Grid integration of mobile energy storage: test based evaluation, technical potential and willingness to pay of car owners (NET-INES)

Project aim

The aim of the project is to work out the integrated technical, economic and motivational conditions for the grid integration of mobile electrical energy storage - consisting of traction batteries of electric vehicles (EV) - and their use for network services (vehicle-to-grid (V2G)). The conditions of battery, grid and the expectations of potential electric vehicles owners are particularly considered. Thus, the analysis of the project NET ELAN (http://www.fz-juelich.de/iek/iek-ste/DE/NET-ELAN/_node.html) is focused and deepened.

Central questions

The analysis is guided by three central questions:

  1. What additional aging of the traction batteries can be expected if storage capacity of electric vehicles is used for network services?
  2. Which conditions should be met for car owners to agree to a parallel use of the car battery?
  3. How much can bundled storages of electric vehicles contribute to the stability of the grid and the integration of fluctuating renewable energy sources?


By answering these questions, the understanding of technical, economic and motivational conditions of the network integration is extended. This is a prerequisite for the development of applications for the grid integration of mobile energy storage.

Methods

To answer these central questions:

  1. tests for the evaluation of the battery aging,
  2. tests for the analysis of network applications,
  3. polls for the identification of motivational conditions of car owners for the network integration of their mobile storages will be carried out and
  4. economic conditions and incentive systems for car owners will be analyzed..
