IEC/TS 62763:2013（E）描述了导频线功能，该功能被设计为向电动车辆提供电能的控制机制，主要用于为车辆的牵引蓄电池充电。它涉及所有充电系统，这些系统通过一个带PWM的导频线电路来确保模式2、模式3和模式4充电的导频功能，如IEC 61851系列所述。

IEC/TS 62763:2013(E) 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.
