EL Version 1.12

Electrification Library 1.12 is part of Modelon's 2024.2 release. New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

Improvements

Updated example: Electric vehicle range

  • Added friction brakes (and brake blending control) to the ElectricRange example.
  • Changed to the polynomial (CuFe) loss model for the electric machine.
  • The 1D chassis model has been parametrized to match a corrsponding MutliBody3D model in the Vehicle Dynamics Library, and wheel slip has been included for improved correlation with vehicle models that have a tire model.

Batteries

  • Added nominal cell current (iCell_nom_1C) to core models.
  • Added support for ns and np > 1 in core battery experiments.
  • Support for discretization in example that compares thermal cell models (Batteries.Thermal.Cells.Experiments.CylindricalCompared
  • Introduced adapters for accessing single side surfaces of prismatic cells (SelectSurface and SelectSurfaceMultiple).
  • Introduced adapter for cold plate with discretization in 2 dimensions (ColdPlate2D).
  • Made the Nominal battery pack more robust to solve in steady state.
  • Fix: Default cell limits no longer vary with the number of cells (in a lumped battery).
  • Fix: Invalid assert message for discretized thermal cell models.

Machines

  • Added ElectricCar example machine, with smooth loss model (polynomial).
  • Added Steady experiment, for evaluating e.g. losses/efficiency at a specific steady state operating point.
  • Fix: Some core machine models had a sign error in the output summary.p_loss.
  • Improved robustness of the SPMSM design model when constraining the stator diameter.

Component design / sizing

  • An example of a multi-point design experiment for an electric machine: Electrification.Machines.Experiments.Design.Multipoint.
  • Made it possible to override and couple design variables (to enable multi-point experiments).
  • Automatic integration with JPL (Jet Propulsion Library) if a settings_JPL component is present. This allows controlling the design models based on settings_JPL.onDesign.

Other

  • Minor paramerer dialog fixes.
