Topics of the Presentation . Historical context . Distinguishing among three major kinds of plug-in electric cars . Operations and infrastructure . What are the motivators for development and sales of plug-in electric vehicles? The first electric vehicles (EVs) . First crude electric made between 1832 & 1839 . More practical & successful vehicles made around 1842 . Better battery storage invented in 1865 with further improvements in 1881 Jay Leno’s Baker EV 1900s Markets Were: Where Garages Were for Personal Vehicles; Slow MPH Urban Delivery . (Midwestern) cities with lower density had higher EV car share – houses, more new construction . New York was the first city to lose all personal use EVs (multifamily, long commutes, hills) . New York City was the most successful location for truck fleet EVs by far (slow average speed, many customers, large fleets, long hours, used most available range or even more via battery swapping) . Taxi fleets were also tried (slow average speed, high value for clean and quiet) . Increasing power and speed of gasoline killed the EV. Hybrid Electric Vehicles have been around for years Hybrids have been around for 100+ years, and plugged in.

Maitra (Electric Power Research Institute). Plug-In Vehicle Drive Impacts to the Grid TRB Environment and Energy Research Conference June 7-9, 2010 Due to Costs of Trenching and Rewiring, Costs Behind the Plug Can Vary Significantly. New Construction Can Be Far Less Expensive, But Most Will Involve Retrofits. Most owners will charge vehicles at home, making Level 1 and Level 2 the primary options. Workplace seems to be the next highest priority. Level 2 charging equipment now costs $1,500 to $2,500 when owners choose to install. Old dwellings with limited kW capacity could require rewiring, or investment in much more efficient appliances and/or lighting to create capacity for the PEV. Level 2 at work is generally more expensive, with longer runs to parking spots, needing trenching and paving replacement. Each of these installations requires permitting and licensed contractors.

As the world needs more fuel-efficient vehicles to mitigate climate change, the role of HEVs and PHEVs are becoming ever more important. While fuel economies of HEVs and PHEVs are superior to those of internal combustion engine (ICE) powered vehicles, they are partially powered by batteries and therefore they resemble characteristics of battery electric vehicles (BEVs) such as dependence of fuel economy on ambient temperatures. It is also important to understand how different extent of hybridization (a.k.a., hybridization ratio) affects fuel economy under various driving conditions.

January, 2011 INTRODUCTION Advanced Manufacturing is a term without an exact or consistent definition. The proponents know it when they see it but often can’t define it. The definition is not commonly agreed upon, even in the manufacturing community. This ambiguity has hamstrung communities and states hoping to develop a strategy for promoting and growing Advanced Manufacturing. If you can’t define it, how can you identify and develop it? Most experts now agree on several points. First, advanced manufacturing isn’t industry specific, although some industries such as defense, aerospace, and automotive have more advanced manufacturing companies than others. Advanced Manufacturing is identified at the company rather than the industry level. It is more useful to define Advanced Manufacturing based on “how” companies manufacture, rather than on their end products. Since all of the economic and employment information for manufacturing is collected based on the finished goods that are produced, traditional industry statistics aren’t useful for identifying it.

Four key findings have been identified by the E-Truck Task Force as barriers currently affecting the growth and viability of E-Truck sales; 1) high incremental cost, 2) poor vehicle quality and support from supplier(s), 3) unexpected costs and energy planning with infrastructure, and 4) reduced operation in extreme climates. The E-Truck Task Force developed a set of action-oriented recommendations for overcoming each barrier. 1. E-Truck Task Force Background 1.1 Key Findings from 2012 E-TTF Report CALSTART’s E-Truck Task Force (E-TTF) was originally created in 2011 to help understand, support and expand the production and successful deployment and use of plug-in electric trucks and buses. CALSTART published E-Truck Task Force Findings and Recommendations in 2012 based on a year-long research and industry engagement process. In that report CALSTART outlined the best use profiles for successful E-Truck deployment, provided a business case calculator for fleets, highlighted early adopter user experience, developed an infrastructure planning guide, and then established industry recommendations of actions required to speed market success.

  • Sizing and Fuel Consumption Evaluation Methodology for Hybrid Light Duty Vehicles
    World Electric Vehicle Journal Vol. 4 - ISSN 2032-6653 - © 2010 WEVA Page000249 EVS25 Shenzhen, China, Nov 5-9, 2010 Sizing and fuel consumption evaluation methodology for hybrid light duty vehicles Nicolas Marc1,3, Eric Prada1, Antonio Sciarretta2, Shadab Anwer1, Franck Vangraefschepe2, François Badin1, Alain Charlet3, Pascal Higelin3 1 IFP Energies nouvelles, Rond-point de l'échangeur de Solaize, BP 3, 69360 Solaize, France ([email protected]) 2 IFP Energies nouvelles, 1 et 4 avenue de Bois-Préau, 92852 Rueil-Malmaison, France 3 PRISME/EPM, Université d'Orléans, 8 rue Léonard de Vinci, 45072 Orléans Cedex 2, France Abstract This paper presents a methodology dedicated to component sizing and fuel consumption evaluation of different degree of hybridization for light duty vehicles applications. The methodology will be described together with vehicle and components simulation and sizing principles. To ensure a systematic approach, with no bias for any of the cases considered, the energy management of the hybrid drivetrain will be carried out thanks to an optimization based on the Pontryagin's Minimum Principle. As hybrid fuel consumption is highly dependant on vehicle type of use, the hybrid vehicles will be evaluated on different actual use driving patterns as well as on missions representing the daily usage of the vehicle. The methodology and a panel of results are presented in the paper. Keywords: HEV, plug-in HEV, components sizing, energy consumption, simulation, optimized energy management 1 Introduction of map representations of the differently sized components (battery, electric HEVs are complex systems in which many machine, IC engine, etc.); parameters could impact the fuel economy potential and it appears that car and component 2.
