充電器:是一種通(tong)過向充(chong)電(dian)(dian)池(chi)通(tong)入(ru)電(dian)(dian)流(liu)而為電(dian)(dian)池(chi)充(chong)入(ru)能量的裝置(zhi)。是一種將交流(liu)電(dian)(dian)轉(zhuan)換為低壓直流(liu)電(dian)(dian)的設備。

脈沖式充電器:一種對可充電(dian)電(dian)池按照脈沖方式(shi)(shi)進行(xing)充電(dian)的電(dian)器(qi)裝置.它是按照充電(dian)方式(shi)(shi)來區別的,有(you)別于(yu)其(qi)它的充電(dian)方式(shi)(shi),例如(ru).手(shou)搖方式(shi)(shi)充電(dian)器(qi),恒壓充電(dian)器(qi)以及(ji)混合(he)方法的三(san)段(duan)(duan)(duan)式(shi)(shi)充電(dian)器(qi)(第一個(ge)階段(duan)(duan)(duan)叫(jiao)充電(dian)限(xian)流(liu)階段(duan)(duan)(duan)，第二個(ge)階段(duan)(duan)(duan)叫(jiao)高恒壓階段(duan)(duan)(duan)，第三(san)個(ge)階段(duan)(duan)(duan)叫(jiao)小電(dian)流(liu)低(di)恒壓階段(duan)(duan)(duan)).

　　1967年美國人麥斯研究公(gong)布.用(yong)大于1C(C是電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量)率脈沖電(dian)(dian)(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)(dian)(dian)，充電(dian)(dian)(dian)(dian)(dian)間(jian)歇時對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)(dian)(dian)。放電(dian)(dian)(dian)(dian)(dian)有(you)利于消除(chu)極(ji)化(hua)、降低(di)電(dian)(dian)(dian)(dian)(dian)解液溫(wen)度、提高極(ji)板接受電(dian)(dian)(dian)(dian)(dian)荷(he)的能(neng)力。可以在加(jia)速電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)過程同時保證(zheng)獲得(de)足量的充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)能(neng).
