Yacinthe, S., Khanna, A., Ward, J., Yatsko, M. et al., "Development of the Design of a Plug-In Hybrid-Electric Vehicle for the EcoCAR 3 Competition," SAE Technical Paper 2016-01-1257, 2016, doi:10.4271/2016-01-1257.
The design of a performance hybrid electric vehicle includes a wide range of architecture possibilities. A large part of the design process is identifying reasonable vehicle architectures and vehicle performance capabilities. The Ohio State University EcoCAR 3 team designed a plug-in hybrid electric vehicle (PHEV) post-transmission parallel 2016 Chevrolet Camaro. With the end-goal of reducing the environmental impact of the vehicle, the Ohio State Camaro has been designed with a 44-mile all-electric range. It also features an 18.9 kWh Li-ion energy storage system, a 119 kW 2.0L GDI I4 engine that runs on 85% ethanol (E85) fuel, a 5-speed automated manual transmission, and a 150 kW peak electric machine. This report details the design and modeling process followed by the Ohio State team during Year 1 of the competition. The process included researching the customer needs of the vehicle, determining team design goals, initial modeling, and selecting a vehicle architecture. The focus will be on the initial analysis performed to narrow the design space, the tools developed for this analysis and the overall architecture selection process. This effort was made possible through the support of the U.S. Department of Energy, General Motors, Argonne National Lab, The Ohio State University, and numerous competition and team sponsors.
