精確測量蓄電池內阻方法的研究

摘要：蓄電池作為電源系統停電時的備用電源，已廣泛的應用于工業生產、交通、通信等行業。蓄電池狀態的重要標志之一就是它的內阻。因此實現蓄電池內阻的在線實時監測,將有重要的實際意義。本文提出了基于鑒相處理技術的方法，介紹了該測量方法的原理，同時提供了檢測蓄電池的交流恒流源的設計思想。 敘詞：交流恒流源，蓄電池，內阻 Abstract：The battery is standby power supply when the power source system cut , and it widely applies to the profession of industrial production, traffic, communication and so on. Battery impedance is one of its important sign. So it has the important practical significance to realize the battery impedance on-line and real-time measurement. This article has presented a method to measure battery impedance based on phase detector processing technology and the theory of this measurement method. Simultaneously it has presented a thought of designing AC constant current source to apply to measure battery impedance. Keyword：AC constant current source battery impedance
