Range Anxiety, RekkEVidde or Plug-in Hybrid Vehicles

Facts about EV range

EV or Plug-in Hybrid?

TEMPO - 13. mai 2013 - Rolf Hagman rha@toi.no

what about range for the new evs
Whatabout range for thenewEVs?

Scientific aproach

Range is influenced by - drivingpattern (cycle), lowtemperature, rolling and air resistence (coastdown)

  • Normal temperature (+23 °C)
    • Air resistance for normal temperature
    • Road load for normal asphalt
  • Intermediate ambient temperature (-0°C)
    • Air resistance for intermediate temperature
    • Road load for normal asphalt
  • Low ambient temperature (-20 °C)
    • Air resistance for low temperature
    • Road load for normal asphalt
    • Road load for old snow
    • Road load for new snow

Results for one of the EVs Estimated driving range at -20 ºC (km)Driving – with battery heating 3 kWRange Anxiety at remote areas -20 ºC!!!

  • Measures to reduce range anxiety at -20 ºC:
  • Vehicleelectricpre-heating and liquidfuelcabinheater.
  • Or a plug-in Hybrid vehiclemight be the right choice?

  • In relation to today’scombustionenginevehicles
  • - realistictailpipe CO2 savings:
  • ”Power splithybridisation” (Toyota style) - 30 %
  • Plug-inhybridisation - 60 %

  • EV for short trips
  • Hybrid vehicle for long trips
  • No range anxiety
