摘　　要：蓄电池作为电源系统停电时的备用电源,已广泛应用于工业生产,以及交通、通信等行业。蓄电池状态的重要标志之一就是它的内阻。因此实现蓄电池内阻的在线实时监测,将有重要的实际意义。本文提出了基于鉴相处理技术的方法,介绍了该测量方法的原理,同时提供了检测蓄电池的交流恒流源的设计思想。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 articlehas 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.
