Concerns regarding air pollution, energy dependence, and, increasingly, climate change continue to motivate the search for new transportation solutions. Much of the focus is on light-duty vehicles, as they account for approximately 60% of transportation energy use and greenhouse gas (GHG) emissions. Battery-powered, electric-drive vehicles (EVs), such as plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs), are among the most promising of the advanced vehicle and fuel options that have been proposed to help reduce fuel usage and GHG emissions from light-duty vehicles.
