61 FOREWORD

62 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

63 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

64 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

65 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

66 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

67 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

68 in the subject dealt with may participate in this preparatory work. International, governmental and non-

69 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

70 with the International Organization for Standardization (ISO) in accordance with conditions determined by

71 agreement between the two organizations.

72 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

73 consensus of opinion on the relevant subjects since each technical committee has representation from all

74 interested IEC National Committees.

75 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

76 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

77 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

78 misinterpretation by any end user.

79 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

80 transparently to the maximum extent possible in their national and regional publications. Any divergence

81 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

82 the latter.

83 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

84 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

85 services carried out by independent certification bodies.

86 6) All users should ensure that they have the latest edition of this publication.

87 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

88 members of its technical committees and IEC National Committees for any personal injury, property damage or

89 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

90 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

91 Publications.

92 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

93 indispensable for the correct application of this publication.

94 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

95 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

96 This amendment of International Standard IEC 62196-3 has been prepared by subcommittee

97 23H: Plugs, socket-outlets and couplers foe industrial and similar applications, and for electric

98 vehicles, of IEC technical committee 23: Electrical accessories.

99 This fourth edition cancels and replaces the third edition published in 2014 and constitutes a

100 technical revision, with the following significant technical changes with respect to the previous

101 edition:
102 a) Increased ratings for all configurations.
103 b) Reference to new tests in Part 1 (clauses 34, 35, 36 and 37)

113 This document is to be read in conjunction with IEC 62196-1. The clauses of the particular

114 requirements in Part 3 supplement or modify the corresponding clauses in Part 1. Where the

115 text indicates an "addition" to or a "replacement" of the relevant requirement, test specification

116 or explanation of Part 1, these changes are made to the relevant text of Part 1, which then

117 becomes part of the standard.

134 INTRODUCTION
135 IEC 61851 series specifies requirements for EV conductive supply equipment.

136 IEC 62196 series specifies the requirements for plugs, socket-outlets, vehicle connectors,

137 vehicle inlets and cable assemblies as described in the IEC 61851 family of standards.

138 Charging using off-board DC charging equipment can be achieved by the direct connection of

139 an electric vehicle to DC EV supply equipment incorporating control and communication

140 circuits.

141 To support the connection of DC power for such vehicles, this standard provides the standard

142 interface configurations of DC vehicle couplers and accessories to be used in conductive

143 charging of electric vehicles, taking the most frequent charging situations into consideration.

144 IEC 62196 is divided into several parts as follows:
145 – Part 1: General requirements, comprising clauses of a general character.

146 – Part 2: Dimensional compatibility requirements for AC pin and contact-tube accessories.

147 – Part 3: Dimensional compatibility requirements for DC and AC/DC pin and contact-tube

148 vehicle couplers.

149 – Part 4 : Dimensional compatibility requirements for DC pin and contact-tube accessories

150 for Class II or Class III applications.

151 – Part 6 : Dimensional compatibility requirements for DC pin and contact-tube couplers for

152 applications using a system of protective electrical separation.
