GB/T 18487.4-2025 Electric vehicle conductive charging and discharging system—Part 4:Discharging requirements for electric vehicle
Basic Information
Scope
This document specifies the classification of electric vehicle conductive discharge systems, general requirements, communication, connection components, and power consumption requirements, as well as safety requirements for discharging vehicles, environmental requirements, and marking and instructions. This document applies to electric vehicles that can discharge electricity to the outside of the vehicle through a vehicle interface, with an AC discharge rated output voltage not exceeding 250 V for a single phase or 440 V for a three-phase system, and a DC discharge output voltage not exceeding 1,000 V. This document only applies to M1-class electric vehicles. This document does not apply to discharging through discharge interfaces inside the vehicle, such as through cigarette lighters, USB interfaces, or sockets that comply with GB/T 1002. This document does not apply to power supplies for special electrical equipment such as medical devices.
