對電(dian)(dian)(dian)池(chi)組(zu)異常狀態(tai)的(de)(de)(de)管(guan)理——單(dan)體(ti)和電(dian)(dian)(dian)池(chi)組(zu)的(de)(de)(de)過充、過放、過流(liu)(liu)、溫度超(chao)限、失衡等，對電(dian)(dian)(dian)池(chi)組(zu)故障(zhang)的(de)(de)(de)管(guan)理——傳感(gan)器丟失、單(dan)體(ti)故障(zhang)等。電(dian)(dian)(dian)池(chi)廠家(jia)(jia)(jia)或BMS廠家(jia)(jia)(jia)對BMS的(de)(de)(de)研究投入巨大(da)，bms測試哪家(jia)(jia)(jia)好，也是電(dian)(dian)(dian)池(chi)包提升續航(hang)里程(cheng)及穩定(ding)性的(de)(de)(de)關鍵因素(su)。實際狀態(tai)未(wei)知——這(zhe)一點是致命(ming)的(de)(de)(de)。電(dian)(dian)(dian)池(chi)組(zu)中每個電(dian)(dian)(dian)池(chi)單(dan)體(ti)的(de)(de)(de)電(dian)(dian)(dian)壓、溫度、均衡電(dian)(dian)(dian)流(liu)(liu)等參數(shu)的(de)(de)(de)設定(ding)值是未(wei)知的(de)(de)(de)，用戶只能獲取到(dao)測量值，無法比對。

BMS常見(jian)故障(zhang)(zhang)分析1、BMS與ECU通(tong)信(xin)不(bu)穩定(ding)可能原因:外部CAN總(zong)線(xian)(xian)匹配(pei)不(bu)良、總(zong)線(xian)(xian)分支(zhi)(zhi)過長(chang)故障(zhang)(zhang)排除:檢(jian)測(ce)總(zong)線(xian)(xian)匹配(pei)電(dian)(dian)阻(zu)是(shi)(shi)否(fou)(fou)正(zheng)確；匹配(pei)位(wei)置是(shi)(shi)否(fou)(fou)正(zheng)確，分支(zhi)(zhi)是(shi)(shi)否(fou)(fou)過長(chang)。2、BMS內(nei)部通(tong)信(xin)不(bu)穩定(ding)可能原因:通(tong)信(xin)線(xian)(xian)插頭松動、CAN走線(xian)(xian)不(bu)規范、BSU地址(zhi)有重(zhong)復(fu)(fu)。故障(zhang)(zhang)排除:檢(jian)測(ce)接(jie)線(xian)(xian)是(shi)(shi)否(fou)(fou)松動；檢(jian)測(ce)總(zong)線(xian)(xian)匹配(pei)電(dian)(dian)阻(zu)是(shi)(shi)否(fou)(fou)正(zheng)確，匹配(pei)位(wei)置是(shi)(shi)否(fou)(fou)正(zheng)確，分支(zhi)(zhi)是(shi)(shi)否(fou)(fou)過長(chang)；檢(jian)查BSU地址(zhi)是(shi)(shi)否(fou)(fou)重(zhong)復(fu)(fu)。

具體(ti)測(ce)試系(xi)統采用(yong)如(ru)下(xia)架構，bms測(ce)試電(dian)(dian)(dian)源，針對(dui)(dui)BMS的(de)(de)各項功(gong)能(neng)，bms測(ce)試，采用(yong)針對(dui)(dui)性的(de)(de)儀器進行(xing)(xing)數據模擬，用(yong)來測(ce)試BMS是(shi)否能(neng)按計劃(hua)設計的(de)(de)要求進行(xing)(xing)工(gong)作。另外(wai)隨著循環(huan)次(ci)數增加，電(dian)(dian)(dian)池組自身的(de)(de)狀態也會發生變化，存(cun)在安全隱患(huan)——電(dian)(dian)(dian)池組是(shi)個(ge)儲存(cun)很(hen)大能(neng)量的(de)(de)裝置，這種測(ce)試方式對(dui)(dui)操(cao)作人(ren)員的(de)(de)人(ren)身安全存(cun)在威脅。充放(fang)(fang)電(dian)(dian)(dian)管理：通過充放(fang)(fang)電(dian)(dian)(dian)策(ce)略(lve)根據采集到(dao)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)和溫度采用(yong)不同的(de)(de)工(gong)作狀態設置電(dian)(dian)(dian)池的(de)(de)佳充電(dian)(dian)(dian)或放(fang)(fang)電(dian)(dian)(dian)曲線（如(ru)充電(dian)(dian)(dian)電(dian)(dian)(dian)流，充電(dian)(dian)(dian)上限電(dian)(dian)(dian)壓(ya)(ya)值，放(fang)(fang)電(dian)(dian)(dian)下(xia)限電(dian)(dian)(dian)壓(ya)(ya)值等）。
