ELaBoR - Infrastructure for car charging stations

Research project at a glance

The goal of this project was to develop a strategy in order to extend the infrastructure of car charging stations in Bonn and the Rhein-Sieg-Kreis.  Based on goals set by the government and information about the distribution of the car density in the area of interest, scenarios for the extension between 2016 and 2020 have been identified. In order to achieve these goals, the number of charging stations has to be raised successively from 256 (in 2016) to a number of 935 in 2020. Therefore, a grid map for the distribution of charging stations for electronic cars and bicycles had to be created. Also so called "points of interest" (POIs) (tourist attractions, leisure time facilities, etc.) as well as park-and-ride stations have been taken into account. All those options have been ranked according to their priority and their individual traffic data. The current distribution of charging stations has been investigated beforehand. With the help of an algorithm, the best positions and distributions for charging stations have been determined. Though, further analysis is necessary in order to bring these proposals into practise. Therefore, a guildeline has been developed and tested in a workshop for the locations "Königswinter" and "Bonn City Centre".

Project Description

The aim of the project was to develop a strategy for the successive development of charging infrastructure for electromobility in Bonn and the Rhein-Sieg district. Based on the expansion targets of the federal government for the charging infrastructure for e-cars and the vehicle density in the urban region Bonn-Rhein-Sieg, expansion scenarios for 2016-2020 were identified. In order to achieve the expansion targets, the number of charging stations to be installed must be successively increased from 256 in 2016 to 935 in 2020. The aim of the project was to create an optimal grid for the distribution of charging stations and to develop a systematic approach for a step-by-step expansion of the charging infrastructure with regard to e-cars and e-bikes.

The so-called points of interest (POIs) (tourist destinations, leisure activities, etc.) and park & ride lots in the city and district area were considered as potential location options. The site options identified in this way were classified according to their importance. They were then further weighted based on traffic data. In addition, a current survey of existing charging stations in Bonn and the Rhein-Sieg district was taken into account. With the help of an optimization algorithm, the optimal positioning and distribution of the sites was determined for each of the specified expansion targets. In order to arrive at a concrete structural and technical implementation of the charging infrastructure on the basis of the site proposals developed in this way, further analysis and planning steps are also necessary. To this end, a guideline was developed as part of the project and tested in a workshop using the example of two traffic cells (Königswinter and Bonn city center).
