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)都是根據各個產品(pin)單(dan)獨封裝(zhuang)，互(hu)不通(tong)用的，因(yin)此各個產品(pin)也提供各自的充(chong)(chong)電(dian)(dian)設備(bei)，互(hu)不通(tong)用，在使(shi)用時只(zhi)要(yao)遵循各自的說(shuo)明(ming)書使(shi)用即(ji)可。所以本(ben)篇對電(dian)(dian)池充(chong)(chong)電(dian)(dian)的介紹主要(yao)是指鎳鎘電(dian)(dian)池和鎳氫電(dian)(dian)池。對鎳隔電(dian)(dian)池和鎳氫電(dian)(dian)池充(chong)(chong)電(dian)(dian)有(you)兩種方(fang)式，就是我們大家所熟知的“快充(chong)(chong)”和“慢(man)充(chong)(chong)”。快充(chong)(chong)和慢(man)充(chong)(chong)是充(chong)(chong)電(dian)(dian)的一個重(zhong)要(yao)概念，只(zhi)有(you)了(le)解(jie)了(le)快充(chong)(chong)和慢(man)充(chong)(chong)才能正確掌握充(chong)(chong)電(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)電(dian)電(dian)流有200mA，是(shi)不是(shi)快充(chong)？這個答案并不絕對，應(ying)該回答對于(yu)某些電(dian)池來(lai)說(shuo)，它是(shi)快充(chong)，而對于(yu)某些電(dian)池來(lai)說(shuo)，它只是(shi)慢(man)充(chong)。那(nei)我們究竟怎樣來(lai)判別(bie)快充(chong)還是(shi)慢(man)充(chong)呢？

　　例如一(yi)節(jie)(jie)5號鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)容量為(wei)1200mAH，而另一(yi)節(jie)(jie)則為(wei)1600mAH。把一(yi)節(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)容量稱(cheng)為(wei)1C，可見1C只是一(yi)個邏輯概(gai)念(nian)，同樣的1C，并不相等。在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)小于0.1C時，稱(cheng)為(wei)涓流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。顧名思義，是指電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)很小。一(yi)般而言，涓流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)能夠把電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)的很足，而不傷害電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)壽命，但用涓流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)所花的時間實在(zai)太長(chang)，因此很少單獨使用，而是和其它充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方式結合(he)使用。

　　充(chong)電(dian)電(dian)流(liu)在0.1C-0.2C之間時，稱為慢速充(chong)電(dian)。充(chong)電(dian)電(dian)流(liu)大于0.2C，小(xiao)于0.8C則是快速充(chong)電(dian)。而(er)當充(chong)電(dian)電(dian)流(liu)大于0.8C時，稱之為超高速充(chong)電(dian)。

　　正(zheng)因為1C是個(ge)邏(luo)輯概念而(er)非絕對(dui)值，因此根據1C折(zhe)算的快(kuai)充(chong)(chong)慢充(chong)(chong)也是一個(ge)相(xiang)對(dui)值。前面例子中提(ti)到(dao)的200mA充(chong)(chong)電(dian)(dian)電(dian)(dian)流對(dui)于(yu)1200mAH的電(dian)(dian)池來說是慢充(chong)(chong)，而(er)對(dui)于(yu)700mAH的電(dian)(dian)池來說就是快(kuai)充(chong)(chong)
