To Support Advanced Electric Vehicle Battery Systems Design, Altair, a global technology company providing solutions in product development, high-performance computing and data intelligence has announced the addition of the CellMod™ Virtual Battery by Sendyne to the Altair Partner Alliance (APA). So, CellMod™ Virtual Battery and BasicPackMod by Sendyne are now available for use by Altair HyperWorks™ customers.
CellMod™ is the first lithium-ion virtual battery capable of predicting cell and pack behavior, including thermal behavior, with an accuracy of better than 97 percent under a wide range of test conditions. Utilizing a sophisticated electrochemical model, CellMod is packaged as a functional mock-up unit (FMU), allowing it to be easily integrated into most major simulation packages, such as Altair Activate®, via the open industry standard functional mock-up interface (FMI).
After all, improving battery system performance is critical to facilitating the projected global electric vehicle market growth. An accurate battery model is the starting point for battery pack design, system control and optimization. The simple equivalent circuit (EC) models that are typically used today lack predictive power and are insufficient to the task. Taking a physics-based approach to simulating integrated systems that is accurate and runs faster than real-time can significantly improve the design of battery-based systems and optimize their long-term performance and safety.
Unlike EC models, CellMod accounts for physical processes taking place inside the cells, including diffusion in solids, diffusion in electrolytic solutions, reaction kinetics, charge transport, heat transport, etc. Because of this, CellMod can predict battery cell behavior with a high degree of accuracy.
