充電是使用充電電池的重要步驟。適當合理的充電對延長電池壽命很有好處，而野蠻胡亂充電將會對電池壽命有很大影響。鋰電池基本(ben)都(dou)是根據各個產品(pin)單(dan)獨封裝，互不(bu)通用(yong)的(de)(de)，因此各個產品(pin)也提供各自的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)設備，互不(bu)通用(yong)，在使(shi)用(yong)時(shi)只(zhi)要(yao)遵循(xun)各自的(de)(de)說明書使(shi)用(yong)即(ji)可。所以(yi)本(ben)篇(pian)對電(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)介(jie)紹主要(yao)是指鎳(nie)鎘電(dian)(dian)(dian)(dian)池和(he)鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)池。對鎳(nie)隔電(dian)(dian)(dian)(dian)池和(he)鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)有兩種方式(shi)，就是我(wo)們大家所熟知的(de)(de)“快(kuai)(kuai)(kuai)充(chong)(chong)”和(he)“慢(man)充(chong)(chong)”。快(kuai)(kuai)(kuai)充(chong)(chong)和(he)慢(man)充(chong)(chong)是充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)一(yi)個重要(yao)概念，只(zhi)有了解了快(kuai)(kuai)(kuai)充(chong)(chong)和(he)慢(man)充(chong)(chong)才(cai)能(neng)正確掌握充(chong)(chong)電(dian)(dian)(dian)(dian)。

　　首先，快充和慢充是個相對的概念。有人曾問，充電器充(chong)(chong)(chong)電電流(liu)有(you)200mA，是(shi)(shi)不是(shi)(shi)快充(chong)(chong)(chong)？這個答(da)案并不絕對，應該(gai)回答(da)對于某(mou)(mou)些(xie)電池來說(shuo)，它是(shi)(shi)快充(chong)(chong)(chong)，而對于某(mou)(mou)些(xie)電池來說(shuo)，它只是(shi)(shi)慢充(chong)(chong)(chong)。那(nei)我(wo)們(men)究竟怎樣來判(pan)別快充(chong)(chong)(chong)還(huan)是(shi)(shi)慢充(chong)(chong)(chong)呢(ni)？

　　例如(ru)一(yi)(yi)節5號(hao)鎳氫電(dian)(dian)池(chi)(chi)的電(dian)(dian)容(rong)量(liang)為(wei)1200mAH，而(er)另一(yi)(yi)節則為(wei)1600mAH。把一(yi)(yi)節電(dian)(dian)池(chi)(chi)的電(dian)(dian)容(rong)量(liang)稱為(wei)1C，可(ke)見1C只是一(yi)(yi)個(ge)邏(luo)輯(ji)概念，同樣的1C，并不相等(deng)。在充(chong)(chong)電(dian)(dian)時，充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)小于0.1C時，稱為(wei)涓流(liu)充(chong)(chong)電(dian)(dian)。顧名(ming)思義，是指電(dian)(dian)流(liu)很(hen)小。一(yi)(yi)般而(er)言，涓流(liu)充(chong)(chong)電(dian)(dian)能夠(gou)把電(dian)(dian)池(chi)(chi)充(chong)(chong)的很(hen)足，而(er)不傷害(hai)電(dian)(dian)池(chi)(chi)壽命，但(dan)用(yong)(yong)涓流(liu)充(chong)(chong)電(dian)(dian)所花的時間實在太長，因此很(hen)少單獨使(shi)用(yong)(yong)，而(er)是和(he)其(qi)它充(chong)(chong)電(dian)(dian)方式結合使(shi)用(yong)(yong)。

　　充電電流在0.1C-0.2C之間(jian)時(shi)，稱為慢速充電。充電電流大于(yu)(yu)(yu)0.2C，小于(yu)(yu)(yu)0.8C則是快速充電。而(er)當(dang)充電電流大于(yu)(yu)(yu)0.8C時(shi)，稱之為超高速充電。

　　正因(yin)為1C是個(ge)邏(luo)輯概念而非絕對值，因(yin)此根據1C折算的快(kuai)充(chong)慢充(chong)也是一個(ge)相(xiang)對值。前面例(li)子中提(ti)到的200mA充(chong)電電流對于(yu)1200mAH的電池來說(shuo)是慢充(chong)，而對于(yu)700mAH的電池來說(shuo)就是快(kuai)充(chong)
