Members of Task 15 met to plan the Task’s final report on its research into the technical and economic issues surrounding PHEVs on May 9–10, 2012. The meeting occurred directly after the 26thInternational Electric Vehicle Symposium (EVS 26) in Los Angeles, where members had presented several papers on Task 15’s work (listed at the end of this article).

Meeting participants discussed the structure of the Task final report that is scheduled to be presented at the IA-HEV Executive Committee (ExCo) meeting in October 2012. Some preliminary major findings include:

  • Parallel and input-split “blended mode” PHEVs with all-electric ranges from 15 to 50 km (9 to 31 miles) have been estimated to be the most cost-effective way to convert grid electricity to miles of vehicle travel for the lithium-ion battery technologies evaluated.
  • The broad success of battery electric drive vehicles requires the development of a next generation of battery technology/chemistries.
  • High fuel prices are important to the financial viability of and political support for electric drive.

Member countries are exploring whether to continue Task 15 after the final report is issued to the participating countries (Austria, Switzerland, and the U.S.) at the next ExCo meeting in the fall. If the Task continues into a new phase, further studies would address a number of topics that connect the technologies of PHEVs and other electric drivetrain vehicles with economic considerations such as cost, payback time, market size, and how they are used.

Task 15 members who attended included Mr. Dan Santini, the Operating Agent, and Mr. Aymeric Rousseau, Task 15 Vice-Operating Agent (United States), Argonne National Laboratory; Mr. Bernd Propfe (Germany), Institute of Vehicle Concepts at the German Aerospace Center; Mr. David Dallinger and Patrick Plotz (Germany), Fraunhofer Institute; Mr. Francois Badin (France), IFP Energies Nouvelle; and Mr. Joachim Skoogberg, (guest expert from Sweden), Vox Futura AB.

The University of California, Los Angeles (UCLA) Smart Grid Energy Research Center (SMERC) hosted the Task meeting. Meeting participants toured SMERC, whose research portfolio includes EV charging and its integration into the “smart grid” that adds communication technology to enable the electrical grid to connect a greater variety of power sources and user applications than ever before.

Prior to the meeting, Task members presented multiple papers based on the work of Task 15 at EVS 26, co-authors in bold are Task participants:

  • Fuel Consumption Potential of Different Plug-in Hybrid Vehicle Architectures in the European and American Contexts.  A. Da Costa et al. (F. Badin, A.Rousseau)
  • Cost analysis of Plug-in Hybrid Electric Vehicles including Maintenance & Repair Costs and Resale Values. B. Propfe et al. (D. Santini)
  • An Analysis of Car and SUV Daytime Parking for Potential Opportunity Charging of Plug-in Electric Powertrains. D. Santini, Y. Zhou, and A. Vyas
  • Vehicle Charging Infrastructure Demand for the Introduction of Plug-in Electric Vehicles in Germany and the U.S. T. Gnann, P. Plotz, F. Kley
  • Optimal Battery Sizes for Plug-in Hybrid Electric Vehicles.P. Plotz, F. Kley, T. Gnann
  • Effect of Demand Response on the Marginal Electricity used by Plug-in Electric Vehicles. D. Dallinger, M. Wietschel, and D. Santini
  • Impacts of PHEV Charging on Electric Demand and Greenhouse Gas Emissions in Illinois. A. Elgowainy et al. (D. Santini)
