Description

This lab experimental data repository contains open-circuit voltage (OCV) and dynamic test data of the commercial A123 26650 m1b ( 2.5 Ah LiFePO4) cylindrical cell. This dataset was collected at the High-Voltage Battery Research Lab at University of Colorado Colorado Springs using an Arbin BT2000 battery cycler and a Cincinnati Sub-zero thermal chamber. This dataset has been used for the model parameterization of a coupled electro-thermal equivalent-circuit model (CET model) in the following publications: A. K. de Souza, G. Plett and M. S. Trimboli, "Lithium-Ion Battery Charging Control Using a Coupled Electro-Thermal Model and Model Predictive Control," 2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020, pp. 3534-3539, doi: 10.1109/APEC39645.2020.9124431.
