Why NEMA?
The Electrical Vehicle Supply Equipment
(EVSE) Section Story
The Association of Electrical and
Medical Imaging Equipment Manufacturers
EVSE story
NEC, UL, CSA, LEED, IGCC, IECC Requirements for EVSEs without EVSE representation
Active stakeholders: anybody but the EVSE industry!
EVSE – new technology in need of infrastructure
Infrastructure requires
 Standardization: interoperability, safety of product & installation
 Financial help: legislative, regulatory, education
This is what NEMA does!
The Association of Electrical and
Medical Imaging Equipment Manufacturers
EVSE story
Asked NEMA members privately tentative Yes
Looked for non-members - intrigued
Organized Workshop
Green Light to start a new EVSE Section

EVSE story
2011 new EVSE Section formed
 Look around to identify battlefields layout
 Small budget
Timely!
The Association of Electrical and
Medical Imaging Equipment Manufacturers
EVSE story
NEC- article 625 complete revision
NIST - 2 draft regulations for NCWM.
Wrong model : the fuel pump!
 Hb130 – Method of Sale
 Hb44 – Electricity – Measuring Devices
Utilities (esp. CPUC) – subtractive billing
to influence charging behavior

EVSE story
SGIP – PAP22 –submetering- esp. EVSE
ANSI C12- submetering subcommittee
ANSI EVSP – standardization roadmap
 NEMA EVSE Embedded Metering Guide
 NEMA Networks Interoperability (roaming)
CSA and UL – competing on certification
NEMA - 3-national fast-track
harmonization (Canada, Mexico, US)
The Association of Electrical and
Medical Imaging Equipment Manufacturers
2014 NEMA EVSE Section
Harmonized UL/CSA/ANCE certification stds.
New metering concepts for NIST/NCWM
Recognized party for CPUC in defining
residential metering
CA law waiting for NEMA’s networks roaming
NEC article 625 maintenance
Opposed regulations for special EVSE installer
certification
Got LEED credits for EVSEs
The Association of Electrical and
Medical Imaging Equipment Manufacturers
Why the EVSE story?
Submetering requirements everywhere –
no manufacturers fighting for them!
New vectors driving the growth,
i.e. DR, Energy efficiency
Issues calling for industry consensus:
definitions, performances, functional
interoperability, certification, etc.
