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).

organization of this document is not responsible for identifying patents.

GB/T 42284.4, as it takes much longer to reach the intended temperature in the
core of the component.
-- Mounting location in the vehicle
In current or future vehicle concepts, systems/components are mounted in almost
any location of the vehicle. The environmental requirements for each specific
application highly depend on its mounting location. Each location in a vehicle has
its distinct set of environmental loads. As an example, the range of temperatures
and vibration loads in the engine compartment differs significantly from that in
the passenger compartment. Body mounted components are typically exposed to
random vibrations whereas for engine mounted systems/components the
additional sine vibration from the engine is considered. Moreover, devices
installed in doors are exposed to a high number of mechanical shocks from door
slamming.
It is desirable for the vehicle manufacturer to group the different environmental load
types and levels in a reasonable number of standard requirement sets. This strategy
makes it possible to carry systems/components from one vehicle project to another.
Furthermore, the exact requirement levels are often unknown when designing a
component for a future vehicle concept. The expected environmental loads are usually
compiled from other vehicle concepts with similar conditions. The grouping is normally
done by mounting location, but it is difficult to...
