3. V2G Roadmap Subgroup
• Currently, 29 members from 12 different SGIP stakeholder categories
• Include electric utility companies (municipal and IOU), state regulators, electric
transportation industry stakeholders, IT application developers , professional
societies and relevant federal government agencies
• Regular meetings held every two weeks on Mondays between 3-4pm Eastern Time
• Twiki page: http://collaborate.nist.gov/twiki-

4. Subgroup Objectives
• Develop a comprehensive framework for a staged evolution of all key domains within the PEV
industry. Framework will help strategize development and timely adoption of new
technologies, protocols, standards and business practices needed to support the vision of US
PEV industry
• Gather and document all key domain characteristics, capabilities, functionality and
constraints for each stage of the roadmap
• Identify technology gaps to enable planning for research and development of advanced
technology coupled with process innovations
• Facilitate the alignment of standards development for all key areas including charging
infrastructure, vehicle hardware, V2G communication and energy storage. Foster greater
coordination among various stakeholders groups to minimize conflict, duplication, and
divergence in standards development process
• Identify expected roles of market participants along with market impediments for technology
commercialization, business case innovations and protection of consumer interests. This task
will facilitate development of model business practices within the context of regulatory
requirements
• Coordinate and integrate roadmap development with efforts of other V2G subgroups
addressing critical issues such as regulation, cyber security and privacy

5. Factors for widespread EV adoption
• Oil prices
• EV ownership costs
• Policies
• Infrastructure readiness
• Choices available in marketplace(products and services)
• Aftermarkets
• Safety, Security and Privacy

6. PEV Roadmap Framework

Integrated Communications
Sensing and measurement
Advanced components
Advanced control methods
Consumer interfaces and decision support
Data Exchange Needs
Charging Characteristics
Energy Storage
System Impact Mitigation Needs

Standards Development Efforts
Framework developed based on Smart Grid Maturity Model stewarded by the
Software Engineering Institute at Carnegie Mellon University

7. PEV Roadmap – Initial Stage
The goal for this stage is to analyze the first wave of plug-in vehicles, consumer behavior and grid impact
and facilitate the transition to widespread deployment of EV infrastructure.
Stage 1
EV Introduction and Impact Assessment
Technology
Integrated Communications
Sensing and measurement
Advanced components
Advanced control methods
Consumer interfaces and decision support
Data Exchange Needs single data warehouse for EV sales including
battery size and corresponding address;
Charging Characteristics at home and mostly Level 1 and 2; some public
charging at Level 2 and 3
Energy Storage testing as a secondary use for batteries
System Impact Mitigation Needs mainly a concern for “EV Clusters”
Market/Regulatory Issues need simplified permitting and EVSE installation
process; pricing and resale of electricity;
Cyber Security and Privacy
Gaps in
Standards Development efforts

8. Next Stages
Stage 2 - Faster and Smarter charging
Stage 3 - Bi-directional Power Flow and Ancillary Services
Stage 4 - EV as a DER in a fully Integrated, Interoperable and Transactive Grid

9. Collaboration
• Various other SGIP working groups
– Most subgroup members are members in other SGIP working groups
• IEEE
– Roadmap work in IEEE P2030.1 and V2G DEWG to be closely aligned
• ANSI
– Liaison for communication and minimizing duplication of efforts
Roadmap meetings are open for participation from any interested
stakeholder entity

10. Other Key Topics
• International collaboration
• Role of academia (workforce development)
