BMS測試(shi)(shi)(shi)(shi)(shi)(shi)簡介：測試(shi)(shi)(shi)(shi)(shi)(shi)系(xi)(xi)統集(ji)高精度(du)(du)數據采(cai)集(ji)與控制于一體，實(shi)現BMS功(gong)能測試(shi)(shi)(shi)(shi)(shi)(shi)、充電模擬、溫度(du)(du)模擬等功(gong)能，滿足BMS研發人員對單項測試(shi)(shi)(shi)(shi)(shi)(shi)以及全功(gong)能自動化的(de)(de)測試(shi)(shi)(shi)(shi)(shi)(shi)需求。測試(shi)(shi)(shi)(shi)(shi)(shi)系(xi)(xi)統廣(guang)泛應用于研發功(gong)能測試(shi)(shi)(shi)(shi)(shi)(shi)、BMS量產(chan)EOL測試(shi)(shi)(shi)(shi)(shi)(shi)、BMS系(xi)(xi)統可(ke)靠性測試(shi)(shi)(shi)(shi)(shi)(shi)等應用。指標(biao)：◎實(shi)現BMS的(de)(de)各項功(gong)能驗證，覆(fu)蓋幾(ji)十種測試(shi)(shi)(shi)(shi)(shi)(shi)項目◎高精度(du)(du)高穩定性測試(shi)(shi)(shi)(shi)(shi)(shi)◎可(ke)構建BMS所需要的(de)(de)各類輸入/輸出(chu)信號(hao)◎可(ke)以模擬/采(cai)集(ji)BMS的(de)(de)內部(bu)(bu)和外部(bu)(bu)信號(hao)。

電壓(ya)(ya)、溫度檢測(ce)：通(tong)(tong)過BMS內(nei)部的(de)測(ce)量傳(chuan)感器，將單個(ge)電芯的(de)電壓(ya)(ya)值、溫度值進行(xing)采集。可控性差——單體的(de)容(rong)量、內(nei)阻(zu)等(deng)重要參數都受到實物的(de)限定，沒(mei)有調(diao)整的(de)空間。受制于電池(chi)組裝配工藝等(deng)多(duo)方面因(yin)素影響，也(ye)無(wu)法調(diao)整任意(yi)一個(ge)單體的(de)SOC等(deng)運行(xing)狀態。BMS測(ce)試系統均采用自主研發的(de)測(ce)試儀器搭建而成，設(she)備外形、通(tong)(tong)訊協議、通(tong)(tong)訊接(jie)口等(deng)都采用統一標準，無(wu)論是擴展性還是可維護性都非常高。

BMS的(de)(de)功能包(bao)括(kuo)3個主要(yao)方面：對電(dian)(dian)(dian)(dian)池組(zu)的(de)(de)工作狀態的(de)(de)監(jian)測(ce)(ce)(ce)(ce)(ce)與管理——單(dan)體和(he)電(dian)(dian)(dian)(dian)池組(zu)的(de)(de)電(dian)(dian)(dian)(dian)壓監(jian)測(ce)(ce)(ce)(ce)(ce)、電(dian)(dian)(dian)(dian)流(liu)監(jian)測(ce)(ce)(ce)(ce)(ce)、溫度監(jian)測(ce)(ce)(ce)(ce)(ce)、SOC估(gu)算，bms測(ce)(ce)(ce)(ce)(ce)試系(xi)統，均衡控制等。另(ling)外隨著循(xun)環次數增(zeng)加，電(dian)(dian)(dian)(dian)池組(zu)自身(shen)的(de)(de)狀態也(ye)會(hui)發生變化，存(cun)在安全(quan)隱患——電(dian)(dian)(dian)(dian)池組(zu)是個儲存(cun)很(hen)大(da)能量的(de)(de)裝置，這種測(ce)(ce)(ce)(ce)(ce)試方式(shi)對操(cao)作人員的(de)(de)人身(shen)安全(quan)存(cun)在威脅。該系(xi)統主要(yao)由高精度電(dian)(dian)(dian)(dian)池模(mo)擬器、溫度模(mo)擬器、總電(dian)(dian)(dian)(dian)壓模(mo)擬單(dan)元(yuan)、充放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)模(mo)擬單(dan)元(yuan)、溫度模(mo)擬單(dan)元(yuan)、絕緣電(dian)(dian)(dian)(dian)阻檢測(ce)(ce)(ce)(ce)(ce)單(dan)元(yuan)、信(xin)號與開關量檢測(ce)(ce)(ce)(ce)(ce)單(dan)元(yuan)、CAN通訊單(dan)元(yuan)、軟(ruan)件控制系(xi)統等組(zu)成。
