Python Battery Mathematical Modelling (PyBaMM)

Published June 8, 2021 | Version 22.10

Software Open

Features

Third-party parameter sets can be added by registering entry points to pybamm_parameter_set (#2396)
Added three-dimensional interpolation (#2380)

Bug fixes

pybamm.have_julia() now checks that julia is properly configured (#2402)
For simulations with events that cause the simulation to stop early, the sensitivities could be evaluated incorrectly to zero (#2337)

Optimizations

Reformatted how simulations with experiments are built (#2395)
Added small perturbation to initial conditions for casadi solver. This seems to help the solver converge better in some cases (#2356)
Added ExplicitTimeIntegral functionality to move variables which do not appear anywhere on the rhs to a new location, and to integrate those variables explicitly when get is called by the solution object. (#2348)
Added more rules for simplifying expressions (#2211)
Sped up calculations of Electrode SOH variables for summary variables (#2210)

Breaking change

Removed pybamm.SymbolReplacer as it is no longer needed to set up simulations with experiments, which is the only place where it was being used (#2395)
Removed get_infinite_nested_dict, BaseModel.check_default_variables_dictionaries, and Discretisation.create_jacobian methods, which were not used by any other functionality in the repository (#2384)
Dropped support for Python 3.7 after the release of Numpy v1.22.0 (#2379)
Removed parameter cli tools (add/edit/remove parameters). Parameter sets can now more easily be added via python scripts. (#2342)
Parameter sets should now be provided as single python files containing all parameters and functions. Parameters provided as "data" (e.g. OCP vs SOC) can still be csv files, but must be either in the same folder as the parameter file or in a subfolder called "data/". See for example Ai2020 (#2342)
