[中文适用范围]： IEC PAS 61980-4:2025适用于通过磁场（MF-WPT）实现的高功率无线电力传输（H-WPT）的离板供电设备，用于为电动道路车辆的RESS（可充电储能系统）或其他车载电气系统供电，或两者同时供电。MF-WPT系统按照IEC 60038标准，其供电电压额定值可高达1000 V交流电和1500 V直流电。电力传输在电动汽车（EV）静止状态下进行。本文件涵盖的内容包括：– 特性及运行条件；– 针对电动道路车辆磁场高功率无线电力传输系统离板侧的特定电力传输要求；– 所需的电气安全等级；– 若磁场无线电力传输系统需要，针对安全和过程事项的基本通信要求；– 为确保高效且安全的磁场无线电力传输而要求的定位要求；– 磁场无线电力传输系统的特定电磁兼容性（EMC）要求。本文件不适用于：– 与维护相关的安全方面；– 无轨电车、铁路车辆及主要设计用于非道路使用的车辆。 [外文原描述]： IEC PAS 61980-4:2025 applies to the off-board supply equipment for high-power wireless power transfer (H-WPT) via magnetic field (MF-WPT) to electric road vehicles for purposes of supplying electric energy to the RESS (rechargeable energy storage system) or other on-board electrical systems, or both. The MF-WPT system operates at standard supply voltage ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC from the supply network. The power transfer takes place while the electric vehicle (EV) is stationary. The aspects covered in this document include – the characteristics and operating conditions, – specific power transfer requirements for the off-board side of magnetic field high-power wireless power transfer systems for electric road vehicles, – the required level of electrical safety, – requirements for basic communication for safety and process matters if required by a MF WPT system, – requirements for positioning to assure efficient and safe MF-WPT power transfer, and – specific EMC requirements for MF-WPT systems This document does not apply to – safety aspects related to maintenance, and – trolley buses, rail vehicles and vehicles designed primarily for use off-road
