Abstract : Development of an effective method for evaluation of alternative energy sources in the automotive industry has always been a necessity for cost efficient design analysis. One viable alternative energy source is electricity. In the present day environment of shrinking fossil fuel supplies and environmental awareness, electric powered vehicles are becoming a low cost, non-polluting, alternative means of transportation. The analysis of reliable electric propulsion can be expensive without a modeling tool for evaluating design strategies before vehicle construction. This thesis explores electricity as an alternative energy source for the automobile of tomorrow. Under the guidelines of the World Solar challenge, a solar powered electric vehicle, using a permanent-magnet brushless dc motor has be modeled and simulated in Simulink (Dynamic System Simulation Software). The simulations were performed with the goal of determining the optimum configuration to efficiently utilize the power supplied from the solar array, batteries, and motor. The simulated vehicle was 'driven' over various terrain's and at various speeds. The results obtained confirm this simulation as an efficient design tool and present an example of an optimum vehicle speed for one particular vehicle configuration.
