)(shi)恒(heng)流(liu)充(chong)電(dian)(dian)(dian)、恒(heng)壓(ya)充(chong)電(dian)(dian)(dian)或是(shi)(shi)先恒(heng)流(liu)再恒(heng)壓(ya)的分段式(shi)充(chong)電(dian)(dian)(dian)，都有一(yi)個共同的問題，就(jiu)是(shi)(shi)這(zhe)種(zhong)小(xiao)(xiao)(xiao)電(dian)(dian)(dian)流(liu)慢充(chong)方(fang)式(shi)，蓄(xu)電(dian)(dian)(dian)池(chi)(chi)初(chu)(chu)充(chong)需70小(xiao)(xiao)(xiao)時以上，進行普通充(chong)電(dian)(dian)(dian)也需10小(xiao)(xiao)(xiao)時以上，這(zhe)種(zhong)充(chong)電(dian)(dian)(dian)方(fang)式(shi)在(zai)充(chong)電(dian)(dian)(dian)過(guo)程(cheng)(cheng)的初(chu)(chu)期，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)遠小(xiao)(xiao)(xiao)于(yu)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)可接(jie)受的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)，因而拉長了(le)(le)充(chong)電(dian)(dian)(dian)時間，造(zao)成電(dian)(dian)(dian)能的浪費(fei)(fei)。而在(zai)充(chong)電(dian)(dian)(dian)過(guo)程(cheng)(cheng)的后(hou)期，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)又(you)大(da)于(yu)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)可接(jie)受的電(dian)(dian)(dian)流(liu)，蓄(xu)電(dian)(dian)(dian)池(chi)(chi)內部(bu)(bu)溫度升高，產生大(da)量析氣，并形成內部(bu)(bu)硫化結晶(jing)，大(da)大(da)縮短(duan)了(le)(le)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的循(xun)環使用壽命，甚至有可能永久性(xing)地(di)損(sun)壞電(dian)(dian)(dian)池(chi)(chi)。這(zhe)不僅造(zao)成了(le)(le)浪費(fei)(fei)，也增(zeng)加了(le)(le)對環境的污(wu)染。同時，這(zhe)種(zhong)傳統充(chong)電(dian)(dian)(dian)機采用變(bian)壓(ya)器變(bian)壓(ya)整流(liu)，可控硅(gui)控制的途徑(jing)，技術落(luo)后(hou)，設(she)備笨重，可靠性(xing)也差。
