Hi,
I am trying to calibrate the full-cell OCV of the DFN physics-based model of the NMC532 cell. Even with multiple optimizations, the middle part of the curve doesn't calibrate with the experimental data. Can anyone suggest possible causes or solutions?
Attached is the comparison of exp. and simulated OCV curves obtained after optimization.
Hello,
1. Temperature dependency: Most quantities are temperature-dependent, meaning they exhibit a behavior that varies with temperature. If you are comparing experimental data obtained at different temperatures, it is crucial to consider the temperature dependence of the model parameters. Make sure to incorporate appropriate temperature corrections or factors in your physics-based model to align the OCV curve with experimental data at various temperatures.
2. Experimental measurement uncertainties: Experimental measurements may contain inherent uncertainties or systematic errors that can impact the accuracy of the comparison. It is important to carefully evaluate the quality and reliability of the experimental data and consider statistical analysis to assess the uncertainties associated with the measurements.
