GB/T 18487.1 Charging Pile Testing

With the rapid development of the new energy vehicle (NEV) industry, the safety and reliability of charging piles and conductive charging systems for electric vehicles have become a central concern in the industry. On December 28, 2015, the Standardization Administration of China issued GB/T 18487.1-2015"Electric Vehicle Conductive Charging System - Part 1: General Requirements."However, due to the fast pace of technological progress in the EV sector, the 2015 version quickly became outdated. A new standard, GB/T 18487.1-2023, was released on September 7, 2023, and came into effect on April 1, 2024.

The new version builds upon the original standard while addressing various safety concerns observed in the market. It introduces updated provisions focused on safety and reliability, and fills gaps in standards related to high-power charging. This makes it a critical basis for the design, manufacturing, and testing of charging infrastructure.

As an authoritative third-party testing and certification body, China JJR Laboratory, accredited by CNAS, offers efficient and professional GB/T 18487.1 testing services.

Core Analysis of GB/T 18487.1 Standard

1. Scope of Application

This standard applies to:

AC charging piles(Mode 2 and Mode 3)

DC charging equipment(Mode 4)

It covers conductive charging systems between electric vehicles and power supply equipment, including:
