Electrochemical impedance spectroscopy (EIS) is a powerful tool for monitoring rechargeable batteries through state of charge and state of health estimation.

Abstract

Electrochemical impedance spectroscopy (EIS) is a powerful tool for monitoring rechargeable batteries through state of charge and state of health estimation. In practical applications, EIS may be performed using ad-hoc electronics embedded in the final product. The accuracy of these custom impedance measurement systems must be validated against laboratory instrumentation. This paper presents the software tool EasyEIS, which we developed to perform EIS using a standard commercial source measure unit on a lithium-ion battery to validate results from a custom impedance measurement system. EasyEIS also includes a software-based sinusoidal waveform generator function that allows cost-effective EIS also in instruments that do not offer any hardware sinusoidal function generation feature.
