Endeavour is the first fully functioning, 100% solar-powered car raced by Georgia Tech. Silicon solar cells (17% efficient) are attached to the top of the aerobody made from carbon fiber. A steel chassis protects the driver and acts as the frame that holds it all together. Endeavour weighs in at a little less than 900 pounds with driver and has seen top speeds of 45 mph. All of this runs on about 1.0 kW, or roughly the same power as a hair dryer. In the past year, we improved most of the electrical communication systems in order to add CAN bus communication (replacing a single micro controller with many integrated micro controllers). We also improved the energy density of the batteries and updated the battery management system circuit board. The team is currently using Endeavour as a testing bench to validate all of the new and exciting technology we will be implementing on SR-2!
We are currently in the middle of construction of our next car, SR-2. This vehicle is designed to be compatible with rules and regulations of both the American Solar Challenge, as well as the World Solar Challenge, putting our team in a strong position for the future. According to our current plans, SR-2 will have an aluminum 6061-T6 frame, carbon fiber aerobody, a Kevlar battery box, lithium iron phosphate batteries, two 98.4% efficient motors, state-of-the-art solar racing tires, carbon fiber wheels, and 20.9% efficient single junction solar cells generating 1.2kW of power. We expect it to weigh around 600 pounds with driver (1/3 of the weight of a smart car) and to be capable of traveling as fast as 80 miles per hour. With the help of our sponsors and our experienced team, we hope to lead the way in student-run solar powered racing technology.
