The world is one step closer to more affordable and eco-friendly electric vehicles (thanks to the efforts of ANSYS (NASDAQ: ANSS), General Motors LLC, the Energy Department´s National Renewable Energy Laboratory and ESim, which are working to design better, safer and longer-lasting lithium-ion EV batteries.
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.
Over the last two and half years, the team worked on a DOE-funded project, Computer-Aided Engineering for Electric Drive Vehicle Batteries, 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 leading computational fluid dynamics solution. This seamless Fluent capability helps battery developers break the time-consuming cycle of design-build-test-break for prototyping and manufacturing.
By drawing on a unique 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. They also extended the reach of the technology by ensuring that these new tools can interact with current and future battery models.
