准确测量锂离子电池内阻的方法研究

Studies on Accuracy Measurement About Lithium Ion battery Impedance

在研究锂离子电池内阻的构成,分析物理模型及目前部分测量方法的基础上,提出了即时同步测量方法,消除了锂离子电池内阻测量过程中的电容效应,测量准确、简单、可靠,有较好的实际使用效果。

Based on the research of the constitution of lithium ion battery impedance and the analysis of physical model and part of the present measuring techniques,the author poses an immediate synchronization measuring technique which could eliminate the capacity effect in the process of measuring lithium ion battery impedance. This technique is accurate,simple,reliable,and the actual performing result proves to be good.
