Dimensionierung des Ladeinfrastrukturbedarfs für Elektromobilität - Charging infrastructure dimensioning for Electric Mobility

Various factors require a fundamental change of our individual mobility behavior. These factors include among others the scarcity of fossil fuels like oil, environmental aspects and the increasing urbanization on a global scale. For this pur-pose different approaches will be examined. Electric mobility seems to be a serious alternative to vehicles with combus-tion engines. Various international research programs are currently being issued by several countries with the objective to foster the mass rollout of electric vehicles (EVs). On behalf of the Federal German Government, it is especially the National Electric Mobility Platform (NPE) that pro-motes this ambition in Germany. In the past two years, the NPE developed a recommendation regarding a nationwide introduction of electric vehicles [1]. In this context, it particularly discussed the question of necessary charging infra-structure that needs to be built to satisfy the charging demand of the increasing number of EVs in Germany. The main focus of this discussion is on the optimization of the three major challenges of reliability, vehicle operating distances and investment costs. This paper examines vehicle movement patterns with the objective to derive the optimal density of charging infrastruc-ture in urban areas. Based on simulated charging processes suitable locations for charging stations will be ultimately identified. The necessary charging station dimensioning will be performed in the following. The investigation is based on empirical data respectively movement pattern derived out of this data. The data can be scaled to future market trends.
