Bicycle Powered Charger Kento Yamaguchi ECE 498 Design Defense Advisor: Professor Hedrick

Project Goals Generate and store enough energy to charge common small electronics. Motivate people to use their bicycle for health. Aggregate daily tasks by providing the user an alternative to charging their electronics and transportation.

Design Requirements Optimize the components of the system for maximum generated stored energy for minimum effort. Minimal interference with the normal function of the bicycle. Fit on any bicycle. Easy to attach and remove.

Top Level Design

Design Options AC or DC generator. Lithium Ion, Nickel Metal Hydride, or Nickel Zinc battery Generator placement: Gears for less resistance to the overall bike speed.

Testing plan Test the bicycle without the device for: time to complete a set distance distance traveled in a set time Test the bicycle with the device for time, distance, and energy produced. LCD display and circuit to monitor to show amount of energy in the battery Efficiency measurement: Power = torque * radial velocity Compare this power to what I actually get

Design Schedule TimePlan October 2015 Project presentation Get parts ordered Second grant period November 2015 Receive parts for project Test parts when they arrive Finalize paper and website for the project December 2015 Check up on parts that have arrived Think about how the device will be put together Winter Week 1 Test each part individually and gather information on their usage. Think about how to connect each part Winter Week 2 Apply for grants on parts broken while testing if necessary. Continue testing and make decisions on which parts to use based on their performance. Winter Week 3Find ways to connect the parts together in a way that will successfully draw energy from a bicycle and be comforting to the user as well. Winter Week 4Start testing the device on the bicycle Winter Week 5Complete tests on the bicycle Winter Week 6Think about what conclusions that can be made based on the whole design experience. Winter Week 7Work on design presentation and report based on testing. Winter Week 8Capstone Design Presentation Winter Week 9Work on final report based on testing Winter Week 10Deliver final report May 27, 2016Steinmetz Day FutureWork more on the project
