  1. Pavan Kumar – 11/26/08, Can Ultracapacitors Save the Electric Car?

  2. Problem • 97% of Transportation dependent on gasoline • 60% is imported oil • Release 2000 metric tonnes • Less than 3% of the proven world reserves

  3. Background • Solution? • Possible Technical Issues • Horsepower • Range • Battery Life • Efficiency

  4. History

  5. Ultracapacitor Technology

  6. Comparision

  7. Advantages • Instanst Charge/Discharge • NO heat or Chemical RXN • No Overcharging • Long Lifetime • Operating Temp is -50C to 100C • No Harzardous Waste

  8. Application To Cars • More Power! • Reduced Battery Size – Design and cost • Regenerative Braking • Greater Efficiency – 14% • Load Leveling – absorb power during surges and discharge during dips

  9. Areas of Improvement • 1. Energy Density – Stand alone ultracap systems not possible • Cost – Can be 10x the cost of Batteries • Graphene • Graphene has a surface area of 2,630 square meters, almost the area of a football field, per gram of material
