充電器:是一種通(tong)過向充電池通(tong)入(ru)電流而為電池充入(ru)能量的裝置(zhi)。是一種將交流電轉換為低壓直流電的設(she)備。

脈沖式充電器:一種對可充(chong)(chong)電(dian)電(dian)池按(an)照脈沖方(fang)式(shi)(shi)進行充(chong)(chong)電(dian)的電(dian)器裝置.它是按(an)照充(chong)(chong)電(dian)方(fang)式(shi)(shi)來(lai)區別的,有(you)別于(yu)其它的充(chong)(chong)電(dian)方(fang)式(shi)(shi),例(li)如.手(shou)搖方(fang)式(shi)(shi)充(chong)(chong)電(dian)器,恒壓(ya)充(chong)(chong)電(dian)器以及(ji)混(hun)合方(fang)法的三段(duan)式(shi)(shi)充(chong)(chong)電(dian)器(第一個階(jie)(jie)(jie)段(duan)叫充(chong)(chong)電(dian)限流(liu)階(jie)(jie)(jie)段(duan)，第二個階(jie)(jie)(jie)段(duan)叫高恒壓(ya)階(jie)(jie)(jie)段(duan)，第三個階(jie)(jie)(jie)段(duan)叫小電(dian)流(liu)低恒壓(ya)階(jie)(jie)(jie)段(duan)).

　　1967年美國人麥斯研(yan)究公布.用大于(yu)1C(C是電(dian)(dian)(dian)(dian)池(chi)容量(liang))率脈沖(chong)電(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)，充電(dian)(dian)(dian)(dian)間歇時對電(dian)(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)(dian)。放電(dian)(dian)(dian)(dian)有利于(yu)消除極(ji)化(hua)、降低電(dian)(dian)(dian)(dian)解液溫(wen)度(du)、提高(gao)極(ji)板(ban)接受電(dian)(dian)(dian)(dian)荷(he)的(de)能力。可以(yi)在加速電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)過(guo)程同時保證獲得足量(liang)的(de)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)能.
