Abstract
Road transport significantly contributes to environmental issues. Efforts to reduce transport emissions include deploying electric vehicles and designing their powertrains for improved performance. This paper presents preliminary results of a novel functionally integrated electric axle (e-axle) developed within the EU project FITGEN. Using the Life Cycle Assessment method, the environmental impact of the FITGEN e-axle compared to the 2018 State-of-the-Art was assessed. Results found that the FITGEN e-axle reduced climate impacts and energy use by 26% and 38%, respectively. It also found critical aspects from an ecodesign and life cycle viewpoint: the improvement of components efficiency, the reduced usage of electronics due to component integration, and the use-phase electricity source. Thus, car industries may consider these aspects for improving the performance of electric powertrains.
