摘要

在线快速阻抗谱(iRIS)是一种快速测量阻抗的方法，可以在广泛的同时频率范围内进行测量。蒙大拿理工大学(MTech)已由Dynexus Technology赞助，以增强iRIS系统的功能，包括提高整体测量分辨率。基线iRIS系统的规定分辨率为$\pm 0.01\mathrm{m}\Omega$，而先前开发的分辨率增强套件表明，分辨率可以提高到$\pm 0.01\mathrm{m}\Omega$。对增强套件的持续研究表明，iRIS系统可能达到比$\pm 5\ \mu \Omega$更好的分辨率。概述了这种新方法，并给出了显示非常高分辨率的测量结果。

High Resolution System for Rapid Broadband Battery Impedance Measurements

Inline Rapid Impedance Spectroscopy (iRIS) is a method of quickly measuring impedance measurements over a broad range of simultaneous frequencies. Montana Technological University (MTech) has been sponsored by Dynexus Technology to enhance the iRIS system capabilities, including an improvement in the overall measurement resolution. The baseline iRIS system has a stated resolution of $\pm 0.01\mathrm{m}\Omega$ and a previously-developed resolution enhancement kit demonstrated an improvement down to $\pm 0.01\mathrm{m}\Omega$. Continued research with the enhancement kit has shown that the iRIS system can potentially achieve resolutions better than $\pm 5\ \mu \Omega$. An overview of this new approach along with measurement results that demonstrate very high resolution is presented.
