Abstract

Sunswift IV is the UNSW Solar Racing Team's most recent solar vehicle, and their entry into the 2011 World Solar Challenge, a 3000km race from Darwin to Adelaide. In order to be competitive in this race, the team needed to improve the accuracy of the models and reliability of the instrumentation used in their strategy system, which is responsible for calculating the optimal speed at which solar cars run the race. During the course of this thesis, roll-down tests and analysis is carried out to model the mechanical systems of the car, and an accurate first-order model for the solar car battery is developed. The current integrator device, which measures the solar car battery state of charge, is redesigned, and generally performs well in bench and field tests. The accuracy of the mechanical model requires some improvement, and suggestions are made as to how to use the roll-down method in the future to do this.}
