Ansys, According to a release from the company, the team's efforts have led to the standard inclusion of battery models in the latest release of Ansys Fluent software, which is a significant milestone in advancing EV design efficiency.
Ansys said that over the last two and half years, the team worked on a DOE-funded project, Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT), to combine new and existing battery models into engineering simulation software to shorten design cycles and optimize batteries for increased performance, safety and lifespan.
The team is modeling thermal management, electrochemistry, ion transport and fluid flow.
As a result of the work, a battery model is now standard in Ansys Fluent, a computational fluid dynamics solution.
"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," said
By drawing on an approach pioneered at NREL, a DOE national laboratory, collaborators integrated disparate physical battery scales (electrodes, cell, pack and full vehicle) and multiple physical phenomena (electrochemical, thermal, fluid and structural) - factors that have been a key barrier for effective simulation. In addition, the team blended established detailed 3-D field simulation technologies with systems-level simulation.
"Ansys is well known for providing reliable simulation technology to enable sustainable design across a wide range of industries, including automotive," said
Throughout the remainder of 2014, the team will refine automation techniques for battery cell and pack-level simulations and continue to validate the models with experiments.
GM awarded Ansys a subcontract to create battery software tools that will help accelerate development of next-generation EV batteries.
This U.S. DOE-funded project is a result of a competitive procurement through NREL that was presented to GM in 2011.
This activity is part of the DOE EV Everywhere Grand Challenge managed by the
Ansys provides technology that enables organizations to predict whether their products will thrive in the real world.
