22 Jan 2009

JB Straubel, the CTO of Tesla Motors, gave a talk to a packed Stanford CarLab forum a few days ago. Some of the interesting tidbits from his presentation:

  • the battery pack in a Tesla roadster costs around $25,000
  • battery technology is improving at 8% per year in terms of gravimetric or volumetric energy density
  • there are approximately 12,000 fuses in the battery pack
  • in terms of well-to-wheel efficiency, electric cars can currency reach 85% efficiency.
  • hydrogen systems eke out 32% efficiency, through combined losses from electrolysis (70% efficient), hydrogen compression during storage (90% efficient), and fuel cells (50% efficient)
  • an acre of solar cells can take a car 36x the distance than an acre of ethanol
  • quoted Sheikh Yamani, a former Saudi oil minster stating “The Stone Age did not end for lack of stone, and the Oil Age will end long before the world runs out of oil.”
