For the first time ever, a PEV was named 2013 Motor Trend Car of the Year.2013 Motor Trend Car of the Year Blink charging stations to charge $5 for one charge to members and $8 for one charge to non members. Walgreens set to open 800 EV charging stations this year and will be charging $1-2 per hour. Current Trends

10. ©2013 Fluke Corporation 10 6,268 public electric charge stations in United States today. Current State

11. ©2013 Fluke Corporation 11 EV Market Projection 1.8M PEVs in US and 3.8 M PEVs worldwide by 2020. PEV Market to grow 40% CAGR while vehicle market to grow by 2%. US leader in PEV market with 46% share in BEV and 70% in PHEV.

12. ©2013 Fluke Corporation 12 Growth in EV adoption has made state authorities realize the need for creating standards for electrical vehicle charging stations. NIST U.S. National Work Group (USNWG) formed to develop standards for EVSE (EV Supply Equipment) and to ensure that the prescribed methodologies and standards are traceable to the International System of Units (SI) Need for Calibrators

13. ©2013 Fluke Corporation 13 Develop a standard Method of Sale for electrical energy as KWH. o Based on KWH usage o NIST HB 130 Address legal metrology requirements to address equipments used in EV refueling system. o NIST HB 44 to have the specifications tolerances and other technical requirements that electric charging stations must meet. Create test procedure and traceable field testing. Major Areas of Concerns for USNWG

14. ©2013 Fluke Corporation 14 There will be a need for an instrument that can calibrate electric charge stations. Calibration required irrespective of whether charge stations are free or fee based. Calibration required to make sure that the person charging the EV gets value through charging. Discussion

17. ©2013 Fluke Corporation 17 Calibration standard is a more accurate meter to monitor in line with charging station? Calibration standard is a source device where it would be necessary to disconnect the power source and connect in? It would be desirable to be able to interface calibration standard safely to any type of plug from the charging station Intrinsically Safe? Calibration Standards - What does Industry want? http://www.fluke.com/fluke/usen/solutions/intrinsically-safe/default.htm

18. ©2013 Fluke Corporation 18 Transformer – usually an integral part of the meter station Meter – Acceptance tolerance = 1%, so a calibration standard would need to be 0.3% to 0.25% Load Testing – need to be able to apply a load that test at 0.5 Amps Power Factor test – tough test, would require a source where the phase between the voltage and current to the meter KWH – energy (Joules or KWH) depends on time, standards do not contain performance verification of timer circuitry Charging Station Conformance

19. ©2013 Fluke Corporation 19 The present Weights and Measures community would require training on: Electrical concepts Safety – (segregation of gasoline and electrical standards) Test procedures with calibration standards Training

20. ©2013 Fluke Corporation 20 Both charging station manufacturers and organizations/entrepreneurs installing stations need to be educated on the legal metrology aspect of electric vehicle chargers Need to communicate legal metrology requirements to manufacturers Many have no accuracy specifications Some Manufacturer’s accuracy specifications do not meet Handbook 44 and 130 requirements Education/Outreach
