Mechanical Design Guidelines of an Electric Vehicle Powertrain

Abstract

The tendency of alternating fossil energy sources with state-of-the-art renewable energy resources is spreading in most contemporary fuel consuming applications, and transportation, as one of the essential human needs, is not an exemption. Electric mobility is becoming more popular and practical day by day. Despite the recent advancements in electric vehicle technology, this state of the art is facing many challenges and requires further development. Improving the efficiency and finding new solutions for upcoming needs with a sustainable design methodology will enhance the progress in this field. Specialized and solitary improvement in this field may lead to weakening the overall efficiency and performance of the electric vehicle. Hence, the objective of this study is to develop a comprehensive approach that considers various aspects of electric vehicle driveline technology consistently in order to simultaneously satisfy different needs. In this dissertation, a multidisciplinary approach is presented for an electric powertrain design process, which covers the initial design optimization as well as evaluating the design endurance and performance. Theoretical and numerical methods, as well as the simulation tools, are applied in order to initiate and validate each design step. Different kinds of electric vehicle application—transportation, high-performance racing, and agriculture—are benchmarked by the presented methodology. Finally, both the study’s accomplishments and findings verify the proposed methodology and ensure both a reliable platform and path of action for future developments in electric vehicle driveline design technology.
