Drafting.

This document is Part 3 of GB/T 41134 "Fuel Cell Power Generation Systems for Electric Driven Industrial Vehicles". GB/T 41134 has been issued.

The following parts were laid out.

---Part 1: Security;

---Part 2: Performance Test Methods;

---Part 3: Performance test methods for fuel cell/battery hybrid systems for excavators.

This document is modified to adopt IEC 62282-4-600:2022 "Fuel cell technology – Part 4-600.Fuel cell systems, except for road vehicles and auxiliary power units".

Performance test method for fuel cell/battery hybrid power generation system for excavators other than fuel cell power generation system (APU).

Compared with IEC 62282-4-600:2022, this document has undergone the following structural adjustments.

---Adjusting the abbreviations in section 3.2 of IEC 62282-4-600:2022 to Chapter 4, merging them with the original Chapter 4 of the international standard into "Symbols and Symbols".

"Abbreviations". (See 3.2 of IEC 62282-4-600:2022, and Chapter 4 of this document);

---Removed sections 9.1 to 9.4 from Chapter 9 of IEC 62282-4-600:2022 (see sections 9.1 to 9.4 in IEC 62282-4-600:2022);

---Reference standards for fuel molar mass measurement (section 13.2.1.3.2) and fuel calorific value (section 13.2.2.3) have been removed from IEC 62282-4-600:2022.

Measurement reference standard;

---Adjustments to International Standard 3.1 Terms and Definitions are made to Chapter 3;

The technical differences between this document and IEC 62282-4-600:2022, and the reasons therefor, are as follows.

---The scope of "liquid hydrogen" in IEC 62282-4-600:2022 has been removed (see Chapter 1) to facilitate the use of the standard;

--- Added normative reference to GB/T 14412-2005 (see 15.5.1) for ease of use of the standard;

---The abbreviations "BMS, FID, EMS, FMS" in Chapter 4 of IEC 62282-4-600:2022 have been removed (see section 4.1 of this document);

---The configuration and structure of the fuel cell/battery hybrid system (see Figures 2 and 3) have been modified to facilitate standardization.

Approved for use;

---The overview, measuring instruments, measuring points, and minimum measurement parameters of Chapter 9 "Instruments and Methods of Measurement" in IEC 62282-4-600:2022 have been removed.

The measurement system uncertainty should be replaced with "the minimum requirement for the measurement system uncertainty" (see IEC 62282-4-600:2022, section 9.1~).

9.4 (see Chapter 9) to facilitate the use of the standard;

---Some test duration options have been modified (see 13.2.1.5, 13.3.2, 13.4.1.2, 13.4.3.3, Table A.1) to facilitate standardization.

use;

---Added simulation condition testing requirements and recommendations (see 15.5.1) to facilitate the use of the standard.

The following editorial changes have been made to this document.

---The standard title has been changed to "Fuel Cell Power Generation Systems for Electric Industrial Vehicles - Part 3: Fuel Cells/Battery Hybrids for Excavators" "System Performance Test Method";

---The error was corrected; 0.5 in the acceleration spectral density diagram of the random vibration test should be 0.05.
