Motivation and objectives

The successful marketing of e-car sharing still faces a number of unsolved challenges. Thus, high investments for vehicles and for the necessary, appropriate software are to be made. At the same time, substantiated knowledge of customer expectations and market development is still lacking. Further problems arise from the dimensioning and operation of electric vehicles and the necessary infrastructure. This includes e.g. the optimization of vehicle components, the driver assistance systems for short-term use, the installation of appropriate charging infrastructure in the (semi-) public space, ensuring correct loading interface and demand-driven charging strategies as well as handling the range restrictions. Therefore, new (vehicle-) technical solutions are required, adapted to the determining factors of the use of car sharing.

The aim of the project is to overcome existing barriers in the use of e-car sharing by identifying customer-oriented, energy optimized and economically sustainable operation and utilization concepts. Upcoming (vehicle-) technical solutions and business models for the integration of electric vehicles into the operational car sharing business are researched and evaluated. Therefore, an integration of electric vehicles into the QuiCar fleet takes place. E-car sharing is offered at various urban locations of the Schaufenster. The establishment of a university-specific car sharing offer is thereby of great importance. Created as a Living Lab Campus Mobility this allows extensive scientific investigation.

Results from the university research activities in the areas of energy optimized operation and usage concepts are incorporated in teaching and further research of each university. In addition, 50 e-vehicles are to be integrated into the car sharing of Volkswagen AG and used in various urban areas in a first step. Furthermore, additional 150 e- vehicles will be gradually integrated into the collaborative project and will be available for the QuiCar electric fleet.


On order to achieve the defined objectives, the project is structured as follows: An e-car sharing service is provided in cooperation with the cities, public transport providers and universities in the Metropolitan Region. In a first step, the existing QuiCar car sharing fleet with conventionally powered vehicles is expanded to other urban locations of the Schaufenster project in Lower Saxony. In this way, preliminary assessments of user behavior to car sharing services can be realized in the short term. For the second step, involving the setting of an e-car sharing fleet, data on optimal locations and user-specific requirements then already exist. This includes the choice of renting and charging stations, the installation of appropriate charging infrastructure, the adaption of existing booking systems and the acquisition and integration of electric vehicles.

In addition to the offer QuiCar@LUH, starting in summer at the Leibniz University Hannover, further parking positions for QuiCar are installed at different university sites. Those vehicles are equipped with special measuring techniques and used for experimental testing of the developed approaches. Parallel to this, accompanying research on optimized vehicle characteristics and target-compliant operator and use concepts take place in the modules 1 to 3.

Module 1 focuses on expectations, requirements, and the specific usage patterns of (future) users of the e-car sharing and the resulting environmental impacts. Its purpose is the collection, analysis and classification of empirical customer needs and experiences as well as data of car sharing operations. The analysis of environmental impacts and assessments on consequences of the car sharing service are based on this. The knowledge of typical usage patterns of different target groups is an important requirement for the identification of energetically optimal vehicle technology that is explored and tested in the second working module. That module specifically aims at the construction of a vehicle energy model, used for the identification of operation strategies and optimization of components and the complete vehicle as well as the development of vehicle functions designed for the e-car sharing operation. The results from module 1 and 2 are continuously integrated in module 3. They result in the development of operational and business models, which are tested among others in the Living Lab. Besides a short term design and implementation of an initial operating model, multidisciplinary solutions are explored that allow the future development of targeted e-car sharing offers as part of an integrated Life Cycle Service Engineering Toolbox. The developed toolbox is used to replace the initial model through a sustainable business model.

If successful, the project leads to the following results:

  • Creation of a car sharing offer available at short notice
  • Creation of a e-car sharing offer available at short notice
  • Establishment of a comprehensive understanding of the e-car sharing system
  • Providing a toolbox for the development of targeted e-car sharing offers
  • Use the Toolbox to create a sustainable and viable operating business model for e-car sharing
