Plugin Hybrid Electric Vehicles (PHEVs) have demonstrated the potential to provide significant fuel displacement across a wide range of driving cycles. Companies and research organizations are involved in numerous research activities related to PHEVs. One of the current unknown is the impact of driving conditions and standard test procedure on the true benefits of PHEVs from a worldwide perspective. To address this issue, Argonne National Laboratory (ANL) and IFP Energies nouvelles (IFPEN) have partnered under the IEA Annex XV task to evaluate the market specificities between Europe and U.S. Four different PHEV powertrain configurations with four All Electric Range will be analyzed under different standards (i.e., NEDC, UDDS, HWFET) and real world drive cycles (i.e. ARTEMIS…). The impact of different driving behavior for Europe and the US market will be analyzed through component sizing, fuel consumption benefits as well as Green House Gases (GHGs) considering the electricity production mix.The study will provide insight on how PHEVs can be designed to support worldwide market introduction of a limited number of vehicle options to maximize market penetration.

-Assessment by Simulation of Benefits of New HEV Powertrain ConfigurationsDuring the past couple of years, numerous powertrain configurations for Hybrid Electric Vehicles (HEV) have been introduced into the marketplace. The current dominant architecture is the power-split configuration with the input split (single-mode) from Toyota and Ford. General Motors (GM) recently introduced a two-mode power-split configuration for applications in sport utility vehicles. Also, the first commercially available Plug-In Hybrid Electric Vehicle (PHEV) -the GM Volt -was introduced into the market in 2010. The GM Volt uses a series-split powertrain architecture, which provides benefits over the series architecture, which typically has been considered for Electric-Range Extended Vehicles (E-REV). This paper assesses the benefits of these different powertrain architectures (single-mode versus multi-mode for HEV) (series versus GM Voltec for PHEV) by comparing component sizes, system efficiency and fuel consumption over several drive cycles. On the basis of dynamic models, a detailed component control algorithm was developed for each configuration. The powertrain components were sized to meet all-electric-range, performance and grade-capacity requirements. This paper presents and compares the impact of these different powertrain configurations on component size and fuel consumption.
