Full Description

Preface

This is the first edition of CSA SPE-343, Electric vehicle energy management systems . This publication covers the design, manufacture, and testing of electrical equipment that comprises or forms a part of an electric vehicle energy management system. This SPE covers only the aspects of an electrical vehicle energy management system (EVEMS) which are not included in the other standards applicable to the equipment that comprise an EVEMS. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada. This publication was reviewed by the CSA Subcommittee on Electrical Vehicle Energy Management Systems, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety.

Scope

1.1 This publication applies to the design, construction, and testing of electrical equipment that comprises or forms part of an electric vehicle energy management system (EVEMS) (see Annexes A, B, C, D, and E) in accordance with the use of demand factor sub-rules of CSA C22.1, Canadian Electrical Code, Part I ("CEC Pt. I") or NFPA 70, National Electrical Code ("NEC") to reduce the calculated load contribution of electric vehicle supply equipment (EVSE) controlled by an EVEMS.

1.2 This publication applies only to the aspects of EVEMS equipment specific to them that ensure they can perform the required EVEMS functionality related to demand factor (see Annexes A and D). Equipment such as EVSE, that can optionally perform EVEMS functionality, requires listing to the EVSE standard(s) noted under Clause 2, as determined by the certification body and this publication. Equipment such as conduit, wire, cable, over-currents, current transformers, etc. do not require testing to this publication.

1.3 This publication applies to all aspects of controlling EVSE loads through the process of activating or suspending, increasing, or decreasing electric power to the electric vehicle supply equipment loads and/ or monitoring or calculating electric currents (power) loads in a consumer service, distribution equipment, feeders, or branch circuits.

1.4 This publication applies to the EVEMS equipment intended to be evaluated as a product that is configurable during and after installation, and which consists of any of the following: a) current (or power) monitoring device(s); b) communications equipment; c) controller(s); d) timer(s); e) compatible EVSE; and f) other applicable device(s). See the commentary in Annex A.

1.5 In this publication, "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 publication. 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. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
