Python Battery Mathematical Modelling (PyBaMM)

Features

• Revision of the hysteresis notebook to include the method implemented in the module axen_ocp. (#4880)
• Added axen_ocp module within submodel interface.open_circuit_potential to handle an OCP with hysteresis. (#4816)
• Creates a 'calc_esoh' property in battery models (#4825)
• Added 'get_summary_variables' to return dictionary of computed summary variables (#4824)
• Added support for particle size distributions combined with particle mechanics. (#4807)
• Added InputParameter support in PyBamm experiments (#4826)
• Added support for the "pchip" interpolator using the CasADI backend. (#4871)

Breaking changes

• Added skip_ok option to step to allow for steps to be skipped if they are infeasible at initial conditions. (#4839)
• Deprecated CrateTermination and renamed it to CRateTermination. (#4834)

Bug fixes

• Fixed a bug with observing the outputs of 2D FEM simulations. (#4912)
• Fixed a bug in simulating FEM models with the IDAKLUSolver. (#4879)
• Moved concentration inside x-averaged when calculating LLI due to LAM variables (#4858)
• Fixed a bug that caused the variable "Loss of lithium due to {domain} lithium plating"to have the domain "current collector" (should not have any domain at all) if the "x-average side reactions" option was set to "true". (#4844)
• Fixed interpolation bug in pybamm.QuickPlot with spatial variables. (#4841)

Optimizations

• Performance improvements to IDAKLUSolver initialization and processed variables. (#4878)
• Improved search to handle cases with shorter input strings and provide more relevant results. (#4735)
