Technical feasibility study of a purely electrically driven taxi fleet

The research project ZENEM was designed to investigate the effects of future electric taxis on the distribution grid of Vienna for different feasibility scenarios. The analysis is based on measured preloading of different low voltage grids as well as on GPS-based, historical mobility data of a whole Viennese radio taxi fleet. These data characterize together with the selected charging infrastructure and electric vehicle characteristics the considered scenarios. This article describes the development of the individual scenarios and the impact on the distribution grid and further gives an outlook on the planned implementation.
