充電器:是(shi)一(yi)種通過向充電池(chi)通入電流(liu)而為電池(chi)充入能量的裝(zhuang)置。是(shi)一(yi)種將交流(liu)電轉換為低(di)壓直流(liu)電的設(she)備。

脈沖式充電器:一(yi)(yi)種對可充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池按照(zhao)脈沖方(fang)(fang)(fang)式(shi)進行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)器(qi)(qi)裝置(zhi).它是按照(zhao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方(fang)(fang)(fang)式(shi)來區(qu)別的,有別于(yu)其它的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方(fang)(fang)(fang)式(shi),例如.手搖方(fang)(fang)(fang)式(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi),恒壓充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)以及混合方(fang)(fang)(fang)法的三(san)段(duan)式(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(第一(yi)(yi)個階(jie)(jie)段(duan)叫(jiao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)限流(liu)階(jie)(jie)段(duan)，第二個階(jie)(jie)段(duan)叫(jiao)高恒壓階(jie)(jie)段(duan)，第三(san)個階(jie)(jie)段(duan)叫(jiao)小電(dian)(dian)(dian)(dian)流(liu)低恒壓階(jie)(jie)段(duan)).

　　1967年美國人麥(mai)斯(si)研究(jiu)公布.用(yong)大于(yu)1C(C是電(dian)(dian)(dian)(dian)池(chi)容量(liang))率脈(mo)沖電(dian)(dian)(dian)(dian)流(liu)充(chong)電(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)間歇時對電(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)。放(fang)電(dian)(dian)(dian)(dian)有(you)利于(yu)消(xiao)除極化、降低電(dian)(dian)(dian)(dian)解液溫度、提高極板接受電(dian)(dian)(dian)(dian)荷的能力。可以在加速(su)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)過程(cheng)同(tong)時保(bao)證獲得足量(liang)的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)能.
