IEC/TS 62763-2013 pdf free.Pilot function through a control pilot circuit using PWM (pulse width modulation) and a control pilot wire.
This Technical Specification describes the pilot wire function designed as a control mechanism for the supply of electrical energy to electric vehicles, principally for the charging of the traction batteries of the vehicle. It concerns all charging systems that ensure the pilot function with a pilot wire circuit with PWM for mode 2, mode 3 and mode 4 charging as described in the IEC 61851 series.
This document describes the functions and sequencing of events for this circuit based on the recommended typical implementation circuit parameters. The parameters indicated also ensure the interoperability of control pilot wire systems designed according to SAE J1772.
This document is not applicable to vehicles using pilot functions that are not based on a PWM signal and a pilot wire.
NOTE 1 In the context of this document the words EV supply equipment’ designate any one of the following: the AC EV supply equipment in mode 3. the in cable control box in mode 2 and/or the DC EV supply equipment in mode 4.
NOTE 2 The control pilot wire is a supplementary conductor, in addition to the power lines linking the vehicle to EV supply equipment via the vehicle coupler.

3 Control pilot circuit
3.1 General
Two types of pilot functions are possible: simplified and typical.
● Simplified pilot function fulfils the basic requirements that are described in 6.4.1 of IEC 61851-1:2010.
● Typical pilot function fulfils the basic requirements that are described in 6.4.1 of IEC 61851-1:2010 and also allows the selection of charging rate as described in 6.4.2. of IEC 61851-1:2010.
Additional requirements for implementation in mode 4 system are described in IEC 61851-23.
Figures 1 and 2 show examples of the principle of operation of the control pilot circuit.
The EV (electric vehicle) supply equipment may cut off the power after at least 5 s in case the EV will use more current than the duty cycle indicates.
It is recommended to de-energize the system, if the measured current exceeds the current signalled by duty cycle with a tolerance of 10 %.
[RA03-010] The circuit parameters shall be designed in accordance with Table 2, Table 3 and 3.4.
[RA03-020] The functionality of the pilot line shall follow the requirements defined in Table 2, Table 6, Table 7, and Table 8.
