GB/T 42284.1-2022Road vehicles - Environmental conditions and testing for electrical and electronic equipment for drive system of electric propulsion vehicles - Part 1: General (English PDF)

Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020,

Directives for standardization - Part 1.Rules for the structure and drafting of

standardizing documents.

This document is Part 1 of GB/T 42284 Road vehicles - Environmental conditions and

testing for electrical and electronic equipment for drive system of electric propulsion

vehicles. The following parts have been issued for GB/T 42284.

-- Part 1.General;

-- Part 3.Mechanical loads;

-- Part 4.Climatic loads;

-- Part 5.Chemical loads.

This document modifies and adopts ISO 19453-1.2018 Road vehicles - Environmental

conditions and testing for electrical and electronic equipment for drive system of

electric propulsion vehicles - Part 1.General.

The technical differences - between this document and ISO 19453-1.2018 - and the

reasons are as follows.

-- Remove the ISO and IEC database addresses for standardized maintenance terms,

since the terms involved in this document have nothing to do with the ISO and

IEC databases for standardized maintenance terms;

-- Replace ISO/PAS 19295 (see Clause 3) with the normative reference ISO 21498-

1, and ISO/PAS 19295 with ISO 21498-1;

-- Replace ISO 6469-3 (see 6.1) with the normative reference GB 18384, between

which there is no consistent correspondence (see 6.1);

-- Replace ISO 16750-1 (see Clause 3) with the normative reference GB/T 28046.1,

between which the degree of consistency is modification, to adapt to the technical

conditions in China and improve operability;

-- Replace ISO 20653 (see 8.1) with the normative reference GB/T 30038, between

which the degree of consistency is modification, to adapt to the technical

conditions in China and improve operability;

-- Replace ISO 19453-3 (see 7.1, 8.1, 8.2) with the normative reference GB/T

42284.3, between which the degree of consistency is modification, to adapt to the

technical conditions in China and improve operability;

-- Replace ISO 19453-4 (see 7.1, 8.1, 8.2) with the normative reference GB/T

42284.4, between which the degree of consistency is modification, to adapt to the

technical conditions in China and improve operability;

-- Replace ISO 19453-5 (see 7.1, 8.1, 8.2) with the normative reference GB/T

42284.5, between which the degree of consistency is modification, to adapt to the

technical conditions in China and improve operability;

-- Adjust the range of voltage class A and voltage class B, and adjust the definition

of electric propulsion system and electric propulsion vehicle, so as to adapt to the

technical conditions in China;

-- Delete the definition of customer and supplier;

-- Add "control in typical operating mode" in operating mode 3.2, to clarify the

requirements of the operating mode 3.2 (see 5.3);

-- In 6.2, add the test to only examine the function when it is in the active operating

mode, to be consistent with the requirements of other parts of the document.

The following editorial changes have been made for this document.

-- Add the note "The load that is turned on in the typical operating mode can be

determined through negotiation between the customer and the supplier" below

the operating mode 2.2, operating mode 3.2, and operating mode 4.2, to make the

typical operating mode easier to understand (see 5.2, 5.3, 5.4).

1 Scope

This document specifies requirements for the electric propulsion systems and

components with maximum working voltages according to voltage class B. This

document describes the potential environmental stresses and specifies requirements

recommended for different stress levels on/in the vehicle. This document contains

definitions, mounting location, operating mode and other general requirements.

2 Normative references

The following documents are referred to in the text in such a way that some or all of

their content constitutes requirements of this document. For dated references, only the

version corresponding to that date is applicable to this document; for undated references,

the latest version (including all amendments) is applicable to this document.

GB 18384, Electric vehicles safety requirements

3 Terms and definitions

Terms and definitions determined by GB/T 28046.1 and ISO 21498-1, as well as the

following ones, are applicable to this document.

A general term for battery electric vehicles, hybrid electric vehicles, and fuel cell

electric vehicles.

4 Classification by mounting location

For some locations with special environmental conditions (e.g., exhaust system), no

standard specifications can be given. In these cases, it shall be stated in the specification

of the DUT.

5 Operating modes

The DUT is electrically operated with a test voltage UB as in a vehicle with shut-off

combustion engine, high voltage battery (DC/DC) disconnected and all electrical

connections made.

The DUT is electrically operated with test voltages UA and UX with all electrical

connections made.

6 Functional status classification

All functions of the device/system perform as designed during and after the test.

One or more functions of a device/system do not perform as designed during the test,

but automatically return to normal operation after the test.

7 Tests and requirements

Unless otherwise specified, all tests shall be performed at a room temperature (RT) of

23 °C +/- 5 °C and a relative humidity of 25% ~ 75%.

A life test shall be defined specifically for the product and be taken into account in the

test sequence plan.
