摘要
分析了几种常用电池内阻测量方法,提出了一种在线快速检测蓄电池内阻的直流充电法。实验数据表明,用直流充电法分析蓄电池内阻同样可以获得与其他测量方法相同的结论。通过图表清晰地描述了蓄电池内阻在充电过程中的变化情况,探讨了直流充电法在蓄电池充电和运行管理中应用的可行性和实用价值。
This paper analyzes several common methods of measuring battery internal resistance and puts forward a method of chcking battery internal resistance quickly on line named DC-current charging method. The data of experiment showed that using this method could obtain the same results as other methods of meas- urement. This paper describes clearly the changes of battery internal resistance during charging period with diagrams, and probes into feasibility and practical use of DC-current charging method in charging and utilization of battery.
