Electric vehicles and hybrid powertrains represent an opportunity for developing more adaptable and alternative transport solutions and responsible environmental strategies. Specific development of innovative vehicles and propulsion solutions in the case of road traffic aimed to improve the transport system and environmental protection as well as energy efficiency (to terminate gaseous emissions at road level) is significantly important due to the air quality improvement and pollution reduction in city areas. Energy management and efficiency digital control lead to an accurate carbon-footprint determination. The main objective of the research paper is to define some of the most important features in energy efficiency modeling and carbon footprint calculation for optimal transport management of an electric vehicle designed for city transport. Some specific characteristics and features in electric vehicle system modeling allow a certain control of significant parameters to increase the energy efficiency in order to diminish carbon footprint by using available tools from Automotive Department of Technical University from Cluj-Napoca. The work analysis some studies regarding the electric vehicle system, defines the opportunity for improvement, new technologies available to be used or implemented in the electric-vehicle systems, new features in the energy efficiency management, and generates results from modeling operational concepts. Defining and implementing innovative ideas regarding the software and hardware technologies is considered all the way in order to create and facilitate future development of the electric vehicle’s systems even with an increased energetic efficient propulsion plans for urban area in Cluj-Napoca.
