COBRAPRO: A MATLAB toolbox for Physics-based Battery Modeling and Co-simulation Parameter Optimization

COBRAPRO is a new open-source physics-based battery modeling software with the capability to conduct closed-loop parameter optimization using experimental data. Physics-based battery models require systematic parameter calibration to accurately predict battery behavior across different usage scenarios. While parameter calibration is essential to predict the dynamic behavior of batteries, many existing open-source DFN tools lack parameter identification features. COBRAPRO addresses this gap by featuring an embedded parameter optimization routines that optimizes the model parameters by minimizing the error between the simulated and experimentally observed current-voltage data. With COBRAPRO, users can non-invasively identify unknown battery model parameters for any given battery chemistry.
