1、利用鋰離子電池組內(nei)部均(jun)衡(heng)保護板的均(jun)衡(heng)功能(neng)

此時(shi)直接利(li)用(yong)均衡保護板已經不行，因(yin)為充(chong)電(dian)轉綠燈后電(dian)流為0，繼續(xu)充(chong)電(dian)毫(hao)無用(yong)途(tu)。

要(yao)簡單改造一下充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器，在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)線上串聯一個(ge)電(dian)(dian)(dian)(dian)(dian)阻，這(zhe)個(ge)電(dian)(dian)(dian)(dian)(dian)阻的(de)阻值要(yao)與內部均(jun)衡(heng)板(ban)的(de)均(jun)衡(heng)電(dian)(dian)(dian)(dian)(dian)阻相同(tong)，例如關(guan)于(yu)T260就(jiu)串聯220歐，假如是GW14就(jiu)串聯100歐，功(gong)率2W-5W，這(zhe)樣(yang)再(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)就(jiu)比較小(xiao)，小(xiao)于(yu)均(jun)衡(heng)電(dian)(dian)(dian)(dian)(dian)流(liu)，這(zhe)樣(yang)其MOS管(guan)道通后(hou)就(jiu)可以(yi)完全分流(liu)，就(jiu)不(bu)會觸(chu)發過壓保護(hu)。而這(zhe)較小(xiao)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)，就(jiu)可以(yi)電(dian)(dian)(dian)(dian)(dian)池組中電(dian)(dian)(dian)(dian)(dian)壓低的(de)電(dian)(dian)(dian)(dian)(dian)池進(jin)行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，只要(yao)時間(jian)(jian)足夠(gou)長，就(jiu)可以(yi)達到均(jun)衡(heng)。至(zhi)于(yu)到底充(chong)(chong)多長時間(jian)(jian)，取決于(yu)失衡(heng)程(cheng)度(du)。假設不(bu)均(jun)衡(heng)程(cheng)度(du)為50%，即某個(ge)電(dian)(dian)(dian)(dian)(dian)池只有(you)(you)半電(dian)(dian)(dian)(dian)(dian)，那(nei)至(zhi)少要(yao)再(zai)充(chong)(chong)入1300mAh，80mA的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)就(jiu)要(yao)16小(xiao)時。關(guan)于(yu)IPST260，均(jun)衡(heng)電(dian)(dian)(dian)(dian)(dian)流(liu)只有(you)(you)20mA，因此要(yao)采用221的(de)電(dian)(dian)(dian)(dian)(dian)阻（220歐），充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)(jian)為1300/20=65小(xiao)時。

使(shi)用此法，先把獨輪車按照(zhao)常(chang)規的方法充電(dian)充滿，然后串入電(dian)阻進行(xing)均衡充。改正不均衡后，去(qu)掉(diao)電(dian)阻，用膠布把電(dian)纜包好。

2、最(zui)徹底的還是鋰離子電(dian)池組內部手動均衡辦法

鋰離子電池組充滿后，拆開電池倉，逐個測量電芯電壓(ya)(ya)，關于電壓(ya)(ya)低(di)的，用(yong)單(dan)節鋰電充(chong)(chong)電器，引(yin)出兩(liang)根(gen)線，把虧電電芯(xin)吃小灶充(chong)(chong)滿；假如某節電壓(ya)(ya)過高可以單(dan)獨用(yong)電阻放電。

3、制作均衡(heng)(heng)器，適合小批量快速均衡(heng)(heng)用

制作一(yi)個電(dian)路板，內帶(dai)功率(lv)均衡器件，具(ju)有充電(dian)器插座、兩個電(dian)池插頭。

利用原來的充電器作為電源輸入(ru)，而(er)輸出部分就是與(yu)獨輪車內部電壓檢測插座(zuo)相同(tong)的兩個(ge)插頭（9P和11P）。

均衡(heng)(heng)器內部(bu)包含16個串聯的(de)(de)4.18V限壓穩定器，接到T260的(de)(de)電(dian)池檢測口的(de)(de)19根(gen)線上，實現外部(bu)均衡(heng)(heng)充電(dian)。

做16個4.185V的(de)超級穩壓管(guan)，先(xian)把獨(du)輪車(che)充滿，開(kai)蓋、拔下各電源線(xian)，把均衡(heng)板插(cha)到電池的(de)檢(jian)測(ce)口上，再把充電器接到均衡(heng)板上，充電即可：

超級穩壓(ya)管的用(yong)途，就(jiu)是在(zai)每節(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)達(da)到(dao)4.185V之前，不(bu)(bu)起任(ren)何用(yong)途，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)照常充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，但任(ren)何一(yi)(yi)節(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)達(da)到(dao)4.185V的時候(hou)對應穩壓(ya)管就(jiu)導(dao)通開(kai)始分流(liu)，旁(pang)路了(le)(le)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)使(shi)得該電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)(bu)會增(zeng)大(da)，即電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)保(bao)持在(zai)4.185V，因此(ci)也就(jiu)不(bu)(bu)過(guo)充(chong)，但此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)繼(ji)續(xu)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)低的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。待所有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)都達(da)到(dao)4.185V后，保(bao)持一(yi)(yi)段(duan)時，各鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)就(jiu)均衡了(le)(le)。
