Will people recharge a vehicle that does not have to be recharged? This, and the degree to which plug-in hybrid electric vehicle (PHEV) designs emphasize gasoline or electricity, are central to assessing the energy and environmental effects of PHEVs. Plug-in conversions of hybrid vehicles are...

This report provides an introduction to semiotics: the study of symbols and symbol systems. In particular, the report focuses on the symbolic meaning of automobiles, and explores why this meaning is important to consumers. Section 1 defines what a symbol is, identifies the types of symbols, and...

On July 22, 2002, Governor Gray Davis signed AB 1493 into law. This law requires that the California Air Resources Board (CARB) propose rules that would reduce greenhouse gas emissions of light duty vehicles in California. The goal of this study was to provide insight into industry and consumer...

This report discusses the development of advanced batteries for plug-in hybrid electric vehicle (PHEV) applications. We discuss the basic design concepts of PHEVs, compare three sets of influential technical goals, and explain the inherent trade-offs in PHEV battery design. We then discuss the...

Hybrid electric vehicles (HEVs) have image, or symbolic benefits, in addition to their functionality. This study examines the images that ten HEV-owning households saw in their vehicles, and the impact symbolic benefits had on these consumers' decisions to purchase HEVs. In general, all of the...

Presented at the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 The first step, in any program of self-improvement, is admitting you have a problem. My friends and colleagues, I would like to talk to you today about two big problems....

The notion persists that battery technology and cost remain as barriers to commercialization of electric-drive passenger vehicles. Within the context of starting a market for plug-in hybrid electric vehicles (PHEVs), we explore two aspects of the purported problem: (1) PHEV performance goals and...

This report examines early users’ experiences with plug-in hybrid vehicles (PHEVs). At the time this study was conducted in winter and spring of 2007, PHEVs were not yet commercialized. Still, Americans were becoming aware of PHEVs and 25 to 30 vehicles converted from hybrid electric...
