電(dian)壓、溫度檢(jian)測(ce)(ce)(ce)：通過BMS內部的(de)測(ce)(ce)(ce)量(liang)傳感器(qi)，將單(dan)個(ge)電(dian)芯的(de)電(dian)壓值(zhi)、溫度值(zhi)進行(xing)采集。可控性(xing)差——單(dan)體(ti)的(de)容量(liang)、內阻等重要參數都(dou)受(shou)到實物的(de)限定，bms測(ce)(ce)(ce)試(shi)(shi)廠家(jia)，沒有調(diao)整(zheng)(zheng)的(de)空間。受(shou)制于電(dian)池組裝(zhuang)配工(gong)藝等多(duo)方(fang)面因(yin)素影響，bms測(ce)(ce)(ce)試(shi)(shi)電(dian)源，也無法(fa)調(diao)整(zheng)(zheng)任意一(yi)個(ge)單(dan)體(ti)的(de)SOC等運行(xing)狀態。BMS測(ce)(ce)(ce)試(shi)(shi)系(xi)統(tong)均采用(yong)自主研發(fa)的(de)測(ce)(ce)(ce)試(shi)(shi)儀器(qi)搭(da)建(jian)而成，bms測(ce)(ce)(ce)試(shi)(shi)哪(na)家(jia)好，設備外(wai)形、通訊協議、通訊接(jie)口(kou)等都(dou)采用(yong)統(tong)一(yi)標準，無論(lun)是(shi)擴展性(xing)還是(shi)可維護性(xing)都(dou)非常高。

BMS的功能包括3個主要方面：對(dui)電(dian)(dian)(dian)(dian)池組的工(gong)作狀態的監測(ce)(ce)與(yu)管理——單體和電(dian)(dian)(dian)(dian)池組的電(dian)(dian)(dian)(dian)壓(ya)監測(ce)(ce)、電(dian)(dian)(dian)(dian)流監測(ce)(ce)、溫(wen)(wen)度監測(ce)(ce)、SOC估算，均衡控(kong)制等。另外(wai)隨(sui)著循環次(ci)數增加(jia)，電(dian)(dian)(dian)(dian)池組自身(shen)的狀態也會發生變化，存(cun)在安(an)全(quan)隱患——電(dian)(dian)(dian)(dian)池組是(shi)個儲存(cun)很大能量的裝置，bms測(ce)(ce)試，這種測(ce)(ce)試方式(shi)對(dui)操作人(ren)員的人(ren)身(shen)安(an)全(quan)存(cun)在威脅。該(gai)系統(tong)主要由高精度電(dian)(dian)(dian)(dian)池模(mo)(mo)擬器(qi)、溫(wen)(wen)度模(mo)(mo)擬器(qi)、總電(dian)(dian)(dian)(dian)壓(ya)模(mo)(mo)擬單元(yuan)、充放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流模(mo)(mo)擬單元(yuan)、溫(wen)(wen)度模(mo)(mo)擬單元(yuan)、絕緣電(dian)(dian)(dian)(dian)阻檢(jian)測(ce)(ce)單元(yuan)、信號與(yu)開關量檢(jian)測(ce)(ce)單元(yuan)、CAN通訊單元(yuan)、軟件控(kong)制系統(tong)等組成。

可控(kong)性差——單體(ti)的(de)(de)容量、內阻等重(zhong)要參數都受(shou)到實(shi)物的(de)(de)限定(ding)，沒(mei)有調整的(de)(de)空間。受(shou)制于電(dian)(dian)池(chi)組(zu)(zu)裝配工(gong)藝等多方面(mian)因素影響，也無法調整任意一個單體(ti)的(de)(de)SOC等運行狀(zhuang)態(tai)。BMS的(de)(de)功能包括3個主要方面(mian)：對電(dian)(dian)池(chi)組(zu)(zu)的(de)(de)工(gong)作狀(zhuang)態(tai)的(de)(de)監(jian)測(ce)(ce)與管理——單體(ti)和(he)電(dian)(dian)池(chi)組(zu)(zu)的(de)(de)電(dian)(dian)壓監(jian)測(ce)(ce)、電(dian)(dian)流(liu)監(jian)測(ce)(ce)、溫度(du)(du)監(jian)測(ce)(ce)、SOC估算，均衡控(kong)制等。基于電(dian)(dian)池(chi)組(zu)(zu)的(de)(de)測(ce)(ce)試和(he)驗證(zheng)。通過高精度(du)(du)的(de)(de)程(cheng)(cheng)(cheng)控(kong)電(dian)(dian)池(chi)模(mo)擬器來(lai)電(dian)(dian)池(chi)單體(ti)的(de)(de)電(dian)(dian)壓，并具有一定(ding)的(de)(de)電(dian)(dian)流(liu)輸出和(he)吸(xi)收(shou)能力，放電(dian)(dian)和(he)充電(dian)(dian)過程(cheng)(cheng)(cheng)，通過高精度(du)(du)的(de)(de)程(cheng)(cheng)(cheng)控(kong)電(dian)(dian)阻來(lai)各溫度(du)(du)傳感(gan)器。
