【蓄電池(chi)容(rong)量】蓄電池(chi)容(rong)量計算公式(shi) 蓄電池(chi)容(rong)量測試新技術介紹

蓄電池容量計算公式

容量=放(fang)電電流×放(fang)電時間

蓄電(dian)(dian)(dian)池的(de)(de)容量與放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)大小及電(dian)(dian)(dian)解液的(de)(de)溫度有(you)關，因此標稱容量是(shi)在一(yi)定(ding)(ding)的(de)(de)放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)、一(yi)定(ding)(ding)的(de)(de)終止電(dian)(dian)(dian)壓和一(yi)定(ding)(ding)的(de)(de)電(dian)(dian)(dian)解液溫度下取(qu)得的(de)(de)，標容量有(you)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(kuang)下，以20小時(shi)率(lv)放電的(de)電流（相(xiang)當于額定(ding)容量(liang)的(de)1/20）連續放電至單體1.75V時輸出的電(dian)量。

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(bei)額定容(rong)量(liang)電流(liu)）連續(xu)放電至規(gui)定的終止電壓（6V蓄(xu)電池為4.5V，12V蓄電池為(wei)9V）時，所輸出(chu)的電量，其放電持續(xu)時間應在5min以(yi)上(shang)

低溫起動容量：電解液溫度為-18℃時，以(yi)3倍(bei)額定容量的電(dian)流連續放電(dian)至規定終(zhong)止電(dian)壓(ya)（12V蓄電池為6V，6V蓄電(dian)池為(wei)3V）時所(suo)放出的電(dian)量，其放電(dian)持續時間(jian)應在2.5min以(yi)上。

蓄電池容量測試新技術介紹

通(tong)訊(xun)后備蓄(xu)電(dian)池(chi)質量(liang)是(shi)通(tong)訊(xun)網(wang)絡供(gong)電(dian)不(bu)中斷(duan)的(de)重要保障，是(shi)整個(ge)通(tong)訊(xun)電(dian)源設(she)備供(gong)電(dian)保障，保證通(tong)訊(xun)網(wang)絡正常(chang)運行的(de)最后一(yi)道防(fang)線。根據蓄(xu)電(dian)池(chi)特(te)性(xing)和維護要求，蓄(xu)電(dian)池(chi)放電(dian)容量(liang)測試工作是(shi)必不(bu)可少的(de)。

隨著(zhu)通訊(xun)網(wang)絡規模的迅猛發展，現網(wang)電(dian)源(yuan)維(wei)護專業技術職員相對較少，當前(qian)電(dian)池放電(dian)容量測(ce)(ce)試(shi)方式存在(zai)安(an)全隱患，操縱復雜，測(ce)(ce)試(shi)工作量大的題目(mu)，致使維(wei)護規程要求的電(dian)池放電(dian)測(ce)(ce)試(shi)工作得(de)不(bu)到有效落實，落后(hou)電(dian)池不(bu)能及時得(de)到預警和(he)維(wei)護，在(zai)用電(dian)池往(wang)往(wang)被(bei)提前(qian)報廢(fei)，造成資源(yuan)浪費。

團體公司、福建公司針(zhen)對電(dian)池放(fang)(fang)電(dian)技(ji)(ji)術(shu)(shu)聯合進行(xing)研究，導進了創(chuang)新性的(de)全在線電(dian)池放(fang)(fang)電(dian)技(ji)(ji)術(shu)(shu)，全面解決(jue)了幾(ji)十年來原電(dian)池放(fang)(fang)電(dian)技(ji)(ji)術(shu)(shu)中存在的(de)安全隱(yin)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）將其中一組(zu)電(dian)(dian)(dian)池脫離系(xi)(xi)統后，一旦市電(dian)(dian)(dian)中斷，系(xi)(xi)統備(bei)(bei)用電(dian)(dian)(dian)池供電(dian)(dian)(dian)時(shi)間明顯縮短，何況此時(shi)尚不清楚(chu)另一組(zu)在(zai)線電(dian)(dian)(dian)池是(shi)否存在(zai)質量題(ti)目，此放電(dian)(dian)(dian)方式事故風(feng)險(xian)性高(gao)。如要(yao)用此方式放電(dian)(dian)(dian)，建(jian)議提(ti)前(qian)啟用發(fa)動機(ji)組(zu)，并確保(bao)發(fa)電(dian)(dian)(dian)機(ji)組(zu)、開(kai)關(guan)電(dian)(dian)(dian)源等設備(bei)(bei)能正(zheng)常運行，保(bao)證安全(quan)；

（2）離(li)線(xian)(xian)放(fang)電(dian)(dian)結束后(hou)(hou)的電(dian)(dian)池組(zu)與(yu)(yu)在線(xian)(xian)電(dian)(dian)池組(zu)間(jian)存在較大電(dian)(dian)壓差，若操(cao)縱不當將引起開關電(dian)(dian)源和在線(xian)(xian)電(dian)(dian)池組(zu)對(dui)離(li)線(xian)(xian)放(fang)電(dian)(dian)后(hou)(hou)的電(dian)(dian)池組(zu)進(jin)行大電(dian)(dian)流充(chong)電(dian)(dian)，產生巨大火(huo)花(hua)，易發生安全事(shi)故。用(yong)此(ci)方式放(fang)電(dian)(dian)，需要配備一臺(tai)整組(zu)智能充(chong)電(dian)(dian)機，對(dui)該離(li)線(xian)(xian)電(dian)(dian)池組(zu)先(xian)充(chong)電(dian)(dian)恢復后(hou)(hou)再并聯回系統(tong)(tong)，以解決打火(huo)花(hua)題目，這樣將使(shi)系統(tong)(tong)更(geng)長時間(jian)處于單(dan)組(zu)供電(dian)(dian)狀態，事(shi)故風險高。另(ling)通過調(diao)整整流器輸出與(yu)(yu)被(bei)放(fang)電(dian)(dian)的電(dian)(dian)池組(zu)電(dian)(dian)壓相等后(hou)(hou)進(jin)行恢復連接。上(shang)述操(cao)縱一定要謹慎(shen)操(cao)縱；

（3）此放電(dian)(dian)方(fang)式操縱(zong)時(shi)既(ji)要(yao)(yao)脫(tuo)離(li)電(dian)(dian)池(chi)(chi)組的(de)正極，又要(yao)(yao)脫(tuo)離(li)電(dian)(dian)池(chi)(chi)組的(de)負(fu)極，尤其是脫(tuo)離(li)電(dian)(dian)池(chi)(chi)組負(fu)極時(shi)需要(yao)(yao)特別小心，操縱(zong)不當引起負(fu)極短路，將造成(cheng)系(xi)統供(gong)電(dian)(dian)中斷，導(dao)致通訊事(shi)故的(de)發生；

（4）此(ci)方式(shi)是(shi)將電(dian)池通(tong)過假(jia)負載(zai)以熱量(liang)形式(shi)消耗，浪費電(dian)能，影(ying)響機房設(she)備運行環境，需要維護職員(yuan)時(shi)刻守護以免高溫引(yin)發事故。

1.2在線評估式放電法技術分析

（1）調(diao)整(zheng)整(zheng)流(liu)(liu)器(qi)輸出電(dian)(dian)壓至(zhi)保(bao)(bao)(bao)護低壓值（如46V），使(shi)所(suo)有(you)后(hou)備電(dian)(dian)池(chi)(chi)(chi)組直接對實(shi)際(ji)負荷進行(xing)放電(dian)(dian)至(zhi)整(zheng)流(liu)(liu)器(qi)輸出電(dian)(dian)壓保(bao)(bao)(bao)護設(she)(she)置(zhi)值。由于現(xian)網(wang)系(xi)統設(she)(she)備盡大多數電(dian)(dian)池(chi)(chi)(chi)配置(zhi)后(hou)備供電(dian)(dian)時間為1～4h，放電(dian)(dian)電(dian)(dian)流(liu)(liu)大，應考慮(lv)電(dian)(dian)池(chi)(chi)(chi)組至(zhi)設(she)(she)備供電(dian)(dian)回路壓降及(ji)設(she)(she)備低壓工作門(men)限，以(yi)及(ji)保(bao)(bao)(bao)證系(xi)統供電(dian)(dian)安全，在(zai)(zai)線評(ping)(ping)估式放電(dian)(dian)其調(diao)整(zheng)整(zheng)流(liu)(liu)器(qi)輸出電(dian)(dian)壓不(bu)答應過低（如46V），放電(dian)(dian)深(shen)度有(you)限，對實(shi)際(ji)負載的(de)放電(dian)(dian)時間把(ba)握(wo)比較困難(nan)，評(ping)(ping)估電(dian)(dian)池(chi)(chi)(chi)容量難(nan)以(yi)正確，對電(dian)(dian)池(chi)(chi)(chi)性能測(ce)試有(you)不(bu)確定(ding)因素存在(zai)(zai)，從而(er)對保(bao)(bao)(bao)持電(dian)(dian)池(chi)(chi)(chi)組活性這一放電(dian)(dian)測(ce)試目的(de)難(nan)以(yi)達到維(wei)護預期工作效(xiao)果；

（2）假如兩組(zu)電池(chi)都有失容或欠容、落后(hou)等質量題目，當其放(fang)電至整流(liu)器(qi)輸出保(bao)護值的時(shi)間，不易被維護職(zhi)員及時(shi)發現(xian)，此時(shi)可能后(hou)備電池(chi)容量所(suo)剩無幾，存在(zai)高風險。在(zai)此情況下，此放(fang)電方(fang)式(shi)比離線放(fang)電方(fang)式(shi)安(an)全性更(geng)低；

（3）由于放(fang)電(dian)(dian)(dian)(dian)深度(du)有限(xian)，對(dui)保持電(dian)(dian)(dian)(dian)池(chi)組的(de)(de)(de)活性這一放(fang)電(dian)(dian)(dian)(dian)測試的(de)(de)(de)目的(de)(de)(de)無法(fa)(fa)達(da)到，更為(wei)(wei)關鍵的(de)(de)(de)是在全容(rong)量放(fang)電(dian)(dian)(dian)(dian)的(de)(de)(de)實踐中我(wo)們經常發現有些(xie)電(dian)(dian)(dian)(dian)池(chi)組在放(fang)電(dian)(dian)(dian)(dian)前期表現正常，但到中后期，有些(xie)落后電(dian)(dian)(dian)(dian)池(chi)才開始逐步暴露出(chu)來(lai)。這一部(bu)分落后單(dan)體，于此(ci)(ci)放(fang)電(dian)(dian)(dian)(dian)方式(shi)的(de)(de)(de)深度(du)不夠(gou)而沒有被發現。所以我(wo)們稱此(ci)(ci)放(fang)電(dian)(dian)(dian)(dian)方式(shi)為(wei)(wei)在線評估式(shi)，它(ta)只(zhi)能大(da)致評估電(dian)(dian)(dian)(dian)池(chi)組性能，或檢測此(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)組可以放(fang)電(dian)(dian)(dian)(dian)至此(ci)(ci)保護電(dian)(dian)(dian)(dian)壓的(de)(de)(de)時(shi)間(jian)是非，而無法(fa)(fa)進一步檢查除此(ci)(ci)時(shi)間(jian)外究(jiu)竟還能放(fang)電(dian)(dian)(dian)(dian)多(duo)長時(shi)間(jian)；

（4）組間電(dian)(dian)池(chi)放(fang)電(dian)(dian)電(dian)(dian)流不(bu)均衡。各組電(dian)(dian)池(chi)將根(gen)據自身(shen)情(qing)況自然分攤系統的負(fu)荷(he)電(dian)(dian)流來放(fang)電(dian)(dian)，落后(hou)電(dian)(dian)池(chi)組，內(nei)阻大，分攤電(dian)(dian)流小，而(er)健康電(dian)(dian)池(chi)組，內(nei)阻低(di)，分攤電(dian)(dian)流大，造成某些(xie)落后(hou)電(dian)(dian)池(chi)因(yin)放(fang)電(dian)(dian)電(dian)(dian)流不(bu)夠(gou)大而(er)無法暴(bao)露出來的現象，達不(bu)到我(wo)們進行(xing)放(fang)電(dian)(dian)性能質量(liang)檢(jian)測目(mu)的。

綜上所(suo)述，在中心機房蓄(xu)電(dian)(dian)(dian)(dian)池(chi)必須定(ding)期(qi)進(jin)行(xing)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)的需求下，目前兩種(zhong)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)方法(fa)(fa)，各(ge)有(you)特點又(you)各(ge)有(you)弊端，離線(xian)放(fang)電(dian)(dian)(dian)(dian)方法(fa)(fa)固(gu)然(ran)可以(yi)達(da)(da)到(dao)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)的目的，但(dan)是工作量(liang)(liang)(liang)(liang)(liang)(liang)太大，系統安(an)全(quan)性偏(pian)低，而在線(xian)評(ping)估式放(fang)電(dian)(dian)(dian)(dian)方法(fa)(fa)固(gu)然(ran)工作量(liang)(liang)(liang)(liang)(liang)(liang)比較小(xiao)，但(dan)是系統安(an)全(quan)性低，達(da)(da)不到(dao)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)的目的，潛伏的安(an)全(quan)隱患大。因(yin)此，當前的蓄(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)方法(fa)(fa)必須改革(ge)，現將(jiang)引進(jin)一種(zhong)全(quan)新的、科學的容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)技術(shu)——全(quan)在線(xian)放(fang)電(dian)(dian)(dian)(dian)技術(shu)，以(yi)使(shi)電(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)(liang)(liang)(liang)(liang)(liang)測試(shi)達(da)(da)到(dao)預期(qi)維(wei)護(hu)(hu)質量(liang)(liang)(liang)(liang)(liang)(liang)檢測效(xiao)果(guo)，電(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)維(wei)護(hu)(hu)操縱(zong)簡便安(an)全(quan)，進(jin)步(bu)了維(wei)護(hu)(hu)工作效(xiao)率易得到(dao)有(you)效(xiao)的落實。

2.1在線放電結束后，自動完成在線充電恢復等電位連接

被測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測試(shi)結束(shu)后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)全(quan)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)(she)備(bei)自動(dong)進進充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)程序(xu)，引導(dao)在線(xian)開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源的整(zheng)流輸出，經過全(quan)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測試(shi)設(she)(she)(she)備(bei)的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、等(deng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)控制保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路自動(dong)對被測放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)進行(xing)(xing)限流充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，自動(dong)完成在線(xian)等(deng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)連(lian)接，根據全(quan)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測試(shi)設(she)(she)(she)備(bei)系統(tong)提(ti)示(shi)操縱要求，恢(hui)復(fu)系統(tong)的正(zheng)常連(lian)接后，全(quan)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測試(shi)設(she)(she)(she)備(bei)退出服務，完成結束(shu)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)全(quan)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)恢(hui)復(fu)等(deng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)正(zheng)常連(lian)接全(quan)過程。另一組(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)以同樣的方式進行(xing)(xing)在線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容量(liang)測試(shi)。如(ru)圖(tu)4所示(shi)。

2.2在線放電“無縫連接”技術

為(wei)確(que)保電池(chi)放(fang)電測(ce)試的安全性，電池(chi)組(zu)全在線放(fang)電設備在串聯接進電池(chi)組(zu)正(zheng)極時要(yao)求以無(wu)縫連(lian)接方式，如(ru)圖5所示。

電(dian)池組在線(xian)放電(dian)測試(shi)無(wu)縫連(lian)接操(cao)縱，“設備(bei)”接進應(ying)遵守(shou)(shou)“先(xian)接三，后(hou)拆(chai)(chai)一”，即為(wei)先(xian)接電(dian)源(yuan)線(xian)L1、L2、L3，后(hou)拆(chai)(chai)原電(dian)源(yuan)連(lian)接線(xian)L5；“設備(bei)”成測試(shi)退出服務(wu)，應(ying)遵守(shou)(shou)“先(xian)接一，后(hou)拆(chai)(chai)三”的原則(ze)，即為(wei)先(xian)接原電(dian)源(yuan)連(lian)接線(xian)L5，后(hou)拆(chai)(chai)電(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)(dian)過程(cheng)最(zui)(zui)大(da)限度保(bao)證電(dian)(dian)池(chi)組(zu)備用電(dian)(dian)能(neng)，最(zui)(zui)大(da)限度降低放電(dian)(dian)測試(shi)造(zao)成(cheng)系統(tong)癱瘓(huan)的風險(xian)；

（2）電(dian)(dian)池(chi)組放電(dian)(dian)后能(neng)自動進行充電(dian)(dian)恢(hui)復(fu)，克服離線放電(dian)(dian)后等(deng)電(dian)(dian)位(wei)接進系統(tong)操縱(zong)難度大及潛伏安全等(deng)題目(mu)；

（3）電池組存儲的電能最大限(xian)度(du)地得到(dao)利(li)用，克服了離線放電能源的浪(lang)費，基本沒有發(fa)熱現象，不存在高溫的危險，不影響(xiang)機房環境溫度(du)；

（4）僅在電池組的(de)正極(ji)進行無縫連(lian)接操(cao)縱，避免(mian)了(le)離線(xian)放電因操(cao)縱不當(dang)引起(qi)的(de)短路(lu)風險；

（5）該設(she)備一旦串聯(lian)接進電(dian)池(chi)組的正極，設(she)定相關放(fang)電(dian)參數(shu)后，所有放(fang)電(dian)充電(dian)工作自(zi)動完成(cheng)，維護(hu)職員可以進行其它工作，降(jiang)低工作強度，進步工作效率(lv)。

3.2與在線評估式放電技術對比分析

（1）全在線放電(dian)(dian)方式能(neng)夠(gou)達(da)到(dao)深度放電(dian)(dian)保持(chi)電(dian)(dian)池(chi)活(huo)性及檢測(ce)落后(hou)電(dian)(dian)池(chi)的(de)放電(dian)(dian)測(ce)試目的(de)，充分把握電(dian)(dian)池(chi)組剩余容量(liang)和后(hou)備供電(dian)(dian)時間；
