鉛(qian)酸蓄電池充電器參數解(jie)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)高充電(dian)(dian)電(dian)(dian)壓值相對誤差(cha)范圍是多少？我們不能(neng)脫離(li)實(shi)際(ji)的(de)工作(zuo)對象，盲(mang)目制定(ding)(ding)出超常規的(de)精度要求。我們接到某電(dian)(dian)動車(che)售后服務部通(tong)知：充電(dian)(dian)器比規定(ding)(ding)電(dian)(dian)壓高0.1V，電(dian)(dian)池因此熱失控而充脹了；也接到通(tong)知說：電(dian)(dian)壓比規定(ding)(ding)定(ding)(ding)低0.1V，電(dian)(dian)池欠(qian)充，提前報廢(fei)。一個千分(fen)之(zhi)幾的(de)誤差(cha)造成如此嚴重后果，真是失之(zhi)毫厘，謬之(zhi)千里之(zhi)外，鉛酸蓄電(dian)(dian)池果真有(you)這么神(shen)秘嗎？為了解開困擾電(dian)(dian)動車(che)充電(dian)(dian)中(zhong)的(de)這個謎團，做如下實(shi)驗。

用(yong)一個水(shui)(shui)槽盛滿(man)水(shui)(shui)，電(dian)池放在水(shui)(shui)中，在電(dian)池上方有一個收集氣(qi)體用(yong)的(de)(de)倒扣的(de)(de)漏斗，漏斗頂(ding)端(duan)裝有可(ke)以計量(liang)氣(qi)體容量(liang)的(de)(de)注(zhu)射針筒(tong)。充(chong)電(dian)用(yong)可(ke)調穩(wen)壓(ya)電(dian)源，用(yong)兩只四位半(ban)數字萬用(yong)表測量(liang)充(chong)電(dian)電(dian)流和充(chong)電(dian)電(dian)壓(ya)。

試(shi)驗時(shi)間(jian)是(shi)(shi)在冬季，水(shui)溫5℃。實(shi)驗條件是(shi)(shi)統一用2A電(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)，最充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓分別(bie)用43V、44V、45V輪循環依次進行，浮充(chong)(chong)轉換電(dian)(dian)(dian)流(liu)一律400mA，記錄下每次的(de)(de)充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)，包(bao)括充(chong)(chong)電(dian)(dian)(dian)末期隨(sui)時(shi)間(jian)電(dian)(dian)(dian)流(liu)下降各點數據(ju)、開始析氣(qi)電(dian)(dian)(dian)壓，按時(shi)間(jian)記錄析氣(qi)量(liang)。電(dian)(dian)(dian)池充(chong)(chong)完后(hou)，用萬分之幾精度(du)的(de)(de)電(dian)(dian)(dian)量(liang)臺記錄放電(dian)(dian)(dian)容(rong)量(liang)。充(chong)(chong)入電(dian)(dian)(dian)量(liang)是(shi)(shi)在計算紙上讀(du)出時(shi)間(jian)電(dian)(dian)(dian)流(liu)曲(qu)線與坐標之間(jian)的(de)(de)面積（電(dian)(dian)(dian)容(rong)量(liang)就(jiu)是(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)對(dui)時(shi)間(jian)的(de)(de)定積分）。

總(zong)而言之(zhi)，不管哪家生(sheng)產的(de)(de)(de)(de)鉛酸閥控(kong)吸附(fu)式(shi)小密(mi)封電(dian)(dian)(dian)(dian)池(chi)，其基本結構是完(wan)全一樣(yang)的(de)(de)(de)(de)，僅極板、框架(jia)、滲入的(de)(de)(de)(de)微量元素、漿料配方、硫酸濃度(du)等(deng)有此微小差(cha)異，而在電(dian)(dian)(dian)(dian)化學方面(mian)都是一樣(yang)的(de)(de)(de)(de)，也就是說(shuo)它們(men)單體的(de)(de)(de)(de)端電(dian)(dian)(dian)(dian)壓(ya)、充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)、充放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)密(mi)度(du)（動力型）、開始析氣電(dian)(dian)(dian)(dian)壓(ya)點等(deng)，不會有顯(xian)著的(de)(de)(de)(de)差(cha)異。一個按照前(qian)面(mian)所討論(lun)的(de)(de)(de)(de)充電(dian)(dian)(dian)(dian)器(qi)，可適應所有品牌的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)，不存在匹配問題。

鉛酸蓄電(dian)池充電(dian)器認識(shi)誤區

1、最高充(chong)電(dian)電(dian)壓與充(chong)入電(dian)量(liang)關(guan)系不大。

2、浮充(chong)電(dian)壓與充(chong)入電(dian)量沒關系，只要高于電(dian)池最大開路(lu)端電(dian)壓，低于開始析氣點電(dian)壓就行了。

3、浮(fu)充轉(zhuan)換電(dian)(dian)流，僅是(shi)切換最高(gao)充電(dian)(dian)電(dian)(dian)壓到浮(fu)充電(dian)(dian)壓的設定點，不宜過小或過大(da)，與充電(dian)(dian)量也沒(mei)關系。

4、充(chong)電電流只要不超過0.3C(對10Ah相(xiang)應為(wei)4A)都是允(yun)許的，不必要嚴(yan)格要求。

所以，對于36V閥控式吸附式小(xiao)密(mi)封電池組充電參數推薦(jian)如下：

最高(gao)電壓：43.5V～44.8V

浮充轉(zhuan)換電流：300mA～500Ma

浮(fu)充電壓(ya)：41V～42V

充(chong)電電流(liu)：2A±20%

以上是對電動車鉛酸蓄電(dian)池(chi)充電(dian)中一(yi)些認(ren)識誤區進(jin)行的(de)試驗(yan)(yan)和分析(xi)，通過以上的(de)試驗(yan)(yan)和分析(xi)能使廣大消費者知道鉛酸蓄電(dian)池(chi)充電(dian)中應注意的(de)一(yi)些問題，以更(geng)好地正(zheng)確使用(yong)充電(dian)器。
