基于双相关算法的蓄电池交流阻抗测试研究

Research of measuring method based on double-association algorithm for battery AC impedance

针对常见蓄电池交流阻抗测试方法精度不高的问题,提出了基于双相关算法的测试方法,给出了系统框图,阐述了测试原理。采用Lab VIEW 2011软件进行了两种方法的数学建模和仿真。结果表明,该阻抗测试方法能有效地抑制噪声干扰,可实现对蓄电池交流阻抗的精确测量。

Aiming at the disadvantages of low accuracy of usual testing methods for battery AC impedance, an testing method based on double correlation algorithm was introduced. The system block diagram was given and the testing principle was described. The modeling and simulation were carded out with software LabVIEW for both proposed and usual method. The results show that the proposed method can suppress noise disturbance more effectively and realize the precision measurement of battery AC impedance.
