充(chong)電(dian)(dian)(dian)(dian)是(shi)(shi)使(shi)用充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池的重要步驟(zou)。適當合理的充(chong)電(dian)(dian)(dian)(dian)對(dui)延長電(dian)(dian)(dian)(dian)池壽(shou)命很有(you)好處，而野蠻胡亂充(chong)電(dian)(dian)(dian)(dian)將會對(dui)電(dian)(dian)(dian)(dian)池壽(shou)命有(you)很大(da)影響。鋰電(dian)(dian)(dian)(dian)池基本(ben)都(dou)是(shi)(shi)根據各個(ge)(ge)產品(pin)單獨(du)封裝(zhuang)，互(hu)不通(tong)(tong)用的，因此(ci)各個(ge)(ge)產品(pin)也提供各自的充(chong)電(dian)(dian)(dian)(dian)設備，互(hu)不通(tong)(tong)用，在使(shi)用時只要遵(zun)循各自的說明書使(shi)用即可。所(suo)以本(ben)篇對(dui)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的介紹(shao)主要是(shi)(shi)指鎳(nie)鎘電(dian)(dian)(dian)(dian)池和鎳(nie)氫電(dian)(dian)(dian)(dian)池。 對(dui)鎳(nie)隔電(dian)(dian)(dian)(dian)池和鎳(nie)氫電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)有(you)兩種(zhong)方式(shi)，就是(shi)(shi)我們大(da)家所(suo)熟知的“快(kuai)充(chong)”和“慢充(chong)”。快(kuai)充(chong)和慢充(chong)是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)的一(yi)個(ge)(ge)重要概念，只有(you)了解(jie)了快(kuai)充(chong)和慢充(chong)才(cai)能正確掌握充(chong)電(dian)(dian)(dian)(dian)。
首先，快充(chong)和慢充(chong)是(shi)個相對的概念。有人曾問，充(chong)電(dian)(dian)(dian)器充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流有200mA，是(shi)不是(shi)快充(chong)？這個答(da)案并不一定，應(ying)該(gai)回答(da)對于某些(xie)電(dian)(dian)(dian)池來說，它是(shi)快充(chong)，而對于某些(xie)電(dian)(dian)(dian)池來說，它只是(shi)慢充(chong)。那我們究竟怎樣來判別快充(chong)還是(shi)慢充(chong)呢？
例如一(yi)節5號(hao)鎳氫電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)容(rong)量(liang)為(wei)(wei)(wei)1200mAH，而另一(yi)節則為(wei)(wei)(wei)1600mAH。把一(yi)節電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)容(rong)量(liang)稱(cheng)(cheng)為(wei)(wei)(wei)1C，可見1C只是(shi)(shi)一(yi)個邏輯(ji)概(gai)念，同樣的(de)1C，并不相等。在(zai)充(chong)電(dian)(dian)(dian)(dian)時，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)小(xiao)于0.1C時，稱(cheng)(cheng)為(wei)(wei)(wei)涓流(liu)充(chong)電(dian)(dian)(dian)(dian)。顧(gu)名思義(yi)，是(shi)(shi)指(zhi)電(dian)(dian)(dian)(dian)流(liu)很小(xiao)。一(yi)般而言(yan)，涓流(liu)充(chong)電(dian)(dian)(dian)(dian)能夠把電(dian)(dian)(dian)(dian)池充(chong)的(de)很足(zu)，而不傷害電(dian)(dian)(dian)(dian)池壽命(ming)，但(dan)用(yong)涓流(liu)充(chong)電(dian)(dian)(dian)(dian)所花的(de)時間(jian)實在(zai)太長，因此很少單獨使用(yong)，而是(shi)(shi)和其它充(chong)電(dian)(dian)(dian)(dian)方式結(jie)合使用(yong)。
充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)在0.1C-0.2C之間時，稱為慢速充(chong)(chong)電(dian)(dian)。充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)大于(yu)0.2C，小于(yu)0.8C則是快速充(chong)(chong)電(dian)(dian)。而(er)當(dang)充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)大于(yu)0.8C時，稱之為高(gao)速充(chong)(chong)電(dian)(dian)。
正(zheng)因為1C是(shi)個(ge)邏輯(ji)概念而非定值，因此根(gen)據1C折算的(de)快(kuai)充(chong)慢充(chong)也是(shi)一個(ge)相對值。前(qian)面例子中提到(dao)的(de)200mA充(chong)電電流對于(yu)1200mAH的(de)電池(chi)來(lai)(lai)說是(shi)慢充(chong)，而對于(yu)700mAH的(de)電池(chi)來(lai)(lai)說就是(shi)快(kuai)充(chong)。
