  2. Outline • The project • Components • Where we stand • Budget • Sample Calculations • Data Tables • Graphs • Timeline • What’s Next? • Conclusion

  3. The project • Convert gasoline motorcycle to electric • Emissions • Energy crisis • Ideal for short commutes. • Create publicity for the school. • Outreach • Open house

  4. Components • Batteries • 4-12VDC sealed lead acid • Designed for electric vehicles. • electricmotorsport.com • Charger • Soneil 48 V 5 amp • thunderstruck-ev.com

  5. Components (continued) • Motor • Briggs and Stratton Etek-R • 8 hp continuous • 15 hp peak • Controller • Sevcon Milipack • Regenerative • 48VDC • Wiring, fuses, throttle • electricmotorsport.com

  6. Where we stand • Motor kit & Batteries Purchased and received • electricmotorsport.com • Purchased motorcycle • Lemon and Barrett’s • Still need parts • Chain • Sprockets • Charger • Miscellaneous

  7. Budget Table of budget breakdown

  8. Sample Calculations Aerodynamic Drag Force (Fd): Cd= Coefficient of drag of the vehicle A= Frontal area of the vehicle in square feet V= The vehicle’s speed in mph Rolling Resistance (Fr): Cr= Rolling resistance factor W= Vehicle weight in lbs Force due to Acceleration (Fa): Ci= Unit conversion factor W= Vehicle weight in lbs a= Acceleration in mph/second Force due to Climbing Hills (Fh): W= Vehicle weight in lbs Φ= Angle of incline

  9. Sample Calculation (continued) Total Force on the Vehicle (FT): All four forces added together The Horsepower needed (hp): FT= Total Force in lbs V= Speed expressed in mph Torque needed from the Motor (T): hp= Horsepower RPM= Revolutions per minute Conversion from hp to Watts (W): Current needed to Power in Amps(A): V= Volts from the battery W= Power need to run in Watts

  10. Sample Calculations (continued) Time in hours the Vehicle can run (Time): Ah= Amp-hours from the battery A= Current Total Distance in Miles Vehicle can Drive (D): mph= Speed in mph Time= Time in hours vehicle can run Battery Charging Time (Tc): Ah= Amp-hours from the battery Amp= Amps from the battery charger

  11. Data Tables Table of various resistive forces with a constant acceleration of 3 mph/sec and a 3% grade.

  12. Data Table (continued) Table of Distance and other parameters with varying accelerations

  13. Data Tables (continued) Table of Distance and other parameters with varying inclines

  14. Data Tables (continued) Table of distance with a period of acceleration followed by a period of constant speed.

  15. Graphs

  16. Graphs (continued)

  17. Previous Designs • Very similar • Motor • Batteries • Type of bike • Verified project calculations • Made in home garage. • Proves feasibility • Total project costs less than $3000 Picture of bike that uses the same motor and type of batteries as this project.

  18. Current Timeline

  19. What’s Next? • Bike preparations • Layout of components • Bike Design • Assembly • Wiring • Testing • Demonstrations

  20. Conclusions • The design is feasible • Some minor funding is still needed • The project is coming along pretty well according to the plan. • The preliminary research and calculations are complete. • The bike is ready to begin laying out the components.
