a) Major changes are required to meet the requirements of national standard inspection items;
b) The effectiveness of steering and braking systems cannot ensure driving safety;
c) There is a big gap between test vehicle performance indicators and
product technical conditions;
d) The frame, body and its load-bearing system are broken or cracked, and the test cannot be carried out;
e) The fuel cell system, battery system, motor and its control system, DC/DC converter, on-board hydrogen system, on-board charging system have
serious problems or frequent problems that cannot be tested;
f) Other circumstances that the testing organization considers that the test shall be terminated.
4.5 During the test, the operation shall be carried out according to the provisions of the instruction manual. Maintenance shall be performed.
4.6 After the test is completed, the testing organization will provide a test report according to the provisions of Clause 6 and Clause 7.
5 Test items, test methods and judgment basis
5.1 General rules
5.1.1 The test vehicle shall be subjected to three tests: compulsory national standards and related regulations inspection, whole-vehicle performance test and whole-vehicle reliability driving test.
5.1.2 The test items of the modified vehicles shall be determined according to the specific changes. All items that change due to the modification shall be tested (inspected).
5.2 Compulsory national standards and related regulations inspection
5.2.1 Overview
Vehicles shall meet the requirements of relevant mandatory national standards and related regulations. See 5.2.2~5.2.4 for the three test methods of external noise, hydrogenation port, and vehicle hydrogen system.
5.2.2 Test of external noise
a test site authorized by the state.
5.4.2 The total mileage of the reliability driving test is 15000km. Test in the hybrid drive mode. For the vehicle of which the total mass is not greater than 3500kg, the mileage is allocated as follows: strengthened bad road -- 3000km, flat road -- 2000km, high-speed runway -- 5000km, durable working condition - - 5000km (in accordance with Annex B of GB/T 19750-2005). For the vehicle of which the total mass is greater than 3500kg, the mileage is allocated as follows: strengthened bad road -- 3000km, flat road -- 2000km, high-speed runway -- 5000km, durable working condition -- 5000km (in accordance with Annex A of GB 20890-2007).
5.4.3 The main assembly shall not have types 1, 2 failures during the test. After the test, the insulation performance, hydrogen leakage and idling exhaust emissions of the vehicle shall meet the requirements of GB/T 24549.
NOTE 1: Type 1 failure refers to a failure that has occurred or will have a destructive situation, which leads to the loss of system functions and may cause personal danger or the main assembly of the vehicle to be scrapped; it needs to take emergency stop and issue warning measures. Type 2 failure refers to a failure that seriously degrades the performance of the system or damages the main assembly and cannot continue to operate but does not constitute a personal danger; it may take normal shutdown and issue warning measures.
6 Test procedures
6.1 Receive and check the test sample vehicle. Register it.
6.2 Conduct run-in driving in accordance with the manufacturer's regulations. 6.3 Carry out the tests such as compulsory national standards and related regulations inspection, whole-vehicle performance test, reliability driving test, and whole-vehicle performance retest.
7 Test report
The test report shall contain the following information:
a) Task source;
b) Test purpose;
c) Basis for determining the test plan;
d) Main standards for test basis;
Annex A
(informative)
Test method for driving range
A.1 Test conditions
A.1.1 Conduct the indoor test at room temperature of 20??C~30??C.
A.1.2 The viscosity of lubricating oil for mechanical moving parts meets the manufacturer's regulations.
A.1.3 Turn off the lighting, signal devices and auxiliary equipment on the vehicle, unless these devices are required for testing and daytime operation of the vehicle.
A.1.4 Except for driving purposes, all energy storage systems are charged to the maximum value specified by the manufacturer (electricity, hydraulic pressure, air pressure).
A.1.5 The test driver makes the fuel cell and power battery work at normal operating temperature in accordance with the operating procedures
recommended by the vehicle manufacturer.
A.1.6 The test vehicle shall be run-in according to the manufacturer's
specifications. The running-in mileage is not less than 300km.
A.1.7 For M1 and N1 vehicles as well as M2 vehicles of which the total mass does not exceed 3500kg, chassis dynamometer settings are carried out in accordance with Annex CC of GB 18352.6-2016.
