【蓄電(dian)池容量(liang)】蓄電(dian)池容量(liang)計算公式(shi) 蓄電(dian)池容量(liang)測(ce)試新(xin)技術介紹

蓄電池容量計算公式

容量=放電(dian)電(dian)流×放電(dian)時間

蓄電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)容(rong)量(liang)與放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流大小及電(dian)(dian)(dian)(dian)(dian)解液的(de)(de)(de)(de)溫度有關，因此標(biao)稱容(rong)量(liang)是在一(yi)定的(de)(de)(de)(de)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流、一(yi)定的(de)(de)(de)(de)終(zhong)止電(dian)(dian)(dian)(dian)(dian)壓和(he)一(yi)定的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)解液溫度下(xia)取得的(de)(de)(de)(de)，標(biao)容(rong)量(liang)有兩(liang)種。

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(xia)，以20小時率放電(dian)的(de)電(dian)流（相當于額定容量(liang)的(de)1/20）連續放電至單(dan)體1.75V時輸出的電量(liang)。

起動容量

常溫起動容量：指電解液溫度為30 ℃時，以5min率放電(dian)電(dian)流（3倍額定容(rong)量電(dian)流）連續放電(dian)至規定的終止電(dian)壓（6V蓄電(dian)池為4.5V，12V蓄電池為9V）時，所輸出的電量，其放電持續時間應在(zai)5min以上

低溫起動容量：電解液溫度為-18℃時，以(yi)3倍額定容量的電(dian)流連續放電(dian)至(zhi)規定終(zhong)止(zhi)電(dian)壓（12V蓄電池為(wei)6V，6V蓄電(dian)池為(wei)3V）時(shi)(shi)所放出的電(dian)(dian)量，其放電(dian)(dian)持續(xu)時(shi)(shi)間應在(zai)2.5min以(yi)上(shang)。

蓄電池容量測試新技術介紹

通訊后備(bei)蓄(xu)電(dian)(dian)池(chi)(chi)質量(liang)是通訊網絡供電(dian)(dian)不(bu)中斷的重要保障，是整個通訊電(dian)(dian)源設備(bei)供電(dian)(dian)保障，保證通訊網絡正常運行的最后一道(dao)防線。根據蓄(xu)電(dian)(dian)池(chi)(chi)特性(xing)和(he)維護要求(qiu)，蓄(xu)電(dian)(dian)池(chi)(chi)放電(dian)(dian)容量(liang)測(ce)試工作是必(bi)不(bu)可少的。

隨著通(tong)訊網絡規模的(de)(de)迅猛發展，現網電源維護(hu)專業技術職(zhi)員相對較少(shao)，當(dang)前(qian)電池(chi)(chi)放電容(rong)量(liang)測試(shi)方(fang)式存(cun)在安全隱患，操縱復雜，測試(shi)工作(zuo)量(liang)大的(de)(de)題目(mu)，致(zhi)使維護(hu)規程(cheng)要(yao)求的(de)(de)電池(chi)(chi)放電測試(shi)工作(zuo)得(de)不到(dao)(dao)有效落(luo)實，落(luo)后電池(chi)(chi)不能(neng)及時(shi)得(de)到(dao)(dao)預(yu)警和維護(hu)，在用電池(chi)(chi)往(wang)往(wang)被提前(qian)報廢，造成資源浪費。

團體公(gong)司(si)、福建(jian)公(gong)司(si)針對電(dian)(dian)池放(fang)電(dian)(dian)技術聯(lian)合進行(xing)研究，導進了(le)創新性的全(quan)在線電(dian)(dian)池放(fang)電(dian)(dian)技術，全(quan)面解決了(le)幾十年來(lai)原電(dian)(dian)池放(fang)電(dian)(dian)技術中存在的安全(quan)隱患題目(mu)。

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)一組(zu)電(dian)(dian)(dian)(dian)(dian)池脫(tuo)離系統后，一旦市電(dian)(dian)(dian)(dian)(dian)中(zhong)斷，系統備用電(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間(jian)明顯縮短，何況(kuang)此(ci)時(shi)(shi)尚不清楚另一組(zu)在線電(dian)(dian)(dian)(dian)(dian)池是否存在質量題(ti)目，此(ci)放電(dian)(dian)(dian)(dian)(dian)方(fang)式事(shi)故風險性高。如要用此(ci)方(fang)式放電(dian)(dian)(dian)(dian)(dian)，建議提前啟用發動(dong)機組(zu)，并(bing)確(que)保發電(dian)(dian)(dian)(dian)(dian)機組(zu)、開關(guan)電(dian)(dian)(dian)(dian)(dian)源等設備能正(zheng)常運行，保證安(an)全；

（2）離(li)(li)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)結束后(hou)的電(dian)(dian)(dian)池(chi)組(zu)與(yu)在線(xian)(xian)電(dian)(dian)(dian)池(chi)組(zu)間(jian)存(cun)在較大(da)電(dian)(dian)(dian)壓(ya)差，若操(cao)縱不(bu)當將引起(qi)開關電(dian)(dian)(dian)源和在線(xian)(xian)電(dian)(dian)(dian)池(chi)組(zu)對離(li)(li)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)后(hou)的電(dian)(dian)(dian)池(chi)組(zu)進行(xing)大(da)電(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)，產(chan)生(sheng)巨大(da)火花(hua)，易(yi)發生(sheng)安(an)全事故。用此(ci)方式放(fang)(fang)電(dian)(dian)(dian)，需要(yao)配(pei)備(bei)一臺整(zheng)組(zu)智能充(chong)電(dian)(dian)(dian)機，對該(gai)離(li)(li)線(xian)(xian)電(dian)(dian)(dian)池(chi)組(zu)先充(chong)電(dian)(dian)(dian)恢復后(hou)再并聯回系統(tong)，以(yi)解決打(da)火花(hua)題目，這樣將使(shi)系統(tong)更(geng)長時間(jian)處于(yu)單組(zu)供電(dian)(dian)(dian)狀態，事故風險高。另通過調整(zheng)整(zheng)流器(qi)輸出與(yu)被(bei)放(fang)(fang)電(dian)(dian)(dian)的電(dian)(dian)(dian)池(chi)組(zu)電(dian)(dian)(dian)壓(ya)相等(deng)后(hou)進行(xing)恢復連接。上述操(cao)縱一定要(yao)謹(jin)慎(shen)操(cao)縱；

（3）此放電(dian)(dian)(dian)方式操縱時(shi)既要脫(tuo)(tuo)離電(dian)(dian)(dian)池組的正極，又要脫(tuo)(tuo)離電(dian)(dian)(dian)池組的負極，尤(you)其是(shi)脫(tuo)(tuo)離電(dian)(dian)(dian)池組負極時(shi)需要特別小心，操縱不(bu)當引起負極短路，將造成系(xi)統(tong)供(gong)電(dian)(dian)(dian)中斷，導致通訊事故的發生；

（4）此方式是將電(dian)(dian)池通(tong)過(guo)假(jia)負載以熱量形式消耗，浪費電(dian)(dian)能，影響機房設備(bei)運行環境，需(xu)要(yao)維護職員時刻守(shou)護以免(mian)高溫(wen)引(yin)發事故。

1.2在線評估式放電法技術分析

（1）調整整流器(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓至(zhi)(zhi)保(bao)(bao)護(hu)低壓值(zhi)（如(ru)(ru)46V），使所(suo)有(you)后備(bei)(bei)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)直接(jie)對(dui)實際(ji)負荷進行放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)至(zhi)(zhi)整流器(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓保(bao)(bao)護(hu)設(she)置值(zhi)。由于現網系(xi)統設(she)備(bei)(bei)盡(jin)大(da)多數電(dian)(dian)(dian)(dian)(dian)池(chi)配置后備(bei)(bei)供電(dian)(dian)(dian)(dian)(dian)時間為1～4h，放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流大(da)，應(ying)考(kao)慮電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)至(zhi)(zhi)設(she)備(bei)(bei)供電(dian)(dian)(dian)(dian)(dian)回路壓降(jiang)及設(she)備(bei)(bei)低壓工(gong)作門限，以及保(bao)(bao)證系(xi)統供電(dian)(dian)(dian)(dian)(dian)安全，在(zai)(zai)線(xian)評估(gu)式放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)其調整整流器(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓不答應(ying)過低（如(ru)(ru)46V），放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)深度有(you)限，對(dui)實際(ji)負載(zai)的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時間把握比較困難(nan)，評估(gu)電(dian)(dian)(dian)(dian)(dian)池(chi)容量難(nan)以正確(que)，對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)性能測(ce)試有(you)不確(que)定(ding)因素存在(zai)(zai)，從而對(dui)保(bao)(bao)持(chi)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)活(huo)性這一放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)試目的(de)難(nan)以達到維護(hu)預期工(gong)作效(xiao)果；

（2）假如兩組(zu)電(dian)池都有失容或欠容、落(luo)后等質量題目，當其放(fang)電(dian)至整流器輸出保護(hu)值(zhi)的時間，不易被維(wei)護(hu)職員及時發現，此(ci)時可能后備電(dian)池容量所剩(sheng)無幾，存在(zai)高(gao)風險。在(zai)此(ci)情況(kuang)下，此(ci)放(fang)電(dian)方(fang)式(shi)比離線放(fang)電(dian)方(fang)式(shi)安全性更低；

（3）由(you)于(yu)放(fang)(fang)電(dian)(dian)深(shen)度有限，對(dui)保(bao)持電(dian)(dian)池(chi)組(zu)的(de)活性這一(yi)放(fang)(fang)電(dian)(dian)測試(shi)的(de)目的(de)無法(fa)達(da)到，更為關鍵的(de)是在全容量放(fang)(fang)電(dian)(dian)的(de)實(shi)踐中我們經常發現有些電(dian)(dian)池(chi)組(zu)在放(fang)(fang)電(dian)(dian)前期表(biao)現正常，但到中后期，有些落后電(dian)(dian)池(chi)才(cai)開始逐步暴露出來。這一(yi)部分(fen)落后單體，于(yu)此(ci)放(fang)(fang)電(dian)(dian)方式的(de)深(shen)度不夠而(er)沒(mei)有被發現。所以我們稱此(ci)放(fang)(fang)電(dian)(dian)方式為在線評估(gu)式，它只能大致評估(gu)電(dian)(dian)池(chi)組(zu)性能，或檢測此(ci)電(dian)(dian)池(chi)組(zu)可以放(fang)(fang)電(dian)(dian)至此(ci)保(bao)護電(dian)(dian)壓的(de)時(shi)間(jian)是非，而(er)無法(fa)進(jin)一(yi)步檢查除此(ci)時(shi)間(jian)外究竟(jing)還能放(fang)(fang)電(dian)(dian)多長時(shi)間(jian)；

（4）組間電(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)不均衡。各(ge)組電(dian)(dian)(dian)池(chi)將根據自身情況(kuang)自然分(fen)攤系統的負荷(he)電(dian)(dian)(dian)流(liu)(liu)來放(fang)電(dian)(dian)(dian)，落后電(dian)(dian)(dian)池(chi)組，內阻(zu)大，分(fen)攤電(dian)(dian)(dian)流(liu)(liu)小，而(er)健康電(dian)(dian)(dian)池(chi)組，內阻(zu)低(di)，分(fen)攤電(dian)(dian)(dian)流(liu)(liu)大，造成(cheng)某些落后電(dian)(dian)(dian)池(chi)因放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)不夠大而(er)無法暴露出(chu)來的現象，達不到我(wo)們進行(xing)放(fang)電(dian)(dian)(dian)性能(neng)質量檢測目的。

綜(zong)上所(suo)述，在(zai)(zai)中(zhong)心(xin)機房蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)必須定期進(jin)(jin)行(xing)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)的(de)(de)(de)需求下，目前(qian)兩(liang)種容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)方(fang)(fang)法，各有特點又(you)各有弊端(duan)，離(li)線(xian)放(fang)電(dian)(dian)(dian)(dian)(dian)方(fang)(fang)法固(gu)然(ran)可以達(da)(da)到(dao)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)的(de)(de)(de)目的(de)(de)(de)，但(dan)是(shi)工作(zuo)(zuo)量(liang)(liang)(liang)太大，系(xi)(xi)統安全(quan)性(xing)偏低，而在(zai)(zai)線(xian)評估式放(fang)電(dian)(dian)(dian)(dian)(dian)方(fang)(fang)法固(gu)然(ran)工作(zuo)(zuo)量(liang)(liang)(liang)比較小，但(dan)是(shi)系(xi)(xi)統安全(quan)性(xing)低，達(da)(da)不到(dao)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)的(de)(de)(de)目的(de)(de)(de)，潛(qian)伏的(de)(de)(de)安全(quan)隱患大。因此，當前(qian)的(de)(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)方(fang)(fang)法必須改革，現將引進(jin)(jin)一種全(quan)新的(de)(de)(de)、科學的(de)(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)技術——全(quan)在(zai)(zai)線(xian)放(fang)電(dian)(dian)(dian)(dian)(dian)技術，以使電(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)(shi)達(da)(da)到(dao)預期維(wei)護質(zhi)量(liang)(liang)(liang)檢測(ce)(ce)(ce)效(xiao)果，電(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)維(wei)護操縱簡便安全(quan)，進(jin)(jin)步(bu)了維(wei)護工作(zuo)(zuo)效(xiao)率易得到(dao)有效(xiao)的(de)(de)(de)落實。

2.2在線放電“無縫連接”技術

為確保電池放(fang)電測試的安全(quan)性，電池組(zu)全(quan)在(zai)線(xian)放(fang)電設備在(zai)串(chuan)聯接進電池組(zu)正極時要求以(yi)無縫連接方式，如圖5所示。

圖5在線放(fang)電容量測試接線圖

電池組在線放電測試無縫連(lian)(lian)接(jie)操縱(zong)，“設備”接(jie)進應遵(zun)守“先接(jie)三，后拆一(yi)”，即為先接(jie)電源(yuan)線L1、L2、L3，后拆原(yuan)電源(yuan)連(lian)(lian)接(jie)線L5；“設備”成測試退出服(fu)務(wu)，應遵(zun)守“先接(jie)一(yi)，后拆三”的原(yuan)則，即為先接(jie)原(yuan)電源(yuan)連(lian)(lian)接(jie)線L5，后拆電源(yuan)線L1、L2、L3。

（1）全在線放電(dian)方式能夠達到深度放電(dian)保持電(dian)池活性及檢測落后電(dian)池的(de)(de)放電(dian)測試目(mu)的(de)(de)，充分把握電(dian)池組剩余容量和后備供電(dian)時間；

（2）在放電(dian)(dian)過程中最大(da)限度地保證電(dian)(dian)池組備用電(dian)(dian)能(neng)，最大(da)限度地降低了容量測(ce)試造成系統癱瘓(huan)的風(feng)險；

（3）全在線放(fang)電(dian)方式能(neng)夠實現各組(zu)(zu)電(dian)池(chi)以相同電(dian)流進行(xing)分組(zu)(zu)放(fang)電(dian)，任何落(luo)后單體電(dian)池(chi)都能(neng)暴露出來，克服了(le)在線評估式放(fang)電(dian)的局限性(xing)；

（4）全(quan)在線(xian)放(fang)(fang)電(dian)設備一旦(dan)串聯接(jie)進電(dian)池組的(de)正極(ji)，設定相關放(fang)(fang)電(dian)參數后(hou)，所有放(fang)(fang)電(dian)充電(dian)工作自(zi)動完(wan)成，維護(hu)職員可以進行其它工作，降低工作強度，進步工作效(xiao)率。
