This paper investigates electric vehicle benefits and costs. Similar analysis could be applied to other alternative fuels. This study evaluates various types of electric vehicles. “Conventional performance” electric cars are intended to substitute for petroleum powered vehicles. However, for the foreseeable future they will fail to do this; electric vehicles offer significantly less performance...

Research Needs: Greenhouse gas (GHG) emissions from the transportation sector account for about 27% of the total GHG emissions in the United States. Due to increased travel demand and limited improvement in fuel efficiency, the GHG emissions from transportation have increased by 16% since 1990 (USEPA, 2015). About 80% of transit buses are currently powered by diesel engines, which are a primary...

This study investigated the heat problems that occur during the operation of power batteries, especially thermal runaway, which usually take place in high temperature environments. The study was conducted on a ternary polymer lithium-ion battery. In addition, a lumped parameter thermal model was established to analyze the thermal behavior of the electric bus battery system under the operation c...
