2014 NEC Change ProposalsPEV Load Diversity Demand Factors Develop demand factors for multiple EVSElocations to account for load diversity.Will require actual data to supportrecommendations. Automated Load Control Add new clause on automated load control formultiple EVSE locations.

2014 NEC Change ProposalsVehicle to Grid Issues Male Plug Blades Energized Review 702 and 705 to see if changes are neededto 625.26. Establish Neutral Add isolation transformer requirement to establishneutral for vehicle to house when islanded fromgrid.

2014 NEC Change ProposalsDC Input to EVSE Add option for EVSE to be powered fromDC source Eliminate extra conversion stage for premiseswith Photovoltaic System / Battery Storage

2014 NEC Change Proposals625.25 Personnel Protection System Add option to allow 1.5 meters betweenPPS and plug PPS would have to be rated for drive overCurrent requirement of 12 inches causes PPS tohang down which can result in damagedreceptacles.

2014 NEC Change Proposals625.29 (D) 4 Supply Circuits Clarify outlet labeling requirements forventilation Shouldn’t be 625.15 (C) “Ventilation Required”

2014 NEC Change ProposalsTables 625.29 (D1) and (D2) Combined Tables 625.29 (D1) and (D2)into a single table with both m3/min andcfm data

2014 NEC Change ProposalsPEV Load Information Add clause on PEV loads in Article 625and reference in Table 220.3OR Add 220.14 (M) on PEV loads Consider adding to PEV loads toexamples in Annex D

2014 NEC Change Proposals625.17 Cable Investigate removing EVSE cablerequirements from 625 as they arecovered in end product standard (UL)

IEC – High Voltage Shore Power EquipmentInternational Electrotechnical Commission (IEC) Technical Committee No.18IEC TC18 MT26 ‐ IEC/ISO/IEEE 60092‐510 Electrical installations in ships ‐Special Features ‐ High Voltage Shore Connection Systems (HVSC‐Systems)Last meeting November 2010 – Berlin, GermanyBrian Sisco to report.2

60092‐510 StatusAfter final editing of the draft CDV by the three (3) joint committeeconvenors in December, document will be forwarded to the IEC for reviewand circulation as a CDV for 5 months. If no negative votes are received thedocument will be circulated as a FDIS for two months followed by apublished standard with a target date of the 3rd or 4th quarter of 2011The combined committee of experts are from: IEC Project Team PT 60092‐510: High Voltage Shore Connection Systems(HVSC Systems) International Organization for Standardization (ISO) TechnicalCommittee ISO/TC 8, Ships and Marine Technology, Subcommittee SC 3,Piping and Machinery, Working group WG11: Cold Ironing IEEE, PCIC Marine Industry Subcommittee, P1713 Electrical Shore‐to‐Ship Connections WG3

International Electrotechnical Commission (IEC) Sub‐Committee SC23HIEC 62613, Plugs, Socket‐Outlets, Ship Connectors And Ship Inlets For High‐Voltage Shore Connection Systems, (HVSC‐Systems)IEC 62613 has been divided into two parts:4

Part 1: General requirements. Contains constructional and testrequirements for both 7.2kV and 12 kV plugs, socket‐outlets(receptacles), connectors and ship inlets. Special requirements weredeveloped to include:– non‐rewireable accessory ‐ accessory so constructed that the cableor wiring cannot be separated from the accessory without making itpermanently useless– field‐rewireable accessory ‐ accessory so constructed that it can berewired by skilled personnel as qualified by the manufacturer– non‐field‐rewireable accessory ‐accessory so constructed that it shallonly be rewired by the manufacturer’s authorized personnel5

Preliminary CDVs were completed in August but are still waiting for finalengineering drawings from the manufacturers before the CDVs can beissued for comment and vote.Pending a positive vote to both the CDV and following FDIS, the Standard isexpected to be published late in 2011.6

National EV Permitting Project UpdateNational RenewableEnergy LaboratoryCarl Rivkin, P.E.Date December 7, 2010NREL is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, operated by the Alliance for Sustainable Energy, LLC.

The EV Charging Station Project Background Started with a request to the Vehicle Technologies program manager from the GridInteraction Technical Team (GITT) GITT requested that the DOE assist in developing streamlined permittingprocedures The request was quite extensive and included data base development to assistjurisdictions as well as outreach to distribute information on EVs and EV charging The permit template portion of the request was funded The permit template is a set of requirements that would likely apply in mostjurisdictions and could be used as the basis for a generic permit Would apply to residential charging installations and would potentially eliminate theneed for an inspection prior to operationNational Renewable Energy LaboratoryInnovation for Our Energy Future

Draft Permit ContentsPermit is divided into 4Sections:1.Jurisdiction info2.Code requirements3.Certification statement4.ChecklistNational Renewable Energy LaboratoryInnovation for Our Energy Future

EV Permitting Project UpdateDraft Permit template complete in FY10Feedback from multiple jurisdictions indicates that they see value in the permit template butare waiting to see the rate of permit applications submitted before taking actionIn October NREL published a Request for Information (RIF) soliciting interested parties to workwith NREL in implementing a streamlined permitting process for EV charging stationsSeveral jurisdictions and organizations responded including the following: Bay Area Air Quality Management District (BAAQMD)Monterrey Bay Electric Vehicle AllianceUtah Department of Environmental QualityMecklenburg, NC Building Code DepartmentBay Area Climate CollaborativeDuke EnergyNREL met with these interested parties and reviewed the permit templateThey expressed an interest in NREL developing information that would put the permittemplate into context by providing information on EV charging and associated safetyissuesNREL will work to develop this information and work these or other jurisdictions can tostreamline their EV charging station permitting processNational Renewable Energy LaboratoryInnovation for Our Energy Future

DatabaseAs project has progressed more interest in potential database component has been expressed by interested parties,such a Boulder County, COData base would coordinate the activities of at least thefollowing entities: Car dealer EV charging station installer Jurisdiction issuing permit for EV charging station Utility supplying charging stationNational Renewable Energy LaboratoryInnovation for Our Energy Future

Contextual InformationSeveral jurisdictions and organizations expressed aninterest in providing information to put the permit templatein contextThis information would include:– Explanations of what a PHEV is and how it is charged– Basic safety information on vehicles and chargingThe DOE AFDC web site contains information that may beusefulNational Renewable Energy LaboratoryInnovation for Our Energy Future

ConclusionThere is interest in using permit templateThere is also interest in producing information that puts thepermit template in a larger contextThere is interest in a coordinating data baseNREL has as their FY11 task implementing the permittemplate or some other change that would streamline theEV charging station permitting process in three jurisdictionsNational Renewable Energy LaboratoryInnovation for Our Energy Future
