1. Project Umpqua Electric Vehicle Drive System Team Abdullah Binsaeed Dustin Buscho Steven Arlint Advisor Dr. Albright Industry Representative Mr. Menig Freightliner

2. Overview Introduction Scorecard Plans Milestones Issues/Concerns Conclusions

3. Introduction Light electric vehicle drive system –Driver and vehicle weight of approximately 450 lbs. –Commuters will benefit. –Main emphasis on the motor control and feedback –Displays data analogous to cars RPM and fuel gauge

4. Scorecard (DEC 05 plans) Test regenerative braking Full load test the forward drive mode of the motor controller Construct current sensing system Program PIC microcontroller to recognize the current sensing system Complete design review process (All of this has been completed)

5. Plans Finish PIC microcontroller programming for data acquisition Interface LCD display Complete Theory of Operations Document Test regenerative braking under load
