Next-Gen CAE for Battery Engineering



Steering the Digital Future of Electric Vehicles

Electric automobiles are ushering in a new era of travel that is efficient, affordable, clean, and green. Bringing this new generation of cars onto the road requires new vehicle innovators and OEM leaders alike to rethink the way we experience their products, and the way they engineer them.

This is the case because batteries are one of the most important ways customers experience an electric vehicle. Therefore, their successful engineering is a critical industry challenge, and a hard one — they are highly complex systems requiring advanced engineering methods from chemistry to cell engineering to module and pack engineering, and finally to integration into full vehicles. They need to store as much energy as possible to allow for range anxiety to be contained while staying safe in case of unexpected events. Thankfully, there are exciting new ways for businesses to accomplish this.

No Time to Lose: The Innovative Race Is On

Battery development is incredibly complex and highly collaborative. In order to stay competitive, manufacturers can’t constrain themselves with legacy tools and methods that were made to address market realities of times past, especially when competing against rising, tech-savvy disruptors. They need new solutions that fully support today’s ambitions and processes, using modern-day technology to its utmost. Battery manufacturers need to be able to design, evaluate, and optimize their products in an interconnected, multidisciplinary framework.

CATIA, BIOVIA, and SIMULIA work together to bring a solution that truly connects mechanical and system design, materials and chemistry modeling, and performance assessment of battery cells, modules and packs.

3D Thermal Analysis of Li-ion Battery Cells with Various Geometries and Cooling Conditions Using Abaqus

Modeling thermal behavior of Li-ion cells for vehicle electrification applications is a challenging task. AVL has developed 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with various geometries using Abaqus. The 3D electro-thermal model employed in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.



Multidisciplinary Parametric Optimization of Cooling Channel Cross-Section for Battery Thermal Management

In electric vehicles, the battery thermal management system (BTMS) plays an important role in driving the battery performance. Most BTMS have a liquid cooling system, for which the performance of the liquid cooling channel continues to be a challenge. This study focuses on parametric optimization of the cross-section of the cooling channel using computational fluid, thermal, and structural analyses.



A Study of a Reduced Model of a Battery Cell for Structural Analysis

The battery pack is one of the core components in an electric vehicle. However, there are few papers that describe how to model battery cells at the battery pack level and the assembly level. The size of the battery pack model becomes very large when a detailed jelly roll model is used. The goal of this study is to develop a reduced model of a battery cell for structural analysis which also can be used at the assembly level.



Building Better Batteries

Romeo Power Technology, a California-based battery manufacturer, illustrates how SIMULIA Abaqus helps them tackle numerous challenges as they design the next generation of batteries to meet challenging new market demands, including automotive ones.


There are multiple challenges in the battery industry right now, and as a structural engineer, I need to focus on all of them. Abaqus software has become an invaluable tool for simulating and optimizing our battery designs, allowing us to effectively address each of these needs.
