Sustainability in the car-based mobility: the case of the electric vehicle Editha

摘要

Purpose - Considering the well-known finiteness of resources and particularly in the light of previous concepts to ensure car-based mobility, this paper aims to outline to what extent the cost structure for sustainable mobility is still acceptable in the foreseeable future for the majority of people. The production and use of energy for mobility is a decisive factor for the future development of entire regions. This can be directly derived from the dramatically evolving energy cost in the recent years rooted in an increasing scarcity of known resources. Design/methodology/approach - On the basis of available new technology components, researchers from the University of Magdeburg (Germany) have converted a conventional car into an electric vehicle. Hereby, energy efficiency and sustainability were in the direct focus of the product redesign. Furthermore, a LCC analysis complements the qualitative analysis. Findings - Thus, a driving concept for electric mobility in the urban environment was drawn up which meets the criterion of suitability for everyday use due to an e-conversion. Moreover, the outstanding efficiency of the designed powertrain is demonstrated. Research limitations/implications - Using the research electric vehicle Editha, the researchers point out which technical options can be inferred from available components for the creation of mobility in the urban environment. However, the source of energy is crucial to assess if the claim for sustainability is fulfilled. Social implications - The paper illustrates that a monetary advantage of electric vehicles, such as the prototype Editha, arises after seven years due to disproportional purchase costs. Originality/value - In this context, the proposed driving concept of the prototype represents a transitional solution from vehicles with central engine to hub wheel electric engines. In addition, Editha is the first roadworthy and suitable for daily use research vehicle using an individual electric motor for each rear wheel without manual gearbox.
