  6. 6. Heating loads were significantHeating loads varied by driver.Heating loads varied by storage type(ie. heated garage, outdoors, etc.)Range started decreasing as soon asthe temperature was less than athermostat’s set point.The decrease in range followed thebow-tie analogy.

  9. 9. EVs are often initially Over 50 % of EVs expected to be sold inrolled out in warmer the US this year are located in the 17weather states hottest states.e.g. Nissan LEAF initial Drivers in warmer climates deservemarkets: consideration as well.• Arizona• California• Hawaii• Tennessee• Texas• Oregon• Washington
  10. 10. National Renewable Energy Laboratory (NREL)• Lab data on i-MiEV shows air conditioning reduces range from 34% to 46% depending on the mode Nissan USA • 70 miles: highway driving -32% at 95 °F (35 °C) -30% 100% • 68 miles: city driving at 110 °F (43 °C),Provides great data for the “worst case”. What about real-world operation?
