摘要

In the public discussion the development of charging infrastructure is one of the most important requirement for the market penetration of electric cars. Different initiatives and approaches are in preparation and the German government has announced a funding program for public charging infrastructure with a budget of 300 Mio. Euro. In the last 4 years in many projects and research initiatives gained a lot of experience with construction, operation, function, reliability and roaming of charging infrastructure. However in discussion with experts and drivers of electric cars it was obvious, that the current charging infrastructure is principally working, but there is still a lot potential for improvements. To identify the most important action fields a big study in Gennany among experienced electric car drivers and emobility interested people in 2016 was conducted with the question, how the user oriented charging infrastructure looks like from a customer point of view. This survey is part of the government founded "parallel research into effectivity within the German federal program "Electric mobility Showcase". In this paper the results of the survey will presented. In the survey there were following categories investigated: Usage of charging infrastructure, locations, Access, Payment, costs and tariff modelling. The result clearly showed that the current infrastructure overall was rated quite bad by the users and there is a big need of action in many issues. This survey is the most detailed survey concerning the user perspective of charging infrastructure and gives the relevant stakeholder a lot of information, how to improve the charging experience in future. The results of this survey is were published in March 2017 and the study is only available in German language. So the EVS 30 is be the first event, where the results will be available in English Language.
