In order to achieve environmental goals, the electrification of vehicles will play an essential role. Electric vehicles (battery electric vehicles and plug-in hybrid vehicles) require sufficient public and private charging infrastructure. The city of Hamburg has already made an important contribution with more than 1,000 public charging points. Nevertheless, the charging infrastructure outside public spaces is important for the success of electromobility in Hamburg and is therefore supported with up to 7,400 charging points within the framework of the ELBE project ("ELectrifying Buildings for Electric Vehicles").
Project
During the previous phase of public charging infrastructure bulid-up in Hamburg, it became clear that the subjectively perceived availability of the charging infrastructure is decisive for the success of electromobility. Therefore, a charging infrastructure concept is being developed in the ELBE project as part of the “Residential Charging Real Laboratory” and will be tested in two districts.
The focus of the charging infrastructure concept is to enable the use of private electromobility in dense urban areas without private parking spaces and to create attractive framework conditions for it. The charging stations to be set up in public spaces, but are available for limited user-groups. An app provides users with authorization to charge at this charging infrastructure with an option to reserve. In addition to an adequate charging infrastructure, the concept will consider the very limited parking options in urban quarters.
Objectives
The aim of the project is to evaluate the “Residential Charging Real Laboratory”. For this purpose, the system for reserving charging stations, the utilization of the infrastructure, the satisfaction of the users with the infrastructure and the effects of the concept on vehicle purchases by the residents of the neighborhood will be examined. Charging convenience and the availability of charging stations will be examined for user satisfaction. The limited group of users in the laboratory is compared and analyzed based on these aspects (including usage acceptance, occupancy, satisfaction) with users of unlimited publicly accessible charging infrastructure. Based on the results, recommendations will be made for the transferability of the knowledge gained.
Approach
A mixed methods approach is planned for the project. Qualitative research methods are conceptually supplemented by quantitative approaches in such a way that the advantages of both types of method are used to the best of their ability. The qualitative work forms the core of the analysis. Two groups are surveyed: the residents who use the charging infrastructure and the residents who do not use the charging infrastructure. In addition, the utilization of the charging infrastructure and the number of vehicles will be analyzed. The results are then discussed in a broad group of experts and recommendations will be formulated.
Project phases
The project phases are divided into the work packages.
