57 NIST Work on Methods of Sale March 2014 Copyright 2014 ChargePoint, Inc. 1

58 Methods of Sale Regulations + When you are in commerce and you aren t regulated as a utility then you are regulated by Weights and Measures + Weights and Measures laws are adopted and enforced stateby-state, but most states start with NIST documents or adopt them wholly + NIST Handbook 130 regulates Methods of Sale; meaning if charging services can be sold by kwh, time, sessions, or subscription + NIST Handbook 44 regulates the equipment; i.e.: the EVSE Copyright 2014 ChargePoint, Inc. 2

59 General Process for Handbook Changes + Proposed changes to HB130 and HB44 happen during the year by a working group. Changes are being developed by the NIST s US National Working Group on electric vehicles + In July every year, HB130 and HB44 changes are voted on by the National Conference of Weights and Measures + Last July, the National Conference passed HB130 that allows sale of EV services by any combination of KWH and fees + NIST Handbook 44 regulates the equipment; i.e.: the EVSE. NIST is expected to submit an HB44 draft in That draft is now in development by a technical working group Copyright 2014 ChargePoint, Inc. 3

60 Handbook 44 The NIST draft changes for Handbook 44 include things like: Accuracy of measurement Verification procedure Displays Receipt printers Response to power interruption Copyright 2014 ChargePoint, Inc. 4

61 Handbook 44 Directions from January Working Group Meeting Pricing can change during a charging session Electronic receipts will be adequate Testing will be done by vehicle simulator at 2% No battery backup will be required charging sessions will terminate at power failures The next USNWG meeting is April 29 th and 30 th in Sacramento. The National Conference on Weights and Measures has the USNWG work on HB 44 classified as a Developing Item Copyright 2014 ChargePoint, Inc. 5

62 Regulatory Dynamics + Now we need states to adopt HB130 and we need the working group to finish the development of HB44 + Without HB130 adoption, it is not clear where you can sell EV services + That s why we should move forward fairly quickly Copyright 2014 ChargePoint, Inc. 6

70 Effects of adding one PEV to one home 11.5 kw Start 50%, at lowest price and 50% DRLC, then Increase charge to 100% when DRLC is done Demand Response Load Control (DRLC) 100% Price 0.150/kWh 0.125/kWh 0.100/kWh Charge TCIN Connected time DRLC 11 kw 10.5 kw 10 kw 9.5 kw 9 kw 8.5 kw 8 kw 7.5 kw 7 kw 6.5 kw 6 kw 5.5 kw 5 kw 4.5 kw 75% 50% Price 4 kw 3.5 kw 3 kw 2.5 kw 2 kw 25% Home Load 1.5 kw 1 kw 4 pm 6 pm 8 pm 10 pm 12 pm 2 am 4 am 6 am 8 am 10 am noon 2 pm 0.075/kWh 0.050/kWh Home Load 0.025/kWh Time 7

71 Price and DRLC Summary These are tools applied to existing loads (thermostats, hot water heaters) and habits (appliances amenable to DRLC). e.g. Not cooking, not plasma TVs, etc. in peak periods Expanding these to include PEV s is not sufficient. They will work as one, maybe two PEVs are added to the distribution feed and transformer that s connected to 5-10 homes in a subdivision. PEVs are connected during peak periods. Current solutions is Scheduled or delayed charging. We all know this just shifts the peak. Price, DRLC, Scheduled charging are not long term solutions. 8

72 What are the new tools Smart Energy Profile FlowReservation (J2836/1 & J2847/1) a) PEV asks for Energy, Power level and Time Charge Is Needed (TCIN) b) Receives response from Utility (Home Area Network/ Energy Management System, etc) on what is available 2. Distributed Energy Resource (DER) (J2836/3 & J2847/3) a) Vehicle to Grid (V2G) b) Vehicle to Load (V2L) a) Includes Vehicle to Vehicle (V2V) & Vehicle to Home (V2H) c) Includes on-board or off-board inverter approaches 3. Metering function set (existing tool with SEP1.x) intent is to complement FlowReservation to level loads. 9

116 Brief History of SAE PEV-EVSE Interoperability Progress: August 2012: Ted Bohn started running J2953 meetings and stepped up the pace of meetings (monthly, ramping up to weekly at times) October 2013: J2953/1 is fully published; J2953/2 in final stage of publishing. (Only pilot/prox basic AC charging interoperability coveredno digital communication) November 2013: J2953 version 2 draft started; Focus on DC charging requirements, test procedures and digital communication functions May 2014: DOE AVTA E funded PEV EVSE Interoperability testing at Intertek Plymouth MI ~ 11 vehicles, 13 EVSEmfgs, ~3 weeks each=33 weeks total December 2014: Estimated completion of first draft J2953/1 v2 March 2015: Estimated completion of first draft J2953/2 v2 June 2015: PEV EVSE DC charging interoperability testing? 2

117 Interoperability Document Structure: J2953-Plug-In Electric Vehicle (PEV) Interoperability with Electric Vehicle Supply Equipment (EVSE) J2953/1 Requirements, J2953/2 Procedures Interoperability tests are most concerned with start up, shut down and transitions in between various pilot signal states. Interoperability is differentiated from compliance and conformance in that interoperability is limited to a fixed combination of a single EVSE PEV (not universal interoperability unless all combinations are tested.) EVSE compliance to J1772 v5 is presupposed; (GridTest verified optional) PEV compliance to J1772 v5 is not defined, but may be added to J2953 v2 Mechanical interoperability is limited to insertion/removal force measured, check latch functions include proximity interlock on latch button 3

118 Interoperability Document Structure: J2953/1-Plug-In Electric Vehicle (PEV) Interoperability with Electric Vehicle Supply Equipment (EVSE) J2953 Contains 3 Tiers of Interoperability: Tier I: Charge Functionality (Normal charging, normal supply conditions) Tier II: System Robustness Testing Indefinite power source variation event static voltage/frequency adjusted before charge session begins until test is complete Momentary power source variation event dynamic voltage and frequency adjusted during energy transfer section of session. Tier III: Non Essential Features Tests (EVSE mfg specific features timers) J2953/1 Appendix A (Pass/fail requirements analysis) J2953/2 Appendix A (Capacitance tests, results forms) 4
