Mission Statement Review Participants suggested making reference to meeting customer needs in the mission statement. The revised version shown below will be discussed by the ISC. Final Revised Mission Statement Transportation Electrification Committee Support the development of infrastructure to facilitate global electric grid connectivity of transportation systems by: • Assessing infrastructure requirements to minimize the negative impacts on utility and customer systems • Facilitating and actively participating in appropriate codes and standards committees to promote connection standardization, safety, efficiency and functionality of grid-connected transportation systems • Supporting the implementation of electric transportation systems that benefit the consumers and reduce carbon footprint and dependency on oil in accordance with applicable laws and regulations. ISO TC8/IEC TC 18/IEEE P1713 Update/ IEC Additional Information Charging Systems Greg Nieminski, EPRI Consultant, gave an update on the IEC standards work (see Attachments). Mr. Nieminski began by summarizing the process for standards development under the IEC. With regards to IEC TC18 MT26 (electrical installation in ships), the committee received an additional 350 comments from the national committees. MT26 committee will meet in Seattle on June 12-16 to resolve the comments and prepare a committee draft for voting. With regards to IEC SC23H PT HVSC (IEC 62613 series on high voltage plugs, connectors and inlets), committee drafts were issued and comments are expected in June for discussion in Seattle on June 16-17. With regards to IEC TC69 WG4 (IEC 61851 series on EV conductive charging system), the IEC has been working on different documents. Part 1 (general requirements) has been completed and is awaiting publication. Parts 21 and 22 have been circulated to experts for review. For Part 23 (DC charging), a new work proposal has been accepted and a new project team will meet to develop a working draft in July. Regarding Part 24 (control communication 2 protocol), a new work proposal has been sent out with requests for support from national committees. With regards to IEC SC23H PT 62196, both Parts 1 and Part 2 have been modified based on comments received and another committee draft will be issued. Several issues have been raised and a survey has been sent out to all national committees. The issues are: • The need for shuttered socket-outlets in some countries. • The need for IEC 60529 degree of protection IPXXD or equivalent protection against electric shock for a vehicle inlet intended for bi-directional energy flow if the connector is withdrawn. • Other additional protection for the EV cord set used for bi-directional energy flow if the plug is pulled out before the connector. For new 62196 Part 3 (DC Coupler), a new work proposal was issued in March with requests for support from national committees. Results should be known by the end of June. Discussion focused on reverse power flow in bi-directional energy. With regards to cord sets, bi-directional flow could be prohibited. For hardwired EVSE’s, there has to be communication. This issue may have already been addressed by manufacturers of portable power supplies. While not an immediate concern, the issue needs to be addressed now to avoid the problem of retrofitting equipment later. The Code Task Force should look into this issue for the next code cycle. The group expressed interest in getting an update on IEEE of 1547. Participants also discussed obstacles to V2G including the possible need for real time information and high band width for ancillary services. Mr. Nieminski requested input for IEC 23H and TC69. The following agreed to provide advice and feedback to Greg Nieminski and the US Technical Advisory Group on IEC 23H and TC69: Sam Girimonte, Manoj Karwa, Gery Kissel, Arindam Maitra, Efrain Ornelas, and Greg Robinson. ACTION ITEMS: Arindam Maitra and Manoj Karwa will contact mobile appliance manufacturers, especially portable power generators, to find out how they deal with safety issues regarding reverse power flow. Frank Lambert will provide an update on IEEE 1547 at the next meeting. TSE Updates Dan Shanahan, CabAire, reported that they recently opened a facility with truck stop electrification in North Carolina and added 28 electrified parking spaces along the Pennsylvania Turnpike. New facilities will open at the Delaware Welcome Center in June and along the New Jersey Turnpike in the Fall. PQ Spectrum Analysis of On-Bard Chargers/Distribution Impact Update Arindam Maitra, EPRI, gave a presentation on on-board charger characteristics and an update on the impact of plug-in vehicles on the grid (see Attachments). EPRI collected data from 10 different EV chargers and 69 different 230V AC power supplies. The 3rd harmonic was 3 below 13% distortion for all except one charger. In general, total harmonic distortion was less than 15% except for one charger. The next steps include multiple charger evaluation under different scenarios and assessment of the off-board DC charger. During discussion, Mr. Maitra pointed out that the problem is how the different harmonics add up with multiple chargers. With regards to grid impact Mr. Maitra described the characteristics of two feeders at two different PEV penetration levels and analyzed asset capacity, transformer overload factors, and voltage profiles. They also looked at aggregate power demand from uncontrolled charging. The analysis shows that smart charging helps if done correctly and that distribution load management is critical. There is adequate supply to meet PEV energy needs, but the impacts of PEV clustering are likely and transformer load monitoring and load planning based on detailed distribution models are important. Discussions revolved around PQ issues when the PEV is not charging, as well as measuring the load during charging versus the load during battery pre-conditioning and cabin conditioning in order to determine actual energy efficiency ratios. Utility Challenges and Obstacles/Discussion: Future direction, priorities, next steps, and schedule Mark Duval, EPRI, pointed out that TEC and PHEV committees are coordinating their agendas such that it would be important for participants to attend both meetings. Barbara Gonzales, Pepco, presented the following utility challenges: the need to share information on different pilot projects, the impact of PJM Interconnection issues related to

    V2G Injector: Whispering to cars and charging units through the Power-Line Sébastien Dudek, Jean-Christophe Delaunay and Vincent Fargues [email protected] [email protected] [email protected] Synacktiv Abstract. Since vehicles became connected to a bus called CAN (Con- troller Area Network), many “garage” hackers got interested in investi- gating the different controllers, known as ECUs (Engine Control Units), and accessible via the On-Board Diagnostics (OBD) port. Among those different controllers, some of them are accessible via Wi-Fi, others via GPRS, 3G and 4G mobile networks, that could be attacked during a radio interception attack [19]. Moreover, another little-known vector of attack will appear with the deployment of V2G (Vehicle-to-Grid) systems that communicate via power lines support. Nevertheless, no public tool exists to interface with these systems, but also to analyse and to inject V2G traffic. That is why we have developed a tool called V2G Injector to attack these systems. In this article, we will briefly introduce the V2G concept and its similari- ties with domestic Power-Line Communication systems. Then, we will present the techniques we use in our tool that aim to interface with the system, monitor and inject traffic. We will also present a new specification vulnerability in the communication medium we have been able to exploit to intrude the V2G network. To finish, we will talk about issues we have found during our tests on real equipment, and mitigations we can encounter, or apply, in some contexts as well as possible bypasses. 1 Introduction: rise of V2G Due to its environmental friendliness, Electric Vehicle (EV) is gaining popularity in U.S.A, Japan, China and some countries in Europe.

  • Evaluation of OCPP and IEC 61850 for Smart Charging Electric Vehicles
    World Electric Vehicle Journal Vol. 6 - ISSN 2032-6653 - © 2013 WEVA Page Page 0863 EVS27 Barcelona, Spain, November 17 - 20, 2013 Evaluation of OCPP and IEC 61850 for Smart Charging Electric Vehicles Jens Schmutzler1, Claus Amtrup Andersen2, Christian Wietfeld1 1Dortmund University of Technology, Communication Networks Institute, Dortmund, Germany, EMails: [email protected], [email protected] 2EURISCO Research & Development, Odense, Denmark, EMails: [email protected] Abstract Interoperability of charging infrastructures is a key success factor for E-Mobility. Standards like ISO/IEC 15118 and IEC 61851-1 are developed to ensure base level interoperability of front-end com- munication and signaling processes for smart charging between electric vehicles and charge spots. With the Open Charge Point Protocol (OCPP) a forum of European industry members also moves towards a common back-end protocol for charge spots intending to reduce and secure overall investment costs. However, in the current form OCPP lacks means for enabling grid services based on smart charging. In this paper the authors provide a review of today’s state of the art in ISO/IEC standardization of the V2G Interface and furthermore detail how OCPP could leverage existing standardization efforts for grid automation from IEC 61850 in order to overcome its shortcomings. Keywords: Smart Charging, OCPP, IEC 61850, ISO/IEC 15118, Vehicle-to-Grid Communication Interface, V2G 1 Introduction beneficial to standardize back-end integration as- pects of charging infrastructures in the long term.
