1. 26. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport - Analysis of empirical data from North America

   Författare :Ahmet Mandev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eVMT; utility factor; charging behavior; fuel consumption; eVKT; greenhouse gas GHG emissions; PHEV Plug-in hybrid electric vehicle ;

   Sammanfattning : Plug-in hybrid electric vehicles (PHEV) can help reduce the greenhouse gas emissions in the transport sector, combined with the decarbonization of the electricity sector, and play an important role in electrifying personal transport. This thesis uses empirical data from North America to investigate the role of PHEVs in electrifying personal transport, with a focus on the household context and charging behavior. LÄS MER
