Description
of content: IEC 61851-1:2017
applies to EV supply equipment for charging electric road vehicles, with a
rated supply voltage up to 1 000 V AC or up to 1 500 V DC and a rated output
voltage up to 1 000 V AC or up to 1 500 V DC. Electric road vehicles (EV)
cover all road vehicles, including plug-in hybrid road vehicles (PHEV), that
derive all or part of their energy from on-board rechargeable energy storage
systems (RESS). The aspects covered in this standard include:
- the
characteristics and operating conditions of the EV supply equipment;
- the
specification of the connection between the EV supply equipment and the EV;
- the
requirements for electrical safety for the EV supply equipment.
This third
edition cancels and replaces the second edition published in 2010. It
constitutes a technical revision.
This edition
includes the following significant technical changes with respect to the
previous edition:
a) The
contents of IEC 61851-1:2010 have been re-ordered. Numbering of clauses has
changed as new clauses were introduced and some contents moved for easy
reading. The following lines give an insight to the new ordering in addition
to the main technical changes.
b) All
requirements from IEC 61851-22 have been moved to this standard, as work on
IEC 61851-22 has ceased.
c) Any
requirements that concern EMC have been removed from the text and are
expected to be part of the future version of 61851-21-2.
d) Clause 4
contains the original text from IEC 61851-1:2010 and all general requirements
from Clause 6 of IEC 61851-1:2010.
e) Clause 5
has been introduced to provide classifications for EV supply equipment.
f) Previous
general requirements of Clause 6 have been integrated into Clause 4. Clause 6
contains all Mode descriptions and control requirements. Specific
requirements for the combined use of AC and DC on the same contacts are
included
