Better Tools for Designing Electric Vehicles Is Developing

US-based engineering simulation software developer ANSYS in association with the General Motors (GM), National Renewable Energy Laboratory (NREL) and ESim is working to design better, safer and longer-lasting lithium-ion batteries for electric vehicles (EV).

The team has worked to include the battery models in the latest release of ANSYS Fluent software, which is claimed to improve EV design efficiency.

The consortium has been working for over two and half years on a DOE-funded project, Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT), which combines new and existing battery models into engineering simulation software.

With the combination of battery models the companies aim to shorten design cycles and improve battery performance, safety and lifespan.

General Motors vehicle systems research lab director Jan Aase said the emphasis in the software integration has been to provide a flexible array of modeling choices that can support several categories of battery researchers, cell manufacturers, pack integrators and vehicle manufacturers that deliver fast and accurate results.

"With a concise plan for rapid deployment to the industry, the software solutions created through this project are already helping designers and engineers at GM to accelerate the pace of battery innovation and development for future electric-drive vehicles," Aase added.

The team has used thermal management, electrochemistry, ion transport and fluid flow to develop a battery model that is now standard in ANSYSFluent.

ANSYS global automotive industry director Sandeep Sovani said, "We are partnering with other recognized leaders in EV battery technology to develop and deliver powerful modeling tools that can be used by all battery manufacturers to accelerate production of safe, reliable, high-performance and long-lasting EV batteries that make vehicles more fuel-efficient and sustainable."

The team is also planning to refine automation techniques for battery cell and pack-level simulations and continue to validate the models with experiments through 2014.
