Change Log

Version 2.4.0 (November, 2024)

  • The project has been updated to MATLAB R2024b with some clean ups.
  • Added brief entry-point descriptions about MATLAB project and Git to Using MATLAB Project. The page also provides links to product documentation for more information.
  • Vehicle1D copmonent has been updated to check that all Live Scripts in SimulaitonCases folder are exported to Markdown files.

Version 2.3.2 (August, 2024)

  • Make sure buildtool-based tests all pass.
  • Update live script to markdown.
  • Add the project navigator app. Clean up project shortcuts.

Version 2.3.1 (June, 2024)

  • Use easy-to-find locations to store markdowns generated from live scripts.
  • Add a project shortcut to Vehicle1D performance design app.

Version 2.3.0 (June, 2024)

App

  • Vehicle1D performance design app is added.

Files and folders organization

  • Simplified filenames: Use shorter file names for the models and scripts. For example, "Case" is used instead of "simulationCase" in filenames for some Live Scripts.

GitHub repository UX

  • Sinced 2.2.0, Live Scripts were converted to Jupiter Notebooks so that they could be viewed directly in GitHub web site in the browser. Now Markdown files are used instead of Jupyter Notebooks. Markdown files are stored under the "Markdowns" folder for the corresponding Live Scripts. This also cleanups the folders with Live Scripts and improves the navigation in the folder tree.

GitHub Actions

  • Use matlab-actions/setup-matlab@v2 in GitHub Actions workflow.

Version 2.2.2 (December, 2023)

  • buildfile.m for MATLAB Build Tool to run tests has been updated.
  • Build Tool is now used to run tests in Battery High Voltage component.

Version 2.2.1 (October, 2023)

  • Detailed PMSM application now uses a new parameterization for FEM parameterized PMSM block.

Version 2.2.0 (September, 2023)

  • The project has been updated to use MATLAB R2023b.
  • MATLAB Build Tool is used to automatically generate HTML files and Jupyter notebooks from all Live Scripts in the project. Jyputer notebooks corresponding to Live Scripts are rendered in the repository web site in the browser.
  • GitHub Actions generates test report and coverage report.

Version 2.1.2 (June, 2023)

  • Added hyperlinks in HTML files to open scripts or models in MATLAB.
  • Models that were saved in previous release have been saved in R2023a.
  • Electric ground block in the top layer of BEV system model has been moved into battery component so that the top layer of a system model represents system architecture only.

Version 2.1 (March, 2023)

  • The project has been updated to MATLAB R2023a.
  • A shortcut button to open MATLAB Test Manager is added in the Project Shortcuts tab of the toolstrip. MATLAB Test Manager requires the MATLAB Test license.
  • Callback Button blocks for configuring simulation cases were removed from all models.

Version 2.0.1 (March, 2023)

  • Updated screenshots of some models.
  • Fixed a broken link to the license file in README.

Version 2.0 (February, 2023)

Architecture

  • BEV system model uses updated components and has simpler and easier configurability for selecting vehicle speed reference input.
  • Components have been updated with cleaner architectures.
  • Component inteface is defined by two types of Connection Bus objects. One is for high voltage electrical connection, the other is for rotational connection. Connection bus definitons help separate architecture and implementation, making component connection robust and scalable in large system modeling. Definition files can be found in the Interface folder.

Testing

  • Components have individual harness models and tests.
  • Tests for each component can be run by a test runner script which runs all tests in one go in each component and reports pass/fail summary.
  • Test runner also measures MATLAB code coverage and generates a report. This allows us to perform test driven development.

Components

  • High voltage battery component provides four different models: Basic, System simple, System, and System tabulated. They are all system level models and abstract, but they prodive different fidelity levels of the model. See README in Components > BatteryHighVoltage for more details.
  • Motor drive unit component provides four different models: Basic, Basic thermal, System, and System tabulated. They are all system level models and abstract, but they prodive different fidelity levels of the model. See README in Components > MotorDriveUnit for more details.

Input signal design

  • A custom Simulink library providing Signal Source Blocks has been added. It streamlines the design, use, and modification of input signal patterns, both continuous and discrete ones. Blocks are built with a custom Signal Designer class. These are included in the Utility > SignalDesigner folder.

Detailed model applications

  • A detailed battery model built with a custom Simscape library has been removed.
  • This project will focus on the vehicle system-level applications in future updates.
  • A recently released new project Electric Vehicle Design with Simscape serves as an alternative to explore detailed model applications. It provides BEV design workflows using detailed models for detailed analysis.

Version 1.2.2 (December, 2022)

  • Fixed a broken link in the main script.
  • Minor change in the value of road-load parameter A for the main BEV model.

Version 1.2 (May, 2022)

Highlight

  • GitHub Actions continuous integration has been enabled to automatically run tests when the repository at github.com recieves a push.
  • Unit tests and harness models for the tests have been added to the BEV system model (BEV), high-voltage battery (BatteryHighVoltage) component, longitudinal vehicle (Vehicle1D) component, and detailed high-voltage battery (BatteryHighVoltageDetailed) component. More tests will be added in the coming updates.

MATLAB Release

  • This version requires MATLAB R2022a or newer.

Project

  • Files and folders were reorganized. BEV and Components folders contain abstract models only. Detailed models have been moved under DetailedModelApplications folder.

Models

  • DAESSC solver is used.
  • Simulink model files are saved in mdl format. Starting from R2021b, MDL format is based the new text format which is feature parity with binary SLX format.
  • Abstract high-voltage battery component has three different fidelity levels; isothermal (same as before), simple thermal (newly added using System-Level Battery block from Simscape Driveline), and thermal (newly added using Battery block from Simscape Electrical). They all run fast.
  • Longitudinal Vehicle block from Simscape Driveline is added as a new (and default) referenced subsystem. The previous custom block is still included too.

Version 1.1 (October, 2021)

  • A detailed high-voltage battery pack component is added.
  • The BEV model supports three different component configurations using Subsystem Reference:
    1. All basic comopnents (same as version 1.0).
    2. [New] With a detailed high-voltage battery as grouped-single module.
    3. [New] With a detailed high-voltage battery as multi-module.
  • A live script evaluating the BEV model with high-voltage battery component at different fidelity levels is added.
  • This project requires MATLAB R2020b or newer.

Version 1.0 (November, 2020)
