COMSOL Day: Vehicle Electrification

Join us and fellow engineers and scientists to learn about the advances simulation has reached within electric vehicle development, design, and optimization.

COMSOL Day: Vehicle Electrification will provide COMSOL Multiphysics® users and those new to the COMSOL® software with presentations and demonstrations that focus on modeling and simulation techniques in areas relevant for a wide range of e-mobility applications. You will learn about software features and best practices from applications engineers, and invited speakers and panelists from industry will provide their perspective on the importance of simulation in electrified vehicle development.

The program is split into two parallel rooms, where each focuses on a major e-mobility modeling field. One room covers low-frequency electromagnetics within power trains and the other room covers power storage and application within and through batteries, fuel cells, and supercapacitors. In addition, there will be breakout discussions in our Tech Cafés where you can investigate modeling your specific applications with new and experienced users as well as COMSOL engineers and developers.

Electric Power Train (Main Room)
Sessions in this room will cover topics such as electric components, motors, and NVH.

Power Storage and Application (Parallel Room)
Sessions in this room will cover topics such as the electrochemistry, fluid flow, mass transfer, and thermal management within batteries, fuel cells, and supercapacitors.

Tech Cafés
Discuss topics including simulation apps, systems modeling and optimizing fuel cells, batteries, and supercapacitors for automotive applications with colleagues, COMSOL application engineers, and developers.



Please join us 10 minutes before the presentation starts to settle in and make sure that your audio and visual capabilities are working.


To start, we will briefly discuss the format of the day and go over the logistics for using GoToWebinar.


Simulation provides an important contribution to faster, more cost-effective research and development. In this session, you will learn more about the current modeling trends at leading industrial companies and research institutes when it comes to developing and improving designs for the electrified future of mobility. A special focus will be on the democratization of simulation.

Parallel Session
Low-Frequency Electromagnetics Modeling

The AC/DC Module is designed for low-frequency electromagnetics modeling. As an introduction to COMSOL Multiphysics® and this type of modeling, this session will investigate the phenomena and demonstrate some of the key features and techniques included in the AC/DC Module, such as coil modeling, inductive heating, electric motors, electrical circuits, and the efficient modeling of thin layers.

Introducing the Fuel Cell & Electrolyzer Module

COMSOL introduced the Fuel Cell & Electrolyzer Module in COMSOL Multiphysics® version 5.6 to expand the sphere for modeling electric vehicles and energy conversion. This product can be used for modeling low- and high-temperature hydrogen fuel cells and water electrolyzers based on different operating parameters, such as proton exchange membranes (PEM), hydroxide exchange (alkaline) membranes, molten carbonates, and solid oxides. In this session, we will present and demonstrate simulations of electrochemical reactions, electrolyte charge transport, gas-phase mass transport, and convective flow, as well as two-phase water/gas transport.

Tech Café: Simulation Apps

Simulation apps enable you to expand your modeling and give more control to your colleagues who require simulations for their designs and processes. You can create user-specific modeling environments that are best suited to their simulation needs while also being easy enough for them to use, even if they are not modeling experts. During this Tech Café, you can discuss how best to develop simulation apps with COMSOL engineers, who will also be answering your specific questions.

Invited Speaker
Optimum Electromagnetic and Thermal Design of DC-Link Capacitors

Martin Kessler, Robert Bosch GmbH

This session presents the need of simulation and the appropriate solution with COMSOL Multiphysics® along the complete development trajectory of a DC-link capacitor for traction inverters. From conceptual work to worst case analysis, coupled electromagnetics and thermal simulations are used for an optimized and secured component. On the one hand, the results point out the limits and potentials of the specific designs. On the other hand, COMSOL Multiphysics® helps to a profound knowledge about the interactions between the numerous design variables.

Break for Lunch
Introduction to COMSOL Multiphysics® for New Users

Learn the fundamental workflow of COMSOL Multiphysics®. This introductory demonstration will show you all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.

Parallel Session
Modeling Electric Motors

In this session, you will learn about using COMSOL Multiphysics® to model synchronous and asynchronous electric machines as motors and generators. We will cover simulating the electromagnetic fields in both 2D and 3D, extracting torque, losses, and all relevant variables necessary to assess behavior and efficiency in various regimes. You will also see how the AC/DC-based physics in electric motors can be coupled to heat transfer to calculate cooling requirements, as well structural mechanics and acoustics behavior to predict noise.

Battery Modeling

Get an overview of using the COMSOL® software for modeling batteries. Learn how to incorporate porous electrodes and electrode reactions including transport of ions and current in your battery models. We will address the simulation of lithium-ion battery power and capacity using realistic vehicle drive cycles, modeling of thermal effects on both cell and pack levels, safety aspects, and modeling capacity fade.

Tech Café: Systems Modeling

The use of lumped models derived from high-fidelity models in systems simulations is key to bringing all of the different factors of electric vehicles in concert for efficient drivetrain operation. This involves being able to continuously validate such simulations, not only with experimental data but also together with the high-fidelity models themselves. This Tech Café will discuss the features and processes available with COMSOL Multiphysics® that augment these synergies and enable better development and design of the components that make up electric vehicles.

Invited Speaker
Addressing Battery Challenges with Mathematical Modeling

Eva Fontes, Intertek

The biggest challenges for battery design are to optimize energy density, power density, charging time, life, cost, safety, and sustainability. Modeling and simulation are very efficient methods that can assist researchers, developers, and designers in meeting these challenges. In the development of a cell design, the optimization of fundamental components of the cell (such as the electrodes, electrolyte, and separator), and the understanding of how their properties affect the performance and safety, can be accelerated using modeling and simulations. In the development of a battery design, the systems for thermal management, current collection, and state-of-health monitoring can also be developed with high-fidelity multiphysics simulations. During this talk, challenges for cell and battery design will be discussed and examples will be given of how they can be addressed with mathematical modeling.

Invited Speaker
Topology Optimization for an Efficient Design of an Electric Motor

Steffen Rothe, Volkswagen Group Components

During this talk, an innovative numerical optimization algorithm is presented and used to create a rotor design with reduced magnet material for an electric motor (IPMSM). With the help of COMSOL Multiphysics®, the different physical fields influencing the electric motor can be modeled simultaneously, which allows the coupled optimization. The performance and reliability of an electric motor is mainly characterized by the interaction of electromagnetic and mechanical properties. Hence, the key element of the derived algorithm is the coupling of those fields. With the optimization result at hand, a rotor design is developed and validated using COMSOL Multiphysics®. Furthermore, a prototype is set up and tested experimentally. Finally, the simulation and experimental results are compared and evaluated.

Parallel Session
NVH Analyses

The elimination of dominating noise from engines and multispeed transmissions in electric vehicles creates the need for new NVH concepts. In this session, we show how mechanical vibrations and sound waves in electric vehicles are analyzed. Submodels are used to optimize the design at a component level when studying vibroacoustics problems.

Thermal Management

Thermal management is an important aspect across different automotive applications. Within vehicle electrification, thermal management is crucial, since batteries, fuel cells, and many other components produce heat and must be cooled as they work best within narrow temperature intervals. In this session, an overview of the features and benefits offered by COMSOL Multiphysics® to model thermal management of systems through convection and conduction will be demonstrated and presented. In particular, a demonstration of forced convective cooling will be shown.

Tech Café: Optimizing Fuel Cells, Batteries, and Supercapacitors for Automotive Applications

Understanding processes, testing new ideas, and virtually prototyping new designs are all within the wheelhouse of performing simulations when developing new technology for the vehicle electrification industry. However, once certain designs and desired performances have been decided upon, optimizing such to ensure maximum performance and quality is also important, and draws largely from the use of simulation. In this Tech Café, we will discuss how to use numerical optimization techniques to improve components, processes, and operating parameters in electric-driven vehicles.

Panel Discussion
Panel Discussion: What Role Does Virtual Product Development Play in the Future of E-Mobility?

There is no longer any doubt that future mobility will be electrically driven. But what role does virtual product development play on the way there? How can existing bottlenecks be overcome? How does modeling fit into existing or rethought development processes? Join the panel discussion to learn more about these key questions from the perspective of leading industry professionals.
