Webinar Series: Recent Advances in Automotive Simulation
Automakers and suppliers around the world increasingly rely on ANSYS for single-physics and multiphysics simulation solutions, for both component and systems level analysis. Applications range from aerodynamics, underhood thermal management, IC engine, transmission, brakes, and chassis components to the entire electric powertrain including battery, traction motor and power electronics. In this webinar series, ANSYS shares the latest advances in automotive-specific solutions that allow companies to thoroughly explore design alternatives under varied, real-life load conditions early in the design cycle.
A Total Li-Ion Battery Simulation Solution
This presentation shows a complete model for an li-ion battery pack. It starts from the Newman electrochemistry model to create the battery performance curves. Such information is then used to create cell level battery equivalent circuit model (ECM). 28 cell ECMs are connected to create the module ECM. Four module ECMs are connected through a busbar model to create the pack ECM. The busbar model is a reduced order model (ROM) extracted from electromagnetics FEA solver, taking into account the parasitic effects. Battery thermal performance is first calculated by computational fluid dynamics (CFD). Then, a thermal ROM is created out of CFD solution. The thermal ROM is then two-way coupled with the battery pack ECM to form a complete battery pack model. Thanks to the ROM technology, such a battery pack model can finish a complete charge discharge cycle within seconds of simulation time.

Accelerating Development of EV Batteries Through Computer-Aided Engineering
Developing low-cost, high-energy, safe and long-lasting batteries is crucial for the wide adoption of electric vehicles (EVs) and ultimately reduces petroleum consumption and polluting emissions. Computer aided engineering (CAE) tools could accelerate the development, design, and prototyping of batteries. The Vehicle Technology Program in the Department of Energy has launched Computer Aided Engineering of Automotive Batteries (CAEBAT) to work with national labs, industry and software vendors to develop sophisticated software. The National Renewable Energy Laboratory (NREL) is the coordinator of the CAEBAT activity and is working with a number of companies, including ANSYS, to develop these models and tools to help improve and accelerate battery design and production.
Join us for this webinar in which we will present an overview of both CAEBAT and the Multi-Scale Multi-Dimensional (MSMD) model, a predictive computer simulation of Li-ion batteries. We'll also present results that show the utility of the model by the impact of design parameters on performance.
