Development of a methodology to determine NOx-saving-potentials through the buildup of public charging infrastructure for electric vehicles

Abstract

Nitrogen oxide (NOx) pollution in urban areas is increasingly becoming a problem for human health. Approximately 43% of NOx emissions in Germany are caused by road traffic. Especially in cities, road traffic is the main source of critical NOx concentrations. As a result of high traffic densities and the poor ventilation of streets due to narrow streetscapes, there often is insufficient diffusion of the NOx gas. The current market ramp-up of electric vehicles represents an opportunity to limit the negative effects of road traffic on the pollution especially in urban spaces. In order to further promote the market diffusion of electric vehicles, appropriate charging infrastructure for battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV) in the public road space is required. Mapping the impact of the development of public charging infrastructure on the local NOx-emission of the vehicle fleet is the aim of the developed methodology.
