GB/T 43191-2023On-site testing instruments of AC charging spot for electric vehicles (English PDF)

Foreword

This document was issued on 7 September 2023 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 April 2024.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 43191-2023 specifies the instruments used to test AC charging points for electric vehicles in the field. A charge point is a metering device sold to the public: it bills by the kilowatt hour, so it falls under legal metrology, and it must be verified where it stands rather than in a laboratory - outdoors, on a live supply, by a technician with a portable instrument. That instrument must therefore be accurate enough to judge the meter, safe on an unknown installation, and able to emulate the vehicle's control pilot signalling well enough to make the charger operate. The standard sets the technical requirements - working environment, mechanical, electrical, electromagnetic compatibility, measurement performance and interfaces - and the corresponding test methods, followed by the inspection rules and the marking, packaging, transport and storage provisions. It took effect on 1 April 2024.

This document defines the terms and definitions of on-site testing instruments of AC

charging spot for electric vehicles, stipulates the technical requirements for mechanical

properties, electrical properties, electromagnetic compatibility, measurement

performance, interfaces, etc., describes the corresponding test methods, inspection rules,

and specifies aspects such as marking, packaging, transportation and storage.

This document applies to the design, manufacturing, procurement and acceptance of

on-site testing instruments of AC charging spot for electric vehicles.

17215.231-2021.

4.2.6.2 Transportation protection

The enclosure of the testing instrument shall comply with the provisions of 7.3 in GB/T

17215.231-2021.

4.3 Electrical performance

4.3.1 Power supply

The testing instrument shall at least meet the requirements of 4.5 when working under

the following AC power supply conditions:

a) Rated voltage: single-phase 220 V, allowable deviation: -20% ~ +15%;

b) Frequency: 50 Hz, allowable deviation +/-1 Hz;

c) Waveform: sine, waveform distortion factor <=5%.

For the testing instrument using built-in battery power, a fully charged built-in battery

shall be able to operate continuously for at least 4 hours.

4.3.2 Power consumption

When the auxiliary device of the testing instrument is not working, the power

consumption of the entire testing instrument shall not exceed 50 W.

4.3.3 Insulation resistance

the non-electrically connected live circuits of the testing instrument and between each

4.6.4 Load communication interface

For testing instruments with load communication interfaces, the manufacturing unit

shall provide the communication protocol between the testing instrument and the load.

The communication protocol should be made by referring to Appendix B.

4.6.5 Auxiliary interface

The testing instrument should have charging connection confirmation (CC), control

pilot (CP) signal lead-out interface and AC power supply (L1, L2, L3, N) lead-out

interfaces. The corresponding signal ports between the lead-out interfaces and the

charging interface shall be reliably electrically connected, and the AC power outlet

interface shall be protected against accidental collision.

4.6.6 Corrosion and rust resistance
