1 Scope
This document specifies the technical requirements and test methods for
conductive on-board chargers for electric vehicles.
This document applies to conductive on-board chargers for electric vehicles,
which have a nominal input voltage of 220 V (AC) (single-phase) or 380 V (AC)
(three-phase) AND an output voltage of not more than 1500 V (DC). Other types
of on-board charger may make reference to this standard.

through reference in this Standard. For the dated documents, only the versions
with the dates indicated are applicable to this document; for the undated
documents, only the latest version (including all the amendments) is applicable
to this standard.
