Background and potential

Background and potential of Shared E-Fleet

Environmentally sound and energy-efficient mobility concepts will change life in our society. According to the German federal government’s “Electric Mobility Programme” electric vehicles play an integral role in sustainable energy and transport policy. By using various renewable energy sources for charging, electric vehicles make carbon-neutral mobility possible. Furthermore they can help balance and stabilize energy grids. In addition, the development of innovative products and services in the field of electric vehicles also creates a favourable environment for Germany as a business location.


Regarding the user acceptance of electric vehicles, corporate fleets in particular can be seen as a very important market segment which can also provide a positive signalling effect towards the general public. At the moment about 100,000 companies in Germany own a corporate fleet, a large part of them being small and medium-sized enterprises. These corporate fleets consist of a total of approx. 10 million vehicles, divided into approx. 4.5 million passenger cars and approx. 5.5 million trucks. Additionally there are another estimated 5 million corporate vehicles which are not approved for use on public roads. The large part of corporate vehicles (approx. 48%) can be found in fleets with less than 100 vehicles. Thus, there is a great market potential for electric vehicles in this sector.

The reasonableness and cost-efficiency of electric vehicles in corporate fleets rise with:

  • a higher utilization rate of the electric vehicles,
  • a better alignment of vehicle operation schedules and charging strategies,
  • a better exploitation of the potentials of smart grids and renewable energies,
  • a simplification of usage and billing and
  • a better integration of the electric vehicles into an intelligent traffic system.

For a lot of SME, and at certain locations of large companies, electric vehicle fleets are economically reasonable only if the fleet is shared by several companies, especially in technology parks, industrial areas etc.

A study conducted in advance by the Fraunhofer IAO (in collaboration with the project partners baimos technologies and TWT Science & Innovation) in the three technology parks STEP (Stuttgarter Engineering Park), MTZ (Münchner Technologiezentrum) and gate (Garchinger Technologie- und Gründerzentrum) with 30 participating companies revealed potentials for a fleet-sharing model. The companies estimated the periods of inactivity of their companies cars at over 60% and frequently even at over 80% (low level of utilization); the cars rarely or never need to have special equipment for business trips (shared use is possible), and the distance travelled on business trips is often less than 50 km (suitable for electric vehicles). Hence the use of electric vehicles which are shared by different companies in order to increase utilization is very reasonable and beneficial.

In order to realize such a shared use of electric vehicle fleets (“Shared E-Fleet”), suitable ICT solutions deploying new methods and processes are necessary. They have to be developed and tested based on real use cases. It is also important that the developed solutions can be applied on a wide range of electric vehicle fleets.

The project Shared E-Fleet realizes this intention of a shared use of electric vehicle fleets. The infrastructure of intelligent traffic and energy systems will be integrated seamlessly in the process.
