二、電池管理系統的英文縮寫為什么

電池(chi)管理(li)系統的英文(wen)縮寫是(shi)BMS，它是(shi)英文(wen)BATTERY MANAGEMENT SYSTEM的首字(zi)母縮寫，翻譯(yi)過來就是(shi)電池(chi)管理(li)系統。隨著新能源電動(dong)汽車的廣泛應(ying)用，電池(chi)的容量、安全性、健康狀態(tai)與續航(hang)能力日益成(cheng)為關注重點(dian)，電池(chi)管理(li)系統通過對電池(chi)進行監(jian)控與控制，可以將采集的電池(chi)信息實(shi)時(shi)反饋給用戶(hu)，同時(shi)根(gen)據采集的信息調(diao)節參數，充分發揮電池(chi)的性能。

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。
