Battery pack safety components (see 5.8);

e) Changes were made to the type testing and sample quantity (see Chapter 6, Chapter 3 of the 2011 edition);

f) Modifications were made to the test charging procedure (see 7.1, 4.1 of the 2011 version), the intended use (see 7.2, 4.2 of the 2011 version), and reasonable modifications.

Anticipated misuse (see 7.3, 4.3 in the 2011 edition), vibration adjustment (see 7.3.8.1, 4.2.2 in the 2011 edition), and mechanical shock.

h) Temperature cycling (see 4.2.4 in the 2011 edition) and low pressure (see 4.3.7 in the 2011 edition) have been removed;

i) Changes were made to the safety information (see Chapter 8, Chapter 5 of the 2011 edition), labeling (see Chapter 9, Chapter 6 of the 2011 edition), and packaging.

Transportation (see Chapter 10, Chapter 7 in the 2011 edition);

j) The safe charge/discharge range for lithium-ion batteries has been expanded (see Appendix A), and AC internal resistance measurement for coin cells has been added (see Appendix D);

k) This document incorporates relevant content from IEC 62133-2:2017/AMD1.2021.The main technical modifications include. 7.1.2 "separately stabilized" the phrase "1h and 4h" was changed to "stable for 1h to 4h", and "at the upper limit charging temperature" was deleted in 7.3.5b). The phrase "charging" was also deleted in 7.3.6a).

"Powered batteries must not cause fire or explosion if used beyond the time specified by the manufacturer." The battery testing ambient temperature in Table 5 has been changed.

Introduction

The.2011 edition of GB/T 28164 is equivalent to IEC 62133:2002.In.2017, IEC divided IEC 62133 into two parts. IEC IEC 62133-1:2017 (Safety requirements for nickel-based batteries) and IEC 62133-2:2017 (Safety requirements for lithium-based batteries). IEC GB/T 28164-2011 has significant technical differences compared to IEC 62133:2002, therefore revision of GB/T 28164-2011 is necessary.

Work. This revision adopts IEC 62133-2:2017 equivalently, partially replacing GB/T 28164-2011.

GB/T 28164 is proposed to consist of two parts.

---Part 1: Nickel-based batteries. This section aims to specify the safety requirements for nickel-based batteries and provide a standard basis for safety assessment of them.

---Part 2: Lithium-based batteries. This section aims to specify the safety requirements for lithium-based batteries and provide a standard basis for safety assessment of them.
