  1. Attributes of the Chevrolet Volt

  2. Attributes of the Chevrolet Volt

  3. VOLT Lithium-Ion Battery 288Cells 70% of the Cost Module Pack

  4. VOLT Lithium-Ion Battery

  5. The Battery Challenge • Lithium-Ion Battery Pack • 16 kWh (8kWh usable) • High energy/High Power • Efficiently packaged > 6 ft. in length > 375 lbs • Reasonable cost • 10 yr life/150,000 miles

  6. Early Vehicle Testing and Learning

  7. Next Phase of Testing and Learning

  8. Next Phase of Testing and LearningMule Vehicles now in Test

  9. Charging and Infrastructure

  10. Charging Power Level • 3.3 kW/240V charging will usually require a one time investment to upgrade the garage with a dedicated 240V circuit • Full charge is <3 hours – very acceptable • Fast charging will have customer value • 1.2 kW/120V charging may work depending on the customer’s situation • Full charge in minimum 8 hours (temperature dependent) • May require understanding and control of other devices on the circuit • Charger and control logic is on-board the vehicle • Designed for global voltages • 120V charge cord comes with the vehicle in NA

  11. GM / EPRI / Utility Collaboration • GM/EPRI/Utility Collaboration for Electrical Infrastructure • The Collaboration includes more than 40 Utilities in North America… many the industry’s thought-leaders in electric transportation and grid interaction

  12. Why collaboration is important?

  13. Impact on the Electric Grid Electricity: An important energy source with significant capacity to support transportation • 10 million E-REVs in 2010 would add a load that is less than 1% of the total grid load

  14. Electric Grid Design for Peak Demand The last 5% of the system’s capacity is needed less than 1% of the time The last 25% of the system’s capacity is only needed about 10% of the time The real objective of smart charging is simply to avoid these peaks with most of the vehicles out there This has tremendous value for the utilities – and very achievable once the technology is in place to manage vehicle charging For example, in California like most hot-weather states with a lot of air conditioning:

  16. 820 MILLION VEHICLES <1%are Electrified Vehicles (Hybrid, Battery Electric or Fuel Cell)

  17. Will Take>20 Yearsto ReplaceThem with More EnergyEfficient Vehicles

  18. NEW Propulsion Category Extended-Range Electric Vehicle E-REV
