蓄电池在线检测方法研究

Research of On-line Testing Method for Accumulator Battery

在对阀控铅酸蓄电池的性能指标、失效机理、检测方法研究的基础上，通过比较各种检测方法，提出了一种新的蓄电池内阻在线检测方法——四线两端法，阐述了四线两端法的测试原理，给出了该方法在蓄电池在线检测中的检测步骤，同时分析了影响测量精度的主要因素，提出了提高测量精度所采取的措施，并给出系统测量误差。

Based on researches on performance guideline, disabled mechanism and testing method of VRLA this paper puts forward an alternating current four-terminal method, a new on-line testing method of VRLA. The authors expound testing theory and introduce testing step for on-line testing of VRLA. At the same time, they also analyse the main factors which affect testing precision, and puts forward measures which improve testing precision and compute testing error of testing system.
