鋰電(dian)(dian)池的(de)充(chong)(chong)電(dian)(dian)方(fang)法為適應當前市場(chang)需求正在向(xiang)著快(kuai)充(chong)(chong)技術方(fang)向(xiang)發展，就目(mu)前市場(chang)上電(dian)(dian)池快(kuai)充(chong)(chong)技術來(lai)(lai)說主要有括脈沖充(chong)(chong)電(dian)(dian)、Reflex充(chong)(chong)電(dian)(dian)，智能充(chong)(chong)電(dian)(dian)和間歇充(chong)(chong)電(dian)(dian)法這四(si)種，不同(tong)的(de)電(dian)(dian)池品(pin)牌，其適合的(de)充(chong)(chong)電(dian)(dian)方(fang)式(shi)也(ye)有所不同(tong)。下邊(bian)我們一起來(lai)(lai)看看鋰離子電(dian)(dian)池的(de)四(si)種快(kuai)充(chong)(chong)充(chong)(chong)電(dian)(dian)方(fang)法吧。

1、鋰(li)電池快充方案：脈沖充電

這也是來自文獻中的一個脈沖充電方式，其脈沖過程布置在充電觸及上限電壓4.2V以后，并在4.2V以上持續進行。暫且不提其詳細參數設置的合理性，不同類型電芯存在差異。我們關注一(yi)下脈(mo)沖實施過程(cheng)。

脈(mo)沖充(chong)電(dian)曲線，主要包含三個階段(duan)：預(yu)充(chong)、恒(heng)流充(chong)電(dian)和脈(mo)沖充(chong)電(dian)。在恒(heng)流充(chong)電(dian)過程中(zhong)以恒(heng)定電(dian)流對電(dian)池(chi)進(jin)行充(chong)電(dian)，部分能量被(bei)轉移(yi)至鋰電(dian)池(chi)內部。

2、鋰電池快(kuai)(kuai)充(chong)方案：Reflex快(kuai)(kuai)速充(chong)電法(fa)

Reflex快速充(chong)電(dian)(dian)具體方(fang)法(fa)，也(ye)被稱作(zuo)反射(she)充(chong)電(dian)(dian)方(fang)法(fa)或“打嗝”充(chong)電(dian)(dian)方(fang)法(fa)。該方(fang)法(fa)的(de)每個工作(zuo)周期(qi)包(bao)括(kuo)正向充(chong)電(dian)(dian)、反向瞬間放電(dian)(dian)和停充(chong)3個階段(duan)。它在很大的(de)程度上解決了電(dian)(dian)池極化現象，推動了充(chong)電(dian)(dian)效率。可是反向放電(dian)(dian)會縮短鋰(li)電(dian)(dian)池壽命。

在每個充(chong)(chong)電(dian)(dian)周(zhou)期中，先采用2C的電(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)時(shi)(shi)間(jian)(jian)為(wei)10s的Tc，然后停(ting)充(chong)(chong)時(shi)(shi)間(jian)(jian)為(wei)0.5s的Tr1，反向放電(dian)(dian)時(shi)(shi)間(jian)(jian)為(wei)1s的Td，停(ting)充(chong)(chong)時(shi)(shi)間(jian)(jian)為(wei)0.5s的Tr2，每個充(chong)(chong)電(dian)(dian)循環時(shi)(shi)間(jian)(jian)為(wei)12s。隨著充(chong)(chong)電(dian)(dian)的進行，充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)會逐漸變小。

3、鋰(li)電(dian)池快充方案：智能(neng)充電(dian)法

智(zhi)能充(chong)電(dian)(dian)(dian)(dian)是現階段較先進的充(chong)電(dian)(dian)(dian)(dian)方(fang)法，打個(ge)比方(fang)說，其(qi)核心原理是應用du/dt和(he)di/dt控制技術，根據檢(jian)查電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)流的增量來判斷電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)狀態(tai)，實時跟蹤電(dian)(dian)(dian)(dian)池(chi)可接受的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，使充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流自(zi)始自(zi)終在電(dian)(dian)(dian)(dian)池(chi)可接受的最大(da)充(chong)電(dian)(dian)(dian)(dian)曲線附近。

4、鋰電池快充(chong)方案(an)：間(jian)歇充(chong)電法

鋰電(dian)(dian)(dian)(dian)池間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)包括變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)流間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)和(he)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)壓間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)。變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)流間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)，變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)流間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)是由廈(sha)大陳體(ti)銜專家教授(shou)所提出(chu)的，它的作用(yong)是將恒流充(chong)電(dian)(dian)(dian)(dian)改(gai)成(cheng)限壓變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)流間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)。變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)壓間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)，在變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)流間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)的前提下，有人又研(yan)究了(le)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)壓間歇(xie)(xie)充(chong)電(dian)(dian)(dian)(dian)法(fa)(fa)(fa)。兩者(zhe)的差異主(zhu)要在于第(di)一階段(duan)的充(chong)電(dian)(dian)(dian)(dian)過程。
