摘　　要：内阻与短路电流是反映阀控式铅酸蓄电池性能的重要指标。国家标准中的直流二次放电法需要用大电流放电,难以实现大容量蓄电池的内阻测量。提出了一种小电流二次放电法测量蓄电池内阻与短路电流的新方法,通过大量实验验证了此方法与标准方法的大电流放电测量得到的结果一致,并给出了放电电流的经验值,解决了大容量铅酸蓄电池内阻和短路电流测量的难题。Internal resistance and short-circuit current are important parameters to reflect the performance of VRLA batteries.Large current discharge will be needed in conventional measurement methods such as DC secondary discharge in the national standard,so it is difficult to achieve the measurement for large capacity batteries.In this paper,a new method was put forward for measuring the internal resistance and short circuit current by using a small current in the secondary discharge.It is verified by a large number of tests,and gives the empirical value of discharge current.
