The California Air Resources Board has mandated that by 1998 2% of new vehicles sold in California must be zero emission, effectively, electric vehicles. This requirement is largely responsible for the electric vehicle development programs run by almost every global automobile manufacturer that does business in the United States. At present, no single electric vehicle technology, from battery type, to propulsion system, to vehicle design, represents a standard for a protoelectric vehicle industry. In this paper competing electric vehicle technologies are reviewed, leading public and private electric vehicle research programs worldwide are summarized, and the barriers faced by competing technological systems in terms of manufacturing and infrastructural requirements are examined.

The issue of energy economy in transportation has grown beyond traditional concerns over environment, safety and health to include new concerns over national and international security. In collaboration with the U.S. Department of Energy Office of FreedomCAR and Vehicle Technologies’ Working Group on Aerodynamic Drag of Heavy Vehicles, Argonne National Laboratory is investigating the accuracy of aerodynamic drag predictions from commercial Computational Fluid Dynamics (CFD) Software. In this validation study, computational predictions from two commercial CFD codes, Star-CD [1] and PowerFLOW [2], will be compared with detailed velocity, pressure and force balance data from experiments completed in the 7 ft. by 10 ft. wind tunnel at NASA Ames [3, 4] using a Generic Conventional Model (GCM) that is representative of typical current-generation tractor-trailer geometries.

The City

The growth of cities and populations has promoted the increase of income and consequently that of consumption. Some perceive growth in consumption as sign of a society´s development. However, upon analysis of the results arising from the increase of such consumption, it becomes apparent that it does spring both good and poor results, some of which might be irreversible. This consumption has been noted for expanding in both an unbridled and unsustainable manner, giving rise to damaging effects, particularly to the planet. An example of such rampant growth is that of the fleet of vehicles, which leads to increased traffic jams in the City that in turn generates pollutant gas emissions. Given this scenario, Collaborative Consumption - which in earlier days was solely perceived as a regular sharing mode (barter, loan, lease and exchange between people) - is currently being established and disseminated through social networks, mobile devices and geolocation systems, technologies which enable anyone to find available and globally shareable locations, products and services. This movement, which is ever gaining strength and character, alongside electric vehicle technologies, is capable of transforming businesses and the way a society lives and consumes, bringing to light the philosophy of cost reduction and the incentive for passive consumers to become active contributors of a sustainable technology. This study´s purpose is to understand the dynamics of Collaborative Consumption and the impact of adherence to this new movement, on Electric Vehicles.
