Revised PHEV Mission Statement Plug-In Hybrid and Electric Vehicle (PHEV) Working Group

Support the development and deployment of plug-in hybrid and electric vehicles (PHEVs) by: • Facilitating and actively participating in appropriate codes and standards committees on PHEVs to promote the safety and function of plug-in hybrid and electric vehicles • Facilitating the interoperability of public charging infrastructure for PHEVs • Identifying infrastructure and utility issues for PHEVs as mobile distributed electric resources (V2G).

ACTION ITEM: Barbara Gonzalez will send her suggestions on the mission statement to Jorge Emmanuel. [completed]

NEC 625 – 2011 Changes for PHEVs Gery Kissel, GM, reminded the attendees that Mike Hittel, GM, now represents the IWC in Code Panel 12. Mr. Kissel reviewed the 15 proposals supported by the IWC. The proposals to include electric motorcycles and to revise the definition of Rechargeable Energy Storage

2 System were accepted. The Code Panel accepted in principle a definition for Plug-in Hybrid Electric Vehicles. There were no changes to 625.13 and the Code Panel clarified that EVSE meeting the requirements of 625.18, 625.19 and 625.29 can be cord-and-plug connected even when the voltage is greater than 120 VAC. With regards to 625.29(B), the panel explained that the 18” lower height limit was based on the upper gasoline fume height limit and not related to the ADA. The Code Panel rejected other proposals of concern to the NEC Code Task Force.

Oregon Statewide Alternate Method No. OESC 09-01 Dennis Clements, Oregon Building Codes Division, explained the state of Oregon is using alternative regulatory options to install public charging (see presentation in the Attachment). In the regulations, Level 2 EVSE units must be listed by a national testing laboratory or an Oregon-approved evaluation firm. The state collected data from industrial and warehouse charging operations and adopted a demand factor table based on NEC Article 555. Mr. Clements gave examples of service calculations that showed reductions in the load scenario using demand factors. During discussion, Mr. Clements explained that cost is the main driver for developing diversity factor tables.

EV Charging System in a Large Parking Deck Mesut Baran, North Carolina State University, gave a presentation on their EV charging system for a large parking deck (see Attachments). They developed a supply circuit design for a parking deck with 500 spots and 3.8MW capacity for level 2 charging. In their study, a constant-current, constant-voltage charging scheme was considered with charge profiles depending on the initial state of charge. One EVSE rated at 120/240V served two parking spaces and a single feeder cable supplied 1 to 7 EVSEs. Using statistical analysis, they concluded that the effects of diversity on cable sizing are negligible for small numbers of EVSEs, but due to diversity, the transformer can be sized for 60% of the maximum load. They also analyzed the effect of current harmonics and harmonic cancellation, concluding that there is little change in the derating factor for the distribution transformer. During discussion, Jose Salazar, SCE, stated that they had done a similar analysis and also came up with a 60% derating. Arindam Maitra, EPRI, noted that some chargers use a constant power scheme. Efrain Ornelas, PG&E, suggested that some of the state of charge profiles may be old and would depend on regional variations and EV range, among others.

NEC 625 – 2014 Changes for PHEVs Greg Nieminski, EPRI Consultant, reported that the revisions to Article 625 are currently being processed by the NEC. Plans for revisions under the next cycle are on hold until the final changes can be evaluated. For the 2014 code cycle, diversity factors would be the most important. The Code Revision Task Force needs data to propose diversity factors by the proposal deadline of November 2011. There may be other minor revisions that could be proposed. Participants should contact Greg Nieminski or Gery Kissel with their suggestions.

ACTION ITEM: All with data on charging times, charging profiles, and other information useful for developing diversity factors should provide the data to Greg Nieminski.

3 SAE J1772 Connectors Update Gery Kissel, GM, gave a status update on SAE J1772TM, the DC fast charge system, the eTec DOE project, and the SAE timeline (see Attachment). J1772 TM was published on January 15, 2010. Coupler compatibility testing will be conducted by manufacturers by exchanging samples among themselves and the results will be presented to the SAE Taskforce. EPRI has started a project on EVSE compatibility testing and interested manufacturers are encouraged to contact John Halliwell, EPRI. SAE has begun discussion on a DC fast charging standard with coupler interfaces based off of the AC charging standard. JARI/TEPCO have developed their own fast charge system. To support the Leaf, the eTec DOE project will use 260 JARI/TEPCO chargers which may become a de facto standard. Mr. Kissel expects a finalized standard by mid-2011. During discussion, Mr. Kissel explained that the use of the SAE logo does not mean that a coupler has been tested by SAE.

SAE J1772 – DC Charging Gery Kissel, GM, gave a brief presentation on the 240V plug and cord EVSE (see Attachment). He described three common charge configurations: EV public charging, EV home charging with the charge point fixed to a wall, and an EV charge cord with an inline control box. He also explained NEC 625.18 (interlock requirements), 625.19 (automatic de- energization of cable upon exposure to strain) and 625.29 (indoor site requirements). Designs for 240V portable cord-and-plug EVSEs that meet the NEC requirements have not yet been identified. The 240V EVSEs must comply with 625.18 and 625.19. A portable cord-and-plug is possible as long as it meets the NEC requirements.

International Standards / J1772TM Harmonization Greg Nieminski, EPRI consultant, gave a progress report on the IEC standards committees. A major update of IEC TC69 WG4 Part 1 was completed and is being released as a Final Draft International Standard. Work started in February 2010 on Part 21, which contains EV constructional and test requirements for conductive connection to an AC or DC supply, and on Part 22, which relates to AC charging stations. A New Work Proposal for Part 23 (DC EV charging stations) was sent out on January 2010. Finally, on IEC SC23H PT 62196, both Parts 1 and 2 were completed in February 2010 and sent to the IEC office to be release as a Committee Draft. Mr. Nieminski emphasized that a US position should be submitted to the US TAG committee.

SAE J2836 / J2847 Communications Update Rich Scholer, Ford, gave a summary of developments related to fast charging (see Attachment). He reviewed the DC fast charging system and described the output of his interactive excel tool that allows the user to evaluate different options. Noting that a 1C rate is the charge in 1 hour from 0% to 100% based on total capacity, that PHEVs start at 0% SOC and BEVs start at about 20% SOC, he explained how the tool could be used to evaluate 30-minute and 10-minute fast charge for PHEVs, BEVs and high-end BEVs to see what fast DC power can offer. His analysis suggests the same Level 1/level 2 connector for 150A standard DC charging which could also work for 3 phase. A 360A connector for DC rapid charging could be a second vehicle connector. He compared connector sizes for standard, fast, and rapid charge and suggested a 2” diameter combination connector. He also compared the time savings between 80kW and 50kW, adding that 80kW is 60% oversized for a 150A

4 requirement. He then summarized EVSE charging scenarios using the standard combination and rapid charge connectors. During discussion, Mr. Scholer noted that his goal in the analysis is to reduce the total package. Various participants discussed the potential impact of fast charging on batteries and new battery technologies.

Test Track Mike Romeo, GM, took the participants to experience the high-speed vehicle simulation ride at the GM test track in the Epcot theme park.

IEEE P2030 / Vehicle to Grid Rich Scholer, Ford, gave a presentation on initial and current SAE documents, status of IEEE P2030, the schedule and status of SAE and ISO/IEC communication work, charge rates, connector options, and next steps (see Attachment). SAE J2836 is an information report on the communication requirements between plug-in electric vehicles and the grid based on use cases. J2847 is a recommended practice that defines the detailed messages and specifications for vehicle utility communications. Mr. Scholer described the partitioning, plans and next steps for J2836 and J2847. The new J2931 is a recommended practice related to communication using power line carrier. IEEE P2030 is a draft guide for grid interoperability and deals with energy sources, security, and communications technology. He described the NIST conceptual diagram and the status of the work of NIST and the UtilityAMI OpenHAN Task Force. Under the SAE schedule, communication stack development will be completed 2010 with field testing in 2011. Parts 1, 2 & 3 of ISO/IEC 15118 match SAE J2836, J2847, and J2931, respectively. As for power line carrier, the communication stack is still being developed. Mr. Scholer compared the AC charge rates and times for level 1 and level 2 and the DC charge rates and times for standard, fast and rapid charging. For DC charging, Mr. Scholer summarized connector sizes, the prospects for power line carrier, and inband signaling. He then outlined the next steps.

During discussion, some participants asked why SAE is concerned with the communication between the EVSE and utility. Others noted that the meter is sending or receiving information that is dedicated to the EV and this relates the EVSE, meter and the EV. These links should be clearly established by some organization, which may be SAE, IEEE, or other standards making body.

SAE J2894 Charger Grid Power Quality Jose Salazar, SAE, presented the status of SAE J2894, which takes the 1997 IWC recommendations on EV charging equipment power quality (see Attachment). The document is on its 3rd revision and the first draft is expected in April 2010. There are three main sections: charger power quality requirements, characteristics of AC service, and charger control. Mr. Salazar shared the EVSE vs. charger analysis conducted by Clipper Creek. During discussion, he suggested that the total harmonic distortion limit could be reduced based on Mesut Baran’s data. The team is cross referencing specific parameters with IEC, IEEE, and ANSI standards. With regards to parameters for microgrids, Steve Pullins, Horizon Energy Group, suggested not to equate single distributed generation resources such as portable generators with microgrids, which could meet utility power quality standards. In response to concerns about voltage stability due to cold load pickup from a transmission

5 perspective, Mr. Maitra proposed that utilities could share information on how they design their systems for cold load pickup.

Public Charging Stations – “Parktel System” Watson Collins, NE Utilities, invited Bobra Wilbanks, POM, to give a presentation on transaction systems in parking meters. Miss Wilbanks described the POM electronic meter (see Attachment). Among the benefits of the system are enforcement visibility, communications, payment options, integration, and in-house capabilities. Over 300,000 spaces are metered by POM worldwide. The POM system can use multiple payment options including tokens, smart cards, and Parktel (which allows credit card payment via cell phone using PayPal and Bluetooth). She showed how such a system would operate, including enforcement through conventional and Parktel website monitoring. During discussion, Miss Wilbanks indicated that it may be possible to send messages via cell phone or email and that the module could probably be installed in the EVSE.

Public Charging Stations – Payment Processing Systems Steve Pullins, Horizon Energy Group, presented on payment processing systems for public charging stations (see Attachment). He projects that there will be 5.5 million PEVs by 2020, but price clearing, settlement and billing are behind in the development. He summarized the findings and recommended guiding principles of the Utility Standards Board on payment and settlement. He discussed system fundamentals such as authentication, authorization, accounting, and validation, and presented design goals in a financial service model. He suggested that the financial clearing engine Tradescape, which is used by MySpace and clears one billion micro transactions per day, could be one solution. Customers need multiple payment options for convenience, minimum interaction time, and accurate billing. During discussion, Mr. Pullins reported the transaction costs for the financial clearing engine is about ¼ percent compared to 3-4 percent for credit cards. He also explained that interactions are needed between utilities because a customer traveling from San Diego to San Francisco could charge at several utility service territories along the way.

Announcements Joel Pointon, SDG&E/Sempra Utilities, announced that the California Public Utilities Commission is holding a meeting on “Alternative-Fueled Vehicle Rulemaking - R.09-08-009 Electric Vehicle Workshop: Accelerating the Installation of Home Charging Equipment” on March 16, 2010. Presentations will be on the web for viewing at http://www.cpuc.ca.gov/afv.

For Official Use Only 5 Utility Standards Board Scenarios

• Scenario 0: Leverage Existing Infrastructure • Scenario 1: Single Statement Billing • Scenario 2: Special PEV Rates • Scenario 3: Regional Same Price Everywhere Plan

For Official Use Only 6 Key Findings on Payment & Settlement

• Payment and settlement process costs could increase PEV charging costs enough to impact adoption rate. • Charging requirements can be met with existing payment and settlement systems with minimal modification – unless regulatory changes alter the requirements. • Changes to accommodate single statement billing will require process modifications – could be significant if charges are to be consolidated on the existing utility statement

For Official Use Only 7 Key Findings on Payment & Settlement

• Accommodating special PEV rates, reselling of electricity, carbon tracking, and/or taxes, could provide benefits, but could increase effective charging costs by 13% - 18%. • National/regional “same price” plans (cell phones) would impact systems and processes, and could raise the cost of charging > fueling an efficient gasoline powered vehicle. • Each $10M in utility investment for a new payment and settlement model results in an increase in annual PEV charging costs of approximately 18%.

EVSE

• Due to space constraints, one EVSE will be placed between every two parking spaces and will serve 2 parking spaces • The EVSE will be rated at 120/240V to avoid the need for a transformer

7 Future Renewable Electric Energy Delivery and Management Systems Center Cable Sizing

• Because of the high current rating of each EVSE, it is only feasible to supply 1 to 7 EVSE’s (2 to 14 chargers) from a single cable • Diversity • The amount of current that a charger draws depends on SOC • Depending on the distribution of initial SOC of the connected vehicle batteries, the total current in the cable will vary • Will this be enough to desire a larger number of modules to be connected to a cable?

• Goal: • Analyze the effect of current harmonics on the distribution transformer • Difficulties: • Not all chargers generate the same switching harmonics • There are currently no standards for regulation of charger current harmonics • Method: • 3 chargers: Prius w/ Hymotion kit, Escape, ATEC • Take samples over charging cycle • Analyze collected data for harmonic currents • Use IEEE C57.110 to analyze the effect on the transformer [5]

15 Future Renewable Electric Energy Delivery and Management Systems Center Prius Charger

• Use up to the 50th harmonic per IEEE 519 [6]

16 Future Renewable Electric Energy Delivery and Management Systems Center Escape Charger

18 Future Renewable Electric Energy Delivery and Management Systems Center Comparison

19 Future Renewable Electric Energy Delivery and Management Systems Center Transformer Derating

• IEEE C57.110 (2008) [5] • h is the harmonic order • Ih is the RMS current at harmonic “h” • “IEEE Recommended Practice for (amperes) Establishing Liquid‐Filled and Dry‐Type • F is the harmonic loss factor for winding Power and Distribution Transformer HL eddy currents Capability When Supplying Nonsinusoidal Load Currents” • PEC‐R is the per‐unit winding eddy‐current loss under rated conditions

• POSL‐R is the per‐unit other stray loss under rated conditions (neglected here)

• Irms is the total RMS current as calculated from C12 in the table

• PLL is the per‐unit load loss

• PLL‐R is the per‐unit load loss under rated conditions

• Imax is the max permissible RMS non‐ sinusoidal load current under rated conditions

20 Future Renewable Electric Energy Delivery and Management Systems Center Sample calculation for Prius

Conservative assumption for rated eddy-current loss

21 Future Renewable Electric Energy Delivery and Management Systems Center Results

• Carried out this analysis for each point in the collected data for each car

• Not expected –the Escape has more of a derating than the Prius, even though the THD was far less (17.3% vs. 6.5%) • Cannot make conclusions based on looking at THD alone

22 Future Renewable Electric Energy Delivery and Management Systems Center Harmonic Cancellation

• It has been proposed [3] that there is significant harmonic cancellation which occurs because of phase differences between chargers’ harmonic currents connected to the same system • In order to get a accurate derating for the transformer, we looked into this phase cancellation phenomenon

23 Future Renewable Electric Energy Delivery and Management Systems Center Method

• Harmonic cancellation for Prius and Escape together • Take random samples from each data set and combine them in two ways: • Compute the arithmetic sum of the magnitudes of the harmonic currents • Add the data points of each signal together, incorporating the phase information

• Compare Imax in each case to see the effect of harmonic phase cancellation

24 Future Renewable Electric Energy Delivery and Management Systems Center Results

25 Future Renewable Electric Energy Delivery and Management Systems Center Results

• Little change in the derating factor, thus it is justified to use a strict arithmetic sum of the magnitudes.

• Thus, a conservative value of 0.95 pu is used as the derating factor for the distribution transformer. • This suggests that the 250kVA transformer can only supply 0.95*250kVA or 237kVA if supplying non‐sinusoidal currents to the chargers studied here. • Still sufficient for charger load

26 Future Renewable Electric Energy Delivery and Management Systems Center Conclusions

• A supply circuit design has been developed for a prototype parking deck • 250kVA transformer –12 2/0 175A cables –24 modules –48 spaces at 32A max • Load diversity can be used to reduce the size the supply transformer • The harmonic currents for 2 commercially available PHEVs were characterized along with the ATEC Gen II Charger • The IEEE C57.110 standard was followed to obtain a derating factor of 0.95 pu for the transformer

Illustration does not include JARI/TEPCO latch area. SAE vs. JARI/TEPCO Grounding Strategy The fundamental difference between the SAE and JARI/TEPCO fast charge systems is the type of ground used between the charger and vehicle

 SAE uses an “earth” ground strategy while JARI/TEPCO uses a “reference” ground strategy ◦ An “earth” ground strategy requires the charge coupler ground pin and ground conductor be sized to handle fault current from the charger. This results in a coupler ground pin and ground conductor between the charger and vehicle similar in size (slightly smaller) than the coupler power pins and conductors. SAE vs. JARI/TEPCO Grounding Strategy ◦ A “reference” ground requires an isolation monitor to be included in the charger in order to monitor the isolation of the vehicle from the charger. A “reference” ground does not need to handle fault current so the coupler ground pin and ground conductor between the charger and vehicle may be similar to signal circuits.  UL has confirmed that they could List either option eTec DOE Project

• Power Line Carrier (PLC) is the long term approach –2 years out • Communication stack is still being developed (Smart Energy Profile 2.0) –one year off • ISO/IEC effort is aligned but has the same time frame. • Expect PLC auto qualified parts in 3 years (or less).

Rich Scholer ‐ SAE/IEEE/ISO/IEC 3‐4‐10 22 Communication Status AC Charge Rates

• Level 1 – (120V) 1.4 kW – PHEV takes 7 hours (starting at 0% SOC) – BEV takes 17 hours (starting at 20% SOC) • Level 2 – (240V) up to 19.2 kW (80A) – Most installations are connected to 40A CBR (7.68 kW) – PEVs include 3.3kW chargers • PHEV takes 3 hours to charge • BEV takes 7 hours – PEV includes 7 kw charger • Advantage ‐ Closer match to EVSE capacity, faster charge times (1/2 of 3.3 kW) • Disadvantage ‐ More weight and cost to PEV

Rich Scholer ‐ SAE/IEEE/ISO/IEC 3‐4‐10 23 Communication Status DC Charge Rates • DC Standard (up to 20 kW –80A). – Same connector as Level 1 & 2 – Adds off‐board charger to EVSE – Requires additional communication (J2836™ & J2847, J2931) – PHEV charges in 22 minutes (0 to 80% SOC since faster than 1C rate) – BEV charges in 1.2 hours (20% to 100% SOC).. • DC Fast (up to 80 kW ‐ 200A). – Standard connector with two more terminals (combo) – – PHEV charges in 10 minutes (45kW for 10 minute rate –0 to 80% SOC) – BEV charges in 20 minutes (20% to 80% SOC since faster than 1C rate) • DC Rapid (up to 200 kW ‐ 400A) – 2nd connector for BEVs only – – Location in fuel door position – Charge in less than 10 minutes – Common with electric trucks/buses Notes: BEV always starts at 20% SOC, PHEV can go to 0% SOC since hybrid mode is available.

Rich Scholer ‐ SAE/IEEE/ISO/IEC 3‐4‐10 25 Communication Status PLC doesn’t meet some timing (for DC) & may not meet performance (what do we do? –what are our options??) • Short term ‐ Propose using the J1772™ control pilot and direct communication between the PEV and EVSE off‐board charger “inband signaling”. • If Eaton is right PLC won’t work with DC anyway. • wants separate DC messages from utility messages.

EPRI IWC Quarterly Meeting PHEV Working Group Background

• The objective is to take the 1997 EPRI IWC “EV Charging Equipment Operational Recommendation for Power Quality” legacy document, update and publish under an SAE recommendation • EPRI IWC Recommendation was done at the December 2008 Meeting • April 2009 the SAE Hybrid Committee approved the recommendation to create an SAE document. • The new document created was SAE J2894 • The “PQ” taskforce is being co-chaired by Gery Kissel (GM) and Jose Salazar (SCE) SAE J2894 Status • Currently on the third revision of the document • Document has three main sections: – Charger PQ Requirements – Characteristics of AC Service – Charging Control • What the team is working on: – Cross referencing specified parameters with other standards such as IEC, IEEE & ANSI – Adding missing parameters such as “utility voltage distortion” & revising existing parameters such as “maximum inrush” current limits – Revising the section on “portable generation” to include distributed generation resources such as photovoltaic systems – Revising the “cold load pickup” procedure to address system voltage at high PEV penetrations. (Distribution vs. Transmission) • Final draft is expected by early April 2010 EVSE vs. Charger Analysis

# Specification Level 1 Level 2 Off Board On Board note EVSE EVSE DC EVSE A/C to D/C 4.1 Displacement 1. Only the main A/C to D/C power converter should have to meet the power factor, the Power Factor AC EVSE’s own power supply should be considered an ancillary load, just like other minor loads on the vehicle.

√ √ 2. A maximum power limit could be established above which any component must meet this requirement, it is conceivable the EV might have a power conversion component for other functions that are many 100’s of Watts, and it would be undesirable for these to have low PF. I think that other industries follow this threshold requirement (like various office building equipment?), is a lower limit specified in IEEE 519? 4.2 Power Conversion should we consider changing the definition to be the ratio of the output DC power and the Efficiency input AC power but only for the A/C to D/C converter stage? The definition is currently √ √ from the EVSE input to the DC output at the Traction battery buss. The EVSE might use power for all kinds of ancillary stuff and should not be included. 4.3 Total Harmonic essentially the same comments as 4.1 √ √ Current Distortion 4.4 Current Distortion essentially the same comments as 4.1 at Each Harmonic √ √ Frequency 4.5 Inrush Current 1. One typical reason A/C to D/C converters have input capacitance is to reduce conducted emissions in order to meet FCC requirements, but these are usually small. Inrush current can be significant for the input stage storage capacitors when the EVSE contactor closes.

√ 2. I do not think there is too much risk of tripping circuit breakers or premature component failures, however dimming lights was the original concern as I recall – users might see that as scary or create unnecessary concern

3. Off board DC EVSE will only have surge when the circuit breaker is switched on as it is always connected, so it should not have to meet this criteria.

If Level 1 introduces a potential inconvenience for the user. This is because the user may optionally plug into the EV 1st, and then the wall socket. The EVSE will unnecessarily go into CLP mode creating user confusion. Adding a button to the EVSE is not a fix, as it adds unnecessary cost and the EVSE does not act consistently. 6.3 Load Rate (Soft As with requirement 4.5, the issues is that dimming lights might create customer concern. √ √ Start) Should we specify a maximum rate, something like 10Amps/second from AC lines?

EVSE rating expressed in KW

Hypothetical scenario; parking structure with 30 – 6.6kw EVSE units

1) Each unit could be fed with an individual 40 amp 208 volt branch circuit. 2) Units could be powered in groups of two with 15 – 80 amp feeders, (no application of the demand factor table). The 6.6kw EVSE units have to be taken at 125%; 13.2kw x 1.25 = 16.5kw divided by 208 volt = 79 amps is the minimum rating required of the feeder. If the units are equipped with in and out terminal blocks rated for 75° C, #4 copper THHN conductors could be used to supply each group of two stations. Each of the 12 feeders would be protected by an 80 amp breaker. 3) Units could be supplied in groups of six with 5 – 175 amp feeders, (demand table allows adjustment to 90%). 6.6kw x six units = 39.6kw divided by 208 volt = 190amps @ 90% = 171 amps. If the units are equipped with in and out terminal blocks rated for 75° C, 2/0 copper THHN conductors could be used to supply each group of six stations. Each of the 4 feeders would be protected by a 175 amp breaker. 4) Dual units could be supplied in groups of 3 as illustrated below;

Each of the above illustrated feeders could be installed with 2/0 copper conductors and protected by a 175 amp breaker under the demand table. Without the application of the demand factor table the wire would have to be 250mcm with protection at 250 amps.

1

The illustration on page one indicates two configurations for 5 different feeders to EVSE equipment. Additionally, there is a 100 amp feeder to a lighting panel with a calculated load of 60 amps.

A 2008 NEC compliant calculation could be done as follows;

30 – 6.6kw units total 198kw @ 125% equals 247.5kw divided by 360.256 = 687a. add the 60 amp general lighting and receptacle and a calculated 747 amp load requires an 800 amp service. A service with an 800 amp main breaker could employ any combination of feeders and branch circuits to the loads.

Apply the demand factor table and the calculation could look like this;

Five 175 amp feeders could serve groups of six units, and the sixth handle would feed the house panel. Only three of the feeders can be evenly distributed among the phases of the service, so 18 – 6.6kw units totaling 118,800 watts divided by 360.256 = approximately 330 amps. The remaining 12 units cannot be evenly portioned between phases of the service and should be considered as follows; 12 – 6.6kw units totaling 79,200 watts divided by 208 volts = 380 amps. 330 amps balanced, plus 380 amps that cannot be balanced equals 720 amps. Apply the demand factor of 70% for 30 units, and the resulting 504 amps plus 60 for the house panel allows a 600 amp service instead of 800 amp.

A 198kw charging load running full tilt on a three phase 120/208 volt service equals approximately 550 amps. Add 60 amps for the house panel and the calculation is 610 amps. The demand factor table allows the installation of a 600 amp service, based on the premise that there is little chance that all 30 chargers will operate simultaneously at 100% load. Other applications of the demand factor table may result in even more dramatic reductions in service equipment ampacity requirements. It is important to remember that the code contains provisions that are considered necessary for safety. Attention to proper wire size and overcurrent protection will assure safety, but may not result in an installation that is efficient, convenient, or adequate for future expansion.

Early models of the SAE J1772 included an open space

Some speculated that this could be a provision to deliver 3 phase power to the on board inverter/charger LEVEL 2 CHARGING LEVEL 2 CHARGING

SAE standard J1772 has been finalized and released . . . without an open space for an additional power transfer pin

Apparently three phase power delivery will not be supported by the J1772 LEVEL 2 CHARGING

According to the SAE standard, power transfer pins are rated for 80 amps

Commercial EVSE units with a 70 amp 208 volt branch circuit could deliver power at a rate of 11.5kw

At three phase it could have been 20kw HOME BASED EVSE

The industry seems to be leaning toward EVSE units that require a 40 amp branch circuit

Because EVSE is considered a continuous load, a 40 amp 240 volt unit is limited to power delivery at a rate of 7,680 watts DUAL VOLTAGE RATING

40 amps at 208 volts is limited to a power transfer rate of 6,656 watts

Most units will probably be designed for use at 208 and 240 volts

Some early release vehicles will have 3.3kw chargers upgradeable to 6.6kw HOME-BASED CHARGING

20 amps at 240 volts could supply the 3.3kw charger (16a x 240v = 3840w max)

An electrical contractor speculated that he would have to provide a 1,200 amp service at a parking structure to support 30 – 6.6kw chargers! 6.6kw charger in California FEEDERS AND SERVICES

NEC article 625 contains no provisions for load diversity when calculating EVSE feeders and services

The division started researching charge rate data gathered by users of battery powered vehicles and electric utilities EXISTING DATA

Data collected from various industrial and warehouse charging operations for material handling equipment revealed reason to apply a diversity factor

There is no existing data for mass charging of Lithium Ion batteries DIVERSITY FACTOR TABLES

Number of EVSE stations Sum of EVSE station ratings (%) 1-4 100 5-8 90 9-14 80 15-30 70 31-40 60 41 plus 50 EXAMPLES OF USE

30 – 6.6kw units @ 208 volts = 198kw 198kw @ 125% = 247.5kw A 120/208v three phase service could deliver this amount of power at 687 amps, (247,500 / 360.256)

Single phase loads are more efficiently served by a three phase service REALITY QUESTION

Are these 30 – 6.6kw charging stations likely to operate simultaneously at maximum load for more than three hours? ANOTHER CONTRIBUTING FACTOR

The electrical service to this parking structure is likely to supply lighting and other loads SERVICE CALCULATION

Five EVSE feeders and a house panel feeder EXAMPLES OF USE

Five feeders, each one serves 6 – 6.6kw EVSE units;

Each feeder can be taken at 90% (see handout) 6.6kw x six units = 39.6kw divided by 208 volt = 190amps @ 90% = 171 amps. Feeder conductor size could be 2/0 copper with 175amp breakers Without the demand factor table these feeders would have to be at least 250mcm conductors protected at 250 amps! SERVICE CALCULATION

NEC article 210.11(B) suggests that the load always be portioned evenly between feeders and branch circuits.

This load scenario cannot be evenly portioned across all three phases of the service. AUTHOR’S INTERPRETATION

The portion of the calculated load that can be evenly distributed can be divided by 360.256

18 units = 118,880 watts divided by 360.256 = approximately 330 amps AUTHOR’S INTERPRETATION

The remaining 12 units cannot be evenly distributed, and should be taken at 208 volts

12 units = 79,200 watts divided by 208 = approximately 380 amps COMPLETED CALCULATION

330 amps balanced + 380 amps that can’t be balanced = 720 @ 70% per the demand factor table = 504 amps

Add a small sub panel for lighting and convenience receptacles, and a 600 amp service will be adequate OTHER CALCULATIONS may result in more dramatic reductions than this example Remember that the code contains provisions that are considered necessary for safety.

• BEVs - Offer the combo receptacle as "std“ – This starts with J1772™ Level 1 / 2, then the receptacle adds two DC terminals. – This allows any Level 1 / 2 plug to connector and the DC standard (150A). – Smaller than current BEV offerings (need to confirm). – This combo also works for three phase. Need to present to ISO/IEC. • Include the 360A connector (DC Rapid) as the 2nd vehicle connector. • All cases are included with two receptacles on the vehicle. • The J1772™ task force can offer three infra connectors to meet everyone’s needs (Std, Fast & Rapid).

• Are there any EVSEs planned with 80 kW off-board chargers (200A)? – TEPCO is 50 kW (150A). – 80 kW is 60% oversized for 150A requirement. • 90% of PEVs will be PHEV. – Why penalize 90% of the PEVs with “two” oversized terminals (30% larger, 2 to 3 times more cost)? • 80 kW vs. 50 kW time savings: (not worth the added size, cost, weight, etc.) – BEV1 – 13 minutes vs. 20 – BEV2 – 11 minutes vs. 17 – BEV3 – 37 minutes vs. 57 – BEV4 – 1.2 hours vs. 1.8 • 10 minute charge – BEVs need 140 kW not 80

This document is the 11th of 12 parts of the official compilation and publication of the adoptions, amendments and repeal of regula- tions to California Code of Regulations, Title 24, also referred to as the California Building Standards Code. This part is known as the California Green Building Standards Code. The California Building Standards Code is published in its entirety every three years by order of the California legislature, with supplements published in intervening years. The California legislature delegated authority to various State agencies, boards, com- missions and departments to create building regulations to implement the State’s statutes. These building regulations or standards, have the same force of law, and take effect 180 days after their publication unless otherwise stipulated. The California Building Standards Code applies to all occupancies in the State of California as annotated. A city, county or city and county may establish more restrictive building standards reasonably necessary because of local climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building standard(s) must be filed with the California Building Standards Commission to become effective and may not be effective sooner than the effective date of this edition of the California Building Standards Code. Local building standards that were adopted and applicable to previous edi- tions of the California Building Standards Code do not apply to this edition without appropriate adoption and the required filing. Should you find publication (e.g., typographical) errors or inconsistencies in this code or wish to offer comments toward improving its format, please address your comments to:

ACKNOWLEDGEMENT

The 2007 California Green Building Standards Code (Code), first adopted in July 2008, was developed through the outstanding collaborative efforts of the Department of Housing and Community Development, the Division of the State Architect, the Office of the State Fire Marshal, the Office of Statewide Health Planning and Development, the California Energy Commission and the Building Standards Commission (Commission). This collaborative effort included the assistance of the Commission’s Green Building Code Advisory Committee and many other state agencies and volunteers that worked tirelessly to assist the Commission in the production of this Code.

2008 CALIFORNIA GREEN BUILDING STANDARDS CODE iii EFFECTIVE USE OF THIS CODE

This format of this code is common to other parts of the California Building Standards Code and contains building standards appli- cable to occupancies which fall under the authority of different state agencies. Occupancies and applications under the authority of a specific state agency are identified in Chapter 1, Sections 103 through 106. Sections of this code which are applicable and adopted by each state agency are identified in the Application Matrix for each state agency, contained in Chapter 11. The following outline may be helpful as a guide to establish which provisions are applicable to a specific occupancy. 1. Establish the type of occupancy. 2. Verify which state agency has authority for the established occupancy by reviewing the authorities list in Sections 103 through 106. 3. Once the appropriate agency has been identified, find the application matrix for that agency in Chapter 11. 4. The application matrix will list the green building measures adopted and provide the effective date and other information re- garding each green building measure applicable to the established occupancy. 5. Each green building measure listed in the application matrix has a section number which correlates with a section number in Chapters 4 through 8. 6. More information is available for each green building measure listed in the application matrix in the correlated sections con- tained in Chapters 4 through 8.
