5)BMS
BMS:Batterymanagementsystem電池管(guan)理系統,可以看作是(shi)電池的“大腦(nao)”。主要由CMU和BMU組成
CMU:CellmonitorUnit單體監控單元(yuan),負(fu)責測量電(dian)(dian)池的電(dian)(dian)壓、電(dian)(dian)流和溫(wen)度等參數,同時還(huan)有(you)均(jun)衡等功能(neng)。(上(shang)圖的模組圖片右(you)端的綠色電(dian)(dian)路板即CMU)。當CMU測量到這些數據后,將數據通(tong)過(guo)前面講到的電(dian)(dian)池“神經網絡”傳送給BMU。
BMU:BatterymanagementUnit電池管(guan)理單元。
負責評估CMU傳送的數據(ju),如果數據(ju)異常,則對電(dian)池進行保(bao)護,發出降低電(dian)流的要求,或(huo)者切斷(duan)充放電(dian)通路,以(yi)避免(mian)電(dian)池超出許可的使用條件(jian),同時還對電(dian)池的電(dian)量(liang)、溫(wen)度進行管理。根據(ju)先(xian)前設計(ji)的控制(zhi)策略,判斷(duan)需要警(jing)示的參數和狀(zhuang)態(tai),并且將警(jing)示發給整(zheng)車控制(zhi)器,**終(zhong)傳達給駕(jia)駛(shi)人員。
