Key terms used in the Automotive Climate Tool are defined below.

  • BEV = Battery electric vehicle: A vehicle operating solely on an electric motor instead of an internal combustion engine.
  • FCEV = Fuel cell electric vehicle: A vehicle powered by a fuel cell, typically using hydrogen as fuel, to power an onboard electric motor.
  • ICE = Internal combustion engine: An ICE vehicle is powered by a combustion engine powered by fossil fuels (e.g. gasoline or diesel).
  • PHEV = Plug-in hybrid electric vehicle: A hybrid vehicle combining an internal combustion engine with an electric motor whose battery pack can be recharged by plugging a charging cable into an external power source. PHEVs are not included as zero-emission vehicles, as they produce CO2 tailpipe emissions when not in all-electric mode.
  • ZEV = Zero-emissions vehicle: A vehicle that produces no CO2 tailpipe emissions, including battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs).
