Our Goal

• The goal of our IPRO was the design and
  simulation of an Ultra Capacitor interface
  circuit for regulating power to a hybrid-electric
  vehicle.

3
What is an Ultra Capacitor?

• Also known as an electrochemical double-layer
  capacitor
• Based on polarization of an electrolyte, high
  surface area electrodes, and extremely small
  charge separation

Circuit Simulation

• Need Modeling Program Before Prototyping
• Future Compatibility
• Possible integration with other teams
  simulations
• Component Selection
• Allows the change of specs without new physical
  parts
• Error Detection
• Can find and solve errors before final build

Results and Problems

• Getting Program to Run
• Obtaining Software
• License Issues
• Complex Program
• Difficult but possible to integrate with C
• Limited help resources
• Integrating control issues
• Simulation Results

10
Difficulties

• Getting started and determining expectations for
  the project.
• Getting everyone up to speed on the IPRO, the
  technology involved, and the status of the
  development.
• Using SIMPLORER software for our simulations.
• Extremely electrical nature of our project made
  project difficult for students from non-related
  majors.

11
Interprofessional Aspects of our project

• Coordinating with IPRO 326 for future integration
  of our work.
• Working with Ansoft Corporation and IIT graduate
  students in working towards simulation of our
  design.

12
Benefits

• Reduced fuel consumption
• Environmentally friendly
• 1/3 the weight of lead-acid batteries, over three
  times the life
• Do not require maintenance
• Eliminates complication of charge circuits
• Higher power densities
• Have excellent low-temp characteristics
• Provides consistent performance over time

13
The Future

• Determine the feasibility (Cost Accessibility)
  of obtaining the components needed to create this
  power system.
• Develop a working Prototype of the System
• Test the system within the simulation of the
  hybrid vehicle of the other IPRO
• Test the system within an actual vehicle,
  ascertaining the actual improvement provided by
  the system as compared to theoretical and
  controlled environment tests.
