NEW YORK: CD-adapco has launched an engineering tool that will help manufacturers in the automotive and battery industries design electric power systems faster.

The STAR-CCM + Battery Simulation Module CAE tool simulates the flow, thermal and electrochemistry phenomena of spirally wound lithium-ion battery cells within one environment.

The project, which began in August 2011, is co-sponsored by the US Department of Energy’s (DOE’s) National Renewable Energy Laboratory and created in conjunction with Battery Design LLC, Johnson Controls Inc., and A123 Systems.

“The code includes some of the latest techniques for modeling electrochemical and thermal performance. It’s great to see these methods become mainstream,” said Battery Design LLC’s president Robert Spotnitz, a 30-year veteran of analytical methods applied to electrochemistry.

This computer simulation technology project was one of three chosen to support the DOE’s Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT) program to reduce petroleum consumption and greenhouse gas emissions.

DOE’s Office of Energy Efficiency and Renewable Energy provided the $7 million in funding to three teams, including one from EC Power, Penn State University, Johnson Controls Inc. and Ford; and another from General Motors, ANSYS, and ESim.

The teams contribute 50% of the project costs over three years bringing the overall project budget to $14 million.

Project goals include developing battery engineering tools to design cells and battery packs; validating the accuracy of those tools; shortening prototyping and manufacturing processes; improving overall battery performance, safety, and life; and reducing battery costs.

CD-adapco is a Melville, NY-based developer of engineering simulation software with 21 offices around the world.
