【蓄電池(chi)容量(liang)】蓄電池(chi)容量(liang)計算公式(shi) 蓄電池(chi)容量(liang)測試(shi)新技術介紹

蓄電池容量計算公式

容量=放電電流×放電時間

蓄(xu)電(dian)池的容量與放電(dian)電(dian)流(liu)大(da)小及電(dian)解液(ye)的溫(wen)度有(you)關，因此標稱容量是在一(yi)定的放電(dian)電(dian)流(liu)、一(yi)定的終止電(dian)壓和一(yi)定的電(dian)解液(ye)溫(wen)度下取得的，標容量有(you)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(xia)，以20小時率放電(dian)的電(dian)流（相當(dang)于額定容(rong)量的1/20）連(lian)續放(fang)電至單體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率放電電流（3倍額定(ding)容量電流）連(lian)續放電至(zhi)規定(ding)的終止電壓（6V蓄(xu)電池(chi)為4.5V，12V蓄(xu)電池為9V）時，所輸出的電量，其放(fang)電持續時間應在5min以上

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(lian)續放電至規(gui)定終止電壓（12V蓄電(dian)池(chi)為6V，6V蓄電池為3V）時所(suo)放出的(de)電量，其放電持續時間應在2.5min以上(shang)。

蓄電池容量測試新技術介紹

通(tong)訊(xun)(xun)(xun)(xun)后備蓄(xu)電(dian)(dian)(dian)池(chi)質量是(shi)(shi)通(tong)訊(xun)(xun)(xun)(xun)網(wang)絡供(gong)電(dian)(dian)(dian)不中斷(duan)的(de)(de)重要(yao)保(bao)障，是(shi)(shi)整個通(tong)訊(xun)(xun)(xun)(xun)電(dian)(dian)(dian)源(yuan)設備供(gong)電(dian)(dian)(dian)保(bao)障，保(bao)證通(tong)訊(xun)(xun)(xun)(xun)網(wang)絡正(zheng)常(chang)運行的(de)(de)最后一道防(fang)線。根據蓄(xu)電(dian)(dian)(dian)池(chi)特性和維護要(yao)求，蓄(xu)電(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)容(rong)量測試工作是(shi)(shi)必不可少的(de)(de)。

隨著通訊網(wang)絡規(gui)模的迅猛發展，現網(wang)電(dian)(dian)源維護(hu)專業技術(shu)職員相(xiang)對(dui)較少，當前電(dian)(dian)池放電(dian)(dian)容量測(ce)(ce)試(shi)方(fang)式存在安全隱患，操(cao)縱復(fu)雜(za)，測(ce)(ce)試(shi)工(gong)作量大的題目(mu)，致使維護(hu)規(gui)程要(yao)求(qiu)的電(dian)(dian)池放電(dian)(dian)測(ce)(ce)試(shi)工(gong)作得不到有(you)效(xiao)落實，落后電(dian)(dian)池不能及(ji)時(shi)得到預警和維護(hu)，在用電(dian)(dian)池往(wang)往(wang)被提(ti)前報廢，造成資源浪費。

團體公司、福建(jian)公司針對電池放電技術聯(lian)合(he)進行研究，導進了(le)創新性的全(quan)在(zai)線電池放電技術，全(quan)面解決了(le)幾十年來原電池放電技術中存在(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(qi)中一組(zu)(zu)(zu)電(dian)(dian)池脫離系統(tong)后，一旦市電(dian)(dian)中斷，系統(tong)備(bei)用(yong)電(dian)(dian)池供電(dian)(dian)時間明顯縮短，何況此(ci)時尚不清楚另一組(zu)(zu)(zu)在線電(dian)(dian)池是否(fou)存在質量題目(mu)，此(ci)放電(dian)(dian)方式事故風險(xian)性(xing)高。如要用(yong)此(ci)方式放電(dian)(dian)，建議提前啟用(yong)發動(dong)機組(zu)(zu)(zu)，并確(que)保(bao)(bao)發電(dian)(dian)機組(zu)(zu)(zu)、開(kai)關電(dian)(dian)源等設(she)備(bei)能正常運行，保(bao)(bao)證安全；

（2）離線放電(dian)(dian)(dian)(dian)結束后的電(dian)(dian)(dian)(dian)池組(zu)與(yu)在(zai)(zai)線電(dian)(dian)(dian)(dian)池組(zu)間存在(zai)(zai)較大(da)(da)電(dian)(dian)(dian)(dian)壓差，若操(cao)縱不當將(jiang)引起開關(guan)電(dian)(dian)(dian)(dian)源和在(zai)(zai)線電(dian)(dian)(dian)(dian)池組(zu)對(dui)(dui)離線放電(dian)(dian)(dian)(dian)后的電(dian)(dian)(dian)(dian)池組(zu)進行(xing)大(da)(da)電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，產生(sheng)(sheng)巨大(da)(da)火(huo)(huo)花(hua)，易發生(sheng)(sheng)安全事故(gu)。用此方式(shi)放電(dian)(dian)(dian)(dian)，需要配備一(yi)臺整組(zu)智(zhi)能充(chong)電(dian)(dian)(dian)(dian)機，對(dui)(dui)該離線電(dian)(dian)(dian)(dian)池組(zu)先充(chong)電(dian)(dian)(dian)(dian)恢復后再并聯回系(xi)統(tong)，以解決打火(huo)(huo)花(hua)題目，這樣將(jiang)使系(xi)統(tong)更長時間處于單組(zu)供電(dian)(dian)(dian)(dian)狀(zhuang)態，事故(gu)風險高。另通(tong)過(guo)調整整流器輸出與(yu)被(bei)放電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)池組(zu)電(dian)(dian)(dian)(dian)壓相等后進行(xing)恢復連接。上(shang)述操(cao)縱一(yi)定要謹(jin)慎(shen)操(cao)縱；

（3）此放電方(fang)式操縱時既要脫(tuo)離電池(chi)組的(de)正極(ji)，又要脫(tuo)離電池(chi)組的(de)負極(ji)，尤(you)其是脫(tuo)離電池(chi)組負極(ji)時需要特別小心，操縱不當引起(qi)負極(ji)短(duan)路，將造成系統供(gong)電中斷，導致通訊事故的(de)發生；

（4）此(ci)方式(shi)是將電(dian)池(chi)通過假負載以熱量形式(shi)消耗，浪費電(dian)能，影(ying)響機房設備運(yun)行環境，需要維護職(zhi)員時刻守護以免高溫引發(fa)事故。

1.2在線評估式放電法技術分析

（1）調整(zheng)整(zheng)流器輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)至保(bao)(bao)護低(di)壓(ya)值(zhi)（如46V），使(shi)所有后備(bei)(bei)(bei)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)直接對(dui)(dui)實際(ji)負荷進行放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)至整(zheng)流器輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)保(bao)(bao)護設置值(zhi)。由于現網系統設備(bei)(bei)(bei)盡大多數電(dian)(dian)(dian)(dian)(dian)池(chi)配置后備(bei)(bei)(bei)供電(dian)(dian)(dian)(dian)(dian)時(shi)間為1～4h，放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流大，應考慮電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)至設備(bei)(bei)(bei)供電(dian)(dian)(dian)(dian)(dian)回(hui)路壓(ya)降及(ji)設備(bei)(bei)(bei)低(di)壓(ya)工(gong)(gong)作門(men)限，以(yi)(yi)(yi)及(ji)保(bao)(bao)證系統供電(dian)(dian)(dian)(dian)(dian)安全，在線(xian)評(ping)估式放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)其調整(zheng)整(zheng)流器輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)不答應過低(di)（如46V），放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)深度(du)有限，對(dui)(dui)實際(ji)負載的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時(shi)間把握比較困難，評(ping)估電(dian)(dian)(dian)(dian)(dian)池(chi)容量難以(yi)(yi)(yi)正(zheng)確(que)，對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)性(xing)能(neng)測(ce)試(shi)有不確(que)定因素存(cun)在，從而對(dui)(dui)保(bao)(bao)持電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)活(huo)性(xing)這(zhe)一放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)試(shi)目的(de)難以(yi)(yi)(yi)達到維護預(yu)期工(gong)(gong)作效(xiao)果；

（2）假如(ru)兩(liang)組(zu)電(dian)池(chi)都(dou)有(you)失(shi)容(rong)或欠容(rong)、落后等質量題目(mu)，當其放(fang)電(dian)至整(zheng)流(liu)器輸出保護值的時間(jian)，不易被(bei)維(wei)護職員及時發現，此時可能后備電(dian)池(chi)容(rong)量所剩無(wu)幾，存在高風險。在此情況下，此放(fang)電(dian)方式(shi)比離(li)線放(fang)電(dian)方式(shi)安(an)全(quan)性更低；

（3）由(you)于放(fang)電(dian)深(shen)度(du)有(you)限，對保持電(dian)池(chi)組(zu)的(de)活性(xing)(xing)這一放(fang)電(dian)測試的(de)目的(de)無法達(da)到，更為(wei)關鍵(jian)的(de)是(shi)在(zai)全容量(liang)放(fang)電(dian)的(de)實踐中(zhong)我們經常(chang)發現有(you)些電(dian)池(chi)組(zu)在(zai)放(fang)電(dian)前期表現正常(chang)，但(dan)到中(zhong)后(hou)期，有(you)些落后(hou)電(dian)池(chi)才開始逐步暴露出來(lai)。這一部分落后(hou)單體，于此放(fang)電(dian)方式的(de)深(shen)度(du)不夠而(er)沒有(you)被發現。所以我們稱此放(fang)電(dian)方式為(wei)在(zai)線評估(gu)(gu)式，它只能大致(zhi)評估(gu)(gu)電(dian)池(chi)組(zu)性(xing)(xing)能，或檢(jian)測此電(dian)池(chi)組(zu)可以放(fang)電(dian)至(zhi)此保護(hu)電(dian)壓(ya)的(de)時(shi)間(jian)是(shi)非(fei)，而(er)無法進(jin)一步檢(jian)查除此時(shi)間(jian)外究竟(jing)還(huan)能放(fang)電(dian)多長時(shi)間(jian)；

（4）組間(jian)電(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)電(dian)(dian)流(liu)不均衡。各(ge)組電(dian)(dian)池(chi)(chi)將根據自身情(qing)況(kuang)自然分(fen)攤系統的負(fu)荷電(dian)(dian)流(liu)來放(fang)電(dian)(dian)，落(luo)后電(dian)(dian)池(chi)(chi)組，內阻大(da)，分(fen)攤電(dian)(dian)流(liu)小，而健康(kang)電(dian)(dian)池(chi)(chi)組，內阻低(di)，分(fen)攤電(dian)(dian)流(liu)大(da)，造成某些落(luo)后電(dian)(dian)池(chi)(chi)因放(fang)電(dian)(dian)電(dian)(dian)流(liu)不夠大(da)而無法暴(bao)露(lu)出來的現象，達不到(dao)我們進行放(fang)電(dian)(dian)性(xing)能質量檢測目的。

綜上所述，在(zai)中心(xin)機房蓄(xu)電(dian)(dian)(dian)池(chi)(chi)必(bi)須(xu)定期進行(xing)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)的需求下(xia)，目前兩種(zhong)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)(fang)(fang)法，各(ge)有(you)特點又各(ge)有(you)弊端，離(li)線(xian)放(fang)電(dian)(dian)(dian)方(fang)(fang)(fang)法固然可以達到(dao)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)的目的，但(dan)是工作量(liang)(liang)(liang)太大，系統安(an)全性偏(pian)低，而在(zai)線(xian)評估式放(fang)電(dian)(dian)(dian)方(fang)(fang)(fang)法固然工作量(liang)(liang)(liang)比較小，但(dan)是系統安(an)全性低，達不到(dao)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)的目的，潛伏的安(an)全隱患大。因此，當(dang)前的蓄(xu)電(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)方(fang)(fang)(fang)法必(bi)須(xu)改革，現將引進一種(zhong)全新(xin)的、科學(xue)的容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)技(ji)術(shu)——全在(zai)線(xian)放(fang)電(dian)(dian)(dian)技(ji)術(shu)，以使電(dian)(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)(dian)容量(liang)(liang)(liang)測(ce)(ce)(ce)試(shi)達到(dao)預期維護(hu)質(zhi)量(liang)(liang)(liang)檢(jian)測(ce)(ce)(ce)效(xiao)果(guo)，電(dian)(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)(dian)維護(hu)操縱(zong)簡便安(an)全，進步(bu)了(le)維護(hu)工作效(xiao)率易得到(dao)有(you)效(xiao)的落實。

2、全在線放電技術分析

全在(zai)線放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)技術(shu)指(zhi)被(bei)測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)通過串接電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)全在(zai)線放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)(ce)(ce)試設備提升(sheng)在(zai)線供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓，以自動穩流或恒(heng)(heng)功率控制輸出，使被(bei)測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)對(dui)在(zai)線負載設備進行供(gong)電(dian)(dian)(dian)(dian)(dian)，實現(xian)被(bei)測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)恒(heng)(heng)電(dian)(dian)(dian)(dian)(dian)放(fang)(fang)逐電(dian)(dian)(dian)(dian)(dian)測(ce)(ce)(ce)試或恒(heng)(heng)功率放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)(ce)(ce)試，達到安全節能維(wei)護(hu)效果。

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)測電(dian)(dian)(dian)(dian)池(chi)組放(fang)(fang)電(dian)(dian)(dian)(dian)測試(shi)結(jie)束后，電(dian)(dian)(dian)(dian)池(chi)組全(quan)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)設備(bei)自動進(jin)進(jin)充(chong)電(dian)(dian)(dian)(dian)程序，引導在(zai)(zai)(zai)線(xian)開關電(dian)(dian)(dian)(dian)源的(de)整流輸出，經(jing)過全(quan)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)測試(shi)設備(bei)的(de)充(chong)電(dian)(dian)(dian)(dian)、等電(dian)(dian)(dian)(dian)位(wei)控制保護(hu)電(dian)(dian)(dian)(dian)路自動對被(bei)測放(fang)(fang)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)池(chi)組進(jin)行(xing)限(xian)流充(chong)電(dian)(dian)(dian)(dian)，自動完(wan)成在(zai)(zai)(zai)線(xian)等電(dian)(dian)(dian)(dian)位(wei)連(lian)接，根據全(quan)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)測試(shi)設備(bei)系統(tong)提示操縱要(yao)求，恢復系統(tong)的(de)正常連(lian)接后，全(quan)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)測試(shi)設備(bei)退出服(fu)務(wu)，完(wan)成結(jie)束蓄電(dian)(dian)(dian)(dian)池(chi)組全(quan)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)、充(chong)電(dian)(dian)(dian)(dian)恢復等電(dian)(dian)(dian)(dian)位(wei)正常連(lian)接全(quan)過程。另一組電(dian)(dian)(dian)(dian)池(chi)以同樣的(de)方式進(jin)行(xing)在(zai)(zai)(zai)線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)容量測試(shi)。如圖4所示。

2.2在線放電“無縫連接”技術

為確保電池(chi)放電測(ce)試的安全(quan)性(xing)，電池(chi)組(zu)全(quan)在(zai)線(xian)放電設備(bei)在(zai)串聯(lian)接進(jin)電池(chi)組(zu)正(zheng)極時要求以(yi)無(wu)縫連接方(fang)式，如圖5所(suo)示。

電(dian)(dian)池組在線(xian)放(fang)電(dian)(dian)測試(shi)(shi)無縫連接(jie)(jie)操縱(zong)，“設備”接(jie)(jie)進應(ying)遵守“先(xian)接(jie)(jie)三，后拆(chai)一(yi)”，即為先(xian)接(jie)(jie)電(dian)(dian)源(yuan)線(xian)L1、L2、L3，后拆(chai)原電(dian)(dian)源(yuan)連接(jie)(jie)線(xian)L5；“設備”成(cheng)測試(shi)(shi)退出服務，應(ying)遵守“先(xian)接(jie)(jie)一(yi)，后拆(chai)三”的原則，即為先(xian)接(jie)(jie)原電(dian)(dian)源(yuan)連接(jie)(jie)線(xian)L5，后拆(chai)電(dian)(dian)源(yuan)線(xian)L1、L2、L3。

3、在線放電技術與當前放電技術對比分析

3.1與離線放電技術對比分析

（1）放電(dian)過程最(zui)大(da)限度(du)保證電(dian)池(chi)組備用電(dian)能，最(zui)大(da)限度(du)降低放電(dian)測試造成(cheng)系(xi)統癱瘓的風險(xian)；

（2）電(dian)池組放電(dian)后(hou)能自(zi)動進行充(chong)電(dian)恢復，克服離線(xian)放電(dian)后(hou)等(deng)電(dian)位接進系統操縱難度大及潛伏安全等(deng)題目；

（3）電(dian)池組存儲的電(dian)能最大限度地得到利用，克服了離線放電(dian)能源的浪費，基(ji)本沒(mei)有發(fa)熱現(xian)象，不存在高溫的危險，不影響(xiang)機房環境溫度；

（4）僅(jin)在(zai)電池組的正極進(jin)行無縫連接(jie)操縱，避(bi)免了(le)離(li)線放(fang)電因操縱不當引起的短(duan)路風險(xian)；

（5）該設備一旦串聯接進(jin)電池(chi)組的(de)正極，設定相關放(fang)電參數后(hou)，所有放(fang)電充電工(gong)作(zuo)自(zi)動(dong)完(wan)成，維(wei)護職員可以進(jin)行其(qi)它工(gong)作(zuo)，降低工(gong)作(zuo)強度，進(jin)步工(gong)作(zuo)效(xiao)率。

3.2與在線評估式放電技術對比分析

（1）全在線放(fang)(fang)電(dian)方(fang)式能(neng)夠達(da)到深度放(fang)(fang)電(dian)保(bao)持電(dian)池(chi)活(huo)性及檢測落后(hou)電(dian)池(chi)的放(fang)(fang)電(dian)測試(shi)目的，充分(fen)把握電(dian)池(chi)組剩(sheng)余容量和(he)后(hou)備供電(dian)時(shi)間；

（2）在放電過(guo)程中最(zui)大限度(du)(du)地(di)(di)保證電池組備用電能，最(zui)大限度(du)(du)地(di)(di)降低了容量測試造成系(xi)統癱瘓的風險；

（3）全在(zai)線放(fang)電方(fang)式能(neng)夠實(shi)現各組電池(chi)以相(xiang)同電流進(jin)行分(fen)組放(fang)電，任何落后單體電池(chi)都(dou)能(neng)暴露(lu)出來，克服了在(zai)線評(ping)估式放(fang)電的局限(xian)性；

（4）全在(zai)線放電(dian)設備一旦串聯接進電(dian)池組的正(zheng)極，設定相關(guan)放電(dian)參數后(hou)，所有放電(dian)充電(dian)工作自動完成，維(wei)護職員可以進行其它工作，降低工作強(qiang)度，進步(bu)工作效率。
