Technologies, Standards and Business Models for grid-friendly Assetsharing of charging Infrastructure

  • The project FAMOUS is focused on developing technology-based, market-ready solutions for reserving and sharing charging infrastructure and testing them on a pilot basiss.
  • Asset sharing is intended to increase the cost-effectiveness of operationally used charging infrastructure and promote the widespread transition to electrified drive systems.

Problem: The widespread conversion of the transport sector to electric vehicles presents distribution system operators with immense challenges in terms of controlling the grid and, in particular, forecasting the grid load. Charging infrastructure that is installed, but cannot be controlled, and does not provide any information about (future) electricity demand is a highly uncertain factor in the forecast of grid utilisation. Even if the location of the charging infrastructure has been registered with the distribution network operator, the specific charging time and charging demand are not available for such a forecast. However, if the charging infrastructure is linked with the distribution network operator via interfaces and the charging processes are registered in advance (via reservations), this will help the distribution network operator immensely in forecasting future grid utilisation.

Since the development of charging infrastructure in the private sector is also increasingly occurring in an uncoordinated manner and many individual charging points are being created at different grid transfer points, the distribution network operator is forced to take various buffers into account during grid control and grid expansion. Depending on the application, charging at private charging stations will have some time windows of charging and also no charging. However, a uniform demand would be advantageous for the distribution network operator. To achieve this, it would be necessary to make its own charging infrastructure available to other users. In this way, fewer charging points would have to be installed overall, which would lead to fewer buffers in grid operation. Charging at these charging points would also take place more evenly throughout the day. This would increase the probability of being able to realise charging processes reliably, cost-effectively and in a particularly secure manner at all times.

Objectives of the project FAMOUS

  1. Development of an asset sharing market module for reserving and sharing private charging infrastructure in order to increase its cost effectiveness and availability.
  2. Linking the booking system for charging processes with the grid status estimate of the distribution network operator to ensure grid stability and security of supply.


To successfully solve the problem and achieve the objectives, users must be involved in the asset sharing design process – from conception to planning to implementation. Their assessment of when asset sharing and the reservation option is considered useful can be recorded. In addition, users' assessments of bidirectional charging options can be collected. In addition, the tracking of vehicles via the DLR MovingLab tool in combination with the analysis in the DLR CURRENT tool makes it possible to estimate charging requirements over time. The final combination of the results charging requirements and the comparison with the results provided on network utilisation can thus be used to generate further development potential for shared concepts.
