A parameter estimation method for a simplified electrochemical model for Li-ion batteries. Li, J., Wang, L., Lyu, C., Liu, E., Xing, Y., & Pecht, M. 2018. ISSN: 00134686 Pages: 50–58 Publication Title: Electrochimica Acta Volume: 275doi abstract bibtex Traditional electrochemical algorithms are too complex for use in real-time battery management systems (BMSs). Determination of parameters and implementation of algorithms are the key challenges for electrochemical models for Li-ion batteries. This paper develops a simplified electrochemical model that incorporates open-circuit voltage, liquid-phase diffusion, reaction polarization, and ohmic polarization, and uses a fast operating test to identify all the parameters to solve these challenges. The model is then implemented and compared against experimental measurements. Validations of parameter estimation and charge/discharge behaviors indicate that the developed parameter estimation method for the electrochemical model is effective. With this model and parameter estimation technique, electrochemical model-based state of charge (SOC) estimation can be realized online and can provide accurate results.
