COMSOL Day: E-Mobility

See what is possible with multiphysics simulation

Components for electric vehicle (EV)-related applications, such as energy storage and drive systems or power electronics, can be better understood in early development phases using modeling and simulation. When used in the product design process, modeling helps to develop and implement innovative ideas and find optimal configurations.

In order to provide these benefits, the models used must take into account the multiple phenomena that may impact the performance of a process or device — in other words, they must be multiphysics models. In EV applications, for example, multiphysics modeling capabilities are essential to find and prevent hotspots in motors, understand the effects of mechanical loads on battery cells, or accurately model concurrent flows of liquids and gases in the porous electrodes of fuel cells.

This COMSOL Day will showcase the use of multiphysics modeling and simulation for the development and improvement of batteries, fuel cells, electric motors, and power electronics. Through technical presentations, COMSOL engineers and experienced keynote speakers from the industry will provide insights into the possibilities and how-tos of using multiphysics simulation for EV technologies.

Multiphysics simulation plays an important role in driving faster and more cost-effective research and development (R&D) in the e-mobility industry. This is mostly due to the fact that the design and development of electric vehicles involves electromagnetics, structural mechanics, heat transfer, CFD, and electrochemical phenomena — the ability to account for all of these phenomena in one model is critical. COMSOL Multiphysics® makes such modeling easy, and is widely used within this industry because of it.

In addition, with the Application Builder and Model Manager, users can create and distribute simulation apps, and can collaborate on apps, models, and simulations.

In this session, you will learn about current modeling trends at leading research institutes and industrial R&D departments within the e-mobility industry, and see how such trends are inspired or enabled by the use of multiphysics modeling and simulation apps.

The demand for and development of electric motors has increased exponentially, with hybrid and electric cars expected to make up a major portion of new car sales in the near future. Designing electric motors and drivetrains that maximize efficiency is crucial for increasing range and reducing battery capacity requirements. Modeling and simulation are integral parts of the R&D process for maximizing this efficiency, and COMSOL Multiphysics® and its AC/DC Module and Battery Design Module add-ons have become important tools for many R&D departments in the industry.

Electric traction motors also need to deliver high torque over a wide speed range while staying within temperature limits and allowing for efficient manufacturing. The most common types, synchronous permanent magnet and asynchronous motors — as well as more recently researched alternatives such as synchronous reluctance or axial flux motors — can be modeled and optimized in COMSOL Multiphysics®. The software's capability to effectively capture multiphysics effects and apply powerful optimization techniques has empowered designers to improve efficiency and decrease costs.

We welcome you to this session, where we will discuss these subjects and demonstrate how COMSOL Multiphysics® can be used in the research and development of electric motors and drivetrains.

The widespread shift to green energy and vehicle electrification has increased the demand for power electronics devices like power optimizers, a type of DC/DC converter used to maximize the power production of solar power and wind turbine systems. Power electronics include components such as converters, rectifiers, amplifiers, and switches.

The AC/DC Module and Semiconductor Module add-ons to COMSOL Multiphysics® provide specialized functionality for modeling these devices. In addition to enabling lumped circuit extraction, the software’s multiphysics capabilities allow users to include thermal and structural effects when designing integrated circuits and discrete devices such as metal-oxide-semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors (IGBTs).

Join us in this session to learn more about the capabilities of the COMSOL® software for modeling and simulating components in power electronics. We will demonstrate the use of the AC/DC Module by building models and running simulations of power electronics devices.

The COMSOL® software provides a purpose-built environment for high-fidelity modeling of batteries. With the Battery Design Module, users are able to define detailed models of battery cells and packs that include electrochemistry, material transport, heat transfer, fluid flow, and structural mechanics phenomena. Discharge–recharge cycles, aging, thermal management, and other processes associated with the operation of battery systems can be modeled using transient methods such as electrochemical impedance spectroscopy.

The latest version of the Battery Design Module features enhanced functionality for easy setup of battery pack models with hundreds of batteries. Each battery can be described by an individual electrochemical model that includes temperature effects. The new functionality enables a very efficient procedure for modeling thermal management and thermal runaway propagation in battery packs.

Join us in this session to learn more about how to set up models and how COMSOL® users have utilized the Battery Design Module in their studies of battery systems.

The Fuel Cell & Electrolyzer Module in COMSOL Multiphysics® expands 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 electrolyte-types, such as proton exchange membranes, alkaline, 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 in both fuel cells and electolyzers.

Modeling and simulation have been crucial for the development of the lithium-ion battery used for electric vehicles. With its high energy density, the fuel cell offers a future alternative for powering heavy vehicles like trucks in combination with batteries. Due to the narrow temperature interval of operation, thermal management is crucial for the design of these systems.

The Battery Design Module and Fuel Cell & Electrolyzer Module add-ons to COMSOL Multiphysics®, in combination with the Heat Transfer Module, offer a uniquely robust environment for modeling and simulation of thermal management. These tools can be used to account for heat generated by electrochemical reactions, Joule heating, conjugate heat transfer, evaporation, turbulent nonisothermal flow, and other coupled phenomena.

In this session, we provide an introduction to modeling and simulation of thermal management of batteries and fuel cells using COMSOL Multiphysics®. We demonstrate with models at the battery cell, battery pack, fuel cell unit cell, and fuel cell stack scales.

Battery systems are often burdened by unwanted side reactions at the electrodes. The Battery Design Module can be used to simulate various aging and degradation mechanisms and the resulting capacity fade in batteries.

Any arbitrary by-reaction, such as hydrogen and oxygen evolution, the growth of a solid electrolyte interface due to deposition, metal plating, metal corrosion, and graphite oxidation can be included in a battery model through the flexibility built within the Battery Design Module.

In this session, we will present and demonstrate the capabilities of this module to model degradation in batteries and the process of building and running a capacity fade model.
