Battery models many times contain unknown parameters, for instance diffusion constants or rate constants, that are hard to measure in separate experiments outside (ex-situ) a battery cell. To fit model parameter values to experimental data, the
Parameter Estimation (
) node, which may be added to a
Study (
) node in the model builder tree, can be used.
The documentation of the parameter estimation node and the optimization solvers is found in the Optimization Module User’s Guide, which is supplied with the Battery Design Module irrespective of whether a separate Optimization Module license is purchased.
