Plug Into The Smart EU Grid

The of the case study Green e-Motion is to accelerate growth in the European market for electrically chargeable vehicles through the realization of complete infrastructure that delivers a seamless, integrated experience for end users.  

Green eMotion is using this combined know-how with 42 partners, to develop the following:

  1. Improvement in standardization for electromobility: highlighting the most urgent “new” needs and tackling them
  2. Development of a marketplace as common innovative service platform: Europe-wide roaming and other services connecting the electromobility market players
  3. Comprehensive studies on grid impact by EVs (harmonics, low voltage grid, reinforcement costs)
  4. Extensive amount of valuable electromobility data: use patterns, environmental impact (e.g. CO2)
  5. Evaluate appropriate business models for electromobility
  6. Analysis of the operability of electric vehicles under real-life conditions and development of policy guidelines as a basis for implementation in the mass market.
  7. Policies and Regulations for different levels in the administrative and political area.

Results

  • Green eMotion recommends selected standards for an inter-operable electro mobilty system (de facto standards for Europe)
    Green eMotion partners defined the following information to be included in the communication protocol:

    • Management of EVSE, including controlling, monitoring, the maintenance, provisioning, firmware update, and configuration (profiles) of EVSE and associated backend system
    • Authentication/authorization/payment of charging sessions, incl. roaming, pricing and metering information
    • Management of charge session, incl. interface for HMI, reporting
    • Information exchange, e.g. required energy, grid usage, contractual data, metering data
    • Associated added-value services
    • The different requirements for security, privacy and other safety associated issues should be integrated into the specifications
  • Green eMotion defines the IT architecture for a European market place including interfaces which allows competition in implementation
    • The Electric Mobility Infrastructure Open protocol shall focus on the management of chargers following IEC 61851. This management shall include AC and DC charging, as well as different profiles for simple AC chargers, AC with ISO 15118, DC Combo, DC CHAdeMO, and inductive chargers
  • Green eMotion adjusts the proposals and results in discussion with a broad stakeholder base

Objectives

  • Green eMotion recommends ways to an optimised grid and charging infrastructure
  • Green eMotion tests and demonstrates the interoperability of an electromobility system in selected demo regions
  • Green eMotion analyses the operability of electric cars under real life conditions und develops recommendations for the implementation of the mass market (to increase user acceptance)

Why they acted?

Driver wants to use an e-car everywhere in a convenient way:

  • Compatible plug/interfaces, identification, authorisation, billing
  • Find and reserve charging posts, eco-routing, cost-value ratio

How we did it?

  • In the Green eMotion EU demo regions, 70.000 EVs and more than 80.000 charging posts have been installed (2015)
  • Standards: Study which standards are in use and gap analysis
    Standardisation needs to get electromobility on track
    Michele de Nigris (RSE)
  • Vision, strategy and policy of the Green eMotion municipalities – what’s necessary to roll out electromobility
    Amit Yudan (Betterplace)
  • What’s necessary as charging infrastructure and how to integrate it into the grid
    Fainan Hassan (Alstom), Thomas Wiedemann (RWE)
  • Business Analysis for ICT solutions including business scenarios; ICT reference architecture for a market place system and ICT service use cases; first insights on protocol specifications for ICT solutions
    Gerhard Baum (IBM)
  • 140 companies and institutions have applied for cooperation with Green eMotion

Next step

Next step is handing in the NWIP via one national standardization body by a partner

Lessons Learned

  • More time needed to be given to the organization of the forum as the formulation of the agenda between three projects takes longer.
  • The feedback from delegates made it clear that they would like to see more information on each session in the published agenda.
  • The agenda needs to be published further in advance of the meetings in order to allow potential attendees to fully evaluate whether they would like to attend or not.
  • Feedback has suggested that there should be more time in the workshops for discussion and less presentation time. The next forum meeting will have longer workshops and rules for moderators to ensure that time is kept to allow for proper discussion and interaction in the workshops.
  • LinkedIn is a valuable tool to spread and share news and discussion about the projects. It allows for quick and direct interaction with stakeholders.
  • With more promotion the use of a Twitter hashtag may be helpful to increase interaction at events.
  • Continuing to use a variety of other projects and external stakeholders in the agenda helps to give a better overall picture of electromobility at present and create an awareness of other projects and regions.
