Model, Simulate and Analyze Faults for Battery System
Overview
Batteries play a critical role in the electrification of systems—from large-scale power grids and renewable energy storage to electric vehicles and consumer electronics.
Accurately modeling the electrical and thermal behavior of individual cells, as well as their interactions at the module and pack levels, is essential for safe and efficient system performance. In addition to electrical dynamics, thermal management is crucial for meeting overall product requirements.
Beyond simulating various operating scenarios, fault simulation in battery systems is equally important. It enhances safety and reduces development time by preventing costly rework. Testing BMS robustness against sensor communication issues (such as noise, drift, and delays) and internal faults (such as open circuits, short circuits, and cell abnormalities) is vital for ensuring system reliability.
Simscape Battery, along with Simulink Fault Analyzer, supports the simulation of complex fault scenarios—including thermal runaway, disconnections, and wiring defects.
