ANSI/CAN/UL 2278:2025

Scope 1.1 These requirements cover vehicle connectors and vehicle inlets designated as, and configured as, megawatt charging couplers. These devices are rated up to 1500 Vdc, 3000 A under conditions of continuous use. Vehicle connectors and vehicle inlets may be provided with thermal sensing on contacts or they may be actively cooled, such as with liquid cooling, when operating. These devices are intended for use with conductive DC charging equipment for electric vehicles and intended to facilitate conductive connection from the charging equipment to the vehicle. These devices are for use in either indoor or outdoor, non-classified locations in accordance with National Electrical Code (NEC), NFPA 70 and the Canadian Electrical Code (CE Code), CSA C22.1. 1.2 This Standard does not apply to any device that is not intended for use as described in 1.1. 1.3 This Standard does not cover devices used for conductive connection to an electric vehicle and consisting of configurations other than megawatt charging systems configurations. Those devices are covered by the Standard for Plugs, Receptacles and Couplers for Electric Vehicles, UL 2251, or CSA C22.2 No. 282. 1.4 This Standard is intended to be used in conjunction with the Standard for Plugs, Receptacles and Couplers for Electric Vehicles, UL 2251, or CSA C22.2 No. 282 and will indicate where requirements are different.
