GB/T 7403.1-2018Lead-acid traction batteries -- Part 1: Technical conditions (English PDF)

Foreword

GB/T 7403 "Leading Battery for Traction" is divided into two parts.

--- Part 1. Technical conditions;

--- Part 2. Product variety and specifications.

This part is the first part of GB/T 7403.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 7403.1-2008 "Leading Lead Acid Battery for Traction Part 1. Technical Conditions", and GB/T 7403.1-

Compared to.2008, the main technical changes are as follows.

--- Removed "capacity", "termination voltage", "charge retention capacity", "high rate discharge performance", "cycle durability", "charge and discharge cycle"

Terminology (see Chapter 3 of the.2008 edition);

--- Added the term "vented battery" (see 3.1.1);

--- Removed the relevant content of the battery "sealing agent" (see.2008 editions 4.5 and 6.6);

---Modified the "first capacity" technical indicators in the "capacity" clause (see 4.2.1);

--- Revised the technical indicators of "charge retention capacity" (see 4.3);

--- Revised the test method and technical indicators of battery cycle durability (see 4.5 and 6.5);

--- Added the relevant content of "Installation and Use Security Specification" (see Appendix A).

This part uses the redrafting method to modify the use of IEC 60254-1.2005 lead-acid batteries for traction - Part 1. General requirements and test

Method of inspection.

This section has more structural adjustments than IEC 60254-1.2005. This section and IEC 60254-1 are listed in Appendix A. 2005 chapter number comparison list.

There are technical differences between this part and IEC 60254-1.2005. Appendix B gives the corresponding technical differences and their causes.

Watch list.

This part was proposed by China Electrical Equipment Industry Association.

This part is under the jurisdiction of the National Lead-acid Battery Standardization Technical Committee (SAC/TC69).
