蓄電池容量計算公式

容量=放(fang)電電流(liu)×放(fang)電時間

蓄電(dian)(dian)池的(de)(de)(de)容(rong)量與(yu)放(fang)電(dian)(dian)電(dian)(dian)流(liu)大小及電(dian)(dian)解液的(de)(de)(de)溫度(du)有關，因(yin)此標稱容(rong)量是在一定(ding)的(de)(de)(de)放(fang)電(dian)(dian)電(dian)(dian)流(liu)、一定(ding)的(de)(de)(de)終止電(dian)(dian)壓(ya)和(he)一定(ding)的(de)(de)(de)電(dian)(dian)解液溫度(du)下(xia)取得的(de)(de)(de)，標容(rong)量有兩種(zhong)。

額定容量

額定容量是指完全充足電的蓄電池在電解液平均溫度30 ℃的情況下，以20小(xiao)時(shi)率放電的(de)電流（相當于(yu)額(e)定容量的(de)1/20）連續放電至(zhi)單體1.75V時(shi)輸(shu)出(chu)的(de)電量。

起動容量

常溫起動容量：指電解液溫度為30 ℃時，以5min率(lv)放電電流（3倍額定容(rong)量電(dian)流）連續(xu)放電(dian)至規定的(de)終止電(dian)壓（6V蓄電池為4.5V，12V蓄(xu)電池為(wei)9V）時(shi)，所輸(shu)出的(de)電(dian)量，其放電(dian)持續(xu)時(shi)間(jian)應在5min以(yi)上

低溫起動容量：電解液溫度為-18℃時，以3倍額定容量的電流連續放(fang)電至規定終止(zhi)電壓(ya)（12V蓄(xu)電池為6V，6V蓄(xu)電池(chi)為3V）時所放出的電量(liang)，其放電持續(xu)時間(jian)應在2.5min以(yi)上。

蓄電池容量測試新技術介紹

通訊后備蓄電池質量(liang)是(shi)通訊網絡供(gong)電不中斷的重要保(bao)障，是(shi)整個通訊電源設備供(gong)電保(bao)障，保(bao)證通訊網絡正常運(yun)行的最后一道防(fang)線。根據(ju)蓄電池特性和(he)維護要求(qiu)，蓄電池放電容量(liang)測試(shi)工作是(shi)必不可少的。

隨著通訊網(wang)絡規模的(de)迅猛發展(zhan)，現網(wang)電源維(wei)護專業技術職員相(xiang)對較少(shao)，當前(qian)電池(chi)放電容量(liang)測(ce)試(shi)(shi)(shi)方式存在(zai)安全(quan)隱患，操縱(zong)復(fu)雜，測(ce)試(shi)(shi)(shi)工作(zuo)量(liang)大(da)的(de)題(ti)目(mu)，致使維(wei)護規程(cheng)要求的(de)電池(chi)放電測(ce)試(shi)(shi)(shi)工作(zuo)得(de)不到有(you)效(xiao)落實，落后電池(chi)不能及時得(de)到預警和(he)維(wei)護，在(zai)用電池(chi)往往被提前(qian)報廢(fei)，造(zao)成(cheng)資(zi)源浪(lang)費。

團體公司、福建公司針對電(dian)池(chi)(chi)放(fang)電(dian)技術(shu)(shu)聯合進(jin)行研究，導進(jin)了(le)(le)創新性的全(quan)在(zai)線(xian)電(dian)池(chi)(chi)放(fang)電(dian)技術(shu)(shu)，全(quan)面解決(jue)了(le)(le)幾十年來原電(dian)池(chi)(chi)放(fang)電(dian)技術(shu)(shu)中存在(zai)的安全(quan)隱患題目。

1、當前電池放電技術分析

1.1離線式放電法技術分析

（1）將其中(zhong)一(yi)組(zu)(zu)電池脫離系統(tong)后，一(yi)旦市(shi)電中(zhong)斷，系統(tong)備(bei)用電池供(gong)電時間(jian)明顯(xian)縮(suo)短，何況此時尚不清楚另一(yi)組(zu)(zu)在線電池是否存(cun)在質量(liang)題(ti)目，此放電方(fang)(fang)式事(shi)故(gu)風險性高。如要用此方(fang)(fang)式放電，建議提前啟用發動機(ji)組(zu)(zu)，并確保發電機(ji)組(zu)(zu)、開關(guan)電源等設(she)備(bei)能(neng)正常運行，保證安(an)全；

（2）離(li)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)結束后(hou)(hou)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)與在(zai)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)間存在(zai)較大(da)電(dian)(dian)(dian)(dian)(dian)壓差，若操(cao)縱(zong)不當將引起開(kai)關電(dian)(dian)(dian)(dian)(dian)源(yuan)和(he)在(zai)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)對(dui)離(li)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)后(hou)(hou)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)進行大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)(dian)(dian)，產(chan)生巨大(da)火花，易發生安全事故(gu)。用(yong)此方(fang)式放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，需要(yao)配備一臺整(zheng)(zheng)組(zu)(zu)智能充電(dian)(dian)(dian)(dian)(dian)機，對(dui)該離(li)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)先充電(dian)(dian)(dian)(dian)(dian)恢復后(hou)(hou)再并聯(lian)回(hui)系統，以(yi)解決打火花題目，這樣(yang)將使系統更長時間處于單組(zu)(zu)供電(dian)(dian)(dian)(dian)(dian)狀(zhuang)態，事故(gu)風險高。另通過調整(zheng)(zheng)整(zheng)(zheng)流(liu)器輸出與被放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)電(dian)(dian)(dian)(dian)(dian)壓相等后(hou)(hou)進行恢復連接。上述操(cao)縱(zong)一定要(yao)謹慎操(cao)縱(zong)；

（3）此放(fang)電(dian)方式操縱(zong)時(shi)既要(yao)(yao)脫離(li)電(dian)池(chi)組(zu)的(de)(de)正極(ji)(ji)(ji)，又要(yao)(yao)脫離(li)電(dian)池(chi)組(zu)的(de)(de)負極(ji)(ji)(ji)，尤其是(shi)脫離(li)電(dian)池(chi)組(zu)負極(ji)(ji)(ji)時(shi)需要(yao)(yao)特別小(xiao)心，操縱(zong)不當(dang)引(yin)起負極(ji)(ji)(ji)短路，將(jiang)造成系統供電(dian)中斷(duan)，導致通(tong)訊事故(gu)的(de)(de)發生；

（4）此方式(shi)是(shi)將電(dian)(dian)池通過假負載以熱量形(xing)式(shi)消耗，浪費電(dian)(dian)能(neng)，影響機房設備運行環境，需要維(wei)護職(zhi)員時刻守護以免高溫引發事故。

1.2在線評估式放電法技術分析

（1）調整整流(liu)器輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓至(zhi)(zhi)保護(hu)(hu)低壓值（如46V），使所(suo)有后備(bei)(bei)(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)直接對(dui)(dui)實際負荷進行放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)至(zhi)(zhi)整流(liu)器輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓保護(hu)(hu)設(she)置值。由于現網系統設(she)備(bei)(bei)(bei)盡大(da)多(duo)數電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池配置后備(bei)(bei)(bei)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間為1～4h，放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大(da)，應考慮電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)至(zhi)(zhi)設(she)備(bei)(bei)(bei)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)回路壓降及設(she)備(bei)(bei)(bei)低壓工(gong)作門限(xian)，以(yi)及保證系統供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)安(an)全，在(zai)(zai)線評(ping)估(gu)式放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)其調整整流(liu)器輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓不答應過低（如46V），放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)深度有限(xian)，對(dui)(dui)實際負載(zai)的放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間把握比較困(kun)難，評(ping)估(gu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池容量難以(yi)正確，對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池性(xing)能測試有不確定(ding)因素存在(zai)(zai)，從而對(dui)(dui)保持電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)活性(xing)這一放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測試目的難以(yi)達到維護(hu)(hu)預期工(gong)作效果(guo)；

（2）假如兩組電池(chi)都有(you)失容或欠容、落后等質量(liang)題目，當(dang)其放(fang)電至整流(liu)器(qi)輸出保(bao)護值的時(shi)間，不易被維護職員(yuan)及時(shi)發現，此(ci)(ci)時(shi)可能后備電池(chi)容量(liang)所(suo)剩無幾，存在(zai)(zai)高風險(xian)。在(zai)(zai)此(ci)(ci)情況下，此(ci)(ci)放(fang)電方(fang)式比離線放(fang)電方(fang)式安全性更(geng)低；

（3）由于(yu)放電(dian)(dian)深度有限，對保持電(dian)(dian)池(chi)(chi)組(zu)的(de)(de)活性這一(yi)放電(dian)(dian)測(ce)試(shi)的(de)(de)目的(de)(de)無法達到，更為(wei)關鍵的(de)(de)是在全容(rong)量放電(dian)(dian)的(de)(de)實踐中我(wo)們經常發(fa)現(xian)(xian)有些電(dian)(dian)池(chi)(chi)組(zu)在放電(dian)(dian)前期(qi)表現(xian)(xian)正常，但到中后(hou)(hou)期(qi)，有些落后(hou)(hou)電(dian)(dian)池(chi)(chi)才開始逐(zhu)步(bu)暴露(lu)出來。這一(yi)部分落后(hou)(hou)單體，于(yu)此(ci)放電(dian)(dian)方(fang)(fang)式(shi)的(de)(de)深度不夠而沒有被(bei)發(fa)現(xian)(xian)。所以我(wo)們稱此(ci)放電(dian)(dian)方(fang)(fang)式(shi)為(wei)在線(xian)評(ping)估(gu)式(shi)，它只能大致評(ping)估(gu)電(dian)(dian)池(chi)(chi)組(zu)性能，或檢(jian)測(ce)此(ci)電(dian)(dian)池(chi)(chi)組(zu)可以放電(dian)(dian)至(zhi)此(ci)保護(hu)電(dian)(dian)壓(ya)的(de)(de)時間(jian)是非，而無法進一(yi)步(bu)檢(jian)查除此(ci)時間(jian)外究竟還能放電(dian)(dian)多長時間(jian)；

（4）組(zu)(zu)(zu)間電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)不均(jun)衡。各組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)將根據自身(shen)情況自然(ran)分(fen)攤(tan)系統(tong)的負(fu)荷電(dian)(dian)(dian)(dian)(dian)流(liu)來(lai)放電(dian)(dian)(dian)(dian)(dian)，落后(hou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)(zu)(zu)，內阻(zu)大(da)(da)，分(fen)攤(tan)電(dian)(dian)(dian)(dian)(dian)流(liu)小，而健康電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)(zu)(zu)，內阻(zu)低，分(fen)攤(tan)電(dian)(dian)(dian)(dian)(dian)流(liu)大(da)(da)，造成某些落后(hou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)因放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)不夠大(da)(da)而無法暴露出來(lai)的現象(xiang)，達(da)不到我們進(jin)行(xing)放電(dian)(dian)(dian)(dian)(dian)性能(neng)質(zhi)量(liang)檢測目的。

綜上所述(shu)，在中心機房(fang)蓄電(dian)(dian)池必須定期(qi)進行容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)需求下(xia)，目(mu)前(qian)(qian)兩(liang)種容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)法(fa)，各有特(te)點(dian)又各有弊端，離線放電(dian)(dian)方(fang)法(fa)固(gu)然可以達(da)到(dao)(dao)蓄電(dian)(dian)池容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)目(mu)的(de)(de)，但是工(gong)作量(liang)(liang)太大，系(xi)統安(an)全性偏低，而(er)在線評估式放電(dian)(dian)方(fang)法(fa)固(gu)然工(gong)作量(liang)(liang)比較(jiao)小(xiao)，但是系(xi)統安(an)全性低，達(da)不到(dao)(dao)蓄電(dian)(dian)池容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)的(de)(de)目(mu)的(de)(de)，潛伏的(de)(de)安(an)全隱患大。因此，當前(qian)(qian)的(de)(de)蓄電(dian)(dian)池容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)法(fa)必須改革，現(xian)將引進一種全新的(de)(de)、科學的(de)(de)容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)技術——全在線放電(dian)(dian)技術，以使電(dian)(dian)池放電(dian)(dian)容(rong)(rong)量(liang)(liang)測(ce)(ce)(ce)試(shi)達(da)到(dao)(dao)預期(qi)維(wei)護質(zhi)量(liang)(liang)檢測(ce)(ce)(ce)效(xiao)(xiao)果，電(dian)(dian)池放電(dian)(dian)維(wei)護操(cao)縱簡便安(an)全，進步了維(wei)護工(gong)作效(xiao)(xiao)率易(yi)得到(dao)(dao)有效(xiao)(xiao)的(de)(de)落實。

2、全在線放電技術分析

2.1在線放電結束后，自動完成在線充電恢復等電位連接

被(bei)測(ce)電(dian)(dian)(dian)池組(zu)放(fang)(fang)電(dian)(dian)(dian)測(ce)試結束后，電(dian)(dian)(dian)池組(zu)全(quan)在線放(fang)(fang)電(dian)(dian)(dian)設備自(zi)動進(jin)(jin)進(jin)(jin)充(chong)(chong)電(dian)(dian)(dian)程序(xu)，引(yin)導在線開關(guan)電(dian)(dian)(dian)源的(de)(de)整流(liu)輸(shu)出，經過全(quan)在線放(fang)(fang)電(dian)(dian)(dian)測(ce)試設備的(de)(de)充(chong)(chong)電(dian)(dian)(dian)、等電(dian)(dian)(dian)位控制(zhi)保護電(dian)(dian)(dian)路自(zi)動對被(bei)測(ce)放(fang)(fang)電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)池組(zu)進(jin)(jin)行限流(liu)充(chong)(chong)電(dian)(dian)(dian)，自(zi)動完成(cheng)在線等電(dian)(dian)(dian)位連(lian)接(jie)，根據(ju)全(quan)在線放(fang)(fang)電(dian)(dian)(dian)測(ce)試設備系統提示操縱要求(qiu)，恢復系統的(de)(de)正(zheng)常連(lian)接(jie)后，全(quan)在線放(fang)(fang)電(dian)(dian)(dian)測(ce)試設備退出服務(wu)，完成(cheng)結束蓄(xu)電(dian)(dian)(dian)池組(zu)全(quan)在線放(fang)(fang)電(dian)(dian)(dian)、充(chong)(chong)電(dian)(dian)(dian)恢復等電(dian)(dian)(dian)位正(zheng)常連(lian)接(jie)全(quan)過程。另(ling)一組(zu)電(dian)(dian)(dian)池以同樣(yang)的(de)(de)方(fang)式進(jin)(jin)行在線放(fang)(fang)電(dian)(dian)(dian)容量測(ce)試。如(ru)圖(tu)4所示。

3.2與在線評估式放電技術對比分析

（1）全在線放(fang)電(dian)(dian)(dian)方式能夠達到深度放(fang)電(dian)(dian)(dian)保持電(dian)(dian)(dian)池(chi)活性及檢測落后(hou)電(dian)(dian)(dian)池(chi)的放(fang)電(dian)(dian)(dian)測試(shi)目的，充分把握電(dian)(dian)(dian)池(chi)組剩(sheng)余容量和后(hou)備供電(dian)(dian)(dian)時間(jian)；
