摘要：通過分析蓄電池運(yùn)常見的現(xiàn)象電池失效模式和內(nèi)阻的關(guān)系，研究了蓄電池在線監(jiān)測(cè)管理系統(tǒng)應(yīng)解決的關(guān)鍵問題，主要包括：1)監(jiān)測(cè)管理系統(tǒng)的合理結(jié)構(gòu)，2)電池單體的內(nèi)阻數(shù)據(jù)在蓄電池監(jiān)測(cè)系統(tǒng)的可靠性，3)內(nèi)阻和剩余容量關(guān)系。文中結(jié)合電池管理系統(tǒng)在直流操作系統(tǒng)的應(yīng)用進(jìn)行了相關(guān)論述，本系統(tǒng)提高了直流電源運(yùn)行的可靠性。 敘詞：蓄電池 失效模式 內(nèi)阻 Abstract：The paper studies the crux that the battery on-line monitor management system solve according to the analysis of the running battery, the relation between the model of abeyance and internal resistance. Including: 1) The reasonable structure of monitor .2) The reliability of the internal resistance data of single battery in the battery monitor system.3) The relation between internal resistance and the rest of capacity. The paper discusses the use of the battery management system in D.C operating system. The system improves the reliability of the running direct power supply.
