Advanced Lithium-Ion Battery Simulation Tools Available
Detroit-based CD-adapco is promoting methodology making it easier to design lithium ion battery packs, thereby “enabling faster design and development of advanced electric drive vehicle power systems.”
The technology has been incorporated in CD-adapco’s flagship STAR-CCM+ and in its application specific Battery Design Studio tool.
“These solutions provide seamless integration between electrochemists and thermal engineers within the battery design process,” the company says, by “linking the flow, thermal and electrochemical simulations into one environment.”
The CD-adapco work was supported by the U.S. DoE through the National Renewable Energy Laboratory – specifically CAEBAT, the Computer-Aided Engineering of Electric Drive Batteries initiative launched by DoE in 2010, CD-adapco says. The project team included CD-adapco, Battery Design Inc., Johnson Controls and A123.
Physics-Based Models, Linked
“Developing and linking physics-based models of batteries allows developers and designers to better understand the internal behavior of batteries in electric drive vehicles and explore new designs in a virtual environment,” NREL energy storage group manager Ahmad Pesaran says in a CD-adapco release, “reducing the number of prototypes and tests required by a traditional build-break design cycle.
“The outcome of this project is expected to enable scientists and engineers to further improve the performance, cost, and lifetime of advanced lithium ion batteries,” Pesaran said.
“These technologies have helped us design innovative battery systems and enable new fuel-saving technologies for vehicles,” said Brian Sisk, director of controls and modeling at Johnson Controls.
