    摘要:

    為解決電動(dòng)汽車(chē)現有BMS系統對鋰離子動(dòng)力電池SOH評估與預測難以滿(mǎn)足多種工況條件、各種類(lèi)動(dòng)力電池,且難同時(shí)兼顧預測精度與反饋速度等應用缺陷,提出了一套全新的EVs電池健康管理系統設計思路,采用了結合云計算與存儲平臺,融入BMS評估體系等關(guān)鍵方法;通過(guò)BMS增加5G通訊模塊,利用5G/4G信號實(shí)時(shí)上傳電芯數據,經(jīng)過(guò)云平臺搭載的多種SOH評估模型與算法,多線(xiàn)程在線(xiàn)計算得到預測結果,及時(shí)反饋至用戶(hù)端和BMS,實(shí)現電池健康管理;該體系的設計案例展示出較好的未來(lái)應用價(jià)值,為電動(dòng)汽車(chē)電池管理設計提供了新方向。

    Abstract:

    To solve the electric vehicles battery management system(BMS) for lithium ion power battery state of health(SOH) assessment and prediction is difficult to meet a variety of working conditions, various types of power battery, and difficult to balance between accuracy and feedback speed applications such as defects, puts forward a new set of EVs battery health management system design idea, adopting the combination of cloud computing and storage platform, Integrate BMS evaluation system and other key methods; Add 5G communication module through BMS, use 5G/4G signal to upload cell data in real time, through a variety of SOH evaluation models and algorithms equipped with cloud platform, multi-thread online calculation to get the prediction results, timely feedback to the user and BMS, to achieve battery health management. The design case of this system shows good future application value and provides a new direction for EV battery management design.
