鉛酸蓄電池(chi)充(chong)電器參(can)數解讀

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(chan)廠家的(de)(de)要求也(ye)不一樣(yang)。最高(gao)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓值相(xiang)對(dui)誤(wu)差范圍是多少？我(wo)們(men)不能脫離實(shi)際的(de)(de)工作對(dui)象(xiang)，盲(mang)目制定(ding)(ding)(ding)出超常規(gui)(gui)的(de)(de)精度要求。我(wo)們(men)接(jie)到某(mou)電(dian)(dian)(dian)動車售后(hou)服務部通(tong)(tong)知：充電(dian)(dian)(dian)器(qi)比規(gui)(gui)定(ding)(ding)(ding)電(dian)(dian)(dian)壓高(gao)0.1V，電(dian)(dian)(dian)池(chi)因此(ci)熱失控而充脹了(le)(le)；也(ye)接(jie)到通(tong)(tong)知說：電(dian)(dian)(dian)壓比規(gui)(gui)定(ding)(ding)(ding)定(ding)(ding)(ding)低0.1V，電(dian)(dian)(dian)池(chi)欠充，提前報廢。一個千分之(zhi)(zhi)幾(ji)的(de)(de)誤(wu)差造成如此(ci)嚴(yan)重后(hou)果，真是失之(zhi)(zhi)毫厘，謬之(zhi)(zhi)千里之(zhi)(zhi)外(wai)，鉛酸蓄(xu)電(dian)(dian)(dian)池(chi)果真有這么神秘嗎？為了(le)(le)解開困擾電(dian)(dian)(dian)動車充電(dian)(dian)(dian)中的(de)(de)這個謎團，做(zuo)如下實(shi)驗。

用(yong)(yong)一(yi)(yi)個水(shui)槽盛滿水(shui)，電(dian)池放在水(shui)中(zhong)，在電(dian)池上(shang)方有一(yi)(yi)個收集氣(qi)體用(yong)(yong)的倒扣的漏(lou)斗(dou)，漏(lou)斗(dou)頂端裝有可以計量(liang)氣(qi)體容量(liang)的注射針筒(tong)。充(chong)電(dian)用(yong)(yong)可調穩壓(ya)(ya)電(dian)源，用(yong)(yong)兩只四位半數字(zi)萬用(yong)(yong)表(biao)測量(liang)充(chong)電(dian)電(dian)流(liu)和充(chong)電(dian)電(dian)壓(ya)(ya)。

試(shi)驗時間(jian)是在冬季，水溫5℃。實(shi)驗條件是統一用2A電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，最充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓分別(bie)用43V、44V、45V輪(lun)循環依(yi)次進行，浮充(chong)(chong)(chong)轉換電(dian)(dian)(dian)(dian)(dian)流(liu)一律400mA，記(ji)錄(lu)(lu)下(xia)(xia)每次的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)，包括(kuo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)末期隨時間(jian)電(dian)(dian)(dian)(dian)(dian)流(liu)下(xia)(xia)降各(ge)點(dian)數據、開始(shi)析(xi)氣電(dian)(dian)(dian)(dian)(dian)壓，按時間(jian)記(ji)錄(lu)(lu)析(xi)氣量。電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)完后，用萬(wan)分之幾精(jing)度的(de)電(dian)(dian)(dian)(dian)(dian)量臺記(ji)錄(lu)(lu)放電(dian)(dian)(dian)(dian)(dian)容量。充(chong)(chong)(chong)入電(dian)(dian)(dian)(dian)(dian)量是在計算紙上讀出時間(jian)電(dian)(dian)(dian)(dian)(dian)流(liu)曲線與坐標之間(jian)的(de)面(mian)積（電(dian)(dian)(dian)(dian)(dian)容量就是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)對(dui)時間(jian)的(de)定積分）。

電(dian)(dian)池在(zai)42.5V～43.5V時開(kai)始析(xi)氣，而析(xi)氣的速度與充(chong)電(dian)(dian)電(dian)(dian)壓(ya)有關。到(dao)充(chong)電(dian)(dian)結束時，總(zong)析(xi)氣量(liang)(liang)與充(chong)電(dian)(dian)最高電(dian)(dian)壓(ya)有關，43V與45V總(zong)析(xi)氣量(liang)(liang)相(xiang)差10位（注：以單格允許極限失水10克，18格相(xiang)當240公升氣體，該電(dian)(dian)池45V時失水并不大(da)）。 在(zai)充(chong)電(dian)(dian)末期電(dian)(dian)流下降(jiang)區時，只要降(jiang)低(di)電(dian)(dian)壓(ya)到(dao)42.5V時，析(xi)氣立即停(ting)止，這時充(chong)電(dian)(dian)電(dian)(dian)流稍小(xiao)一點，還(huan)會(hui)依(yi)著原來的規(gui)律下降(jiang)。

這里對浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)、浮充(chong)(chong)電(dian)(dian)(dian)(dian)流(liu)討(tao)論一(yi)下。對于(yu)(yu)長期(qi)處(chu)于(yu)(yu)浮充(chong)(chong)狀(zhuang)態下的(de)(de)(de)鉛(qian)酸電(dian)(dian)(dian)(dian)池(chi)組，如后備(bei)電(dian)(dian)(dian)(dian)源上用的(de)(de)(de)等(deng)，對浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)要求(qiu)是(shi)嚴格的(de)(de)(de)。據國處(chu)文獻，浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)有-0.2%溫(wen)度(du)系數，浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)偏差太大(da)會造(zao)成電(dian)(dian)(dian)(dian)池(chi)鹽化。而電(dian)(dian)(dian)(dian)動(dong)車用的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)屬循環使用，不是(shi)處(chu)于(yu)(yu)這種狀(zhuang)態，不應該用套用浮充(chong)(chong)狀(zhuang)態使用的(de)(de)(de)條件，充(chong)(chong)電(dian)(dian)(dian)(dian)器設定(ding)浮充(chong)(chong)的(de)(de)(de)目的(de)(de)(de)僅(jin)是(shi)免于(yu)(yu)充(chong)(chong)電(dian)(dian)(dian)(dian)末期(qi)大(da)量析(xi)氣失(shi)水，只要把電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)降(jiang)到析(xi)氣點電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)以下，但(dan)也不能低(di)于(yu)(yu)電(dian)(dian)(dian)(dian)池(chi)端電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)而停止(zhi)向(xiang)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)。前面說過，在(zai)浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)下，充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)走(zou)勢基本(ben)還是(shi)依著原曲線下降(jiang)，一(yi)般(ban)還補足(zu)5%的(de)(de)(de)容量。所以浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)應在(zai)的(de)(de)(de)范圍是(shi)低(di)于(yu)(yu)析(xi)氣電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)（42.5V），高于(yu)(yu)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)以后的(de)(de)(de)開路端電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)（約40V）。

至于充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)的(de)(de)大(da)(da)小設定，先看一(yi)下電(dian)(dian)(dian)(dian)池制(zhi)造(zao)廠家對10Ah（12Ah）吸附式小型密封電(dian)(dian)(dian)(dian)池對充(chong)(chong)電(dian)(dian)(dian)(dian)時的(de)(de)技術要求(qiu)，通常規(gui)定充(chong)(chong)電(dian)(dian)(dian)(dian)速率不要大(da)(da)于0.3C，相(xiang)當于4A電(dian)(dian)(dian)(dian)流(liu)，而充(chong)(chong)電(dian)(dian)(dian)(dian)器充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)在(zai)2A左右，遠離極限(xian)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)。充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)在(zai)一(yi)定范圍內大(da)(da)一(yi)點(dian)、小一(yi)點(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)長(chang)一(yi)點(dian)、短一(yi)點(dian)，沒有很高(gao)(gao)的(de)(de)要求(qiu)，有10%的(de)(de)誤差就行了，充(chong)(chong)電(dian)(dian)(dian)(dian)器中的(de)(de)電(dian)(dian)(dian)(dian)流(liu)取樣電(dian)(dian)(dian)(dian)阻精(jing)度是5%，電(dian)(dian)(dian)(dian)流(liu)的(de)(de)精(jing)度不會高(gao)(gao)于此。

總而言之，不(bu)管哪家生產的(de)(de)鉛(qian)酸閥控(kong)吸附式小密封電池，其基(ji)本(ben)結(jie)構是(shi)完全一(yi)樣的(de)(de)，僅極板、框架(jia)、滲入的(de)(de)微(wei)量元素、漿料(liao)配方、硫(liu)酸濃度等(deng)(deng)有(you)此(ci)微(wei)小差異，而在電化學方面(mian)都(dou)是(shi)一(yi)樣的(de)(de)，也(ye)就是(shi)說它(ta)們(men)單體(ti)的(de)(de)端(duan)電壓、充(chong)電電壓、充(chong)放電電流密度（動力型）、開始析(xi)氣(qi)電壓點等(deng)(deng)，不(bu)會有(you)顯著的(de)(de)差異。一(yi)個按(an)照前面(mian)所(suo)討論的(de)(de)充(chong)電器(qi)，可適應所(suo)有(you)品牌的(de)(de)電池，不(bu)存在匹配問題。

鉛酸蓄電池充電器認識誤(wu)區

1、最高充電電壓與充入電量關系不大(da)。

2、浮充電壓與充入(ru)電量(liang)沒關系，只要高于電池(chi)最(zui)大開路(lu)端電壓，低于開始析氣點(dian)電壓就(jiu)行(xing)了。

3、浮(fu)充轉換電流，僅(jin)是(shi)切換最高充電電壓到浮(fu)充電壓的設定點(dian)，不宜(yi)過小或過大，與充電量(liang)也沒關系。

4、充電電流只要(yao)不超過0.3C(對10Ah相應為4A)都(dou)是允許的，不必要(yao)嚴格要(yao)求。

所以，對于36V閥(fa)控式(shi)吸附式(shi)小密封(feng)電池組充電參數(shu)推(tui)薦(jian)如(ru)下：

最(zui)高電壓：43.5V～44.8V

浮充轉換電流：300mA～500Ma

浮充(chong)電壓：41V～42V

充電電流：2A±20%

以上是對電動車鉛酸(suan)蓄電(dian)池(chi)充(chong)電(dian)中一(yi)(yi)些認識(shi)誤區(qu)進行的(de)試驗和分(fen)析，通過以(yi)(yi)上的(de)試驗和分(fen)析能(neng)使廣大(da)消費者知道鉛酸(suan)蓄電(dian)池(chi)充(chong)電(dian)中應注意的(de)一(yi)(yi)些問題，以(yi)(yi)更好(hao)地正(zheng)確使用充(chong)電(dian)器。
