The Canadian counterpart to the American National Standards Institute provides a platform for public comment on its consensus products:
The platform provides an intuitive way into a draft standard and a way to comment upon it.
Today we take note of a product farther up the pipeline regarding electric vehicles. Earlier this year the CSA Group (CSA America Standards Inc.) has given public notice of its intent to develop a new standard to be titled: CSA C22.2 Electric Vehicle Energy Management Systems. From the ANSI New Project Initiation Notification announcement:
Project Need: CSA Group has been approached by the industry to develop standards and technical requirements for the deployment and safe operations of EVEMS within the Canadian regulatory structure and utility requirements. This project is intended to address this need and the existing gap in the standards required for the operation of EVEMS.
Stakeholders: Regulators, manufacturers, utilities, and industry associations.
With the rapidly growing penetration of Electric Vehicles (EVs), there is an increased demand to develop technology to support the efficient and safe charging of the vehicles with less impacts on the current electrical distribution infrastructure during peak charging times. In addition to managing the demand for electricity, EVs can become energy storage devices for the grid. This possibility raises the need to view EVs and related charging equipment as an Electric Vehicle Energy Management System (EVEMS). An EVEMS is a means of controlling electric vehicle supply equipment loads comprised of any of the following: a monitor(s), communications equipment, a controller(s), a timer(s) and other applicable device(s). Today there is no clear standard or guideline to help define the safe operations of an EVEMS although individual standards exist for some of the components within the EVEMS.
The announcement was filed in February 2019. CSA Group has only filed formal notification required in ANSI’s due process requirements*.
The project is on our watch list. Many research universities are on the receiving end of electric vehicle research projects and also have large campus transportation fleets that are converting to electric vehicles. Should any public review drafts be released we typically coordinate our response with the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly.
CSA Group consensus products are also on the standing agenda of our periodic Global teleconferences; open to everyone. See our CALENDAR for the next online meeting.

Underwriters Laboratories (UL) has launched a new revision cycle for its standard — UL 9540 Standard for Safety for Energy Storage Systems and Equipment — which sets the standard of care for energy storage systems that are intended to receive electric energy and then to store the energy in some form so that the energy storage system can provide electrical energy to loads or to the local/area electric power system up to the utility grid when needed. The list of proposed changes to the 2016 edition is lengthy and will be meaningful to electrical storage technologies specified, installed and operated in every industry:
(a) Addition of UL 1973 to Appendix A Component List
(b) Addition of ISO Functional safety standards,
(c) Revision of grounding and bonding system construction,
(d) Revision of the strength of enclosure walls and supports requirements,
(e) References to required signage and instructions,
(f) Deletion of nonmandatory language throughout standard,
(g) Revision of scope language for clarity,
(h) Revisions to the fire detection and suppression section,
(i) Proposed addition of new 32.4.6,
(j) Revision to mechanical tests for clarification,
(k) Clarification of 1.2,
(l) Revision of 6.4, harmonization with other existing standards,
(m) Enclosure materials for outdoor installations,
(n) Short circuit exposure evaluation,
(o) Clarification of scope,
(p) Clarifications of component and normative reference section,
(q) Clarification of corrosion requirements for enclosures,
(r) Revisions to make the use of term “energy storage system” consistent throughout entire standard,
(s) Clarification of instructions for worker safety,
(t) Revisions to clarify intent and application of 11.1 and 12.2,
(u) Clarifications of system requirements for where the system is installed,
(v) Clarification of the intended environment,
(w) Clarification of bonding and grounding requirements,
(x) Clarifications of 17.1 and 18.1,
(y) Clarification of 21.1,
(z) Clarification of 32.2.2,
(aa) Clarification of 40.4 and 40.5,
(ab) Clarification of 11.2,
(ac) Addition of requirements for residential ESS,
(ad) Addition of production checks on electronic controls,
(ae) Addition of requirements for quality control of production,
(af) Additional testing options,
(ag) Addition of a wall mount fixture test for wall-mounted ESS,
(ah) Addition of Normative Appendix D for alternative lead acid or ni-cad battery system evaluation,
(ai) Revision of 12.3 to add short circuit protection,
(aj) Addition of Informative Appendix E for Guidance on Capacity and Separation Distance Limits for ESS,
(ak) Addition of EMC testing,
(al) Revision of utility grid interaction reaction requirements,
(am) Clarification of the scope,
(an) Clarification of Vapor concentration requirements,
(ao) Addition of emergency contact marking,
(ap) Clarification of flame test surface area
aq) Addition of 8.2 and Appendix F 2, Revisions for electrochemical ESS above 20 kWh.
It is easier to work with the strike-and-bold version posted on ANSI’s website so you can see the changes in context. A new redline was released December 20th; linked below:
Comments due January 19th.

We are happy to discuss this, and any standard any day at 11 AM Eastern time. We typically collaborate with the IEEE Education & Healthcare Facilities Committee on formulating comments on standards of this nature. We also set aside an hour every month dedicated to electrical and energy standards. See our CALENDAR for the next online meeting; open to everyone.
