1.1
This standard applies to electric vehicle energy management system(s) (EVEMS) product, sub-assemblies of matched assembly systems, and associated software, that provide functional safety control of electrical parameters intended to permit a demand factor to be applied to a calculated load for electric vehicle power transfer system equipment (EVPTSE), rated 1000 Volts ac or 1500 Volts dc or less, installed in accordance with the Canadian Electrical Code, Part I, CSA C22.1, and, the National Electrical Code, NFPA 70. An EVEMS may be equipped with other functionalities including non-safety control and communication.
1.2
The equipment to which the requirements of this standard apply is intended for use in indoor and outdoor nonhazardous locations.
1.3
This standard also includes a verification protocol, to validate the conditions listed in Electric Vehicle Energy Management Systems requirements of the Canadian Electrical Code, Part I, or the National Electrical Code are met, when EVEMS is implemented in accordance with the Electrical Code requirements for Canada and the USA. Refer to Section 0, Introduction.
1.4
The requirements of this standard do not apply to:
Equipment, sub-assemblies, or portions of software of EVEMS that do not perform load functional safety control if they are already covered by existing electrical equipment standards.
Electric Vehicle Supply Equipment (EVSE) contained in CSA C22.2 No. 280/UL 2594/NMX-J-677-ANCE (which does not contain EVEMS functionality)
Personnel Protection Systems for Electric Vehicle Supply Circuits as covered in CSA C22.2 No. 281.1/UL 2231-1 /NMX-J-668/1-ANCE and CSA C22.2 No. 281.2/UL 2231-2/NMX-J-668/2-ANCE.
Battery Chargers as covered by CSA C22.2 No. 346
Electric Vehicle Power Export Equipment (EVPE) equipment contained in CSA C22.2 No. 348/UL 9741 (which does not contain EVEMS functionality).
Wireless Power Transfer equipment contained in CSA C22.2 No. 61980-1 (which does not contain EVEMS functionality).
Wireless Power Transfer equipment is contained in UL 2750.
DC Charging Equipment for Electric Vehicles contained in ANCE NMX-J-817/CSA C22.2 No.346/UL2202 (which does not contain EVEMS functionality).
1.5
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
