Simulated thermal performance of battery packs. Cut cost, improved performance, and improved manufacturability of electric vehicles • Used MATLAB and STAR CCM+ to simulate Multiphysics problems, including heat transfer, fluid flow, and electrical. • Scripted in java to automate STAR CCM+ simulations, sweeps, and data post processing. • Reworked old MATLAB code into a new class, optimized code performance from O(n log n) to O(log n), created new methods / workflows for novel simulations and data post processing. • Used a state based modeling approach to model the vehicle and create firmware that runs in the physical vehicle. • Performed multi function optimization studies, cut 1kg of mass in a single study.
Powertrain Team: At my university's FSAE team, I improved the lap time by 4% (1500s to 1440s) from the 2019 to 2021 vehicle battery pack performance by optimizing the battery thermal management system. The previous generation (2019) battery pack would have ended the lap at 80 degC, 20 degC over the limit, and was developed without the use of a CFD model. I took the challenge to self-learn Ansys IcePak and built a detailed CFD model of the battery pack and thermal management system. Since CFD was new to the team, I wrote a 50-page document on model setup, including details of how translate fans curves and choice of turbulence models, for future reference. Using the CFD model, I identified that the fans could be positioned better to improve pressure drop (and thus increase flow rate by 50%) and found areas of low flow where baffles could be used to redirect flow. The final model showed the desired reduction in maximum cell temperature, down to 60 degC, without any cost, mass or packaging tradeoff. Composite Team: • Assisted with composite manufacturing to deliver a finished product at the end of the year. • Manufactured structural and aerodynamic components of the race car from composite materials such as carbon fiber and fiberglass. • Learned about various resins and layup techniques to construct components with the appropriate properties for their use case.
