Preface 

This is the harmonized ANCE, CSA Group, and UL standard for DC Charging Equipment for Electric Vehicles . It is the first edition of NMX-J-817-ANCE, the first edition of CSA C22.2 No. 346, and the third edition of UL 2202. This edition of UL 2202 supersedes the previous edition(s) published on October 2, 2009, titled Electric Vehicle (EV) Charging System Equipment. This harmonized standard was prepared by the Association of Standardization and Certification, (ANCE), CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Electric Vehicle Supply Equipment of the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA) are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. The present Mexican standard was developed by the GT CONANCE from the Comite de Normalizacion de la Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaboration of different type of manufacturers and users. This standard was reviewed by the CSA Subcommittee on DC Fast Charging System for Electric Vehicles, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements on Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

1.1 These requirements apply to DC conductive charging equipment intended to be supplied with a maximum input voltage of 1000 V ac or 1500 V dc, for recharging the propulsion batteries in over-the-road electric vehicles (EV). DC charging equipment for EV installations are intended for either: a) Dry location only, or b) Dry, wet, and damp location. Equipment is intended to be installed in accordance with the Installation Codes in Annex A, Ref. No. 1. 

1.2 The output of the DC charging equipment for EV shall not exceed 1500 V dc. 

1.3 For the purposes of this Standard, the term "electric vehicle", designated throughout by the initials "EV", is considered to cover electric vehicles, hybrid electric vehicles, and plug-in versions of these vehicles. 

1.4 DC charging equipment for EV that is not a complete assembly and depends upon installation in an end product for compliance with the requirements in this Standard is investigated under the requirements of this Standard and the standard for the end product. 

1.5 These requirements do not cover battery chargers covered by Annex A, Ref. Nos. 2 and 3. 

1.6 These requirements do not cover on-board chargers. 

1.7 These requirements do not cover electric vehicle supply equipment covered by Annex A, Ref. No. 4. 

1.8 These requirements do not cover DC charging equipment for EV intended to be used in hazardous locations, such as near fuel dispensing stations.
