BMS測試(shi)(shi)的(de)(de)(de)(de)必(bi)要(yao)(yao)(yao)性及測試(shi)(shi)方法BMS是個功能特別復(fu)雜的(de)(de)(de)(de)電子設備(bei)(bei)。在其設計(ji)階段，需(xu)要(yao)(yao)(yao)對原型的(de)(de)(de)(de)功能進(jin)(jin)行(xing)(xing)驗證；在生(sheng)產(chan)階段，需(xu)要(yao)(yao)(yao)對產(chan)品的(de)(de)(de)(de)功能進(jin)(jin)行(xing)(xing)測試(shi)(shi)；如果設備(bei)(bei)出現故(gu)障(zhang)，需(xu)要(yao)(yao)(yao)進(jin)(jin)行(xing)(xing)檢修。在這(zhe)些階段都(dou)需(xu)要(yao)(yao)(yao)有對應的(de)(de)(de)(de)測試(shi)(shi)設備(bei)(bei)來支持(chi)。BMS的(de)(de)(de)(de)各項功能涉及到包括數據采集(ji)、數據通訊、過程控(kong)制等多(duo)種(zhong)技(ji)術，需(xu)要(yao)(yao)(yao)用ADC、DIO、PWM、CAN、繼電器(qi)等多(duo)種(zhong)端口和設備(bei)(bei)，功能和算法都(dou)比較(jiao)復(fu)雜。為了對這(zhe)些復(fu)雜的(de)(de)(de)(de)功能進(jin)(jin)行(xing)(xing)全(quan)方面的(de)(de)(de)(de)測試(shi)(shi)（很多(duo)情況還要(yao)(yao)(yao)進(jin)(jin)行(xing)(xing)性能測試(shi)(shi)和評(ping)估）。

具體功(gong)能(neng)組(zu)成如下：實時通(tong)信：在電(dian)(dian)池(chi)(chi)的工作(zuo)過程中，對電(dian)(dian)池(chi)(chi)的電(dian)(dian)壓、溫(wen)度(du)、工作(zuo)電(dian)(dian)流、電(dian)(dian)池(chi)(chi)電(dian)(dian)量等一系(xi)列電(dian)(dian)池(chi)(chi)相(xiang)關參(can)數進行實時監控(kong)或計算。電(dian)(dian)壓、溫(wen)度(du)檢測：通(tong)過BMS內部的測量傳感器，將單(dan)(dan)個電(dian)(dian)芯的電(dian)(dian)壓值、溫(wen)度(du)值進行采集。該(gai)系(xi)統(tong)(tong)主要(yao)由高精度(du)電(dian)(dian)池(chi)(chi)模(mo)擬(ni)(ni)器、溫(wen)度(du)模(mo)擬(ni)(ni)器、總電(dian)(dian)壓模(mo)擬(ni)(ni)單(dan)(dan)元(yuan)(yuan)、充放(fang)電(dian)(dian)電(dian)(dian)流模(mo)擬(ni)(ni)單(dan)(dan)元(yuan)(yuan)、溫(wen)度(du)模(mo)擬(ni)(ni)單(dan)(dan)元(yuan)(yuan)、絕緣電(dian)(dian)阻檢測單(dan)(dan)元(yuan)(yuan)、信號(hao)與開關量檢測單(dan)(dan)元(yuan)(yuan)、CAN通(tong)訊單(dan)(dan)元(yuan)(yuan)、軟件控(kong)制系(xi)統(tong)(tong)等組(zu)成。

均(jun)衡管(guan)理：根(gen)據均(jun)衡策(ce)略，bms測(ce)試平臺(tai)，將(jiang)一(yi)致(zhi)性較差的電(dian)(dian)池(chi)電(dian)(dian)量通過電(dian)(dian)量轉移(yi)(主動均(jun)衡)或直接通過電(dian)(dian)阻釋(shi)放電(dian)(dian)能的方式將(jiang)電(dian)(dian)池(chi)拉(la)到同(tong)一(yi)水平線(被動均(jun)衡)。另該(gai)系(xi)統(tong)集成度(du)高、應用(yong)(yong)覆蓋面廣(guang)，涵(han)蓋高精度(du)電(dian)(dian)池(chi)模擬器、溫(wen)度(du)模擬器、總電(dian)(dian)壓模擬單(dan)元(yuan)、充放電(dian)(dian)電(dian)(dian)流模擬單(dan)元(yuan)等(deng)各類(lei)軟(ruan)、硬件，可以有效(xiao)支持(chi)BMS各項研發、生產測(ce)試需求。實際狀態未知——這一(yi)點是致(zhi)命(ming)的。電(dian)(dian)池(chi)組(zu)中每個電(dian)(dian)池(chi)單(dan)體的電(dian)(dian)壓、溫(wen)度(du)、均(jun)衡電(dian)(dian)流等(deng)參數的設(she)定值(zhi)是未知的，用(yong)(yong)戶(hu)只能獲(huo)取到測(ce)量值(zhi)，無法比對。
