JuliaSimBatteries.jl for advanced lithium-ion battery simulation.

Lithium-ion battery models are highly non-linear systems of stiff, partial differential-algebraic equations (PDAEs). One of the key challenges of working with these models is to solve the system of equations over a range of inputs and parameters. Many commercial and open-source battery modeling tools are prone to sporadic failure stemming from issues in setting up, initializing, and solving these systems.

Calibrating HVAC and battery models with JuliaSim's Model Optimizer.

Building large scale models for industrial systems requires incorporating the real-world behavior of the system inside the mathematical model. In order to achieve this, models need to be calibrated based on collected experimental data. Calibrating models to data, however, is difficult  due to the behavioral complexity of the models and the challenges that are brought in by the data, such as noise, partial observability or sparsity of the measurements.

New Ways to Compile Julia

Discover new ways to compile Julia

At JuliaCon Local in Eindhoven in December 2023, Jeff Bezanson, co-creator of Julia and co-founder of JuliaHub, presented a talk on the state of Julia binaries and the goal to generate smaller ones. A common request by developers in the Julia developer survey is the ability to produce smaller, self-contained binaries. In the Eindhoven talk, Jeff shared a graph showing the progression of binary sizes generated by PackageCompiler.jl. There has been significant progress since then, and the latest update shows a huge drop in size, thanks to the trimming mechanism.
