Draft Details

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). Equipment is intended to be installed in accordance with the Installation Codes in Annex A, Ref. No. 1. DC charging equipment, either standalone chargers or dispensers, with internal batteries exceeding 100 Wh and less than 20kWh serving as energy storage also is intended to be installed in accordance with the installation requirements in Annex A, Ref. No. AA. DC charging equipment with separable enclosures with internal batteries not in a standalone charger or charging dispenser shall be dual listed with the enclosures containing internal batteries also listed under UL 9540. DC charging equipment for EV installations are intended for either:

a) Dry location only, or

b) Dry, wet, and damp location.

1.2 The output of the DC charging equipment for EV covered by this standard does 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.

1.9 These requirements do not apply to cover bi-directional charging equipment, or unidirectional power export equipment, covered by Annex A, Ref. No. 73B.
