Project Description

Main Project

This project will evaluate the commercial benefits of V2G technology at city and district scale learning from technology experience in three case studies in Birmingham, Berlin and Valencia. The project will engage with City Authorities, Grid and Energy Companies, large building owners and EV fleet operators. Objectives of the research are analysis of electric vehicle use profile and energy profile. Another main topic is a regulatory and tariff assessment in these three countries.

Berlin Case: Electrification Potential of Commercial Vehicles Fleets, example Berlin-Moabit

On the streets of Berlin, there are currently around 2,000 EVs in operation and the numbers are increasing rapidly, this now includes carsharing services, company vehicles and buses. The overall trend in Germany is promising: around 98,000 EVs are currently on the streets and 750,000 are expected by 2020. With its growing tech and start-up scene, and the high potential in EV use and infrastructure, Berlin is suitable for a deeper investigation to test a vehicle-to-grid scenario. The research topics in the Bertlin case are:

  • Electrification potential of commercial fleets as example in a urban district area Berlin West Moabit
  • Usage of e-car in commercial fleets
  • Impact on electrical grids
  • Investigation of loading strategies
  • Business model of aggregators of commercial fleets storage capacity

Results of Smart Mobile Energy Project

The results of the project “Smart Mobile Energy” were presented by project leader Dr.-Ing. Wulf-Holger Arndt and project officer Lu Lu in 3-5 May 2017 at the “Berlin Energy Days”.

The result of the project highlights the power regulation system and distribution grid capacity in Germany as the main constrains for V2G solutions. The calculation also shows yearly earning per vehicle seem to be larger in the segment of the passenger car and by offering secondary reserve control power. The sum of the earnings are not profitable for an aggregator to run the proposed business in a successful manner and a fleet operator to motivate him sign a contract with an aggregator. However, it is imagined that the listed costs (for aggregator) can be reduced for example by smart meters that automatically communicate with the aggregator. The aggregator can reduce the fixed part of the costs by contracting larger fleets.
