Battery Pack Modelling for Electro-thermal Analysis

Overview

In the age of "electrification of everything," batteries play a pivotal role in powering Electric Vehicles and energy storage systems for renewable energy sources. To ensure reliable and efficient battery operation, engineers face the challenge of understanding and managing various factors, including the electrical behavior and temperature regulation of the batteries. This necessitates the development of complex models that span multiple physical domains.

In this webinar, we will demonstrate how engineers can model battery cells using predefined components or customize them according to specific requirements. Participants will learn the process of modeling a cell and, in the case of a custom cell, refining its electrical and thermal design as needed. This approach will lead to the development of a comprehensive cell model, which can then be scaled up to build modules and complete battery packs using Simscape Battery

In addition, the talk explores the creation of reduced-order models for battery packs, focusing on spatial thermal variations during charge and discharge cycles. This approach enables engineers to analyze and address thermal issues within the battery pack, further enhancing its performance and longevity.

Highlights

• Battery cell modeling and scaling it to a Module and Pack
• Reduced Order Models (ROM) to capture spatial thermal variations
• Evaluating Electro-thermal behavior and designing Battery Management System
