Abstract :
Impedance model contains a lot of information that can indicate performance of battery. Therefore, establishment of accurate impedance model is very important. In this paper, impedance model of Li-ion battery is examined by electrochemical mechanisms analysis and experimental measurement. The basis for the form of the model has been linked to internal processes of the battery and validated using experimental data. The impedance behavior during individual discharge cycles as well as over its cycle life is obtained. The proposed model will greatly help research on circuit simulation, multi-cell battery analysis, battery test and monitoring, prognostics and battery health management.
