Electrification Library 1.9 is part of Modelon’s 2023.1 release. New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.
New Features and improvements
- New tutorial: Thermal dynamics (part of the Getting Started tutorials)
Battery thermal management
Several additions to support thermal management use cases with batteries:
- New examples that demonstrate different aspects of thermal management (Batteries.Experiments.Thermal).
- All thermal cell models now have a common interface, enabling re-usable experiments that are compatible with all of them.
- New cell experiments that include a thermal model (examples and templates in Batteries.Core.Experiments).
- Introduced a Lumped thermal cell model that supports thermal resistance to the surface.
- Thermal connections to the cells are now made via surface nodes instead of the core node (in CommonCell, IndividualCells, Prismatic and Cylindrical models), with a parameter for reverting to the old behaviour (
- Both the IndividualCells and CommonCell thermal models now support using a separate cell model, allowing cell models to be separately parametrized and validated.
- Improved support for separate parametrization of cell and pack mass in the Lumped thermal model.
- Unit test examples with a single thermal cell and a pack/module (Batteries.Thermal.Cells.Experiments and Batteries.Thermal.Experiments).
- Added summary outputs: cell heat losses, minimum cell temperature and C-rate.
- New ActiveCooling example, demonstrating the Thermostat battery temperature controller, with external cool_request signal. This is a generalization of the old FanThermostat controller.
- New example cell with tabular parameters and temperature dependencies (Batteries.Core.Examples.NCA).
- It is now possible to change the temperature unit in the tabular voltage and impedance models.
- Updates to thermal adapters for discretized cells.
- More flexible and consistent parameters for the Lumped thermal pack model.
- Added summary outputs for accumulated charge and energy (e_out and Q_out).
- Improved support for specifying tabular parameters relative to Ah instead of SoC (for example in Core.OCV.Table).
- New basic example with battery cell imbalances (Batteries.Experiments.Imbalances.RandomCellParameters).
- Template for importing a causal model of a battery (e.g. using FMI).
- Batteries.Control.ContactorControl now allows starting with contactors closed without going through pre-charge.
- New example experiment (MotorGeneratorQuadrants) demonstrating motoring and generating in all four quadrant.
- A re-usable experiment for evaluating machine limits (LimitSweep).
- Added options for specifying tabular torque limits relative to only speed (Table1Dw) and relative to speed and temperature (Table2DwT).
- Added power angle summary output (phi_power) to electromagnetic AC machine models.
New examples that demonstrate SiL use cases, where controllers and plant models are imported and exported using FMI.
- New example (ControllerImport): Import an external controller.
- New example (PlantExport): Export a plant model with an interface for a separate controller.
- Introduced protection against direct connections of the thermalPort of multiple components (more information in the Thermal chapter of the User's Guide).
- An improved DCSeries component, for connecting e.g. battery packs in series.
- Added the DCCurrent constant source.(
- Improved robustness to missing ambient thermal connections.
- Fixed parameter issues in the IndividualCells model.
- Fixed an issue with the Nominal battery models that could lead to a division by zero error when heat losses were not enabled.
- Fixed an invalid default parameter for maximum power in the Nominal battery model.
- Various improvements to documentation.
- Several minor fixes.
- Removed several deprecated components.
