Liquid Cooled Battery System
This project consists of designing, building and testing a fully functional lithium-ion battery system for the RIT Electric Vehicle Team’s next generation electric motorcycle. I was responsible for selecting the base cell, as well as designing the bus bars and cell connections. I am currently responsible for designing and building prototypes to validate current designs.
