Nikolaos Papadopoulos, Dr. Ing. h.c. F. Porsche AG
The increasing demand for sustainable mobility challenges the industry to develop high-energy lithium-ion batteries that meet long-range vehicle requirements and support fast charging times. Beyond efforts to enhance battery capacity and performance through cell chemistry and design, optimized operating strategies are essential for achieving fast charging. Electrochemical modeling enables the monitoring of internal cell variables, facilitating the development of fast-charging concepts that maximize cell performance without causing damage. Additionally, electrochemical modeling aids in conceptualizing cell design and enhancing understanding of ongoing processes in the battery's active materials.
Designing electric motors with high efficiency and power density is important for extending range and reducing battery capacity requirements. The COMSOL Multiphysics® software, along with its AC/DC Module, enables detailed modeling and simulation of electric motors as well as drivetrain technology, leading to improved designs.
For example, 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, making it indispensable to many R&D departments in the industry.
In this session, we will discuss the functionality of COMSOL Multiphysics® and the AC/DC Module and demonstrate how they can be used in the R&D of electric motors.
Tech Lunches are informal sessions where you can interact with COMSOL staff and other attendees. You will be able to discuss any modeling-related topic that you like and have the opportunity to ask COMSOL technology product managers and applications engineers your questions. Join us!
Dr. Reik Laubenstein, IAV Automotive Engineering Inc.
In automotive battery development, electrophysicochemical models (EPCMs) address the need for independence from assembled cell prototypes by providing high-fidelity simulated cell data. EPCMs can be used to benchmark different cell chemistries, designs, or performances, supporting development and optimization of functions, cooling concepts, and layouts, as well as safety evaluation. To fully leverage EPCMs, the data must be seamlessly accessible across other existing tool chains to foster acceptance and applicability within model-based development.
This presentation will focus on coupling pseudo-2D (P2D) cell models created in COMSOL Multiphysics® with modeling in other vehicle simulation environments such as GT-SUITE or Simulink®. Such coupling makes it feasible to investigate system-level impacts on the electrochemical behavior of these cells (i.e., performance and aging) while considering interactions over dynamic boundaries (e.g., temperature, coolant flow, and balancing).
Dr. Laubenstein will demonstrate the coupling solution's utility with two specific application examples. The first focuses on early detection of cell anomalies in a module by modeling different internal short-circuit resistances to mimic a faulty cell. The second focuses on thermal management of a battery and cooling system containing two substantially different next-gen cell chemistries: sodium-ion and solid-state lithium-ion cells in a "twin battery" concept.
Attend this session to learn how IAV uses the Application Builder and COMSOL Compiler™ to customize and compile multiscale battery simulation apps and then couple them with other vehicle simulation environments using the COMSOL Java® API in an integrated, model-based approach that enhances engineering effectiveness across all phases of development.
The use of modeling and simulation (M&S) is highly effective for studying the design and operation of battery systems. The COMSOL Multiphysics® software and its add-on Battery Design Module provide comprehensive and specialized functionality for describing batteries and electrochemical cells. The software also features multiphysics capabilities for coupling the electrochemistry within a battery with structural stress effects due to intercalation, heat generation, heat transfer, and computational fluid dynamics (CFD). Multiphysics models can be utilized to investigate thermal management and thermal runaway in individual cells as well as in battery modules and packs consisting of hundreds of cells.
In this session, you’ll learn about the capabilities of the COMSOL® software for modeling and simulating battery energy storage systems (BESSs) in stationary applications as well as battery cells and packs for automotive applications.
The widespread shift to green energy, including vehicle electrification, has increased the demand for power electronics devices such as power optimizers, 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 give an overview of how the AC/DC Module and Semiconductor Module are used for modeling and simulation of power electronics devices.
Nirmal Paudel, Veryst Engineering
Designing electric vehicle (EV) powertrains and motors is challenging given the competing requirements for energy efficiency, compactness, weight, thermal control, and other concerns. One enabling technology ideally suited to EVs is the axial flux motor (AFM). AFMs are electric motors where magnetic flux flows axially through the rotor, allowing for a more compact and lightweight design than traditional radial flux machines, as well as high-power density and efficient cooling. In this webinar, Nirmal Paudel will explore how to simulate an axial flux motor using the COMSOL Multiphysics® software. He will cover the steps required to compute torque, to calculate various losses (such as copper, iron, and stray losses), and to determine efficiency to understand the overall performance of the machine. He will work through an EV AFM example in detail to illustrate how these calculations, including static and transient simulations, can provide practical design and optimization insights.
The COMSOL Multiphysics® software provides comprehensive functionality for research, development, and design in the field of electrification. It offers efficient modeling and simulation capabilities for studying a wide range of physics phenomena, as well as features for creating standalone simulation apps.
The Application Builder and COMSOL Compiler™ enable larger groups of scientists and engineers to benefit from simulations through the use of standalone apps. The latest release of COMSOL Multiphysics® contains functionality for creating surrogate models trained on data generated from high-fidelity multiphysics models. Once trained, these surrogate models can be very compact and lightning fast, making them suitable for use in simulation apps and digital twins.
In this session, you’ll learn about the COMSOL® software’s capabilities for creating simulation apps and digital twins.
