電池檢測

UN38.3第八修(xiu)訂版與第七修(xiu)訂版之間的差異

1、鋰電池部分的試驗項(xiang)目、試驗要求及(ji)判定(ding)條件等均未發生變化(hua)。

2、UN38.3第八(ba)修訂版增加了鈉離(li)子電池的測(ce)試(shi)條款，具(ju)體測(ce)試(shi)項目(mu)的樣品(pin)數(shu)量及(ji)荷電狀(zhuang)態要(yao)求如下：

顯示功(gong)能(neng)測(ce)試(shi)(全檢(jian)(jian)(jian)):調節顯示器按(an)鈕，可查找到并正確(que)顯示電(dian)(dian)池(chi)(chi)組狀(zhuang)態信(xin)(xin)息。信(xin)(xin)息包 括(kuo):在線(xian)模式(FP on line / VRLA on line ) ，電(dian)(dian)池(chi)(chi)組電(dian)(dian)壓(ya)( Batteries V)，南京電(dian)(dian)池(chi)(chi)檢(jian)(jian)(jian)測(ce)，電(dian)(dian)池(chi)(chi)組電(dian)(dian)流( Batteries I)， 運行(xing)狀(zhuang)態(Run_ State: Stop/Normal)， SOC 值，電(dian)(dian)池(chi)(chi)組單體電(dian)(dian)壓(ya)(Module Cell Voltage) ，電(dian)(dian)池(chi)(chi)檢(jian)(jian)(jian)測(ce)報告， 電(dian)(dian)池(chi)(chi)組電(dian)(dian)芯溫度(du)( Module Cell temperature) ，系統容量( Batteries Capacity)， 系統信(xin)(xin)息 ( Batteries Info)，告警信(xin)(xin)息( Batt- ies Alarm Info) ，電(dian)(dian)池(chi)(chi)檢(jian)(jian)(jian)測(ce)標準(zhun)，接(jie)觸器狀(zhuang)態( Contactor Status)，5.切(qie)(qie)換(huan)功(gong)能(neng)測(ce)試(shi)(此項目只做(zuo)1個(ge)完整測(ce)試(shi)):接(jie)通電(dian)(dian)路后以50A充電(dian)(dian)電(dian)(dian)流將(jiang)系統充滿電(dian)(dian)，擱置5分鐘后，再以50A放電(dian)(dian)電(dian)(dian)流進行(xing)放電(dian)(dian)，并記錄(lu)電(dian)(dian)池(chi)(chi)組切(qie)(qie)換(huan)狀(zhuang)態，切(qie)(qie)換(huan)狀(zhuang)態需符合(he)設計邏輯。

設計邏(luo)輯:充電(dian)時FP優先充電(dian)，FP 滿電(dian)后切(qie)換(huan)至(zhi)(zhi)(zhi)(zhi)VRLA充電(dian)，直(zhi)至(zhi)(zhi)(zhi)(zhi)VRLA充滿，后切(qie)換(huan)到(dao)FP在(zai)線放(fang)電(dian)時FP優先放(fang)電(dian)，當FP放(fang)電(dian)至(zhi)(zhi)(zhi)(zhi)SOC=20%時切(qie)換(huan)至(zhi)(zhi)(zhi)(zhi)VRLA放(fang)電(dian)，VRLA放(fang)電(dian)至(zhi)(zhi)(zhi)(zhi)保護切(qie)換(huan)到(dao)FP繼續(xu)放(fang)電(dian)，直(zhi)至(zhi)(zhi)(zhi)(zhi)保護。

1.電(dian)(dian)壓(ya)測(ce)(ce)(ce)試(shi)(全檢(jian)):控制盒 上電(dian)(dian)后測(ce)(ce)(ce)量(liang)(liang)其(qi)總正(zheng)總負(P+/P-) 電(dian)(dian)壓(ya)，通過(guo)校準(zhun)后臺使后臺顯示(shi)電(dian)(dian)壓(ya)值與測(ce)(ce)(ce)量(liang)(liang)值相(xiang)等.

2.電(dian)流(liu)測試(全(quan)檢(jian)):控制充電(dian)機(ji)分(fen)別輸出(chu)20A和100A的(de)電(dian)流(liu)值(zhi)，通過校準后(hou)臺使.后(hou)臺顯示電(dian)流(liu)值(zhi)與測量值(zhi)相(xiang)等。

3.繼電(dian)(dian)器功能測試(全檢):分 別在電(dian)(dian)池組處于充電(dian)(dian)和放電(dian)(dian)狀(zhuang)態，通后臺手動切換(huan)LI和VRLA繼電(dian)(dian)器，2個(ge)電(dian)(dian)池組充放電(dian)(dian)狀(zhuang)態需符(fu)合繼電(dian)(dian)器切換(huan)狀(zhuang)態。
