Abstract
During 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.
