充電器:是一種(zhong)通過向充(chong)(chong)電池通入電流而(er)為(wei)電池充(chong)(chong)入能量的裝置。是一種(zhong)將交流電轉換為(wei)低壓直流電的設備。

脈沖式充電器:一種對(dui)可充電(dian)(dian)電(dian)(dian)池按(an)照脈(mo)沖方式(shi)進行充電(dian)(dian)的(de)電(dian)(dian)器(qi)(qi)裝置(zhi).它(ta)是按(an)照充電(dian)(dian)方式(shi)來區別(bie)的(de),有別(bie)于其它(ta)的(de)充電(dian)(dian)方式(shi),例(li)如.手搖方式(shi)充電(dian)(dian)器(qi)(qi),恒壓充電(dian)(dian)器(qi)(qi)以及混合方法的(de)三段(duan)式(shi)充電(dian)(dian)器(qi)(qi)(第一個(ge)階段(duan)叫充電(dian)(dian)限流階段(duan)，第二個(ge)階段(duan)叫高(gao)恒壓階段(duan)，第三個(ge)階段(duan)叫小電(dian)(dian)流低(di)恒壓階段(duan)).

　　1967年美國(guo)人麥斯研(yan)究公布.用(yong)大于(yu)1C(C是電(dian)(dian)(dian)(dian)池(chi)容量(liang)(liang))率脈沖電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)間歇(xie)時(shi)(shi)對電(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)。放(fang)電(dian)(dian)(dian)(dian)有利于(yu)消除極(ji)化(hua)、降低(di)電(dian)(dian)(dian)(dian)解液溫度、提高(gao)極(ji)板接受電(dian)(dian)(dian)(dian)荷(he)的(de)(de)能力。可以在(zai)加速電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)過(guo)程同時(shi)(shi)保證獲得足量(liang)(liang)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)能.
