A Device for Measuring the Impedance of Electrochemical Power Sources over a Wide Frequency Range

Currently, active research is being conducted on the influence of the batteries internal state and battery packs internal state on their impedance parameters across various frequency ranges. The result of such studies was the development of methods for the electrochemical power sources state rapid analysis using impedance spectrographs. This paper proposes the implementation of such a device based on multiple microcontrollers and demonstrates its application results. The research purpose was to reduce the size, lower the cost, and create a final product with possibility of conducting research in mobile conditions.
