Scope
This document describes the test method for measuring energy consumption and driving range of fuel cell electric vehicles on a chassis dynamometer. This document applies to Class M and Class N fuel cell electric vehicles (hereinafter referred to as "vehicles") that use compressed gaseous hydrogen.
Introduction

1. Standard Overview

GB/T 43252-2023 "Test Method for Energy Consumption and Driving Range of Fuel Cell Electric Vehicles" is my country's first national standard for testing energy consumption and driving range of fuel cell electric vehicles. This standard is applicable to Class M and Class N fuel cell electric vehicles using compressed gaseous hydrogen, and specifies test conditions, measurement parameters and data processing requirements.


2. Standard Framework Comparison

Standard Dimensions GB/T 43252-2023 Comparative Analysis
Test Vehicle Classification Class A and Class B vehicles are determined according to formula (1). New classification methods are added to refine test requirements.
Measurement parameter requirements Cover key parameters such as distance, time, speed, and voltage. Parameter accuracy and resolution requirements are clear.
Test methods Two test procedures: shortened method and run-through method. Newly added hydrogen consumption measurement specifications, and detailed working condition cycle requirements.

3. Recommendations for standard implementation

3.1 Data acquisition and processing

In actual testing, data sampling and recording should be carried out in strict accordance with standard requirements. Pay special attention to the calibration of hydrogen mass flowmeter to ensure accurate measurement values. It is recommended to use professional software to automatically analyze test data to avoid manual calculation errors.

3.2 Test condition control

The laboratory ambient temperature should be strictly controlled within the range of (23±5)℃, and the vehicle immersion time should be no less than 2 hours. The resistance setting of the chassis dynamometer needs to select an appropriate standard curve based on the vehicle type and the maximum design gross mass.

3.3 Test mode selection

Class A vehicles use the shortened method test, and Class B vehicles can use the running method. For Class M and Class N vehicles, it is recommended to use the shortened method first to reduce the test time.

3.4 Data processing and analysis

Perform data processing according to the requirements of the standard appendix to ensure that the calculation of key indicators such as hydrogen consumption and driving range meets the formula requirements. Pay special attention to the proportional analysis of the fuel cell stack energy and the REESS energy to provide a basis for vehicle performance optimization.
