那么(me)，蓄(xu)電池(chi)放電檢測儀的(de)工作原(yuan)理(li)是(shi)是(shi)什么(me)呢？

蓄(xu)電(dian)(dian)(dian)(dian)(dian)池放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)檢測儀(yi)通過內置(zhi)電(dian)(dian)(dian)(dian)(dian)子負載對電(dian)(dian)(dian)(dian)(dian)池組實(shi)際進行放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。在放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)過程中，測試(shi)儀(yi)對蓄(xu)電(dian)(dian)(dian)(dian)(dian)池總電(dian)(dian)(dian)(dian)(dian)壓(ya)、放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流、溫度(du)實(shi)時自動(dong)掃描(miao)，當(dang)實(shi)際放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流值與所預設放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流值發(fa)生(sheng)偏差(cha)時，測試(shi)儀(yi)能閉環調控放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，保持恒(heng)流放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。測試(shi)儀(yi)根據預設參數，并考慮到(dao)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)率等因素，依據容量計(ji)(ji)算公(gong)式“潘克特公(gong)式”實(shi)時計(ji)(ji)算累加，測知蓄(xu)電(dian)(dian)(dian)(dian)(dian)池的實(shi)際放(fang)(fang)(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)量。

在(zai)測(ce)試(shi)(shi)儀(yi)放(fang)電(dian)(dian)(dian)(dian)(dian)測(ce)試(shi)(shi)過程中，如電(dian)(dian)(dian)(dian)(dian)池組電(dian)(dian)(dian)(dian)(dian)壓下降至預設(she)告警電(dian)(dian)(dian)(dian)(dian)壓值(zhi)時，測(ce)試(shi)(shi)儀(yi)報警并提示你檢(jian)查單(dan)體(ti)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓。此時，電(dian)(dian)(dian)(dian)(dian)壓值(zhi)低于額定標準值(zhi)85%（或自定標準值(zhi)）的(de)單(dan)體(ti)電(dian)(dian)(dian)(dian)(dian)池為不(bu)合格(ge)電(dian)(dian)(dian)(dian)(dian)池（信息(xi)產業部(bu)規定實際容量值(zhi)低于80%的(de)電(dian)(dian)(dian)(dian)(dian)池組必須停止使用(yong)），15分鐘內無任何操作測(ce)試(shi)(shi)儀(yi)將(jiang)自動停機。

蓄電(dian)池容(rong)(rong)量測試計(ji)算因式，需將各種溫度變化時的(de)(de)容(rong)(rong)量換(huan)算為25℃時的(de)(de)容(rong)(rong)量，才能標示其(qi)實(shi)際(ji)容(rong)(rong)量。同時，計(ji)算加(jia)式中的(de)(de)實(shi)際(ji)放電(dian)電(dian)流（a），實(shi)際(ji)放電(dian)時間（h），10h放電(dian)時間均為實(shi)時檢測值(zhi)。

那么，蓄電(dian)池放(fang)電(dian)檢測儀(yi)有(you)哪些(xie)功能呢？

功能一(yi)：核對性放電實(shi)驗

能夠(gou)對(dui)蓄電(dian)池組進行核對(dui)性容量測(ce)(ce)試，可以連續設(she)(she)定(ding)放電(dian)電(dian)流(liu)，按照設(she)(she)定(ding)的放電(dian)電(dian)流(liu)恒流(liu)放電(dian)，監測(ce)(ce)放電(dian)過程中(zhong)電(dian)池組的電(dian)壓(ya)，測(ce)(ce)量電(dian)池組的容量。

多種放電停止條(tiao)件的設定：

Ø電池組總電壓(ya)

Ø放(fang)電時間

Ø放(fang)電容量

Ø可適應(ying)多種(zhong)電池電壓：2V、4V、6V、12V

任意條(tiao)件達到時，儀器便(bian)自動終止測試，避(bi)免(mian)過度放電對電池造(zao)成(cheng)損傷。

功(gong)能(neng)二：短時容量測試功(gong)能(neng)

(1)在核(he)對性放(fang)電(dian)之(zhi)后(hou)無需拆卸設備(bei)及可對之(zhi)后(hou)蓄電(dian)池組的(de)充電(dian)過(guo)程進行全程監(jian)測,包(bao)括:

整組充電電壓

單體充電電壓

充電時間

(2)可(ke)實時在線監(jian)測電(dian)池組(zu)每節(jie)電(dian)池的電(dian)壓變化(hua)情(qing)況并記錄(lu)下來(lai),通過后臺軟件可(ke)查看相應數據,挑選(xuan)出落后蓄(xu)電(dian)池并打印報表。

功(gong)能三：短時容量(liang)測試功(gong)能

本設備可采用(yong)(yong)10~20分鐘的快速(su)放電(dian)，用(yong)(yong)于快速(su)測試電(dian)池放電(dian)能力，快速(su)判(pan)斷(duan)電(dian)池的性(xing)能及容量。

功能四：電流監測(ce)功能（選配）

停電(dian)時/實際(ji)負載放(fang)電(dian)時，在(zai)線自動監測單體(ti)電(dian)池(chi)電(dian)壓，電(dian)池(chi)組電(dian)壓及放(fang)電(dian)電(dian)流，記(ji)錄電(dian)池(chi)的放(fang)電(dian)容(rong)量，保證(zheng)對電(dian)池(chi)狀態的判斷。

功能(neng)五：無線數據傳輸功能(neng)

1、單體電池電壓用過無線傳(chuan)輸方式進行數據傳(chuan)輸，省去了接(jie)線的麻煩。

2、電(dian)(dian)池組總(zong)電(dian)(dian)壓(ya)采用無(wu)線傳(chuan)(chuan)輸方(fang)式進行數據(ju)傳(chuan)(chuan)輸。

3、放電過(guo)(guo)程監測(ce)，使(shi)用無線通訊(xun)終端講電池放電數據實時(shi)傳送到(dao)計算機管理軟件，可實時(shi)查看放電過(guo)(guo)程數據并(bing)自動(dong)保存。

功(gong)能(neng)(neng)六：落后電池識別功(gong)能(neng)(neng)（接續放電功(gong)能(neng)(neng)）

在放(fang)電(dian)(dian)過(guo)程中當某一節(jie)電(dian)(dian)池(chi)達到放(fang)電(dian)(dian)下(xia)(xia)限(xian)閥值而整組電(dian)(dian)壓(ya)還(huan)處于正常(chang)電(dian)(dian)壓(ya)時(shi)可選擇暫停放(fang)電(dian)(dian)，將落后電(dian)(dian)池(chi)提(ti)(ti)出(chu)后繼續放(fang)電(dian)(dian)，以(yi)免(mian)將次電(dian)(dian)池(chi)過(guo)放(fang)，對日后針(zhen)對該節(jie)電(dian)(dian)池(chi)進行活化提(ti)(ti)供科(ke)學的(de)條件。該功能可以(yi)挑出(chu)前(qian)6節(jie)達到下(xia)(xia)限(xian)閥值的(de)電(dian)(dian)池(chi)，因為(wei)一旦超過(guo)6節(jie)即任務整組電(dian)(dian)池(chi)不達標。

接續放(fang)電功能(neng)還可(ke)以(yi)講放(fang)電工(gong)(gong)作(zuo)分(fen)不(bu)同工(gong)(gong)作(zuo)日(ri)進行，以(yi)方便工(gong)(gong)作(zuo)人員的(de)時間安排。

功能七(qi)：數據管理功能

完善的計(ji)算機(ji)管理分析(xi)監控軟件，具有強大的數(shu)據處理功(gong)能，采用*數(shu)學模型(xing)，對(dui)電池的多項測量結果(guo)進行綜合(he)分析(xi)，準(zhun)確(que)判(pan)斷(duan)電池性能，并可查詢電池的實時運行狀態及(ji)歷史數(shu)據，包括各項參數(shu)、曲線并自動生成(cheng)報表。
