Summary of active documents in 7 categories:1. New document “J2836 - Instructions for PEV Communications, Interoperability and

Security Documents”1st cut of the document is posted with meetings soon. The intent is to summarize Bubble & Venn diagrams, then instructions, history and future plans for the documents based on functional objective (e.g. (1) if I want to do V2G with an off-board inverter, what documents and items within them do I need, (2) What do we intend for V3 of J2953, etc…)

2. Diagnostics - J2836/4 Use CasesCompleted clean-up and posted, determining if other items can be included (diagnostics), then start the ballot cycle.This includes the analogue diagnostics for the Control Pilot & Prox for opens, shorts low and high at various points.Plan to re-open later for additional charging requirements (AC, DC, WPT …)

3. Customer to PEV J2836/5 Use Cases, U10 for payment is posted & 1st meeting to be scheduled soon.Next steps are messages/protocol documents

4. DC Charging (J2847/2 - V4)Continuing to outlining variations to messages/signals/enumerations between SAE and ISO 15118 ED 2. Working with ANL & JRC to determine when the Golden Test Device will be available and how it will be used to validate Test Cases.



Categories (cont)5. PEV as a Distributed Energy Resource (DER) - Hank McGlynn is lead

J2836/3™ - V2 - Use Cases for the PEV Communicating as a Distributed Energy Resource (DER)

Topic to task force is complete and in Hybrid committee ballot.J2847/2 updates are next (for off-board inverters).J3072 published and still working authority and testing items.UL 9741 V1 is published and plans to include PEV on-board inverter effects.

6. Security – Gorden Lum is leadJ2931/7 – V1 – Security details - Continuing monthly meetings and reviewing other security documents for reference.

7. Interop – Ted Bohn is leadJ2953/1 – V2 - Interoperability requirementsJ2953/2 – V2 – Interoperability Plan and ReportJ2953/3 – V1 – Test Cases (DC charging is 1st, potentially AC Test Cases)Meetings to review Test Cases, both AC and DC and any potential changes to J1772, V7.Golden Test Device (GTD) expected to be released end of 2016 for validation of test cases, then inclusion in J2953/3.Test Event #5 in Korea in November 10th & 11th along with ISO 15118 meetings Nov 9th.

Communication and Energy Transfer Combinations



Disclaimers:1. No claim is made on “issues, problems, preferences, etc.” with any

combinations. 2. Only “comments” are included.3. The intent is to summarize all expected systems (in the home) that is also

intended for public locations with Energy Management System to grid. 4. No claim is made that this is complete.

AC Charging



AC Charging – DR control of EVSE(SEP1.x or SEP2 DR signal)

Comments:• No indicator of when the PEV connects?• No info on what power level does the PEV need?• No info on how long is the power needed?• No acknowledgement (feedback) of DR accepted

or rejected (customer opt out) by the vehicle.• Not clear on the DR signal frequency/latency.

EMS Signal needs to adjust power flow every minute to maybe three minutes (not a 15 minute interval)





AC Charging (SEP1.x vs SEP2)



AC Charging w/ ISO 15118 (PEV to EVSE)

AC Charging – ISO 15118 High Level Communication (HLC) NAFTA vs. EMEA vs. SEP2

Comments:• SEP1.x is communication between the Smart Meter and ESI

– Time of Use Price (TOU – months ahead), Critical Peak Price (CPP - day ahead) or Real Time Price (RTP – minutes ahead) plus Demand Response (DR)

• SEP2 is communication between PEV and Utility. – SEP2 PLC on Control Pilot (between PEV and EVSE), then SEP2 PLC or Wi-Fi

or ZigBee to ESI– Requires bridge at EVSE to ESI or Utility– Same as SEP1.x price and DR, adds FlowReservation (request power level,

energy amount required and “both initial & actual” Time Charge is Needed (TCIN) for charge session, dynamically adjusts to actual values, with acknowledgement to utility)

• 15118 is communication between PEV and EVSE. – PowerLine Carrier (PLC) on Control Pilot– Requires gateway (not bridge) at EVSE for Utility or home interface to other

protocols.

Other options (optimized charging)

• RTP program where both positive and negative priced are available

– Negative prices (utility pays for a source to use excess energy) can be used for vehicle charging

• Clean energy can be identified so PEV can charge when this is available



What else? DC Charging (in the home)



Xtreme Fast Charge (XFC) effects in the home

• BEVs may be charged similar to IC vehicle refueling (once a week instead of “every opportunity”).

• 7 kW/vehicle may be once a week instead of daily

– Steady 7 kW for 10-12 hrs duration (50 kWh for 150 miles) once a week

– instead of 2 hrs daily (10 kWh for 30 miles)

– Two BEVs = 14 kW for 12 hours!





AC DER (on-board inverter)



DC DER (DC Discharging)

Telematics – Indirect communications(macro Charging control – save XX MW)



OpenADR2 for DR signal to OEM Central Server using

Hot Spot Prediction

Wireless Power Transfer (WPT)(additional items)

1. Wireless communication (instead of PLC)

a) IEEE 802.11n (static WPT, 802.11p for dynamic)

2. Additions:

a) Alignment

WPT Charging Initial Compatibility



Procedure to communicate Initial compatibility information between EVCC and

SECC

Can have several vehicles approaching several WPT choices:

SECC

SD SD SD

①

Circular DD Solenoid

②

①SECC send several supported method to EV.

②EV select one of the supported method to use and send it to SECC.

Using Service detail response message

Using Payment service selection request message

Otherwise, EV rejects the SECC request. By this procedure, the method of fine positioning, pairing, initial alignment check to use should be chosen.
