鉛酸蓄(xu)電池充電器(qi)參數解讀(du)

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(sheng)產廠家的(de)(de)(de)要求(qiu)也(ye)不一樣。最高充(chong)(chong)(chong)電(dian)電(dian)壓值相對(dui)誤差范(fan)圍是多(duo)少？我們不能脫(tuo)離(li)實際(ji)的(de)(de)(de)工作對(dui)象，盲目制定(ding)出(chu)超常規(gui)的(de)(de)(de)精(jing)度要求(qiu)。我們接(jie)(jie)到某電(dian)動(dong)車售后(hou)服務部通知：充(chong)(chong)(chong)電(dian)器(qi)比(bi)規(gui)定(ding)電(dian)壓高0.1V，電(dian)池因此熱失(shi)控而充(chong)(chong)(chong)脹(zhang)了；也(ye)接(jie)(jie)到通知說：電(dian)壓比(bi)規(gui)定(ding)定(ding)低(di)0.1V，電(dian)池欠充(chong)(chong)(chong)，提前報廢。一個千(qian)分(fen)之(zhi)(zhi)幾的(de)(de)(de)誤差造(zao)成(cheng)如(ru)此嚴(yan)重后(hou)果，真(zhen)是失(shi)之(zhi)(zhi)毫厘(li)，謬之(zhi)(zhi)千(qian)里之(zhi)(zhi)外，鉛酸(suan)蓄電(dian)池果真(zhen)有(you)這么神秘嗎？為了解開困擾電(dian)動(dong)車充(chong)(chong)(chong)電(dian)中的(de)(de)(de)這個謎團(tuan)，做如(ru)下實驗(yan)。

用(yong)(yong)一個水(shui)槽盛滿(man)水(shui)，電(dian)(dian)池放在水(shui)中，在電(dian)(dian)池上(shang)方有一個收集(ji)氣體(ti)用(yong)(yong)的倒扣的漏(lou)斗，漏(lou)斗頂端裝有可以(yi)計量(liang)(liang)氣體(ti)容量(liang)(liang)的注射針筒。充(chong)電(dian)(dian)用(yong)(yong)可調穩壓(ya)電(dian)(dian)源(yuan)，用(yong)(yong)兩只四位半數字萬用(yong)(yong)表測量(liang)(liang)充(chong)電(dian)(dian)電(dian)(dian)流(liu)和(he)充(chong)電(dian)(dian)電(dian)(dian)壓(ya)。

試驗(yan)時間(jian)是在(zai)冬季(ji)，水溫5℃。實驗(yan)條件是統一用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(ya)分(fen)別用43V、44V、45V輪(lun)循環依(yi)次進行，浮充(chong)(chong)轉(zhuan)換電(dian)(dian)(dian)(dian)流(liu)一律400mA，記(ji)錄下(xia)每次的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)，包括充(chong)(chong)電(dian)(dian)(dian)(dian)末期(qi)隨時間(jian)電(dian)(dian)(dian)(dian)流(liu)下(xia)降各點數據(ju)、開始析(xi)氣電(dian)(dian)(dian)(dian)壓(ya)，按時間(jian)記(ji)錄析(xi)氣量(liang)(liang)。電(dian)(dian)(dian)(dian)池充(chong)(chong)完后，用萬分(fen)之幾精度的(de)(de)電(dian)(dian)(dian)(dian)量(liang)(liang)臺記(ji)錄放電(dian)(dian)(dian)(dian)容(rong)量(liang)(liang)。充(chong)(chong)入電(dian)(dian)(dian)(dian)量(liang)(liang)是在(zai)計算(suan)紙(zhi)上讀出時間(jian)電(dian)(dian)(dian)(dian)流(liu)曲線與坐(zuo)標之間(jian)的(de)(de)面積（電(dian)(dian)(dian)(dian)容(rong)量(liang)(liang)就是充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)對時間(jian)的(de)(de)定(ding)積分(fen)）。

得(de)到(dao)試(shi)(shi)(shi)(shi)驗(yan)數據(ju)后(hou)，最(zui)(zui)感到(dao)驚異的(de)(de)是(shi)(shi)(shi)：充(chong)入電(dian)(dian)(dian)量(liang)的(de)(de)多少(shao)幾(ji)乎(hu)與充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)無(wu)關。很多人(ren)認(ren)為充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)低電(dian)(dian)(dian)池(chi)(chi)會(hui)充(chong)不(bu)滿(man)，電(dian)(dian)(dian)池(chi)(chi)會(hui)提前鹽化報廢，特(te)別是(shi)(shi)(shi)在冬(dong)季氣溫(wen)較(jiao)低的(de)(de)時候。而(er)這(zhe)次試(shi)(shi)(shi)(shi)驗(yan)正好是(shi)(shi)(shi)在冬(dong)季，水溫(wen)只(zhi)(zhi)有5℃，試(shi)(shi)(shi)(shi)驗(yan)的(de)(de)中(zhong)心電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值是(shi)(shi)(shi)44V，上下偏差(cha)1V，相(xiang)對(dui)誤差(cha)是(shi)(shi)(shi)2.3%。在用43V和(he)45V充(chong)電(dian)(dian)(dian)的(de)(de)情況下，充(chong)入電(dian)(dian)(dian)量(liang)和(he)放出電(dian)(dian)(dian)量(liang)相(xiang)差(cha)無(wu)幾(ji)，與大(da)(da)家公認(ren)的(de)(de)看法(fa)大(da)(da)相(xiang)徑庭，試(shi)(shi)(shi)(shi)驗(yan)是(shi)(shi)(shi)用的(de)(de)同一(yi)組電(dian)(dian)(dian)池(chi)(chi)，同樣(yang)的(de)(de)充(chong)、放電(dian)(dian)(dian)條(tiao)件，輪(lun)番做同樣(yang)的(de)(de)測試(shi)(shi)(shi)(shi)，實(shi)驗(yan)數據(ju)重復同樣(yang)的(de)(de)規(gui)律，可排除偶然因素干擾，試(shi)(shi)(shi)(shi)驗(yan)數據(ju)是(shi)(shi)(shi)準確可信的(de)(de)。從電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)原理上看，只(zhi)(zhi)要充(chong)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)高(gao)(gao)于電(dian)(dian)(dian)池(chi)(chi)端電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，都會(hui)給電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)，一(yi)直到(dao)電(dian)(dian)(dian)池(chi)(chi)中(zhong)的(de)(de)活(huo)性(xing)物(wu)質轉換完(wan)成。充(chong)電(dian)(dian)(dian)最(zui)(zui)高(gao)(gao)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，也就(jiu)是(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)源開始(shi)由恒流區轉變(bian)到(dao)恒壓(ya)(ya)(ya)(ya)區，這(zhe)種轉變(bian)是(shi)(shi)(shi)由電(dian)(dian)(dian)池(chi)(chi)自身充(chong)入電(dian)(dian)(dian)量(liang)多少(shao)、活(huo)性(xing)物(wu)質反(fan)(fan)應了多少(shao)決(jue)定(ding)的(de)(de)，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)(de)高(gao)(gao)低，僅是(shi)(shi)(shi)能進行電(dian)(dian)(dian)化學反(fan)(fan)應的(de)(de)條(tiao)件，只(zhi)(zhi)要高(gao)(gao)于電(dian)(dian)(dian)池(chi)(chi)開路電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)就(jiu)會(hui)給電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)，多少(shao)物(wu)質能參與反(fan)(fan)應由電(dian)(dian)(dian)池(chi)(chi)自身決(jue)定(ding)。從這(zhe)個思路理解，就(jiu)不(bu)難得(de)出，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)高(gao)(gao)低對(dui)電(dian)(dian)(dian)池(chi)(chi)容量(liang)沒有多大(da)(da)影響。

電(dian)(dian)池在42.5V～43.5V時(shi)開始析氣(qi)(qi)(qi)，而(er)析氣(qi)(qi)(qi)的(de)速度(du)與(yu)充(chong)(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)有(you)(you)關。到充(chong)(chong)電(dian)(dian)結束時(shi)，總(zong)(zong)析氣(qi)(qi)(qi)量(liang)與(yu)充(chong)(chong)電(dian)(dian)最高(gao)電(dian)(dian)壓(ya)(ya)有(you)(you)關，43V與(yu)45V總(zong)(zong)析氣(qi)(qi)(qi)量(liang)相(xiang)差(cha)10位（注：以(yi)單格允(yun)許極(ji)限(xian)失水(shui)10克，18格相(xiang)當240公升氣(qi)(qi)(qi)體，該電(dian)(dian)池45V時(shi)失水(shui)并(bing)不(bu)大）。 在充(chong)(chong)電(dian)(dian)末(mo)期電(dian)(dian)流(liu)下降區時(shi)，只(zhi)要降低電(dian)(dian)壓(ya)(ya)到42.5V時(shi)，析氣(qi)(qi)(qi)立(li)即停止，這時(shi)充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)稍小一點，還會依著原(yuan)來的(de)規律下降。

這(zhe)里對浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)流討論一下。對于長期(qi)處(chu)于浮充(chong)(chong)(chong)狀態下的(de)鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組，如后(hou)備電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)上用的(de)等，對浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)要求(qiu)是(shi)嚴格(ge)的(de)。據國(guo)處(chu)文獻，浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)有(you)-0.2%溫(wen)度系數，浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)偏差太大(da)會造成電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)鹽化。而電(dian)(dian)(dian)(dian)(dian)(dian)動車用的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)屬循(xun)環(huan)使用，不是(shi)處(chu)于這(zhe)種(zhong)狀態，不應該用套用浮充(chong)(chong)(chong)狀態使用的(de)條件，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)設定(ding)浮充(chong)(chong)(chong)的(de)目(mu)的(de)僅(jin)是(shi)免于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)末期(qi)大(da)量析氣(qi)(qi)失水(shui)，只(zhi)要把電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降到析氣(qi)(qi)點電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)以(yi)下，但也不能低(di)于電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)而停(ting)止向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。前面說過，在浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流的(de)走勢基(ji)本(ben)還是(shi)依著原曲線下降，一般還補足5%的(de)容量。所以(yi)浮充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)應在的(de)范圍是(shi)低(di)于析氣(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)（42.5V），高于電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)(dian)以(yi)后(hou)的(de)開(kai)路端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)（約(yue)40V）。

至于(yu)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)大(da)(da)小(xiao)設(she)定，先看一(yi)下電(dian)(dian)(dian)池(chi)制造廠家對(dui)10Ah（12Ah）吸(xi)附式小(xiao)型(xing)密封電(dian)(dian)(dian)池(chi)對(dui)充(chong)電(dian)(dian)(dian)時的(de)技術(shu)要(yao)求(qiu)(qiu)，通(tong)常(chang)規定充(chong)電(dian)(dian)(dian)速率不(bu)要(yao)大(da)(da)于(yu)0.3C，相當于(yu)4A電(dian)(dian)(dian)流，而充(chong)電(dian)(dian)(dian)器充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流在(zai)2A左右，遠(yuan)離極限(xian)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流。充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流在(zai)一(yi)定范圍內大(da)(da)一(yi)點、小(xiao)一(yi)點，充(chong)電(dian)(dian)(dian)時間長一(yi)點、短一(yi)點，沒有很高(gao)的(de)要(yao)求(qiu)(qiu)，有10%的(de)誤差就行了(le)，充(chong)電(dian)(dian)(dian)器中的(de)電(dian)(dian)(dian)流取樣(yang)電(dian)(dian)(dian)阻精度是5%，電(dian)(dian)(dian)流的(de)精度不(bu)會(hui)高(gao)于(yu)此(ci)。

總而言之，不(bu)管哪家生產的(de)(de)鉛(qian)酸(suan)閥控吸(xi)附式小密封電(dian)(dian)池，其基本結構是完全(quan)一樣的(de)(de)，僅極板、框(kuang)架、滲入(ru)的(de)(de)微量(liang)元(yuan)素、漿料配(pei)方(fang)、硫酸(suan)濃度等有此微小差異，而在電(dian)(dian)化(hua)學方(fang)面都(dou)是一樣的(de)(de)，也就是說它們單體的(de)(de)端電(dian)(dian)壓(ya)(ya)、充(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)、充(chong)放電(dian)(dian)電(dian)(dian)流(liu)密度（動力型(xing)）、開始析氣電(dian)(dian)壓(ya)(ya)點等，不(bu)會有顯著的(de)(de)差異。一個按照前(qian)面所(suo)討論的(de)(de)充(chong)電(dian)(dian)器，可適應所(suo)有品牌的(de)(de)電(dian)(dian)池，不(bu)存(cun)在匹配(pei)問題。

鉛酸(suan)蓄(xu)電(dian)池充電(dian)器認識誤區(qu)

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

2、浮充(chong)電(dian)(dian)壓(ya)與(yu)充(chong)入電(dian)(dian)量(liang)沒關系(xi)，只要高于電(dian)(dian)池最(zui)大(da)開路(lu)端電(dian)(dian)壓(ya)，低于開始析氣點電(dian)(dian)壓(ya)就行了。

3、浮(fu)充(chong)(chong)轉換電流(liu)，僅是切(qie)換最高充(chong)(chong)電電壓到(dao)浮(fu)充(chong)(chong)電壓的設定(ding)點，不宜過(guo)小或過(guo)大(da)，與(yu)充(chong)(chong)電量(liang)也沒(mei)關系(xi)。

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

所以，對(dui)于36V閥控(kong)式(shi)吸附式(shi)小密(mi)封電池組充電參數推薦(jian)如下：

最高電壓：43.5V～44.8V

浮(fu)充轉(zhuan)換電流：300mA～500Ma

浮充電壓(ya)：41V～42V

充電電流：2A±20%

以上是對電動車鉛酸(suan)蓄電池充電中一些認識(shi)誤區進(jin)行的(de)試驗和分析，通過以上(shang)的(de)試驗和分析能使(shi)廣大消(xiao)費(fei)者知道鉛酸(suan)蓄電池充電中應注意的(de)一些問(wen)題，以更好地正確使(shi)用充電器(qi)。
