鉛酸蓄電池容量(liang)大(da)小(xiao)和(he)放電(dian)(dian)(dian)(dian)量(liang)大(da)小(xiao)相信很多(duo)朋友都想知道，特別(bie)是用(yong)在電(dian)(dian)(dian)(dian)動車(che)方(fang)面(mian)的，大(da)家(jia)更關(guan)心鉛(qian)酸(suan)(suan)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)能開多(duo)久了(le)。目前電(dian)(dian)(dian)(dian)動車(che)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)有鉛(qian)酸(suan)(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)兩種！鉛(qian)酸(suan)(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)有12AH，14AH，20AH，24Ah，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)就不一定了(le)，因為鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)可以自己喜歡任意組(zu)合得到(dao)大(da)容量(liang)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)比如48V40Ah，72V80Ah等。

要想了解鉛酸(suan)蓄電池容(rong)量(liang)的(de)大小(xiao)和(he)放電量(liang)，需(xu)要對鉛酸(suan)蓄電池的(de)性能知識方面做了解。

電(dian)(dian)(dian)動(dong)(dong)(dong)車蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)容(rong)量(liang)表(biao)(biao)示蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)儲存電(dian)(dian)(dian)能的(de)多少，即(ji)(ji)電(dian)(dian)(dian)動(dong)(dong)(dong)車電(dian)(dian)(dian)池(chi)(chi)在(zai)(zai)完全(quan)充電(dian)(dian)(dian)后，以一(yi)定(ding)的(de)電(dian)(dian)(dian)池(chi)(chi)值連續放(fang)(fang)電(dian)(dian)(dian)，從(cong)放(fang)(fang)電(dian)(dian)(dian)開始(shi)到(dao)電(dian)(dian)(dian)壓降至規定(ding)的(de)終止(zhi)電(dian)(dian)(dian)壓為(wei)(wei)止(zhi)（無法驅動(dong)(dong)(dong)電(dian)(dian)(dian)動(dong)(dong)(dong)車為(wei)(wei)止(zhi)），放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流與時(shi)(shi)間的(de)乘積值，表(biao)(biao)示電(dian)(dian)(dian)動(dong)(dong)(dong)車蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)容(rong)量(liang)單(dan)(dan)位為(wei)(wei)安培·小(xiao)時(shi)(shi)，通常用(yong)“Ah”表(biao)(biao)示。電(dian)(dian)(dian)動(dong)(dong)(dong)車專用(yong)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)完全(quan)充電(dian)(dian)(dian)后，在(zai)(zai)溫度為(wei)(wei)（25±2）℃的(de)環境中靜置1～4h，然后以1/2蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)額定(ding)容(rong)量(liang)（2小(xiao)時(shi)(shi)率(lv)）的(de)恒定(ding)電(dian)(dian)(dian)流（A）放(fang)(fang)電(dian)(dian)(dian)到(dao)單(dan)(dan)體蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)平(ping)均電(dian)(dian)(dian)壓達(da)1.6V（6V蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)為(wei)(wei)4.8V，12為(wei)(wei)9.6V）終止(zhi)，記錄放(fang)(fang)電(dian)(dian)(dian)時(shi)(shi)間。新電(dian)(dian)(dian)動(dong)(dong)(dong)車蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)在(zai)(zai)三次試驗中，放(fang)(fang)電(dian)(dian)(dian)時(shi)(shi)間有一(yi)次大于120min即(ji)(ji)為(wei)(wei)合格。實(shi)際電(dian)(dian)(dian)動(dong)(dong)(dong)車放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流數乘以實(shi)際放(fang)(fang)電(dian)(dian)(dian)小(xiao)時(shi)(shi)數即(ji)(ji)為(wei)(wei)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)實(shi)際容(rong)量(liang)。

這(zhe)個算法(fa)是(shi)指在理想狀態下的(de)數值，在實際(ji)應用過程中，會因為電(dian)動車搭載重量(liang)的(de)不(bu)同、溫度的(de)不(bu)同和路(lu)況的(de)不(bu)同等，導(dao)致鉛酸蓄電(dian)池能放出來(lai)的(de)電(dian)量(liang)（容量(liang)）大小是(shi)有一(yi)定的(de)差別(bie)。

電(dian)(dian)(dian)(dian)(dian)(dian)動車(che)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量的(de)(de)大小取決于(yu)參與電(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學(xue)反(fan)(fan)應(ying)的(de)(de)活性(xing)物(wu)質(zhi)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)質(zhi)量的(de)(de)多(duo)(duo)少。極板的(de)(de)制造工藝、幾何形狀大小及蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使用(yong)時(shi)的(de)(de)氣溫(wen)(wen)對測(ce)得的(de)(de)實際(ji)容量也(ye)有影響。極板片(pian)數越(yue)(yue)(yue)多(duo)(duo)，相對面積越(yue)(yue)(yue)大，參與化(hua)學(xue)反(fan)(fan)應(ying)的(de)(de)活性(xing)物(wu)質(zhi)越(yue)(yue)(yue)多(duo)(duo)，電(dian)(dian)(dian)(dian)(dian)(dian)動車(che)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)就(jiu)越(yue)(yue)(yue)大；蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使用(yong)時(shi)的(de)(de)氣溫(wen)(wen)越(yue)(yue)(yue)高，電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)液向極板的(de)(de)滲透能(neng)力(li)超強，參與化(hua)學(xue)反(fan)(fan)應(ying)的(de)(de)活性(xing)物(wu)質(zhi)的(de)(de)深(shen)度就(jiu)越(yue)(yue)(yue)深(shen)，電(dian)(dian)(dian)(dian)(dian)(dian)動車(che)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)就(jiu)越(yue)(yue)(yue)大。

電(dian)動車上常用的閥控鉛酸電(dian)池主要有(you)6-DZM-10及6-DZM-20兩種標準規(gui)格，這里的6是指電(dian)池內部(bu)由6個集群串聯組成，前者(zhe)2Hr容量(liang)為(wei)10安時（Ah），后者(zhe)2Hr容量(liang)為(wei)20Ah，有(you)的廠家也用12V10Ah/2Hr和(he)12V20Ah/2Hr標識。為(wei)適應更多的設計，在調整電(dian)池極板形狀、厚度(du)、數量(liang)和(he)電(dian)解液濃度(du)、活性物質用量(liang)比例(li)等工藝后，也有(you)諸如6-DZM-7、6-DZM-12、6-DZM-17、6-DZM-18、6-DZM-24等型號。

1、“mAh”是電(dian)池(chi)容量(liang)的單位(wei)，中文名(ming)稱為毫安時(shi)(在衡量(liang)大容量(liang)電(dian)池(chi)如鉛蓄(xu)電(dian)池(chi)時(shi)，為了方便起見，一(yi)般用“Ah”來表示，中文名(ming)是安時(shi)）。

1mAh=0.001安培*3600秒(miao)=3.6安培秒(miao)=3.6庫侖；

2、庫(ku)(ku)侖(lun)是電量單(dan)(dan)位(wei)，庫(ku)(ku)侖(lun)不是國際單(dan)(dan)位(wei)制(zhi)基本單(dan)(dan)位(wei)，而是國際單(dan)(dan)位(wei)特種出單(dan)(dan)位(wei)。1庫(ku)(ku)侖(lun)=1安培·秒。

1A電流在1s內輸運的電量，即(ji)1C=1A·s。

3、功率電功率計算公式：P=UI。P的單位是瓦特W；在純電阻電路中，根據歐姆定律U=IR代入P=UI中還可以得到：P=IIR=(UU)/R；

一、最直接算法：

1、先得到用電設備(bei)的電流

2、再將(jiang)電池容量除以用電設備的電流結果就是可(ke)使用的時長

例如：

一個3000mAH，額定電(dian)壓(ya)5V的(de)電(dian)池給一個功耗2.5W，電(dian)壓(ya)5V的(de)用電(dian)設備供電(dian)，它理論的(de)使用時長為：

I=P/U=>2.5w/5v=>0.5A=>500MA

3000mAh,就是(shi)3000MA電流(liu)可以放(fang)電一小時，

3000/500=6小時

二、通過(guo)電荷量庫侖(lun)算法

C=IS=>3A*3600s=>10800c庫侖（電荷(he)量(liang)）

10800c*5v=54000w電能(neng)

54000w/2.5w=21600/3600s=6h

UPS后(hou)備(bei)時間(jian)的算法(fa)2010-03-2515:20

UPS電(dian)池放電(dian)時間(jian)計算方(fang)法

1）計算(suan)蓄電池的最大放電電流值(zhi)：

I最大=Pcosф/（ηE臨界N）注：P→UPS電源的(de)標稱輸出功率

cosф→UPS電源的(de)輸出功率因數（UPS一般為0.8）

η→EPS逆變(bian)器的效率(lv)，一般為0.88~0.94（實際計算中可以取0.9）

E臨界→蓄電(dian)池(chi)組的(de)臨界放電(dian)電(dian)壓(ya)（12V電(dian)池(chi)約(yue)為10.5V，2V電(dian)池(chi)約(yue)為1.7V）

N→每組電池的數量

2）根據(ju)所選的(de)蓄電池組的(de)后(hou)備時間，查出所需的(de)電池組的(de)放電速率值C，然后(hou)根據(ju)：

電池組(zu)的標稱容量=I最大/C時(shi)間與(yu)放電速率C

15分(fen)鐘30分(fen)鐘60分(fen)鐘90分(fen)鐘120分(fen)鐘180分(fen)鐘1.98C0.92C0.61C0.5C0.42C0.29C

3）例如400KVA延(yan)時15分鐘

電池的最大放電電流1058A=標稱功率400000VA×0.8÷（0.9效率32節10.5V每節(jie)電池放(fang)電電壓）

電池(chi)組的(de)標稱(cheng)容量=1058A÷1.98C=534.3AH

電(dian)池組的總容量=534.3AH×32節(jie)×12V=205171.2AH因此配置節(jie)12V150AH32節(jie)4

以(yi)上就是關(guan)于鉛酸(suan)(suan)蓄電(dian)池如何計算容量和(he)放電(dian)量大(da)小的(de)方法，相信很多(duo)朋友看(kan)到這里，對(dui)鉛酸(suan)(suan)蓄電(dian)池有了(le)(le)更深的(de)了(le)(le)解了(le)(le)。
