Review and Approval of Past Minutes and Action Items The group approved the minutes (#10-01) of the previous meeting (March 3, 2010) in Orlando, FL. The status of action items from the previous meeting is shown below. Action Items: March 3, 2010 (Orlando) Meeting # ACTION ITEM STATUS 1 Mark Duvall will invite Navistar to the next meeting. Delete action item 1 2 Gery Kissel will invite Charlie Groeller to discuss truck Ongoing (See note below) connectors at the next meeting. 3 Efrain Ornelas will share with the IWC a spreadsheet Included with the minutes outlining relevant codes and standards as well as EPRI’s response to a CPUC report. 4 Arindam Maitra and will get feedback from AeroVironment and Ongoing Ed Wagner utilities on whether isolation transformers are required for fast chargers and report at the next meeting NOTE #2: Retain action item but find out if Mr. Groeller has been replaced. 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
