GM awarded ANSYSa subcontract to develop battery software tools that will help accelerate development of next-generation electric vehicles (EV). The project is a result of a competitive procurement through the DOE's NREL that was presented to GM last year (http://www.nrel.gov/news/press/2011/1472.html).
The main goal of the CAEBAT project is to incorporate existing and new battery models into engineering simulation software to shorten design cycles and optimize batteries for increased performance, safety and life span. The project is driving EV innovation.
The GM-ANSYS-ESim team's achievements over the past year include prototyping and validating three electrochemistry modeling approaches. The partners also prototyped a co-simulation feature, which blends battery multiphysics and system simulation technologies that enable engineers to shed unnecessary details and increase simulation efficiency without compromising the accuracy of the model.
"Traditionally, the EV battery industry depends mostly on the expensive and time-consuming process of design-build-test-break for prototyping and manufacturing these batteries," said
The team is leveraging NREL's considerable experience in multiphysics, multi-scale modeling of lithium-ion battery systems. The resulting design tools will be made commercially available through ANSYS. GM plans to validate and apply the model to its electric vehicles in development.
"ANSYS is well known for providing reliable simulation technology to enable sustainable design across a wide range of industries, including automotive," said
NREL expects that the resulting systems will become commercial offerings in about two years. This initiative is funded by DOE's Vehicle Technologies Program in the
