蓄電池測試儀是什么

蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測試(shi)儀，蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)單體活化(hua)儀是專(zhuan)用于日常維護中(zhong)對(dui)落后(hou)單體蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)處理的(de)便攜(xie)式產品，它具有三種(zhong)獨立(li)的(de)使用方(fang)(fang)式：電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)方(fang)(fang)式，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方(fang)(fang)式和電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)活化(hua)方(fang)(fang)式。可(ke)以針對(dui)不同(tong)落后(hou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)實際情況，對(dui)落后(hou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進行(xing)容量試(shi)驗，低壓恒流(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，或設置多個循環(huan)周期對(dui)最小(xiao)容量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)作循環(huan)多次充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，以激化(hua)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)極板(ban)失(shi)效的(de)活性物質使電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)活化(hua)，提升落后(hou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)容量。

蓄電(dian)池(chi)測(ce)試儀(yi)又稱(cheng)蓄電(dian)池(chi)檢(jian)測(ce)儀(yi)或蓄電(dian)池(chi)分析儀(yi)，是(shi)針對汽(qi)(qi)車(che)(che)(che)蓄電(dian)池(chi)的工作能力(li)判斷的專業分析檢(jian)測(ce)設備(bei)。汽(qi)(qi)車(che)(che)(che)蓄電(dian)池(chi)對于汽(qi)(qi)車(che)(che)(che)來說(shuo)，盡(jin)管在(zai)成本上(shang)所占(zhan)的比(bi)重不高(gao)，但它對整部(bu)汽(qi)(qi)車(che)(che)(che)卻起(qi)著舉足輕重的作用。所以，了解汽(qi)(qi)車(che)(che)(che)蓄電(dian)池(chi)是(shi)否(fou)仍(reng)然(ran)良(liang)好，提前更換將(jiang)要報廢(fei)的蓄電(dian)池(chi)，能有效提高(gao)企(qi)業的服務水(shui)平(ping)和用戶滿(man)意度，為(wei)蓄電(dian)池(chi)生(sheng)產企(qi)業、汽(qi)(qi)車(che)(che)(che)生(sheng)產線、汽(qi)(qi)車(che)(che)(che)維修企(qi)業和蓄電(dian)池(chi)經銷企(qi)業以及其他用戶在(zai)蓄電(dian)池(chi)的檢(jian)測(ce)工作中帶(dai)來極大(da)的便利。

蓄電池測試儀使用方法

蓄(xu)電池測(ce)試(shi)儀(yi)通常有傳統測(ce)試(shi)和電導儀(yi)測(ce)試(shi)兩種(zhong)方法。

傳統蓄電池測試方法

1、傳統蓄電池測試的依據

目前，世界上幾乎所有的汽車所用(yong)的(de)(de)蓄電(dian)(dian)池(chi)(chi)都是(shi)蓄電(dian)(dian)池(chi)(chi)，蓄電(dian)(dian)池(chi)(chi)最大的(de)(de)特點就是(shi)隨(sui)著蓄電(dian)(dian)池(chi)(chi)的(de)(de)使用(yong)，蓄電(dian)(dian)池(chi)(chi)逐(zhu)漸老(lao)化，當蓄電(dian)(dian)池(chi)(chi)容(rong)(rong)量(liang)(liang)(liang)降低(di)到他原(yuan)本額定(ding)容(rong)(rong)量(liang)(liang)(liang)的(de)(de)80%的(de)(de)時(shi)候，蓄電(dian)(dian)池(chi)(chi)的(de)(de)容(rong)(rong)量(liang)(liang)(liang)可能(neng)呈“跳水式”下降，這時(shi)盡管(guan)該(gai)蓄電(dian)(dian)池(chi)(chi)可能(neng)仍然能(neng)夠(gou)提供一定(ding)的(de)(de)能(neng)量(liang)(liang)(liang)，但隨(sui)時(shi)可能(neng)報廢。在國際(ji)國內的(de)(de)蓄電(dian)(dian)池(chi)(chi)行業，都把80%的(de)(de)蓄電(dian)(dian)池(chi)(chi)容(rong)(rong)量(liang)(liang)(liang)作為蓄電(dian)(dian)池(chi)(chi)的(de)(de)一個臨界點，當蓄電(dian)(dian)池(chi)(chi)容(rong)(rong)量(liang)(liang)(liang)降低(di)到其原(yuan)額定(ding)容(rong)(rong)量(liang)(liang)(liang)的(de)(de)80%的(de)(de)時(shi)候，這個蓄電(dian)(dian)池(chi)(chi)就需要更換了。

2、傳統辦法健康的判定

判(pan)定蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)健(jian)康(kang)狀(zhuang)況(kuang)的(de)傳統辦(ban)法就是放電(dian)(dian)(dian)(dian)(dian)(dian)方式，一般通(tong)過放電(dian)(dian)(dian)(dian)(dian)(dian)來(lai)(lai)測試(shi)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)目前的(de)實(shi)際容量，從而(er)判(pan)定蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)健(jian)康(kang)狀(zhuang)況(kuang)。對于汽(qi)車蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)來(lai)(lai)說，國際蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)協會(hui)（BCI）規定，在常(chang)溫下以(yi)1/2的(de)額定冷起動電(dian)(dian)(dian)(dian)(dian)(dian)流值(zhi)進(jin)行(xing)放電(dian)(dian)(dian)(dian)(dian)(dian)15秒，如(ru)果(guo)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)9.6V以(yi)上，這個蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)就通(tong)過了(le)放電(dian)(dian)(dian)(dian)(dian)(dian)實(shi)驗，是個健(jian)康(kang)的(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。

3、傳統檢測不足的表現

傳統(tong)的方法以外加負(fu)載來測試蓄電池，其手段不足有以下表現(xian)：

（1）被測(ce)(ce)試(shi)(shi)的蓄電(dian)(dian)池必須(xu)滿充，至少有12.4V，由于測(ce)(ce)試(shi)(shi)原(yuan)理是(shi)放電(dian)(dian)，如果(guo)測(ce)(ce)試(shi)(shi)對象已經部(bu)分(fen)放電(dian)(dian)，必然導致(zhi)測(ce)(ce)量(liang)的結(jie)果(guo)電(dian)(dian)壓值偏(pian)低而(er)造成誤判；

（2）對于同(tong)一個蓄(xu)電(dian)池，無法連(lian)續重(zhong)復測量，得到相同(tong)的的結果。由于測試(shi)過程就(jiu)是(shi)放電(dian)過程，被測試(shi)的蓄(xu)電(dian)池在測試(shi)后，必須重(zhong)新充電(dian)，才能再次測量；

（3）測試過程發出大(da)量的(de)熱，無法(fa)連(lian)續(xu)測試多個的(de)蓄電(dian)池(chi)；

（4）測(ce)(ce)試過程要求測(ce)(ce)試者(zhe)訓練(lian)有素，由于(yu)必須在(zai)放電15秒的瞬間讀(du)出蓄(xu)電池的電壓值，操作(zuo)者(zhe)的水平(ping)和責任心都會對測(ce)(ce)試結論產生影(ying)響。

4、傳統檢測造成的影響

正是由于傳統測試蓄電池手段不足的原因，蓄電池經銷商以及汽車維修站、汽車經銷商常常將好的蓄電池作為壞蓄電池退回給廠家，據美國最大的汽車蓄電池經銷商INTERSTATE統計，在退回來的所謂的壞蓄電池中，50%的蓄電池實際上是好的，這些蓄電池需要的是充電，而不是更換，這部分好蓄電池，只是因為失誤的判斷，無謂地往返于廠家和經銷商之間，白白造成彼此的耗費。汽車蓄電池怎么充電>>

由于許(xu)多的(de)(de)汽車維修網點(dian)缺乏高效(xiao)的(de)(de)測試工(gong)具，未(wei)能(neng)在(zai)車主(zhu)遇上問題前(qian)及時發現已經(jing)衰弱的(de)(de)蓄電(dian)(dian)池(chi)，從而喪失(shi)了潛在(zai)的(de)(de)銷(xiao)售蓄電(dian)(dian)池(chi)的(de)(de)機會。傳統(tong)使(shi)用的(de)(de)比重指示、端電(dian)(dian)壓等測試手段反映的(de)(de)都是蓄電(dian)(dian)池(chi)的(de)(de)充(chong)電(dian)(dian)情(qing)況（SOC），而非健康情(qing)況（SOJ），無法作為(wei)檢驗(yan)蓄電(dian)(dian)池(chi)是否需要更(geng)換的(de)(de)有效(xiao)方(fang)法。

電導蓄電池檢測原理

1、電導測試儀的技術原理

經過國際(ji)上大(da)量(liang)(liang)的(de)實驗數(shu)據表明，電(dian)(dian)(dian)導(dao)(dao)值(zhi)(zhi)與(yu)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)呈(cheng)很好的(de)線形(xing)關系(xi)。對于同一種蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)，隨著(zhu)使用(yong)后蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)的(de)下(xia)降，該(gai)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)導(dao)(dao)值(zhi)(zhi)也會(hui)(hui)下(xia)降，這樣的(de)一個線形(xing)關系(xi)正是(shi)電(dian)(dian)(dian)導(dao)(dao)儀能(neng)夠正確判定蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)健康情(qing)況(kuang)的(de)基(ji)礎。正因為如此(ci)，國際(ji)電(dian)(dian)(dian)氣和電(dian)(dian)(dian)子工程師協會(hui)(hui)（IEEE）正式把電(dian)(dian)(dian)導(dao)(dao)測試法作為測試蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)測試標準之(zhi)一，在IEEE標準1118-1996的(de)第(di)15頁，明確指出(chu)，蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)導(dao)(dao)的(de)測量(liang)(liang)是(shi)將(jiang)已知(zhi)頻率和振幅(fu)的(de)交(jiao)流(liu)電(dian)(dian)(dian)壓(ya)加到蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)兩(liang)端，然后測量(liang)(liang)所產(chan)生的(de)電(dian)(dian)(dian)流(liu)。交(jiao)流(liu)電(dian)(dian)(dian)導(dao)(dao)值(zhi)(zhi)就(jiu)是(shi)與(yu)交(jiao)流(liu)電(dian)(dian)(dian)壓(ya)同相的(de)交(jiao)流(liu)電(dian)(dian)(dian)流(liu)分量(liang)(liang)與(yu)交(jiao)流(liu)電(dian)(dian)(dian)壓(ya)的(de)比值(zhi)(zhi)，明顯的(de)電(dian)(dian)(dian)導(dao)(dao)值(zhi)(zhi)的(de)變化(hua)（下(xia)降大(da)于20%）就(jiu)意味著(zhu)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)(chi)性能(neng)的(de)變化(hua)。

2、電導測試儀的工作原理

蓄(xu)電(dian)(dian)(dian)池(chi)(chi)隨(sui)著使用(yong)(yong)時(shi)間(jian)的(de)(de)(de)(de)增加，會逐(zhu)漸老化(hua)，其(qi)老化(hua)的(de)(de)(de)(de)主要原(yuan)(yuan)因正是(shi)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)極表面發生硫(liu)化(hua)、腐蝕(shi)，活性材(cai)料脫(tuo)落，無法(fa)再進(jin)行有(you)效(xiao)的(de)(de)(de)(de)化(hua)學反應(ying)，這是(shi)絕大部分(fen)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)無法(fa)繼續(xu)使用(yong)(yong)的(de)(de)(de)(de)主要原(yuan)(yuan)因。電(dian)(dian)(dian)導(dao)(dao)儀的(de)(de)(de)(de)工作原(yuan)(yuan)理就(jiu)是(shi)通(tong)過測(ce)量極板表面的(de)(de)(de)(de)情況，判(pan)定其(qi)化(hua)學反應(ying)能力(li)，并通(tong)過極板的(de)(de)(de)(de)變(bian)化(hua)來推斷蓄(xu)電(dian)(dian)(dian)池(chi)(chi)容量的(de)(de)(de)(de)變(bian)化(hua)，從而判(pan)定蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)健康狀況。電(dian)(dian)(dian)導(dao)(dao)儀所(suo)進(jin)行的(de)(de)(de)(de)測(ce)試(shi)工作就(jiu)是(shi)以(yi)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)目(mu)前測(ce)得的(de)(de)(de)(de)實際電(dian)(dian)(dian)導(dao)(dao)值(zhi)與(yu)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)完好(hao)時(shi)的(de)(de)(de)(de)標準電(dian)(dian)(dian)導(dao)(dao)值(zhi)進(jin)行比較，如果差異大到一定程(cheng)度(du)，就(jiu)可以(yi)判(pan)定該蓄(xu)電(dian)(dian)(dian)池(chi)(chi)需要更換(huan)了。實踐證明，電(dian)(dian)(dian)導(dao)(dao)儀的(de)(de)(de)(de)測(ce)試(shi)結果與(yu)用(yong)(yong)1/2的(de)(de)(de)(de)CCA值(zhi)放電(dian)(dian)(dian)的(de)(de)(de)(de)測(ce)試(shi)結果是(shi)吻合的(de)(de)(de)(de)，充分(fen)說明了電(dian)(dian)(dian)導(dao)(dao)儀測(ce)試(shi)的(de)(de)(de)(de)科學性、準確性。

蓄電池測試儀的應用

1、蓄電池測試技術的發展

對于汽車蓄電(dian)池(chi)來(lai)說，冷起動電(dian)流是(shi)(shi)其最重(zhong)要的指標(biao)(biao)，以冷起動電(dian)流的單位(wei)進行顯示，為的是(shi)(shi)讓(rang)用戶(hu)使(shi)用起來(lai)更加直觀明了。電(dian)導(dao)儀(yi)在使(shi)用時，根據(ju)蓄電(dian)池(chi)的標(biao)(biao)注輸(shu)入其額定(ding)(ding)CCA值(zhi)，然后儀(yi)表會測出一(yi)個電(dian)導(dao)CCA值(zhi)，儀(yi)表正是(shi)(shi)通過兩個CCA值(zhi)差異的比較，對蓄電(dian)池(chi)的健康狀況進行判定(ding)(ding)，所以世界(jie)上絕大多數國(guo)家對蓄電(dian)池(chi)的標(biao)(biao)注都是(shi)(shi)使(shi)用冷起動電(dian)流，近幾(ji)年國(guo)際業界(jie)基本都采取電(dian)導(dao)測試法。

國際電氣和電子工程師協會（IEEE）標準1118-1996中的規(gui)定成為電導(dao)汽車(che)蓄(xu)電池測試(shi)儀的測試(shi)原理和判斷依據。
