【蓄(xu)電池(chi)容(rong)(rong)量(liang)】蓄(xu)電池(chi)容(rong)(rong)量(liang)計算公式 蓄(xu)電池(chi)容(rong)(rong)量(liang)測試新技(ji)術(shu)介紹

蓄電池容量計算公式

容量=放(fang)(fang)電電流(liu)×放(fang)(fang)電時間

蓄電(dian)池的(de)容(rong)量(liang)與放(fang)(fang)電(dian)電(dian)流大小及(ji)電(dian)解液(ye)(ye)的(de)溫度(du)有關，因此(ci)標(biao)稱容(rong)量(liang)是在一(yi)定(ding)的(de)放(fang)(fang)電(dian)電(dian)流、一(yi)定(ding)的(de)終(zhong)止(zhi)電(dian)壓(ya)和一(yi)定(ding)的(de)電(dian)解液(ye)(ye)溫度(du)下取(qu)得的(de)，標(biao)容(rong)量(liang)有兩種。

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(de)情況(kuang)下，以20小(xiao)時率放電(dian)的電(dian)流（相當(dang)于額(e)定容量的1/20）連(lian)續放(fang)電至單體(ti)1.75V時(shi)輸出的(de)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倍額定容量電(dian)流）連續(xu)放(fang)電(dian)至規定的(de)終(zhong)止(zhi)電(dian)壓（6V蓄電池為4.5V，12V蓄電池為9V）時，所輸出的(de)電量，其放電持續時間(jian)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(rong)量的電流連(lian)續(xu)放電至規定終止電壓（12V蓄電池為6V，6V蓄電池(chi)為3V）時所放出的(de)電(dian)量，其(qi)放電(dian)持續時間(jian)應在2.5min以上。

蓄電池容量測試新技術介紹

通(tong)訊后備蓄(xu)(xu)電池(chi)(chi)質量是通(tong)訊網絡(luo)供電不中斷的(de)重要(yao)保障(zhang)，是整(zheng)個(ge)通(tong)訊電源設備供電保障(zhang)，保證通(tong)訊網絡(luo)正(zheng)常運行的(de)最后一(yi)道(dao)防線。根(gen)據(ju)蓄(xu)(xu)電池(chi)(chi)特性和維護要(yao)求(qiu)，蓄(xu)(xu)電池(chi)(chi)放電容(rong)量測(ce)試工作是必(bi)不可少(shao)的(de)。

隨著通訊網絡規模的(de)迅猛發展，現網電(dian)(dian)源(yuan)維護(hu)(hu)專(zhuan)業技術(shu)職(zhi)員相對較少，當前電(dian)(dian)池(chi)放(fang)電(dian)(dian)容量測試方式存(cun)在(zai)安全隱患，操(cao)縱復雜，測試工作量大的(de)題(ti)目(mu)，致使維護(hu)(hu)規程要(yao)求的(de)電(dian)(dian)池(chi)放(fang)電(dian)(dian)測試工作得不到(dao)有效落(luo)實，落(luo)后(hou)電(dian)(dian)池(chi)不能及時(shi)得到(dao)預警和維護(hu)(hu)，在(zai)用(yong)電(dian)(dian)池(chi)往(wang)往(wang)被提前報廢(fei)，造成(cheng)資源(yuan)浪費(fei)。

團體公司、福建(jian)公司針(zhen)對電(dian)(dian)池(chi)放電(dian)(dian)技(ji)(ji)術(shu)聯合進行(xing)研究(jiu)，導進了(le)創新性的(de)全在(zai)線電(dian)(dian)池(chi)放電(dian)(dian)技(ji)(ji)術(shu)，全面解決了(le)幾十年來原電(dian)(dian)池(chi)放電(dian)(dian)技(ji)(ji)術(shu)中存在(zai)的(de)安全隱患題目。

1、當前電池放電技術分析

1.1離線式放電法技術分析

（1）將其中一(yi)組(zu)電(dian)池脫離(li)系統后，一(yi)旦市(shi)電(dian)中斷，系統備用(yong)(yong)電(dian)池供電(dian)時間(jian)明顯縮(suo)短，何況此時尚不清楚另一(yi)組(zu)在線電(dian)池是否存在質量(liang)題目(mu)，此放電(dian)方(fang)式事(shi)故(gu)風險(xian)性高。如要用(yong)(yong)此方(fang)式放電(dian)，建議提(ti)前啟用(yong)(yong)發(fa)動機組(zu)，并確保(bao)發(fa)電(dian)機組(zu)、開關(guan)電(dian)源等設(she)備能正(zheng)常運行(xing)，保(bao)證安全；

（2）離線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)結(jie)束(shu)后的電(dian)(dian)(dian)(dian)池(chi)(chi)組與在線(xian)電(dian)(dian)(dian)(dian)池(chi)(chi)組間存在較大(da)電(dian)(dian)(dian)(dian)壓差(cha)，若操縱不當將引起開關電(dian)(dian)(dian)(dian)源和(he)在線(xian)電(dian)(dian)(dian)(dian)池(chi)(chi)組對(dui)離線(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)后的電(dian)(dian)(dian)(dian)池(chi)(chi)組進行大(da)電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，產生巨(ju)大(da)火花，易發生安全事(shi)故。用此方(fang)式放(fang)(fang)電(dian)(dian)(dian)(dian)，需要配備一(yi)臺整(zheng)(zheng)組智能充(chong)電(dian)(dian)(dian)(dian)機，對(dui)該離線(xian)電(dian)(dian)(dian)(dian)池(chi)(chi)組先充(chong)電(dian)(dian)(dian)(dian)恢復(fu)后再并(bing)聯回系統，以解(jie)決打火花題目(mu)，這樣將使(shi)系統更(geng)長時間處于(yu)單組供電(dian)(dian)(dian)(dian)狀(zhuang)態(tai)，事(shi)故風險(xian)高。另(ling)通過調整(zheng)(zheng)整(zheng)(zheng)流器輸出(chu)與被放(fang)(fang)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)池(chi)(chi)組電(dian)(dian)(dian)(dian)壓相等后進行恢復(fu)連接。上述操縱一(yi)定要謹慎(shen)操縱；

（3）此放電(dian)方式(shi)操(cao)縱時既(ji)要脫離電(dian)池組的(de)正(zheng)極，又(you)要脫離電(dian)池組的(de)負(fu)(fu)極，尤(you)其是脫離電(dian)池組負(fu)(fu)極時需要特別(bie)小心，操(cao)縱不(bu)當引(yin)起負(fu)(fu)極短(duan)路，將造成(cheng)系(xi)統供電(dian)中斷，導致通訊事故的(de)發生；

（4）此方式是將電池通過(guo)假負(fu)載以(yi)(yi)熱(re)量形式消耗(hao)，浪費電能(neng)，影(ying)響(xiang)機(ji)房設備(bei)運行環境(jing)，需要(yao)維護(hu)職(zhi)員時(shi)刻守護(hu)以(yi)(yi)免高溫(wen)引發事故。

1.2在線評估式放電法技術分析

（1）調整(zheng)(zheng)(zheng)(zheng)整(zheng)(zheng)(zheng)(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)至(zhi)保(bao)護(hu)低(di)壓(ya)值（如46V），使所有(you)后(hou)備(bei)(bei)電(dian)(dian)(dian)池(chi)(chi)組(zu)直接對(dui)(dui)實(shi)際負荷進行放(fang)(fang)電(dian)(dian)(dian)至(zhi)整(zheng)(zheng)(zheng)(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)保(bao)護(hu)設置值。由(you)于現網系統設備(bei)(bei)盡(jin)大多數電(dian)(dian)(dian)池(chi)(chi)配置后(hou)備(bei)(bei)供(gong)電(dian)(dian)(dian)時間(jian)為1～4h，放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流大，應考慮(lv)電(dian)(dian)(dian)池(chi)(chi)組(zu)至(zhi)設備(bei)(bei)供(gong)電(dian)(dian)(dian)回(hui)路壓(ya)降及(ji)設備(bei)(bei)低(di)壓(ya)工(gong)作門(men)限，以(yi)及(ji)保(bao)證系統供(gong)電(dian)(dian)(dian)安全，在線評估式放(fang)(fang)電(dian)(dian)(dian)其調整(zheng)(zheng)(zheng)(zheng)整(zheng)(zheng)(zheng)(zheng)流器(qi)輸(shu)出電(dian)(dian)(dian)壓(ya)不答應過低(di)（如46V），放(fang)(fang)電(dian)(dian)(dian)深度有(you)限，對(dui)(dui)實(shi)際負載的放(fang)(fang)電(dian)(dian)(dian)時間(jian)把握比較困(kun)難，評估電(dian)(dian)(dian)池(chi)(chi)容量難以(yi)正確，對(dui)(dui)電(dian)(dian)(dian)池(chi)(chi)性(xing)(xing)能(neng)測(ce)(ce)試有(you)不確定因素存在，從而(er)對(dui)(dui)保(bao)持電(dian)(dian)(dian)池(chi)(chi)組(zu)活性(xing)(xing)這一放(fang)(fang)電(dian)(dian)(dian)測(ce)(ce)試目的難以(yi)達到(dao)維(wei)護(hu)預(yu)期工(gong)作效果；

（2）假(jia)如兩組電(dian)池都有(you)失(shi)容或(huo)欠容、落(luo)后等質量題目，當其放電(dian)至(zhi)整(zheng)流(liu)器輸出(chu)保護值的時(shi)間，不易被維護職員及時(shi)發(fa)現，此(ci)(ci)時(shi)可能(neng)后備電(dian)池容量所剩無(wu)幾，存在高(gao)風(feng)險。在此(ci)(ci)情(qing)況下，此(ci)(ci)放電(dian)方式比離線放電(dian)方式安全(quan)性更低；

（3）由于放(fang)電(dian)(dian)深(shen)(shen)度有限(xian)，對(dui)保持電(dian)(dian)池組(zu)(zu)的活(huo)性(xing)這一(yi)放(fang)電(dian)(dian)測試的目的無(wu)(wu)法達(da)到(dao)，更(geng)為關鍵的是在全容量放(fang)電(dian)(dian)的實踐中我(wo)們經常發現有些電(dian)(dian)池組(zu)(zu)在放(fang)電(dian)(dian)前期表(biao)現正常，但(dan)到(dao)中后期，有些落(luo)后電(dian)(dian)池才(cai)開始逐步暴露出(chu)來。這一(yi)部分落(luo)后單體，于此(ci)(ci)放(fang)電(dian)(dian)方式的深(shen)(shen)度不夠而沒有被發現。所以我(wo)們稱此(ci)(ci)放(fang)電(dian)(dian)方式為在線評估式，它只能(neng)大(da)致評估電(dian)(dian)池組(zu)(zu)性(xing)能(neng)，或檢測此(ci)(ci)電(dian)(dian)池組(zu)(zu)可以放(fang)電(dian)(dian)至此(ci)(ci)保護電(dian)(dian)壓的時(shi)間(jian)是非，而無(wu)(wu)法進一(yi)步檢查(cha)除(chu)此(ci)(ci)時(shi)間(jian)外究竟還能(neng)放(fang)電(dian)(dian)多長時(shi)間(jian)；

（4）組(zu)間電(dian)池放(fang)(fang)電(dian)電(dian)流(liu)不(bu)均衡。各(ge)組(zu)電(dian)池將根(gen)據自(zi)身情況自(zi)然分(fen)攤系統的(de)負荷電(dian)流(liu)來放(fang)(fang)電(dian)，落后(hou)電(dian)池組(zu)，內(nei)阻大，分(fen)攤電(dian)流(liu)小，而健康電(dian)池組(zu)，內(nei)阻低，分(fen)攤電(dian)流(liu)大，造成某些落后(hou)電(dian)池因放(fang)(fang)電(dian)電(dian)流(liu)不(bu)夠大而無(wu)法暴露(lu)出(chu)來的(de)現象，達不(bu)到我們進行放(fang)(fang)電(dian)性能(neng)質量檢測目的(de)。

綜上所述(shu)，在中(zhong)心機房蓄(xu)(xu)電(dian)池(chi)(chi)必(bi)須(xu)定期(qi)進(jin)行(xing)容(rong)量(liang)(liang)(liang)測(ce)試的(de)需求下，目(mu)前(qian)兩種(zhong)容(rong)量(liang)(liang)(liang)測(ce)試方(fang)法，各(ge)有特點(dian)又各(ge)有弊端(duan)，離線放電(dian)方(fang)法固然(ran)可以(yi)達到(dao)(dao)蓄(xu)(xu)電(dian)池(chi)(chi)容(rong)量(liang)(liang)(liang)測(ce)試的(de)目(mu)的(de)，但是工(gong)作(zuo)量(liang)(liang)(liang)太大，系統(tong)(tong)安全(quan)性偏低(di)，而在線評估(gu)式放電(dian)方(fang)法固然(ran)工(gong)作(zuo)量(liang)(liang)(liang)比較小(xiao)，但是系統(tong)(tong)安全(quan)性低(di)，達不到(dao)(dao)蓄(xu)(xu)電(dian)池(chi)(chi)容(rong)量(liang)(liang)(liang)測(ce)試的(de)目(mu)的(de)，潛伏的(de)安全(quan)隱患大。因此，當前(qian)的(de)蓄(xu)(xu)電(dian)池(chi)(chi)容(rong)量(liang)(liang)(liang)測(ce)試方(fang)法必(bi)須(xu)改革，現將引進(jin)一種(zhong)全(quan)新的(de)、科學(xue)的(de)容(rong)量(liang)(liang)(liang)測(ce)試技(ji)(ji)術——全(quan)在線放電(dian)技(ji)(ji)術，以(yi)使電(dian)池(chi)(chi)放電(dian)容(rong)量(liang)(liang)(liang)測(ce)試達到(dao)(dao)預(yu)期(qi)維護質量(liang)(liang)(liang)檢測(ce)效果，電(dian)池(chi)(chi)放電(dian)維護操縱簡便(bian)安全(quan)，進(jin)步了(le)維護工(gong)作(zuo)效率易得到(dao)(dao)有效的(de)落實。

2、全在線放電技術分析

全在線(xian)放(fang)電(dian)(dian)(dian)技術(shu)指被(bei)測電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)通(tong)過串接電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)全在線(xian)放(fang)電(dian)(dian)(dian)測試(shi)設備提升在線(xian)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓，以自動穩(wen)流(liu)或(huo)恒(heng)功(gong)率(lv)控(kong)制輸(shu)出，使被(bei)測電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)對(dui)在線(xian)負(fu)載設備進行供電(dian)(dian)(dian)，實現被(bei)測電(dian)(dian)(dian)池(chi)(chi)(chi)組(zu)恒(heng)電(dian)(dian)(dian)放(fang)逐電(dian)(dian)(dian)測試(shi)或(huo)恒(heng)功(gong)率(lv)放(fang)電(dian)(dian)(dian)測試(shi)，達到安全節能維護效果。

放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)技術原理如(ru)圖2所示。被測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)的(de)(de)全(quan)在(zai)(zai)(zai)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)原理分析：如(ru)圖2所示，在(zai)(zai)(zai)被測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)的(de)(de)正極串聯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)全(quan)在(zai)(zai)(zai)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)(bei)，使被測(ce)組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池所在(zai)(zai)(zai)支路(lu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)略(lve)高出整流(liu)器(qi)輸(shu)出或(huo)另(ling)一組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，這樣(yang)就能使該組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池對(dui)實際負荷進行(xing)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在(zai)(zai)(zai)其放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程被測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)隨著(zhu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)的(de)(de)變(bian)化(hua)（延長）而(er)變(bian)化(hua)（逐(zhu)漸下降），通過(guo)全(quan)在(zai)(zai)(zai)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)(bei)進行(xing)自動電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)補(bu)償調整，保(bao)證(zheng)被測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)始終保(bao)持恒(heng)定的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)或(huo)恒(heng)定的(de)(de)功率進行(xing)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)終止(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、容量、時間(jian)和單體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)達到我們預(yu)(yu)期(qi)(qi)所設置的(de)(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)門(men)限(xian)值時，完成放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測(ce)試。實現該電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)(zu)(zu)在(zai)(zai)(zai)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)測(ce)試目的(de)(de)和預(yu)(yu)期(qi)(qi)維護效果。全(quan)在(zai)(zai)(zai)線(xian)(xian)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)工(gong)作原理，如(ru)圖3所示。

2.2在線放電“無縫連接”技術

為確保電(dian)池(chi)放電(dian)測試的(de)安全性，電(dian)池(chi)組全在線放電(dian)設備(bei)在串聯(lian)接(jie)進電(dian)池(chi)組正極時要求以無(wu)縫(feng)連接(jie)方式，如圖5所(suo)示(shi)。

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

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)方(fang)式(shi)能夠達到深度放(fang)電(dian)(dian)保持電(dian)(dian)池活性及(ji)檢測(ce)落后電(dian)(dian)池的放(fang)電(dian)(dian)測(ce)試目(mu)的，充分把(ba)握電(dian)(dian)池組剩余容(rong)量和(he)后備供電(dian)(dian)時間；
