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.

Communication and Energy Transfer Combinations
11/16/2016Rich Scholer - SAE Communication and
Interoperability Task Force12
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
10/11/2016Rich Scholer - SAE Communication and
Interoperability Task Force13
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)
10/11/2016Rich Scholer - SAE Communication and
Interoperability Task Force16
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

Interoperability Task Force22
What else? DC Charging (in the home)
10/11/2016Rich Scholer - SAE Communication and
Interoperability Task Force23
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!
