鉛酸蓄電池的特點

當鉛酸蓄電池的容量放出70%以上時就應及時對其進行(xing)充(chong)電。并且按如(ru)下三(san)階段(duan)進行(xing)：第一階段(duan)為恒流充(chong)電，第二階段(duan)為恒壓充(chong)電，第三(san)：階段(duan)為滑流電。否則，會(hui)嚴重影響莆(pu)電池的(de)使用壽命門前廣泛(fan)用于鉛(qian)酸電池充(chong)電器的(de)UC3842集成電路可直接驅動MOS開關管，在穩(wen)定輸(shu)出電壓的同(tong)時，具有負(fu)載電流控制能力(li)（稱其為電流控制型開關電源驅動器）。無疑具有獨(du)特的優勢(shi)：只要用極少的外圍(wei)元(yuan)件即可實現(xian)(xian)恒壓輸(shu)出和控制充電電流的目的。使(shi)充電器能夠按照鉛酸莆電池性能要求，達到接步驟地實現(xian)(xian)智能充電的目的。

鉛(qian)酸蓄(xu)電池(chi)充電器參數解讀

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，各電池生產廠家的(de)(de)要求(qiu)也不一樣(yang)。最高充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓值(zhi)相對誤(wu)差范圍是(shi)多(duo)少？我們(men)不能脫(tuo)離實際的(de)(de)工作對象，盲目制定出超常規的(de)(de)精度要求(qiu)。我們(men)接(jie)到(dao)某電(dian)(dian)(dian)(dian)(dian)動車售后(hou)服務部(bu)通知：充電(dian)(dian)(dian)(dian)(dian)器比(bi)規定電(dian)(dian)(dian)(dian)(dian)壓高0.1V，電(dian)(dian)(dian)(dian)(dian)池因此熱失控而充脹了(le)；也接(jie)到(dao)通知說：電(dian)(dian)(dian)(dian)(dian)壓比(bi)規定定低0.1V，電(dian)(dian)(dian)(dian)(dian)池欠充，提(ti)前報廢。一個千(qian)分之(zhi)幾(ji)的(de)(de)誤(wu)差造成如此嚴重后(hou)果(guo)，真是(shi)失之(zhi)毫厘，謬之(zhi)千(qian)里之(zhi)外(wai)，鉛(qian)酸蓄電(dian)(dian)(dian)(dian)(dian)池果(guo)真有這么神秘(mi)嗎？為(wei)了(le)解開困擾(rao)電(dian)(dian)(dian)(dian)(dian)動車充電(dian)(dian)(dian)(dian)(dian)中(zhong)的(de)(de)這個謎團，做如下實驗。

用(yong)一(yi)(yi)個(ge)水(shui)槽盛(sheng)滿(man)水(shui)，電池放在水(shui)中，在電池上方有一(yi)(yi)個(ge)收集(ji)氣(qi)體用(yong)的(de)倒扣的(de)漏斗，漏斗頂端裝有可以計量氣(qi)體容量的(de)注(zhu)射(she)針筒(tong)。充電用(yong)可調穩壓電源，用(yong)兩只四位(wei)半(ban)數字(zi)萬用(yong)表測量充電電流(liu)和充電電壓。

試驗時(shi)間(jian)是在(zai)冬季，水溫(wen)5℃。實驗條件是統一用(yong)2A電(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)，最充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓分(fen)別用(yong)43V、44V、45V輪循環(huan)依次(ci)進行，浮充(chong)(chong)轉換電(dian)(dian)(dian)(dian)流(liu)一律400mA，記(ji)(ji)錄(lu)(lu)下每次(ci)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)，包括充(chong)(chong)電(dian)(dian)(dian)(dian)末期隨時(shi)間(jian)電(dian)(dian)(dian)(dian)流(liu)下降各點(dian)數據、開始析氣電(dian)(dian)(dian)(dian)壓，按時(shi)間(jian)記(ji)(ji)錄(lu)(lu)析氣量(liang)。電(dian)(dian)(dian)(dian)池充(chong)(chong)完后，用(yong)萬分(fen)之(zhi)幾精度的(de)(de)電(dian)(dian)(dian)(dian)量(liang)臺記(ji)(ji)錄(lu)(lu)放電(dian)(dian)(dian)(dian)容量(liang)。充(chong)(chong)入電(dian)(dian)(dian)(dian)量(liang)是在(zai)計算紙(zhi)上讀出(chu)時(shi)間(jian)電(dian)(dian)(dian)(dian)流(liu)曲線與坐標之(zhi)間(jian)的(de)(de)面積（電(dian)(dian)(dian)(dian)容量(liang)就(jiu)是充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)對時(shi)間(jian)的(de)(de)定積分(fen)）。

電(dian)(dian)池在42.5V～43.5V時(shi)(shi)(shi)開始(shi)析(xi)氣，而析(xi)氣的速度與充(chong)(chong)電(dian)(dian)電(dian)(dian)壓(ya)有(you)關。到充(chong)(chong)電(dian)(dian)結束(shu)時(shi)(shi)(shi)，總析(xi)氣量與充(chong)(chong)電(dian)(dian)最高電(dian)(dian)壓(ya)有(you)關，43V與45V總析(xi)氣量相差10位（注：以單格(ge)允許極限失(shi)水10克，18格(ge)相當240公升氣體，該電(dian)(dian)池45V時(shi)(shi)(shi)失(shi)水并(bing)不大）。 在充(chong)(chong)電(dian)(dian)末期電(dian)(dian)流下降(jiang)區(qu)時(shi)(shi)(shi)，只要降(jiang)低電(dian)(dian)壓(ya)到42.5V時(shi)(shi)(shi)，析(xi)氣立即停止，這時(shi)(shi)(shi)充(chong)(chong)電(dian)(dian)電(dian)(dian)流稍(shao)小一(yi)點，還會依(yi)著原來的規律下降(jiang)。

這(zhe)里對(dui)浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)討論一下(xia)。對(dui)于(yu)長期(qi)處于(yu)浮(fu)充(chong)(chong)狀態下(xia)的(de)(de)(de)鉛酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組，如后備電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)上用(yong)的(de)(de)(de)等(deng)，對(dui)浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)要(yao)求是嚴格的(de)(de)(de)。據國處文獻，浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)有-0.2%溫度系數，浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)偏差太大(da)會造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池鹽化。而電(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(shi)用(yong)，不是處于(yu)這(zhe)種(zhong)狀態，不應該(gai)用(yong)套用(yong)浮(fu)充(chong)(chong)狀態使(shi)用(yong)的(de)(de)(de)條件，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器設定浮(fu)充(chong)(chong)的(de)(de)(de)目的(de)(de)(de)僅是免于(yu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)末期(qi)大(da)量析(xi)氣(qi)(qi)失水，只要(yao)把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)降到析(xi)氣(qi)(qi)點電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)以下(xia)，但也(ye)不能低于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)而停止向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。前(qian)面說過，在(zai)浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下(xia)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)走勢(shi)基本還(huan)是依(yi)著原曲線下(xia)降，一般(ban)還(huan)補(bu)足5%的(de)(de)(de)容量。所以浮(fu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應在(zai)的(de)(de)(de)范圍是低于(yu)析(xi)氣(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（42.5V），高于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)(dian)(dian)以后的(de)(de)(de)開(kai)路端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（約(yue)40V）。

至(zhi)于充(chong)(chong)電(dian)電(dian)流(liu)(liu)的(de)(de)大(da)小設定，先看一(yi)下電(dian)池制造廠(chang)家對10Ah（12Ah）吸(xi)附(fu)式(shi)小型密封電(dian)池對充(chong)(chong)電(dian)時的(de)(de)技(ji)術要(yao)求(qiu)，通常(chang)規定充(chong)(chong)電(dian)速率不(bu)要(yao)大(da)于0.3C，相當于4A電(dian)流(liu)(liu)，而(er)充(chong)(chong)電(dian)器充(chong)(chong)電(dian)電(dian)流(liu)(liu)在2A左右(you)，遠離極限充(chong)(chong)電(dian)電(dian)流(liu)(liu)。充(chong)(chong)電(dian)電(dian)流(liu)(liu)在一(yi)定范(fan)圍(wei)內大(da)一(yi)點、小一(yi)點，充(chong)(chong)電(dian)時間(jian)長(chang)一(yi)點、短一(yi)點，沒(mei)有很高的(de)(de)要(yao)求(qiu)，有10%的(de)(de)誤(wu)差就行了，充(chong)(chong)電(dian)器中的(de)(de)電(dian)流(liu)(liu)取樣電(dian)阻精度是(shi)5%，電(dian)流(liu)(liu)的(de)(de)精度不(bu)會高于此。

總而言之，不(bu)(bu)管(guan)哪家生產的(de)鉛(qian)酸(suan)(suan)閥控吸附式小密封(feng)電(dian)(dian)池(chi)，其基(ji)本結(jie)構是(shi)(shi)完全一樣(yang)的(de)，僅極板、框架(jia)、滲(shen)入的(de)微量元素、漿料配(pei)方、硫酸(suan)(suan)濃度等有(you)此微小差(cha)(cha)異(yi)，而在電(dian)(dian)化(hua)學(xue)方面(mian)都(dou)是(shi)(shi)一樣(yang)的(de)，也就是(shi)(shi)說它們單體的(de)端電(dian)(dian)壓(ya)、充(chong)電(dian)(dian)電(dian)(dian)壓(ya)、充(chong)放電(dian)(dian)電(dian)(dian)流密度（動(dong)力(li)型）、開(kai)始析氣電(dian)(dian)壓(ya)點等，不(bu)(bu)會有(you)顯著(zhu)的(de)差(cha)(cha)異(yi)。一個(ge)按照(zhao)前面(mian)所討論的(de)充(chong)電(dian)(dian)器，可適(shi)應(ying)所有(you)品牌的(de)電(dian)(dian)池(chi)，不(bu)(bu)存在匹(pi)配(pei)問題。

鉛酸蓄電池(chi)充電器認識誤區

1、最(zui)高充(chong)電(dian)電(dian)壓(ya)與充(chong)入電(dian)量關系不大。

2、浮(fu)充(chong)電(dian)壓(ya)與(yu)充(chong)入電(dian)量沒關系(xi)，只要高于電(dian)池最大開路端電(dian)壓(ya)，低于開始析氣點(dian)電(dian)壓(ya)就行了。

3、浮(fu)充轉換電(dian)流，僅(jin)是切換最高充電(dian)電(dian)壓到浮(fu)充電(dian)壓的設定點，不宜過小(xiao)或過大，與充電(dian)量也沒(mei)關系。

4、充(chong)電電流只要不超(chao)過0.3C(對10Ah相應為4A)都是允許的，不必要嚴格要求。

所(suo)以，對(dui)于(yu)36V閥(fa)控式吸附式小密封(feng)電(dian)(dian)池組充電(dian)(dian)參數推薦如下：

最高電壓：43.5V～44.8V

浮充轉換電流(liu)：300mA～500Ma

浮充(chong)電壓：41V～42V

充(chong)電(dian)電(dian)流：2A±20%

以上是對電動車鉛酸蓄電池充(chong)電中一些(xie)認識誤區進行(xing)的試(shi)驗和分析，通過以(yi)上的試(shi)驗和分析能使廣大消費者知道(dao)鉛酸蓄電池充(chong)電中應注意(yi)的一些(xie)問題，以(yi)更好地(di)正確使用充(chong)電器。
