Project Description

Founded in 1989, the Stanford Solar Car Project is an entirely student-run, non-profit organization fueled by its members’ passion for environmentally sustainable technology. We provide a unique opportunity for Stanford students to gain valuable hands-on engineering and business experience while raising community awareness of clean energy vehicles. The team generally operates on a two-year design and build cycle and enters the finished car in a cross-continental solar race.

Members usually join SSCP as undergraduates with little to no engineering background and gradually build their knowledge while working on a vehicle. Coordinating a project of this magnitude also requires considerable management and planning, allowing students to develop these vital business skills in an engineering environment. With this approch, the team has fostered nine generations of award-winning vehicles, proving that a hands-on education in creative design and execution produces impressive results.

Features

Our latest car, Xenith, was the first vehicle in solar car racing to use ultra-thin glass in the encapsulation of solar cells. This new method allowed for increased resistance to UV damage and efficiency equal to our bare world record efficiency monocrystalline silicon cells. Throughout the development of our car we strived to create novel designs and to find innovative applications of advanced technologies. Our unique suspension system allows all three wheels of our car to steer, allowing for reduced aerodynamic drag. Information for the drivers is integrated into a helmet mounted heads-up-display over the driver's right eye. Our battery pack gives our car a 200 mile range with no sunlight. With our telemetry system, any computer, iPhone, or other WiFi enabled device can monitor real-time performance data from the car. Every aspect of Xenith's design showcases the ingenuity of Stanford student engineers.

Our team is currently designing a brand new solar vehicle, and TI will continue to play an important role in our vehicle's electronics. TI's chips have many applications in our vehicle allowing us to design boards to control almost every electrical systems of the vehicle. Our solar cars have high powered systems for moving power from our solar array to our battery pack and to our motor. The vehicle's low current systems include driver controls, our telemetry system, tire pressure monitoring, lights, an IMU, and much more.
