蓄電池測試儀使用方法

蓄電(dian)(dian)池測試儀通常有傳(chuan)統測試和電(dian)(dian)導儀測試兩種方法。

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)(de)(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)都是蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)，蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)最(zui)大(da)的(de)(de)(de)(de)(de)(de)特點(dian)(dian)就是隨著蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)(de)使(shi)用(yong)，蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)逐漸老化，當蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)降低到他原(yuan)本額定(ding)容(rong)量(liang)的(de)(de)(de)(de)(de)(de)80%的(de)(de)(de)(de)(de)(de)時候，蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)(de)容(rong)量(liang)可能(neng)呈“跳水(shui)式(shi)”下降，這時盡管該蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)可能(neng)仍(reng)然能(neng)夠提供一定(ding)的(de)(de)(de)(de)(de)(de)能(neng)量(liang)，但隨時可能(neng)報(bao)廢。在國(guo)際國(guo)內的(de)(de)(de)(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)行業，都把80%的(de)(de)(de)(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)作為蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)(de)一個臨界點(dian)(dian)，當蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)降低到其原(yuan)額定(ding)容(rong)量(liang)的(de)(de)(de)(de)(de)(de)80%的(de)(de)(de)(de)(de)(de)時候，這個蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)就需要(yao)更換了。

2、傳統辦法健康的判定

判定(ding)(ding)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)健(jian)康(kang)狀(zhuang)況的(de)(de)傳統辦法(fa)就(jiu)是放(fang)電(dian)(dian)(dian)(dian)(dian)方式，一般通過放(fang)電(dian)(dian)(dian)(dian)(dian)來(lai)測試蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)目前的(de)(de)實際容量(liang)，從(cong)而判定(ding)(ding)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)健(jian)康(kang)狀(zhuang)況。對于汽車(che)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)來(lai)說(shuo)，國際蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)協會(hui)（BCI）規(gui)定(ding)(ding)，在常溫下以1/2的(de)(de)額定(ding)(ding)冷起動(dong)電(dian)(dian)(dian)(dian)(dian)流(liu)值進行放(fang)電(dian)(dian)(dian)(dian)(dian)15秒，如果蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓為(wei)9.6V以上，這個蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就(jiu)通過了放(fang)電(dian)(dian)(dian)(dian)(dian)實驗，是個健(jian)康(kang)的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。

3、傳統檢測不足的表現

傳統(tong)的方法以外加負載來測(ce)試蓄電池(chi)，其(qi)手段(duan)不足有以下表(biao)現：

（1）被測試(shi)的蓄電池必須滿充，至少有12.4V，由(you)于測試(shi)原理是放電，如果測試(shi)對象(xiang)已經部(bu)分(fen)放電，必然導(dao)致測量的結果電壓值偏低而造成誤(wu)判；

（2）對于(yu)同(tong)一個蓄(xu)(xu)電(dian)池，無法連續重復測(ce)量(liang)，得到相同(tong)的(de)(de)(de)的(de)(de)(de)結果。由于(yu)測(ce)試過(guo)程(cheng)就是放電(dian)過(guo)程(cheng)，被測(ce)試的(de)(de)(de)蓄(xu)(xu)電(dian)池在測(ce)試后，必須重新充電(dian)，才能再次測(ce)量(liang)；

（3）測(ce)試(shi)過(guo)程發出大量的(de)熱，無法(fa)連續測(ce)試(shi)多個的(de)蓄電池；

（4）測(ce)試(shi)過程要求測(ce)試(shi)者訓練有素(su)，由于(yu)必須在放電(dian)15秒的(de)瞬間讀(du)出蓄電(dian)池的(de)電(dian)壓值，操作者的(de)水平和(he)責任心(xin)都會對測(ce)試(shi)結論產(chan)生(sheng)影響。

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>>

由于許多(duo)的汽車維修網點缺(que)乏高效的測(ce)試(shi)(shi)工具，未能在車主遇上問題前及時發現已經衰弱的蓄(xu)(xu)電(dian)池(chi)(chi)，從而(er)喪失了(le)潛在的銷(xiao)售蓄(xu)(xu)電(dian)池(chi)(chi)的機會。傳統(tong)使(shi)用的比重指示、端電(dian)壓等測(ce)試(shi)(shi)手(shou)段反映的都是蓄(xu)(xu)電(dian)池(chi)(chi)的充電(dian)情況(kuang)（SOC），而(er)非健(jian)康情況(kuang)（SOJ），無法(fa)作為檢驗(yan)蓄(xu)(xu)電(dian)池(chi)(chi)是否需(xu)要更(geng)換的有(you)效方法(fa)。

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)(ji)上大量(liang)(liang)的(de)實驗數(shu)據(ju)表(biao)明，電(dian)(dian)(dian)(dian)導值(zhi)與蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)呈很好(hao)的(de)線形關系。對于同一種蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)，隨著(zhu)(zhu)使(shi)用(yong)后蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)容量(liang)(liang)的(de)下降，該蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)導值(zhi)也會下降，這(zhe)樣的(de)一個線形關系正(zheng)(zheng)是電(dian)(dian)(dian)(dian)導儀能夠(gou)正(zheng)(zheng)確(que)判定蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)健康情況的(de)基(ji)礎。正(zheng)(zheng)因為如(ru)此(ci)，國際(ji)(ji)電(dian)(dian)(dian)(dian)氣(qi)和電(dian)(dian)(dian)(dian)子(zi)工(gong)程師協會（IEEE）正(zheng)(zheng)式把電(dian)(dian)(dian)(dian)導測(ce)(ce)試(shi)法作為測(ce)(ce)試(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)測(ce)(ce)試(shi)標(biao)準之一，在(zai)IEEE標(biao)準1118-1996的(de)第15頁，明確(que)指出(chu)，蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)導的(de)測(ce)(ce)量(liang)(liang)是將(jiang)已知頻率和振幅的(de)交(jiao)流電(dian)(dian)(dian)(dian)壓加到蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)兩端，然(ran)后測(ce)(ce)量(liang)(liang)所產生的(de)電(dian)(dian)(dian)(dian)流。交(jiao)流電(dian)(dian)(dian)(dian)導值(zhi)就是與交(jiao)流電(dian)(dian)(dian)(dian)壓同相(xiang)的(de)交(jiao)流電(dian)(dian)(dian)(dian)流分量(liang)(liang)與交(jiao)流電(dian)(dian)(dian)(dian)壓的(de)比值(zhi)，明顯(xian)的(de)電(dian)(dian)(dian)(dian)導值(zhi)的(de)變(bian)化（下降大于20%）就意味著(zhu)(zhu)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)性能的(de)變(bian)化。

2、電導測試儀的工作原理

蓄(xu)(xu)電(dian)(dian)(dian)池(chi)隨著使(shi)用(yong)時間的(de)(de)(de)增加，會逐漸老化(hua)(hua)(hua)，其老化(hua)(hua)(hua)的(de)(de)(de)主要(yao)(yao)原因正是(shi)(shi)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)極表(biao)面發生硫化(hua)(hua)(hua)、腐蝕，活性(xing)(xing)(xing)材料脫(tuo)落，無法再進(jin)(jin)行(xing)有效的(de)(de)(de)化(hua)(hua)(hua)學(xue)反應，這是(shi)(shi)絕大部分蓄(xu)(xu)電(dian)(dian)(dian)池(chi)無法繼續(xu)使(shi)用(yong)的(de)(de)(de)主要(yao)(yao)原因。電(dian)(dian)(dian)導儀(yi)的(de)(de)(de)工(gong)作原理就是(shi)(shi)通(tong)過測(ce)(ce)(ce)量極板(ban)表(biao)面的(de)(de)(de)情況，判定(ding)其化(hua)(hua)(hua)學(xue)反應能力，并通(tong)過極板(ban)的(de)(de)(de)變化(hua)(hua)(hua)來推斷(duan)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)容量的(de)(de)(de)變化(hua)(hua)(hua)，從而判定(ding)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)的(de)(de)(de)健(jian)康狀況。電(dian)(dian)(dian)導儀(yi)所進(jin)(jin)行(xing)的(de)(de)(de)測(ce)(ce)(ce)試(shi)工(gong)作就是(shi)(shi)以蓄(xu)(xu)電(dian)(dian)(dian)池(chi)目前測(ce)(ce)(ce)得的(de)(de)(de)實際電(dian)(dian)(dian)導值(zhi)與蓄(xu)(xu)電(dian)(dian)(dian)池(chi)完好時的(de)(de)(de)標準電(dian)(dian)(dian)導值(zhi)進(jin)(jin)行(xing)比(bi)較，如果差異大到一定(ding)程度，就可以判定(ding)該(gai)蓄(xu)(xu)電(dian)(dian)(dian)池(chi)需要(yao)(yao)更換了。實踐證明，電(dian)(dian)(dian)導儀(yi)的(de)(de)(de)測(ce)(ce)(ce)試(shi)結果與用(yong)1/2的(de)(de)(de)CCA值(zhi)放電(dian)(dian)(dian)的(de)(de)(de)測(ce)(ce)(ce)試(shi)結果是(shi)(shi)吻(wen)合的(de)(de)(de)，充分說明了電(dian)(dian)(dian)導儀(yi)測(ce)(ce)(ce)試(shi)的(de)(de)(de)科學(xue)性(xing)(xing)(xing)、準確(que)性(xing)(xing)(xing)。

蓄電池測試儀的應用

1、蓄電池測試技術的發展

對(dui)于汽車蓄(xu)電(dian)池來(lai)說，冷起動電(dian)流(liu)是(shi)其最重(zhong)要的指標(biao)，以冷起動電(dian)流(liu)的單位進(jin)行顯示，為的是(shi)讓(rang)用(yong)戶(hu)使(shi)用(yong)起來(lai)更加直觀(guan)明了。電(dian)導儀(yi)在使(shi)用(yong)時，根據(ju)蓄(xu)電(dian)池的標(biao)注輸(shu)入其額定CCA值(zhi)，然(ran)后儀(yi)表會測出一(yi)個電(dian)導CCA值(zhi)，儀(yi)表正是(shi)通過兩個CCA值(zhi)差異(yi)的比(bi)較，對(dui)蓄(xu)電(dian)池的健康狀況進(jin)行判定，所以世界上絕大(da)多數國家對(dui)蓄(xu)電(dian)池的標(biao)注都是(shi)使(shi)用(yong)冷起動電(dian)流(liu)，近幾年國際(ji)業界基本(ben)都采取電(dian)導測試法。

國際(ji)電氣和電子工程(cheng)師(shi)協會(hui)（IEEE）標準1118-1996中的規定成為(wei)電導汽車蓄電池測試儀的測試原理和判斷依據(ju)。
