Programme of Work

Task 28 "Home Grids and V2X Technologies" will explore the technologies and accompanying issues associated with the use of electric storage from plug-in electric vehicles (PEVs) for uses other than powering the vehicles. Customers may use their PEV electric storage capabilities for other applications such as vehicle-to-grid (V2G), vehicle-to-home (V2H), vehicle-to-load (V2L), and vehicle-to-vehicle (V2V). The characteristics of these applications include the following:

  • V2G: Electric utility may be willing to purchase energy from customer during periods of peak demand, and/or use the EV battery capacity for providing ancillary services.
  • V2H: Use of the PEV as a home generator during periods of electrical service outage and for increasing self-generated renewable energy usage.
  • V2L: Use of the PEV storage to provide power to a remote site or load that does not otherwise have electrical service. Examples include construction sites or camp sites.
  • V2V: Use of the PEV storage to transfer electrical energy to other PEVs in case of emergency.

Collectively, these four applications are known as Vehicle to Everything (V2X), a term that now represents the strategic technology for ensuring sustainable, secure, and cost-effective deployment of electromobility.

There remain technological and economic "knowledge gaps" in realizing the full potential of V2X technology. Task 28 is going to address these gaps by means of creating an international network of experts who will conduct bi-annual meetings on different strategic topics.

Special attention will be put on the V2H concept as one of the most promising applications of V2X technology. V2H technology has a high potential for energy cost reduction by means of enabling energy arbitrage and increasing on-site renewable energy generation capacity while improving security and quality of supply.

Working Method

The overarching objective of Task 28 is to investigate the means for facing the technical, economic, and policy challenges of V2X technology. The whole V2X value chain will be considered in this process including power system operators, power electronics industry stakeholders, and the most relevant original equipment manufacturers (OEMs).

Utilizing the existing IA-HEV framework, Task 28 will provide the opportunity to bring together the key actors in the EV industry including research and industry players and energy policymakers in order to discuss the requirements for the development and the use of V2X technology.

By leveraging the technical skills and different experiences of the participants, it will be possible to improve the currently available market analyses of V2X technology. In particular, the following specific objectives will be pursued:

  • Analyzing the technical and economic viability of V2X technology including questions such as:
    • When V2X will be viable as a consumer application? What are the potential synergies with home energy self-produced electricity?
    • What is the value provided by V2X in terms of security of supply? What would be the impact on tax revenues?
    • What will be the role of the different stakeholders (mainly the utilities)? What will be the impact of aggregation?
    • What is the effect of the different national regulatory frameworks?
  • Developing a policy making toolbox and a technology roadmap for those decision-makers who introduce V2X technology in their countries.
  • Creation of an international technical information exchange platform for enabling knowledge-sharing among scientific institutions and industrial representatives working on V2X issues.
  • Promotion of new V2X technology demonstration projects.

The goal of Task 28 in the coming years is to use the expected results both for policy-makers and industrial partners to promote V2X technology worldwide. Furthermore, the gained knowledge and results of such investigations can be integrated to the market research and business modeling carried out by the different actors in the worldwide EV market.

Duration

Task 28 is presently planned to run for two years from Summer/Fall 2014 through Summer/Fall 2016.

Member Countries

The current member countries are Denmark, Spain, Switzerland and the United States. Each joined in May 2014. Other countries have expressed an interest in joining.

Financing

Any IA-HEV member may join. There is an annual contribution for membership. In addition, as in any IEA Task, attendees at the meetings are kindly asked to cover their own costs linked to participation (i.e., salaries, travel expenditures, accommodations, etc.). In addition to attending meetings, participating members are expected to set aside an appropriate amount of time and resources to support directed activities (i.e., research) that may be required. Please contact the Task 28 Operating Agent for more information.

Benefits of Participation

Among the expected benefits of participation, the organizations participating in Task 28 will broaden and deepen their own expertise in the field of V2X technology by means of strengthened working relationships and international collaborations.

Task 28 participants will have the opportunity to participate in five expert workshops, during which the following specific topics will be addressed:

  • WS1: User requirements, business models, and regulatory framework
    • Categorization of V2X applications in a common basis;
    • Definition and analysis of V2X business models; and
    • Regulatory framework analysis.
  • WS2: Power System
    • V2X integration into power and energy markets;
    • Communication protocols and standards; and
    • Interfaces design and interoperability.
  • WS3: Bidirectional chargers
    • Control, metering, and connectivity standards;
    • Power electronics topologies and cost comparison; and
    • Energy efficiency and security.
  • WS4: V2X EVs
    • Effects of usage profiles on battery lifespan;
    • Improved models of battery degradation for V2X;
    • Market potential as a function of mobility patterns; and
    • Standards that may facilitate (or hinder) interoperability with V2X for EVs.
  • WS5: Conclusions and policy recommendations
    • V2X regulatory framework;
    • Technology roadmap: V2X technology state of the art and innovation requirements; and
    • Market research.

Task 28 participants will receive a summary report including a set of recommendations for policy makers together with the presentations of the speakers.
