Transatlantic Workshop on Electric vehicles and Grid Connectivity November 17 th, 2010 Brussels, Belgium Eric Simmon

EV Charging Major Concerns Charging points available when/where needed Charger standardization V2g communication standardization Impact of charging load on grid Peak load increase Localized effects

V2G Interaction Support for flexible charging scenarios (Roaming) Charging on PEV rate plan at home, at work, at neighbors (within utility network) Charging on plan on other utility networks Using credit card or pay as you go on local or roaming networks Privacy Support for DR (Demand Response) PEV charge control for load balancing PEV as short term energy source for event response

V2G Standardization Information model Abstract common model can be used to develop implementation specific models Communications system Multiple communication systems to provide flexibility Connector and socket AC, DC Charging system

SGIP Vehicle 2 Grid (V2G) Strategic V2G Domain Expert Working Group (DEWG) Analyzing regulatory barriers, other related standards Roaming requirements V2G specific security and privacy issues Any other strategic issue Tactical PAP-11 – Common Object Models PAP-XX – Implementation specific V2G

Why Global Harmonization? Lower cost of equipment Less overhead for manufacturers Lower cost for consumers Easier system integration Improved vehicle choices Higher reliability Less testing Less complexity
