Battery Systems: introduction

Information

This curriculum module contains interactive MATLAB® live scripts that contain learning material covering the fundamental concepts and terminology of battery systems. The focus is on designing and modeling battery systems using different tools (MATLAB, Simulink, and Simscape).

Background

You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. This module covers basic battery pack design, battery cell modeling (electrical and thermal), and the basics of battery management systems. It also includes examples of modeling using different approaches (MATLAB, Simulink, and Simscape) and State of Charge (SoC) estimation.

The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.

Prerequisites

This module assumes knowledge of electrical circuits as discussed in DC Circuit Analysis. There is minimal MATLAB knowledge required for these scripts, but you could use MATLAB Onramp as a resource to acquire familiarity with live scripts and MATLAB syntax. Depending on your learning path through the module, you might want to add Simulink Onramp or Simscape Onramp to gain familiarity with these tools.

Getting Started

Accessing the Module

On MATLAB Online:

Use the link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.

On Desktop:

Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts, and double-click BatterySystem.prj. It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start.
