充電電池用完電后都需要進行充電來繼續使用，使用的時候經常會聽到電池廠家說的(de)關(guan)于充(chong)(chong)電(dian)(dian)方面的(de)知識(shi)，其中就有(you)關(guan)于涓流充(chong)(chong)電(dian)(dian)的(de)相(xiang)關(guan)知識(shi)，但是什么是涓流充(chong)(chong)電(dian)(dian)呢(ni)，下面來簡單介紹一(yi)下吧。

涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)是(shi)指電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)滿(man)后進行(xing)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)，能(neng)讓電(dian)(dian)(dian)(dian)(dian)子(zi)保持(chi)流(liu)(liu)動(dong)，延長電(dian)(dian)(dian)(dian)(dian)子(zi)使用壽命(ming)。手機電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)全過程(cheng)包(bao)括快速充(chong)電(dian)(dian)(dian)(dian)(dian)、持(chi)續式充(chong)電(dian)(dian)(dian)(dian)(dian)、涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)三個階(jie)段。涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)即指電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)滿(man)后的(de)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)，可(ke)以保護電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽命(ming)。

快速充(chong)電(dian)(dian)：能夠迅速地將電(dian)(dian)池(chi)充(chong)到100%，但仍需(xu)進(jin)行持續式充(chong)電(dian)(dian)才能完全充(chong)滿(man)；持續式充(chong)電(dian)(dian)：在電(dian)(dian)池(chi)即將充(chong)滿(man)的狀態(tai)下，充(chong)電(dian)(dian)電(dian)(dian)流(liu)逐(zhu)漸減小，確保電(dian)(dian)池(chi)完全充(chong)滿(man)；洞流(liu)充(chong)電(dian)(dian)：電(dian)(dian)池(chi)充(chong)滿(man)后(hou)進(jin)行小電(dian)(dian)流(liu)充(chong)電(dian)(dian)，能讓電(dian)(dian)子(zi)保持流(liu)動(dong)，延長電(dian)(dian)子(zi)使用壽命。

涓(juan)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)是(shi)用(yong)來彌補電(dian)(dian)(dian)(dian)(dian)池在充(chong)滿電(dian)(dian)(dian)(dian)(dian)后由(you)于自放電(dian)(dian)(dian)(dian)(dian)而造成的(de)容量(liang)損(sun)(sun)失(shi)(shi)。一般采用(yong)脈沖電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)來實現上述(shu)目的(de)。根(gen)據(ju)以往(wang)測(ce)試的(de)相關(guan)經(jing)驗(yan)，電(dian)(dian)(dian)(dian)(dian)池在充(chong)滿電(dian)(dian)(dian)(dian)(dian)后由(you)于自放電(dian)(dian)(dian)(dian)(dian)損(sun)(sun)失(shi)(shi)的(de)容量(liang)大(da)約是(shi)標(biao)稱容量(liang)的(de)5%。從(cong)理論上講，以C/500的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)持續充(chong)電(dian)(dian)(dian)(dian)(dian)即(ji)(ji)可(ke)彌補自放電(dian)(dian)(dian)(dian)(dian)造成的(de)容量(liang)損(sun)(sun)失(shi)(shi)。總的(de)來說，充(chong)電(dian)(dian)(dian)(dian)(dian)應(ying)用(yong)里(li)所稱的(de)洞(dong)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)對手機(ji)電(dian)(dian)(dian)(dian)(dian)量(liang)有(you)所幫(bang)助，但事實并非如(ru)此(ci)，如(ru)今智能(neng)手機(ji)電(dian)(dian)(dian)(dian)(dian)池不(bu)耐用(yong)已經(jing)是(shi)通病，即(ji)(ji)便電(dian)(dian)(dian)(dian)(dian)池充(chong)滿到99%，還能(neng)有(you)1%作為損(sun)(sun)失(shi)(shi)容量(liang)，實際使用(yong)影響基(ji)本不(bu)大(da)，因此(ci)小(xiao)編認(ren)為涓(juan)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)其實是(shi)沒有(you)必要的(de)。
