2.12: Power Integration for a Solar Car Sponsored By: Nathan England of Texas State University Project Manager: Isai Hernandez Austin Block & Kyle Fishbeck PM starts presentation. Everyone speaks. You decide who goes when.

Project Overview We were tasked with building the power integration system to be implemented in a solar car. This system consists of A solar controller to control when to charge the batteries and when to not A motor controller that will control the output of the motor based upon a throttle position sensor Give a brief overview of your project, like a very concise executive summary. # 2.12: Power Integration of Solar Car

Project Motivation The problem: We want Texas State to compete in the ASC! Need to go green! Brings in interest from prospective donors and students! Why are you doing this project? What’s important / needed / beneficial about it? Why is this a good senior design project? MAKE FONT BIG # 2.12: Power Integration of Solar Car

Top-Level (System) Block Diagram Show the top-level system diagram to put your design into context. Don’t make this too complicated! # 2.12: Power Integration of Solar Car

Design Block Diagram Solar Array Solar Array Controller Battery Pack Motor Controller/Driver Motor Solar Array Go through your Design block diagram. Blocks highlighted in yellow were designed by the team. Make the font BIG. You can’t spend more than 1 minute on this!!! Don’t make it too detailed. # 2.12: Power Integration of Solar Car

Results The Results: Motor Controller easily controlled motor with 144 V battery pack attached Able to have motor run at ~5000 RPM PWM controlled and completely isolated! Solar Controller able to switch on and off at 137.9V Reducing the power initially needed from 200W to ~160 mW Completely isolated! BRIEFLY summarize the results of your work – and what your design will do. USE GRAPHICS and PICTURES! Be visual!! Add slides if need be!! # 2.12: Power Integration of Solar Car

Future Work A DC to DC Converter is needed to step down high voltage, 138V, to usable voltage, 13.8V, for instrumentation. There will be other senior design projects to build the solar car. The power integration system is just the first step in building this solar car. Our project will be handed off to future senior groups to be implemented with their projects. BRIEFLY give 2-4 bullets of future work. BRIEF # 2.12: Power Integration of Solar Car
