Market shares of Plug-In Electric Vehicles (PEVs) which include Plug-in Hybrid Electric Vehicles (PHEVs), Extended Range Electric Vehicles (EREVs) and Battery Electric Vehicles (BEVs) continue to grow rapidly with global sales for 2016 expected to exceed 700,000 units largely due to strong growth in China, Europe and the United States.
Three main topical areas were identified, covering electrified powertrains, energy conversion devices and vehicle optimization. At the onset of the project, the impact of powertrain options, component sizes and technology alternatives on energy, cost and GHG will be evaluated for specific driving patterns both in the U.S. and China based on consistent vehicle technical specifications. High-efficiency engine combustion system options including advanced spark-ignition engine concepts as well as low temperature combustion systems will be evaluated accounting for regional usage patterns while adhering to market-specific constraints such as available fuel options and blending practices. Vehicle lightweighting research will be focused on design methods as well as the coupling of battery crash protection and vehicle lightweight requirements. Benchmarking of Chinese as well as U.S. selected advancing electrified options forms the basis for the definition of powertrain requirements, serving to validate sizing results and providing critical input into design and development of a high-efficiency PEV evaluation platform ultimately also helping to inform vehicle electrification policies.
