VDE-AR-E 2623-2-2

IEC 62196 Plugs, socket-outlets, vehicle couplers and vehicle inlets – Conductive charging of electric vehicles is an international standard for a set of electrical connectors for electric vehicles and is maintained by the International Electrotechnical Commission (IEC).

The standard is based on IEC 61851 Electric vehicle conductive charging system which establishes general characteristics, including charging modes and connection configurations, and requirements for specific implementations (including safety requirements) of both electric vehicle (EV) and electric vehicle supply equipment (EVSE) in a charging system. For example, it specifies mechanisms such that, first, power is not supplied unless a vehicle is connected and, second, the vehicle is immobilized while still connected.

IEC 62196 comprises:

Every connector includes control signaling, not only allowing control of local charging, but allowing the EV to participate in a wider electric vehicle network. The signaling from SAE J1772 is incorporated in the standard for control purposes. All connectors can be converted with passive or simple adapters, although possibly not with all charging modes intact.

The following standards are incorporated as connector types:

The Framatome plug by EDF conforms to, but is not incorporated in, the standard.

IEC 62196-1 is applicable to plugs, socket-outlets, connectors, inlets and cable assemblies for electric vehicles, intended for use in conductive charging systems which incorporate control means, with a rated operating voltage not exceeding:

IEC 62196-1 refers to the charging modes defined in IEC 61851-1 which each specify required electrical characteristics, protections, and operation as follows:

This is a direct, passive connection of the EV to the AC mains, either 250 V 1-phase or 480 V 3-phase including earth, at a maximum current of 16 A. The connection does not have extra control pins. For electrical protection, the EVSE is required to provide earth to the EV (as above) and to have ground fault protection.

In some countries including the USA, Mode 1 charging is prohibited. One problem is that the required earthing is not present in all domestic installations. Mode 2 was developed as a workaround for this.

This is a direct, semi-active connection of the EV to the AC mains, either 250 V 1-phase or 400 V 3-phase including earth at a maximum current of 32 A. There is a direct, passive connection from the AC mains to the EV supply equipment (EVSE), which must be part of, or situated within 0.3 metres (1.0 ft) of, the AC mains plug; from the EVSE to the EV, there is an active connection, with the addition of the control pilot to the passive components. The EVSE provides protective earth presence detection and monitoring; ground fault, over-current, and over-temperature protection; and functional switching, depending on vehicle presence and charging power demand. Some protections must be provided by an SPR-PRCD conforming to IEC 62335 Circuit breakers - Switched protective earth portable residual current devices for class I and battery powered vehicle applications.
