Evaluation environnementale du véhicule électrique : méthodologies et application

Abstract : Today, the electric vehicle is seen as a potent substitute to the internal combustion engine vehicle, aiming at reducing consumption of fossil fuels, and emissions of local pollutants and greenhouse gases. The assessment of strengths and weaknesses of this technology from the environmental viewpoint is currently limited, especially considering the lack of experiment feedbacks.The objective of this research is to offer an approach combining a deep understanding of the studied vehicle (through experiments and use of consumption patterns) and the environmental assessment method “Life Cycle Analysis” (LCA), to identify the key parameters of environmental appraisal, and relying on different sensitivity analysis, to propose a detailed analysis.To achieve this, experimental tests were carried out on an urban electric vehicle and its internal combustion engine equivalent. A model was built to estimate the consumption of electric vehicles according to their characteristics (chemistry and battery capacity, vehicle energy efficiency) and use (traffic, use of auxiliaries). Assumptions and scenarios are also made on the lifetimes of batteries in the vehicle. The data sets obtained are implemented in the life cycle analysis of an electric vehicle, and the results are interpreted and compared to its internal combustion engine equivalent vehicle. In the end, sensitivity analysis and test of various scenarios allow the identification of key parameters for the environmental assessment.
