蓄電池內阻監測的意義

摘要：近年來，隨著電力工業的發展和信息產業的發展，閥控式鉛酸蓄電池（VRLA，俗稱免維護鉛酸蓄電池）的使用得到空前的普及。由于有關VRLA電池的使用知識普及不夠，VRLA電池在使用過程中暴露出許多問題，這些問題嚴重影響VRLA電池的使用壽命，并進而影響到相關設備的運行安全。本文闡述有關VRLA電池使用的基本常識，分析對鉛酸蓄電池組內阻實時監測的重要性。希望本文對VRLA電池的使用和維護有所助益。 敘詞：閥控式鉛酸蓄電池（VRLA） 內阻 容量 交流阻抗法 監測 Abstract：In recent years, the VRLA (usually called maintenance-free lead-acid storage battery) has been widely used with the development of electric industry and information industry. The lack of knowledge about VRLA battery results in many problems, which seriously affects the duration of VRLA and hence having a bad effect on the security of relevant equipment. The article explains basic knowledge about how to use VRLA, and tells the importance of real time monitoring of internal resistance to VRLA battery. The author hopes that it can be of help for the use and maintenance of VRLA battery. Keyword：VRLA, Internal Resistance, Capacitance, AC Impedance Method, Monitoring
