鉛(qian)酸蓄電(dian)池充電(dian)器(qi)參數(shu)解讀

電動車鉛酸蓄電池組充電時，有幾個關鍵參數：最高充電電壓、浮充電壓、浮充轉換電流、最大充電電流。它們應該是多少？如何制定？其中最主要的是最高充電電壓，多少為好？與析氣量、充入電容量和環境溫度又是什么關系？對此眾說不一，各電池生產廠家的(de)要求也不一樣。最(zui)高充(chong)(chong)電(dian)(dian)電(dian)(dian)壓值相對誤差范圍是(shi)多少？我們(men)不能脫(tuo)離實際的(de)工作(zuo)對象，盲目制定(ding)出超常(chang)規(gui)的(de)精度要求。我們(men)接(jie)到某(mou)電(dian)(dian)動車(che)售(shou)后服務部通(tong)知(zhi)：充(chong)(chong)電(dian)(dian)器比(bi)規(gui)定(ding)電(dian)(dian)壓高0.1V，電(dian)(dian)池因此(ci)熱失控(kong)而(er)充(chong)(chong)脹了；也接(jie)到通(tong)知(zhi)說：電(dian)(dian)壓比(bi)規(gui)定(ding)定(ding)低0.1V，電(dian)(dian)池欠充(chong)(chong)，提前(qian)報廢。一個千分之幾的(de)誤差造成如此(ci)嚴重后果(guo)，真是(shi)失之毫厘，謬之千里之外，鉛酸蓄(xu)電(dian)(dian)池果(guo)真有這么神(shen)秘嗎？為了解開困擾電(dian)(dian)動車(che)充(chong)(chong)電(dian)(dian)中(zhong)的(de)這個謎團，做(zuo)如下(xia)實驗。

用一(yi)個水槽盛滿水，電池(chi)放(fang)在水中(zhong)，在電池(chi)上方有一(yi)個收集氣體(ti)用的倒(dao)扣的漏斗(dou)，漏斗(dou)頂端(duan)裝(zhuang)有可以計量(liang)氣體(ti)容(rong)量(liang)的注射針筒。充電用可調穩壓電源，用兩只四位半數字萬(wan)用表測量(liang)充電電流和充電電壓。

試驗時(shi)間是在(zai)冬季，水溫5℃。實驗條件(jian)是統一(yi)用(yong)(yong)2A電(dian)(dian)流充(chong)電(dian)(dian)，最(zui)充(chong)電(dian)(dian)電(dian)(dian)壓(ya)分別用(yong)(yong)43V、44V、45V輪循環依次(ci)進行，浮充(chong)轉換電(dian)(dian)流一(yi)律(lv)400mA，記錄(lu)下(xia)每次(ci)的(de)(de)充(chong)電(dian)(dian)時(shi)間，包(bao)括充(chong)電(dian)(dian)末期(qi)隨時(shi)間電(dian)(dian)流下(xia)降各點數據(ju)、開(kai)始析氣(qi)電(dian)(dian)壓(ya)，按時(shi)間記錄(lu)析氣(qi)量。電(dian)(dian)池充(chong)完后(hou)，用(yong)(yong)萬(wan)分之幾精(jing)度的(de)(de)電(dian)(dian)量臺記錄(lu)放電(dian)(dian)容量。充(chong)入電(dian)(dian)量是在(zai)計算紙上讀(du)出時(shi)間電(dian)(dian)流曲線與坐標(biao)之間的(de)(de)面積（電(dian)(dian)容量就是充(chong)電(dian)(dian)電(dian)(dian)流對時(shi)間的(de)(de)定(ding)積分）。

備注：該電池組30℃時，放電容量為(wei)10Ah。

得到(dao)試驗(yan)數(shu)據后(hou)，最感(gan)到(dao)驚異的(de)(de)(de)(de)是(shi)(shi)：充(chong)(chong)(chong)入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量的(de)(de)(de)(de)多少幾(ji)乎與(yu)(yu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)無(wu)關。很多人認為充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)低(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)會充(chong)(chong)(chong)不滿，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)會提前鹽化(hua)報廢，特別(bie)是(shi)(shi)在(zai)冬季(ji)氣溫較低(di)的(de)(de)(de)(de)時候。而這次試驗(yan)正(zheng)好是(shi)(shi)在(zai)冬季(ji)，水溫只有5℃，試驗(yan)的(de)(de)(de)(de)中心電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)值是(shi)(shi)44V，上下偏差(cha)1V，相對誤(wu)差(cha)是(shi)(shi)2.3%。在(zai)用43V和45V充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)情(qing)況下，充(chong)(chong)(chong)入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量和放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量相差(cha)無(wu)幾(ji)，與(yu)(yu)大家公認的(de)(de)(de)(de)看法大相徑庭(ting)，試驗(yan)是(shi)(shi)用的(de)(de)(de)(de)同一組電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，同樣的(de)(de)(de)(de)充(chong)(chong)(chong)、放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)條件(jian)，輪番做同樣的(de)(de)(de)(de)測試，實驗(yan)數(shu)據重復同樣的(de)(de)(de)(de)規律，可排(pai)除偶(ou)然因(yin)素干擾，試驗(yan)數(shu)據是(shi)(shi)準(zhun)確(que)可信的(de)(de)(de)(de)。從(cong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)原理上看，只要(yao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)高(gao)(gao)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，都會給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一直到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)中的(de)(de)(de)(de)活性(xing)物質(zhi)轉(zhuan)換完成(cheng)。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)最高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，也就(jiu)是(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)始(shi)由(you)恒流區轉(zhuan)變到(dao)恒壓(ya)(ya)(ya)區，這種轉(zhuan)變是(shi)(shi)由(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)自身充(chong)(chong)(chong)入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量多少、活性(xing)物質(zhi)反應(ying)(ying)了多少決定的(de)(de)(de)(de)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)(de)(de)高(gao)(gao)低(di)，僅是(shi)(shi)能進行電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學(xue)反應(ying)(ying)的(de)(de)(de)(de)條件(jian)，只要(yao)高(gao)(gao)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)開(kai)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)就(jiu)會給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，多少物質(zhi)能參(can)與(yu)(yu)反應(ying)(ying)由(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)自身決定。從(cong)這個思路理解，就(jiu)不難得出(chu)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)高(gao)(gao)低(di)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量沒有多大影響(xiang)。

電池在(zai)42.5V～43.5V時(shi)開始析氣，而(er)析氣的速(su)度與(yu)充(chong)電電壓(ya)有(you)關。到充(chong)電結(jie)束時(shi)，總析氣量(liang)與(yu)充(chong)電最高電壓(ya)有(you)關，43V與(yu)45V總析氣量(liang)相差(cha)10位（注：以單格允許(xu)極限失水(shui)10克，18格相當240公升氣體(ti)，該電池45V時(shi)失水(shui)并不大）。 在(zai)充(chong)電末期電流下(xia)降區時(shi)，只(zhi)要(yao)降低電壓(ya)到42.5V時(shi)，析氣立即停止，這時(shi)充(chong)電電流稍(shao)小一點，還會(hui)依著(zhu)原(yuan)來的規律下(xia)降。

這里對浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流討論一(yi)下。對于長期處(chu)于浮(fu)(fu)充(chong)(chong)(chong)狀(zhuang)態下的(de)(de)(de)鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組，如后備(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)上(shang)用(yong)的(de)(de)(de)等，對浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)要求(qiu)是嚴格的(de)(de)(de)。據國處(chu)文獻，浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)有-0.2%溫度系數，浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)偏差(cha)太大會造成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池鹽化。而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池屬循環使用(yong)，不(bu)是處(chu)于這種狀(zhuang)態，不(bu)應該用(yong)套用(yong)浮(fu)(fu)充(chong)(chong)(chong)狀(zhuang)態使用(yong)的(de)(de)(de)條(tiao)件(jian)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)設(she)定浮(fu)(fu)充(chong)(chong)(chong)的(de)(de)(de)目的(de)(de)(de)僅是免于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)末期大量析(xi)氣失水(shui)，只要把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)降到析(xi)氣點電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)以(yi)下，但也不(bu)能(neng)低(di)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)而(er)停止向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。前(qian)面(mian)說過，在浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)走(zou)勢基(ji)本還是依(yi)著原曲線下降，一(yi)般還補足5%的(de)(de)(de)容量。所(suo)以(yi)浮(fu)(fu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應在的(de)(de)(de)范圍是低(di)于析(xi)氣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（42.5V），高于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)(dian)(dian)以(yi)后的(de)(de)(de)開路端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（約40V）。

至于(yu)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)(de)大(da)小設定，先看(kan)一下電(dian)(dian)(dian)池制(zhi)造廠家對(dui)(dui)10Ah（12Ah）吸附式小型密封電(dian)(dian)(dian)池對(dui)(dui)充(chong)電(dian)(dian)(dian)時(shi)的(de)(de)技(ji)術要求，通常(chang)規定充(chong)電(dian)(dian)(dian)速率不要大(da)于(yu)0.3C，相當于(yu)4A電(dian)(dian)(dian)流，而充(chong)電(dian)(dian)(dian)器(qi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流在2A左右，遠離極限充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流。充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流在一定范圍內大(da)一點、小一點，充(chong)電(dian)(dian)(dian)時(shi)間長一點、短(duan)一點，沒有很高的(de)(de)要求，有10%的(de)(de)誤差就行了，充(chong)電(dian)(dian)(dian)器(qi)中的(de)(de)電(dian)(dian)(dian)流取樣電(dian)(dian)(dian)阻精(jing)度是5%，電(dian)(dian)(dian)流的(de)(de)精(jing)度不會高于(yu)此。

總而言之(zhi)，不(bu)管哪家生產的(de)鉛酸(suan)閥控(kong)吸附式小(xiao)密(mi)封(feng)電(dian)(dian)(dian)(dian)池(chi)(chi)，其基本結構是完全一樣的(de)，僅極板、框架、滲入的(de)微量元素、漿料配方、硫酸(suan)濃度等有此微小(xiao)差異，而在電(dian)(dian)(dian)(dian)化(hua)學方面都(dou)是一樣的(de)，也就是說它們單(dan)體(ti)的(de)端(duan)電(dian)(dian)(dian)(dian)壓(ya)、充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)、充(chong)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)密(mi)度（動力型）、開始析氣電(dian)(dian)(dian)(dian)壓(ya)點等，不(bu)會有顯著的(de)差異。一個按(an)照前面所(suo)討論的(de)充(chong)電(dian)(dian)(dian)(dian)器，可適應所(suo)有品牌的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，不(bu)存在匹配問題(ti)。

鉛酸蓄電池充電器(qi)認識誤(wu)區(qu)

1、最高充電(dian)電(dian)壓與充入電(dian)量關系不(bu)大。

2、浮(fu)充電壓(ya)與充入電量沒關(guan)系，只要高于(yu)電池(chi)最大(da)開路(lu)端電壓(ya)，低于(yu)開始析氣(qi)點電壓(ya)就行了。

3、浮(fu)充轉(zhuan)換(huan)電(dian)流，僅(jin)是切換(huan)最高充電(dian)電(dian)壓到(dao)浮(fu)充電(dian)壓的設定點，不宜過小或過大，與充電(dian)量也沒(mei)關系。

4、充電電流只要不(bu)超(chao)過0.3C(對10Ah相應(ying)為4A)都是(shi)允許的(de)，不(bu)必要嚴格要求。

所以(yi)，對(dui)于36V閥控式(shi)吸附式(shi)小(xiao)密封電(dian)(dian)池(chi)組充電(dian)(dian)參數推薦如下：

最(zui)高(gao)電壓：43.5V～44.8V

浮充(chong)轉(zhuan)換電流：300mA～500Ma

浮充電壓：41V～42V

充電(dian)電(dian)流(liu)：2A±20%
