The research project "Bidirectional Charging Management" aims to develop and test a holistic, user-oriented offer for the integration of bidirectional electric vehicles into the energy system. The intelligent interaction between electric vehicles, charging infrastructure and energy system ensures an improvement in grid stability and security of supply, while also maximizing the use of renewable energy. The project will identify, evaluate and demonstrate various bidirectional charging applications. After the development phase, a comprehensive pilot operation will be launched in 2021 encompassing 50 bidirectional BMW i3s to demonstrate the customer benefits and value of the technology.

The FfE in BCM

Within the BCM project, the FfE’s focus is on the following research areas:

  • Use cases for bidirectional electric vehicles
  • Simulation of grid loads in the distribution grid using GridSim
  • Simulation oft the energy system using ISAaR
  • Measurement concept and data evaluation of the field tests
  • Integration of additional partners through the FfE joint project

In addition to FfE e.V. and FfE GmbH (FfE), the BCM partners include the BMW Group (consortium leader), KOSTAL Industrie Elektrik GmbH, TenneT TSO GmbH, Bayernwerk Netz GmbH, Karlsruher Institut für Technologie (KIT), Keo GmbH and the University of Passau.

The project structure

The research project is divided into seven subprojects (TP), which are illustrated in the following figure.

The FfE is leading subproject 3. The scope of this subproject includes a detailed study of the technical and regulatory framework for bidirectional charging, identification of various use cases, and the subsequent derivation and evaluation of promising business models. Also,  various simulations will be conducted both by the KIT and FfE to evaluate the grid and system reactions. The examination of regulatory issues will be led by Schweizer Legal. Finally, action recommendations will be derived on the basis of the results.

The FfE joint project

The FfE contributes a special component through the "FfE joint project", which involves a large number of stakeholders from the energy sector and industry. By including these stakeholders, a widespread exchange of experience is facilitated. As a result, standardisation work is accelerated and the solutions developed will be more widely accepted.

Funding and project partners

The research project is funded by the Federal Ministry of Economics and Energy (BMWi) (funding code: 01MV18004F).

The following joint project partners support the FfE’s research financially, as well as with data or individual, practical experience.

About the Bidirectional Charging Management Research Project – BCM:

The innovation project "Bidirectional Charging Management - BCM" pursues the objective to develop and test a holistic, user-oriented offer for the integration of electric vehicles into the German energy system.

Bidirectional electric vehicles are charged with renewable energy from the electricity grid while simultaneously offering stabilizing services to the grid.

Therefore, in addition to appropriate user-friendly technological solutions, this requires intelligent interaction between vehicles, charging infrastructure and power grids. The interdisciplinary project partners from the automotive industry, the energy industry, and scientific community are developing holistic solutions for this purpose.

Besides the consortium leader BMW Group, the partners KOSTAL Industrie Elektrik GmbH, TenneT TSO GmbH, Bayernwerk Netz GmbH, Forschungsstelle für Energiewirtschaft e.V. (FfE), Forschungsgesellschaft für Energiewirtschaft mbH, Karlsruhe Institute of Technology (KIT), KEO GmbH and the University of Passau are also involved.

The innovation project is funded by the Federal Ministry of Economics and Energy. The Deutsche Zentrum für Luft-und Raumfahrt (DLR) is responsible for the the three-year pilot project’s project management.
