Plug-in Hybrid Electric Vehicle
Team Objective• To advance the development of an in house hybrid electric
vehicle for use in testing Dr. Dean Edwards' experimental lead acid batteries.
University of Idaho 2012 Capstone Design
Plug-in Hybrid Electric Vehicle
EE Specifications• Operational Electric Car
– Car Drives in a safe and reliable manner– Batteries can be charged from a 240V wall outlet
• Auxiliary Power Unit (APU)– Charges batteries– Is operated by a stand alone microcontroller
• Design Priorities– Safety– Functionality– Aesthetics– Cost

Electrical Final Achievements• Safety Features
– Fuses, Relay, Quick Disconnect• APU
– Microcontroller• Starts Engine• Gives Engine 2min warm up at 6,000rpm• Rev’s Engine up 12,000 rpm charging speed• Shuts off at user’s command
– Due to problems operating at 12,000 rpm tests were not conducted and a future team will be designing for more around 6,000 rpm.
• Car Drives!

Lessons Learned• Project Management
– Set “mandatory” work times throughout the week– Split tasks as either ME/EE/Both
• Dealing with Team Stress– Find humor in things gone wrong
• Keep the End Goal in Sight– Don’t get caught up in the little things
