二、電池管理系統的英文縮寫為什么

電(dian)(dian)(dian)池(chi)(chi)管理系統的(de)英文縮寫(xie)是BMS，它是英文BATTERY MANAGEMENT SYSTEM的(de)首字(zi)母(mu)縮寫(xie)，翻譯過來(lai)就是電(dian)(dian)(dian)池(chi)(chi)管理系統。隨著(zhu)新能源(yuan)電(dian)(dian)(dian)動(dong)汽車的(de)廣(guang)泛應用，電(dian)(dian)(dian)池(chi)(chi)的(de)容量、安全性(xing)(xing)、健康狀態與(yu)續航能力(li)日益成為(wei)關注重點，電(dian)(dian)(dian)池(chi)(chi)管理系統通過對電(dian)(dian)(dian)池(chi)(chi)進行(xing)監控與(yu)控制，可以將采(cai)集的(de)電(dian)(dian)(dian)池(chi)(chi)信息(xi)(xi)實時反饋(kui)給用戶(hu)，同時根據(ju)采(cai)集的(de)信息(xi)(xi)調節參數(shu)，充分發揮電(dian)(dian)(dian)池(chi)(chi)的(de)性(xing)(xing)能。

三、電池管理系統開發流程

1、電池管理系統開發的前期工作：電池管理系統的開發過程是從“確定BMS的拓撲結構”、“確定BMS的各項功能”、“動力電池特性測試”這三項工作開始的。2、電池管理系統軟硬件設計及實現：軟硬件設計及其實現是電池管理系統開發的主體工作，軟件的開發與硬件的開發工作是相輔相成的，即進行軟件開發的時候需要兼顧到各部分硬件的可執行為，而進行硬件設計的時候需要充分考慮到軟件算法復雜度。3、BMS單元測試及動力電池組整體測試：在完成電池管理系統硬件設計、制作以及軟件系統的編程、調試以后，所制訂的電池管理系統的各項基本功能就可以實現了。接下來需要做的就是大量的測試工作，其中包含BMS本身的單元測試以及整個動力電池組的整體測試。電池管理系統是一個比較復雜的系統，對開發要求較高，好的電池管理系統通常是專業的電池管理系統廠家開發出來的。
