Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards 
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are 
described in the ISO/IEC Directives, Part  1 . In particular, the different approval criteria needed for the 
different types of ISO documents should be noted. This document was drafted in accordance with the 
editorial rules of the ISO/IEC Directives, Part  2 (see www.iso.org/directives ).
Attention is drawn to the possibility that some of the elements of this document may be the subject of 
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or 
on the ISO list of patent declarations received (see www.iso.org/patents ).
Any trade name used in this document is information given for the convenience of users and does not 
constitute an endorsement.

on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 18246:2015), which has been technically 
revised.
The main changes are as follows:
— t erms and definitions have been updated;
— r equirements for protection against electric shock ( Clause  7) have been rewritten;
— d escriptions for additional requirements and test procedure ( Clause  9) have been simplified;
— r equirements for the specific DC charging systems have been described in the Annexes (Annex  B for 
IEC 61851-25 and Annex  C for IEC TS 61851-3 series).

mopeds and motorcycles (referred to as the EVs) to external electric circuits.
NOTE  1 E xternal electric circuits include external electric power supplies and external electric loads.
It does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.
It applies only to on-board charging systems between the plug or vehicle inlet and RESS circuits.
NOTE  2 T he requirements when not connected to external electric circuits are specified in the ISO  1 3063 
series.
Requirements for bidirectional energy transfer DC to AC are under consideration and are not part of 
this document.
NOTE  3 T he safety requirements for DC EV supply equipment where protection relies on electrical separation 
are specified in IEC  61851-25.
NOTE  4 T he safety requirements for DC EV supply equipment where protection relies on double or reinforced 
insulation are specified in IEC TS 61851-3-1 and IEC TS 61851-3-2.

6.1 General
6.1.1  C onnections among charger, RESS, and vehicle
In the most fundamental sense of charging, there are three functional portions. The first is the supply 
network (mains). The second is the charger assembly that consists of charger and cable assembly. The third is the RESS, which may be incorporated onto the vehicle.
There are four ways in conductive charging systems regarding the connection to the earth by PE 
conductor. They are as follows.
a) C onnection to the earth: it consists of the charger assembly and the vehicle/RESS, both of them 
connected to the earth for fault protection. The requirements are specified in 6.1.3.2 .
b) N o connection to the earth: it consists of the charger assembly and the vehicle/RESS, neither of 
them connected to the earth. The requirements are specified in 6.1.3.3 .
c) S eparate connection to the earth: it consists of the charger assembly unconnected to the earth and 
the vehicle/RESS connected to the earth for fault protection. The requirements are specified in 6.1.3.4 .
d) P artial connection to the earth: it consists of the charger assembly connected to the earth for fault 
protection and the vehicle/RESS unconnected to the earth. The requirements are specified in 6.1.3.5 .
