Full title and description

IEC/TS 62763:2013 — Pilot function through a control pilot circuit using PWM (pulse width modulation) and a control pilot wire. This Technical Specification defines the pilot (control pilot, CP) signalling method based on PWM and the electrical/functional parameters of the pilot conductor used for electric vehicle charging (Modes 2, 3 and 4) in the context of the IEC 61851 series.

Abstract

This Technical Specification specifies the control-pilot function implemented by a dedicated pilot conductor and PWM signalling for conductive EV charging. It gives parameter ranges, system states and transitions, test conditions and measurement points needed to ensure interoperable CP behaviour between EVs, cable assemblies and EV supply equipment in accordance with the IEC 61851 series requirements.

Scope

IEC/TS 62763:2013 applies to the pilot function implemented by a control pilot circuit using PWM and a dedicated pilot conductor for conductive charging of electric road vehicles. It covers the electrical parameters of the control pilot signal, defined system states and transitions, test procedures and measurement points for Mode 2, Mode 3 and Mode 4 charging as referenced in the IEC 61851 series. The TS was issued as an interim document to document PWM-based pilot behaviour pending revision of IEC 61851-1.

Key topics and requirements

• Definition of control pilot (CP) voltage levels and PWM duty-cycle semantics used to convey available current and system states.
• Specification of system states and allowed transitions for EV and EVSE behaviour during connection, charge initiation, charging and disconnection.
• Parameters and tolerances for CP waveform (frequency, voltage levels, duty-cycle interpretation) and measurement points for verification.
• Test procedures for normal charge cycles, CP state detection, PWM generation/interpretation, and interruption scenarios.
• Interoperability and interface requirements referencing the IEC 61851 series (Annex A of IEC 61851‑1 provides the normative control pilot description in later editions).
• Guidance on integration with proximity detection / cable current coding and protective functions required for safe charging.

Typical use and users

Intended readers include EVSE and vehicle charging-system designers, test laboratories, certification bodies, charging-station manufacturers, automotive OEMs and infrastructure integrators who implement or verify PWM-based control pilot signalling for conductive EV charging. The TS was used as a reference for developing and testing pilot-function implementations prior to inclusion of equivalent normative material in updated editions of IEC 61851-1.

Related standards

Primary related publications: the IEC 61851 series (especially IEC 61851-1) for conductive EV charging system definitions, interface modes and safety requirements. Other related documents include subsequent IEC/ISO deliverables that cover alternative CP communication methods (for example LIN on the pilot) and national adaptations of EVSE interfaces. The TS was intended to complement and be read alongside IEC 61851 parts and national regulations for EV charging.

FAQ

Q: What is this standard?

A: IEC/TS 62763:2013 is an IEC Technical Specification that defines the pilot (control pilot) function using PWM on a dedicated pilot conductor for conductive EV charging interfaces.

Q: What does it cover?

A: It covers PWM signal parameters, control-pilot voltage levels and tolerances, defined system states and transitions, test procedures and measurement points for Mode 2, Mode 3 and Mode 4 conductive charging as referenced by the IEC 61851 series.

Q: Who typically uses it?

A: EVSE manufacturers, vehicle charging-system designers, test laboratories, certification bodies, infrastructure integrators and OEMs involved with implementation and verification of pilot-signal behaviour.

Q: Is it current or superseded?

A: IEC/TS 62763:2013 was withdrawn (withdrawal date recorded as 13 February 2017). Its normative content on PWM-based pilot signalling has been incorporated or superseded by updates to the IEC 61851 series (see IEC 61851-1 Annex A in later editions) and other related IEC deliverables. Users should refer to the latest edition of IEC 61851-1 and any regional adaptations for current normative requirements.

Q: Is it part of a series?

A: It is a standalone Technical Specification published by TC 69 but explicitly intended to be read in the context of the IEC 61851 series (electric vehicle conductive charging). The TS served as an interim specification pending revisions of IEC 61851-1.

Q: What are the key keywords?

A: Control pilot, pilot conductor, PWM, duty cycle, EVSE, vehicle inlet, Mode 2, Mode 3, Mode 4, IEC 61851, interoperability, test procedures.
