充電(dian)機(ji)的現狀
    目(mu)前，礦(kuang)用電(dian)(dian)(dian)(dian)(dian)(dian)機車蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，無(wu)論(lun)是(shi)(shi)恒(heng)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)、恒(heng)壓(ya)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)或是(shi)(shi)先恒(heng)流(liu)(liu)再恒(heng)壓(ya)的分段式充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，都有(you)(you)一個共同的問題，就是(shi)(shi)這(zhe)種小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)慢(man)充(chong)(chong)方式，蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)初充(chong)(chong)需70小(xiao)時以上，進行普通(tong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)也(ye)(ye)需10小(xiao)時以上，這(zhe)種充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方式在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)的初期，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)遠小(xiao)于蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可(ke)(ke)接(jie)受的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，因而拉長了充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時間，造成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)能的浪費(fei)。而在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)的后期，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)又大于蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可(ke)(ke)接(jie)受的電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內部溫度升(sheng)高，產(chan)生大量析氣(qi)，并形成(cheng)內部硫化結晶(jing)，大大縮短(duan)了蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的循環(huan)使用壽(shou)命，甚至有(you)(you)可(ke)(ke)能永久(jiu)性(xing)(xing)地(di)損壞電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。這(zhe)不僅造成(cheng)了浪費(fei)，也(ye)(ye)增加了對環(huan)境的污染。同時，這(zhe)種傳統充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機采用變(bian)壓(ya)器變(bian)壓(ya)整流(liu)(liu)，可(ke)(ke)控(kong)硅控(kong)制的途徑，技術落(luo)后，設(she)備笨重，可(ke)(ke)靠性(xing)(xing)也(ye)(ye)差。
