Seminar: Battery Modeling with COMSOL Multiphysics®
Battery design and development has been an integral part of the electric vehicle and energy industries, particularly as the investment in eco-friendly technologies has increased. The COMSOL Multiphysics® software is a multiphysics simulation platform that helps you set up physics-based, high-fidelity models of batteries of different types and with arbitrary chemistry. Such models can include material transport, charge transport, heat transfer, fluid flow, and electrochemical reactions. The software also features ready-made modeling interfaces for the most common battery types, such as the lithium-ion battery, NiMH, and lead-acid batteries. You can also model at different scale from the microscopic scale using heterogeneous models, to the cell scale using porous electrode theory, to the pack scale with hundreds of battery cells. It is also possible to incorporate lumped models into system models and digital twins, such as electric vehicle drivetrains, and create simulation apps for use by nonexperts.
Join us for this seminar to learn from keynote talks and technical presentations about the benefits of using multiphysics simulation to study and design battery systems for automotive, portable, and stationary applications. We will also give an overview of the relevant features in COMSOL Multiphysics® and demonstrate how the software can be used across large development teams.

Tech Socials are informal sessions that allow you to interact with COMSOL staff and other attendees. They can cover any modeling-related topic that you like and give you the opportunity to ask COMSOL technology product managers and applications engineers your questions. Join us!
Batteries are widely used to power equipment in the aerospace and defense industries. The most commonly used technology is lithium-ion, which boasts a high energy density, long cycle life, and low rate of self-discharge. However, lithium-ion batteries are sensitive to temperature conditions, which can impact their performance. To ensure optimal performance and efficient thermal management, the use of modeling and simulation in the design process is crucial. Modeling and simulation are powerful tools that can help us understand and predict the behavior of battery systems while also reducing development time and costs.
COMSOL Multiphysics® and the Battery Design Module offer a range of capabilities for building detailed models of battery cells and packs, capturing phenomena such as electrochemistry, species transport, heat transfer, fluid flow, and structural mechanics. When combined with the Heat Transfer Module, users can access a unique environment for running thermal analyses of battery systems, accounting for heating due to activation losses, Joule heating, conjugate heat transfer, nonisothermal flow, and other coupled phenomena.
In this session, we will provide an overview of the functionality that COMSOL Multiphysics® offers for battery design and thermal analysis. We will demonstrate these capabilities using models at both the battery cell and battery pack levels.
Vikas Bansal, Enphase Energy
In this keynote talk, Vikas Bansal, senior manager of mechanical engineering at Enphase Energy, will present a simulation-driven approach to studying thermal runaway in lithium-ion battery energy storage systems (BESS) using the COMSOL Multiphysics® software. As BESS plays a crucial role in renewable energy integration, ensuring safety and UL9540A compliance is essential.
Bansal will demonstrate simplified and detailed 3D models that simulate venting, heat release, pressure rise, and propagation between cells in a 20-cell battery pack. He will also cover parametric studies on factors such as busbar thickness, heat release rate, and venting direction on thermal propagation, showing strong correlation with UL9540A laboratory test data.
He will conclude by emphasizing how COMSOL Multiphysics® helps optimize battery pack design, reduce physical testing, and improve safety in energy storage systems.
Participate in a discussion forum with colleagues and COMSOL engineers to discuss battery modeling. Engineers will be made available to answer questions about your applications and suggest the best techniques for modeling them.
Battery systems are often burdened by unwanted side reactions at the electrodes. The COMSOL Multiphysics® software and its Battery Design Module add-on product can be used to simulate various aging and degradation mechanisms, resulting in capacity fade in batteries. The flexibility of the Battery Design Module also enables you to include any arbitrary by-reaction, such as hydrogen and oxygen evolution, solid electrolyte interface growth due to deposition, metal plating, metal corrosion, and graphite oxidation in your battery models.
In this session, we will present the capabilities of the Battery Design Module for modeling degradation in batteries and demonstrate the process of building and running a capacity fade model.
