充電器:是一(yi)種通(tong)過向充(chong)電(dian)池(chi)通(tong)入(ru)電(dian)流(liu)而為電(dian)池(chi)充(chong)入(ru)能量的(de)裝(zhuang)置(zhi)。是一(yi)種將交流(liu)電(dian)轉換(huan)為低壓直流(liu)電(dian)的(de)設(she)備。

脈沖式充電器:一種對可充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池按照(zhao)脈沖方式(shi)(shi)進行充(chong)電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)器(qi)裝(zhuang)置.它是按照(zhao)充(chong)電(dian)(dian)(dian)方式(shi)(shi)來區別(bie)的(de)(de),有別(bie)于其它的(de)(de)充(chong)電(dian)(dian)(dian)方式(shi)(shi),例(li)如.手搖方式(shi)(shi)充(chong)電(dian)(dian)(dian)器(qi),恒壓充(chong)電(dian)(dian)(dian)器(qi)以及混合方法(fa)的(de)(de)三段(duan)(duan)式(shi)(shi)充(chong)電(dian)(dian)(dian)器(qi)(第(di)一個(ge)階(jie)段(duan)(duan)叫充(chong)電(dian)(dian)(dian)限(xian)流階(jie)段(duan)(duan)，第(di)二個(ge)階(jie)段(duan)(duan)叫高恒壓階(jie)段(duan)(duan)，第(di)三個(ge)階(jie)段(duan)(duan)叫小電(dian)(dian)(dian)流低恒壓階(jie)段(duan)(duan)).

　　1967年美(mei)國人麥斯(si)研究公布.用大(da)于1C(C是電池容量(liang))率脈沖電流充(chong)電，充(chong)電間歇時對電池放電。放電有利(li)于消除極化、降低電解液(ye)溫度、提高極板接受電荷的能力。可以(yi)在(zai)加速(su)電池充(chong)電過(guo)程同時保證(zheng)獲得足量(liang)的充(chong)電電能.
