The main target of the study was to perform a life cycle assessment of a Prius PHEV by Ga Bi modeling.The ANL model was used to simplify the functional unit and the process of Ga Bi modeling in material production, while the Ga Bi modeling was used to analyse some specific processes during the component manufacture unavailable in GREET 2.The assembly, use and repair phase were also investigated. The results revealed that the use phase accounts for a majority of energy use and emissions which result from fuel combustion and electricity generation for charging the batteries. Mineral resources consumption are dominated by material production. Besides, the Ga Bi modeling helps to improve the accuracy of CO2 emission calculation during the component manufacture about 17.39%.
