Handheld Battery AC and Time Domain characterization tool on Attiny series 2
This repository is about a "pen size" (handheld) tool for quick measurement of various types of battery resistances/impedances.
This tool uses 2 different methods for measuring impedance values:
- "standard" AC 1 kHz impedance, as used by many. - Direct Current Impedance Spectroscopy, extracting the bulk (solution) resistance and the SEI (Solid Electrolyte Interphase) resistance, allowing better insight in both battery ageing and battery safety. Normally this would require a lengthy procedure via EIS (Electrochemical Impedance Spectroscopy) and model fitting. This tool allows to do it fast…
