Open source online electrochemical impedance spectroscopy data analytics tool

Journal of Power Sources, vol. 615, pp. 235049

Abstract

This paper presents an open-source platform for automating the analysis of electrochemical impedance spectroscopy measurements to improve energy systems’ diagnostic and prognostic capabilities. The platform addresses the main challenges associated with impedance-based estimation techniques in electrochemical energy storage systems, mainly by simplifying the aggregation of impedance data from different sources and enabling the comprehensive application of advanced analytical methods. Initial results, particularly in the area of battery temperature estimation using support vector regression, underline the potential of the tool to improve diagnostic performance. The platform encourages collaborative development, facilitates ongoing improvements, and ensures seamless integration with battery management systems to increase safety and operational efficiency by making it available as open-source software.
