二、電池管理系統的英文縮寫為什么

電池(chi)(chi)管理系統的(de)英文縮(suo)寫是BMS，它是英文BATTERY MANAGEMENT SYSTEM的(de)首(shou)字(zi)母(mu)縮(suo)寫，翻譯過來就是電池(chi)(chi)管理系統。隨著新能源(yuan)電動汽車的(de)廣泛應(ying)用，電池(chi)(chi)的(de)容量(liang)、安(an)全性、健康狀(zhuang)態與續(xu)航能力日益成(cheng)為關注重(zhong)點，電池(chi)(chi)管理系統通(tong)過對電池(chi)(chi)進行監控與控制，可以將采(cai)集(ji)的(de)電池(chi)(chi)信息實(shi)時(shi)(shi)反饋(kui)給用戶，同時(shi)(shi)根據采(cai)集(ji)的(de)信息調節參數(shu)，充分(fen)發揮(hui)電池(chi)(chi)的(de)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。
