I interned at Lightening Energy researching mechanical and structural components for electric vehicles and their cost estimations. I got to learn about existing technologies for electric motors and transmissions, and analyzed their torque and power capabilities. This research was used for an electric-vehicle design and was incorporated into a report and pitchdeck that the company can present to investors. Through this project, I also learned about financial modeling and market considerations as they impacted vehicle designs. Besides this project, I got to use computational fluid dynamics (CFD) for a thermal coolingsystem design, and toured the company’s dry room where they make batteries. This internship allowed me to apply mechanical concepts I learned in class to product design and to gain valuable industry experience. It inspired me to choose a senior design project that involves mechanical design and prototyping, and to pursue a career in mechanical design.
