move freely between the development teams. nalized by Progress made by one stakeholders. team must be seen and interall Separate research, design, and engineering methods of the past will not achieve the speed of innovation required. Emerging technologies for unified demodeling sign and and simulation (MODSIM) enable collaboration between vehicle designers and battery engineers throughout the development cycle, from chemistry and materials to cell and pack design to vehicle integration and vehicle performance analysis. Realistic virtual testing with multiphysics simulation enables design and engineering teams to evaluate more material and design alternatives to achieve optimal solutions more rapidly. For example, to accurately model and simulate battery swelling requires tight integration between science and engineering disciplines and virtual Battery & Electrification Technology, December 2022 tools. The multidisciplinary nature of battery development pushes unified design and MODSIM to a new level, as the battery and EV chassis become integrated as one unit in a way never possible with combustion vehicles. Connecting the Development Stages with a Digital Thread Demands for improved safety, energy density, and battery lifetime require the chemistry of new materials to be explored, such as new electrolyte formulations and Exploded view of battery module and pack design integrated into a vehicle chassis.
