  1. Chapter 19 Myth: Electric Cars Are the Next Big Thing by Jonathan Straetker

  2. Electric Car Hype • …”help the world end its addiction to oil by transforming cars from their climate-changing, lung-polluting, gas-guzzling design to one that’s clean, affordable and all electric.”

  3. Pros and Cons The Positives: • Low refueling costs • No air pollutants at point of use • Quiet operations The Negatives: • Limited range • Slow recharge rates • Lack of recharge stations • High costs

  4. 2009 DOE Energy Storage Report • Costs • “The current cost of Li-based batteries is approximately a factor of three to five too high a kWh basis.” • Abuse Tolerance • “Many Li batteries are not intrinsically tolerant to abusive conditions such as a short circuit, overcharge, over-discharge, crush, or exposure to fire and/or other high temperature environments.” • Life • “The ability to attain a 15-year life…or 5000 EV cycles are unproven and are anticipated to be difficult.” • Performance • “The performance barriers include the need for much higher energy densities to meet the volume/weight requirements…”

  5. Energy Density Data obtained from Sustainable Energy – without the hot air

  6. Future Vehicles • Electric powertrains with advanced energy storage technology (batteries and ultracapacitors) • Internal Combustion driven • Increase use of diesel
