Small-Perturbation Electrochemical Impedance Spectroscopy System with High Accuracy for High-Capacity Batteries in Electric Vehicles
A KAIST research team led by Prof. Kyeongha Kwon and Sang-Gug Lee has developed an electrochemical impedance spectroscopy (EIS) system for precise diagnosis of high-capacity batteries using minimal current. This innovation enhances safety and performance metrics in electric vehicle (EV) battery systems. The EIS methodology quantifies battery impedance responses to small electrical signals across frequency ranges, providing critical data on internal battery parameters including state of charge, state of health, and degradation indicators. The technique facilitates detection of variations in temperature-dependent properties, electrochemical reactions, and structural integrity—parameters essential for accurate ...read more
