GB 47371-2026Safety technical specification for electric bicycle charging piles (English PDF)

1 Scope

GB 47371-2026 is the Chinese national standard covering the public e-bike charging post - the output and its protection, the identification of the battery being charged, the detection of an abnormal charge, the fire separation and the enclosure, on equipment installed in courtyards and at the foot of apartment blocks. A mandatory standard, first edition, in force from 1 April 2027, and part of the same regulatory push as the charger standard GB/T 36944-2026 and the centralized facility series GB/T 42236. It was issued on 31 March 2026 and takes effect on 1 April 2027, as a first edition. The document is under the responsibility of the Ministry of Industry and Information Technology. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document defines the terms for electric bicycle charging piles (hereinafter referred to as "charging piles"), specifies the test conditions, general requirements, safety protection function requirements, and special requirements for DC charging piles, and describes the corresponding test methods. This document applies to AC/DC charging piles that charge electric bicycles and their batteries complying with GB 17761.

3 Terms and definitions

For the purpose of this document, the following terms and definitions apply.

3.1 electric bicycle A two-wheeled bicycle powered by an onboard battery, providing electric drive and/or electric assistance. [Source: GB 17761-2024, 3.1.1]

3.2 electric bicycle charging pile A power supply control device with output power on/off control, charging safety control, and human-machine interaction functions, used for the management and control of the charging process of electric bicycles and their batteries. NOTE. Electric bicycle charging piles are generally classified into AC charging piles and DC charging piles according to charging type. [Source: JB/T 14055-2022, 3.1, modified]

3.3 AC charging pile A facility consisting of an AC charging controller, power distribution lines, and sockets, capable of providing and managing 220 V AC power for charging electric bicycles and their batteries. [Source: GB/T 42236.1-2022, 3.4, modified]

3.4 DC charging pile A DC power supply device integrating DC output power on/off control and charging safety control functions. This device can directly provide a matching DC charging power supply to electric bicycles and their batteries. [Source: JB/T 14055-2022, 3.3, modified]

3.5 enclosure An enclosure that provides the appropriate type and degree of protection for its intended use.

3.6 maximum output current for a single port The maximum output current value for a single port of an electric bicycle charging pile as specified by the manufacturer.

4 Test conditions

4.1 Test environmental conditions Unless otherwise specified, the test is generally conducted under the following conditions.

a) ambient temperature. 25 °C ± 5 °C;

b) relative humidity. <= 75 %.

4.2 Parameter measurement tolerances Relative to specified or actual values, the accuracy of all control or measured values shall be within the following tolerance ranges.

a) voltage. ±0.5 %;

b) current. ±1 %;

c) temperature. ±2 °C.

5 General requirements

5.1 General rules Electric bicycle charging piles shall not pose a danger under normal use, reasonably foreseeable misuse, or malfunction conditions.

5.2 Basic requirements Unless otherwise specified, the basic safety requirements for charging piles shall comply with the provisions of GB 4943.1.

5.3 Safety-critical components Safety-critical components used in charging piles shall meet applicable safety protection requirements and be used within their rated values. Critical components such as wires, cables, sockets, and switches shall, as applicable, meet the safety-related requirements in the relevant national and industry standards listed in Table A.1 of Annex A. The safety-critical components used in charging piles and relevant standards, according to applicable conditions, include, but are not limited to, the categories listed in Table A.1.

13 Model specification code, assigned by the manufacturing enterprise. NOTE

2.The model specification code is not the model or specification of the charging pile, but rather a code assigned to model specifications by the manufacturing enterprise. Different model specifications of charging piles produced by the same manufacturing enterprise shall not use the same model specification code repeatedly. The model specification code can be numbers or English letters, but shall not use the letters I, O, or Z.

5.4.2 Marking durability The content indicated on the markings shall be clear, durable, and easily identifiable. All markings required in

5.4.1 shall be tested. During the test, wipe with a damp cotton cloth for 15 s, then wipe with a cotton cloth dampened with 75 % (volume fraction) alcohol for 15 s. After the test, the marking and warnings shall still be clear and legible, and shall not show any curling.

5.4.3 Instruction manual The instruction manual shall be provided with charging piles and shall include (but is not limited to) the following warning information.

a) Installation conditions; NOTE

1.Refer to Annex B for relevant content.

b) Charging operation procedure instructions after installation; NOTE

2.For example, including "connect the charger to the battery first, then connect to the charging pile," etc.

c) An air switch with leakage protection shall be provided during installation, and the equipment shall be reliably grounded;

d) Installation requirements related to safe use (including but not limited to. installation height, site selection requirements, wire diameter, wiring conduit requirements, etc.);
