Modeling and Simulation of Faults in a Battery System

Overview

MathWorks engineers will demonstrate how to model and simulate faults in battery systems. We will showcase:

1. How to inject faults in a battery model including additional resistance fault, internal short fault, and exothermic reactions.
2. How to characterize the thermal runaway behavior of a battery cell by simulating an accelerating rate calorimetry (ARC) test.
3. How the battery management system (BMS) responds under fault conditions.
4. How to conduct a Failure Mode and Effects Analysis (FMEA) per industry safety standards while leveraging simulation results

Highlights

Attendees will learn how to:

• Inject and simulate faults in a battery model using Simscape Battery
• Characterize the thermal runaway behavior of a battery cell using Simscape Battery
• Detect fault conditions using Stateflow
• Conduct a Failure Mode and Effects Analysis (FMEA) of a battery management system (BMS) while leveraging simulation results using Simulink Fault Analyzer
