摘要：To meet the targets of sustainable development and greenhouse emission reduction of the future vehicles fleet, the automotive industry needs to deploy cost-competitive and efficient advanced energy conversion systems for the future commercial personal vehicles. The efficiency improvement needs induce to search new structured methodologies allowing the integration of the efficiency/cost vision for different vehicle energy technologies, in the earlier design stage of the new vehicles and their propulsion systems. This article proposes a method to compare systematically different vehicles design options under different economic and environmental scenarios. The proposed methodology combines flowsheeting vehicles models, energy integration techniques, economic evaluation and life cycle assessment in a computational platform. The methodology is applied on electric vehicles and hybrid electric vehicles. This article presents the application of a systematic environomic optimization for vehicle energy systems. The efficiency, economic and environmental performances are assessed for different energy technology options and their integration in advanced vehicles powertrains. The performances indicators are compared and the trade-off are assessed to support decision making and to identify optimal energy systems configurations.
