Oregon High School Solar Car Team

Heliocentric

History of our Car

Heliocentric was built over a period of three years. Most of the work for this car was done during 2012.  Oregon State University has been a big help to our team. They designed the outside, bubble, part of our car. OSU let us borrow the molds for this part of the car. With the help of OSU and LancAir, we were able to make this part of our car out of Carbon Fiber. The Team then worked together to design mechanical and electrical components of the car to fit inside the body. Our Team worked on our car until the summer of 2012, when our team competed in The Solar Challenge at the Texas Motor Speedway in Dallas.

Mechanical Components of our Car

Frame- This is the composite structural part of our car. It keeps our car safe for the driver, as well as support the parts of the car.

Steering- This keeps our car going straight, or turning.

Brakes- These are extremely important. They make sure our car can stop in case of emergency.

Suspension- A rear swing arm keeps our drive wheel and motor in place on the car.

Electrical Components of our Car

 

The Solar Modules collect energy from the sun and concert it into electricity. This electricity goes through an MPPT, which ensures the correct amount of power is being transferred to the batteries. These batteries store the electricity, which we use to power our motor and move our car.

The Secondary Electrical System includes the lights, fans, horn and other seemingly nonessential electronics in the car. These components are actually all very important and we need them to make sure our car is road safe.

Composite Components of our Car

Both our frame and body are made of carbon fiber- a composite material primarily used in planes. Composites allow our car to be strong and durable while still lightweight and fast.
