Foreword
This document is a standard or guiding technical document.
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents".
Drafting.
This document is modified to adopt IEC TS61430.1997 "Tests for performance verification of storage batteries and battery packs that reduce explosion hazard".
Method for starting with a lead-acid battery.
Compared with IEC TS61430.1997, this document has undergone many structural adjustments. A comparison of the structural numbering changes between the two documents is provided below.
See Appendix A for the table.
The technical differences between this document and IEC TS61430.1997, and the reasons therefor, are as follows.
---The scope of application has been changed (see Chapter 1) to suit my country's technological conditions;
---The description of the test method in the exhaust test (B.2.1) has been revised, and the precautions for testing different types of batteries have been improved;
---The constant voltage charging method in the exhaust test (see B.2.3) has been modified to conform to the current situation of the industry in my country.
The following editorial changes have been made to this document.
---To harmonize with existing standards, the standard title has been changed to "Lead-acid Batteries for Starting and Storage, and Battery Packs, with Reduced Explosion Hazards".
Test methods for device performance verification;
---IEC 60095-1.1988 (see 6.1.3) has been replaced by GB/T 5008.1-2023, which is cited in the informational reference.

Introduction
Starting lead-acid batteries contain dilute sulfuric acid. During use, especially during charging, the battery releases hydrogen, oxygen, or...
Hydrogen-oxygen mixture. When the hydrogen concentration reaches 4%~96% (volume fraction), if a hydrogen-air or hydrogen-oxygen mixture is ignited...
If it ignites, an explosion will occur. When this explosion happens inside the battery, the battery casing will rupture, and electrolytes and solid materials will be ejected.
come out.
Using an effective flame arrester in devices that reduce the risk of battery explosion will prevent external explosions from propagating into the battery.
No modifications are recommended to the battery's explosion hazard reduction devices, as these modifications may significantly affect the battery's protection.
Protection rating. If modifications or additions to the battery components are required, users should consult the battery manufacturer.
Lead-acid batteries for starting storage and battery packs
Test methods for performance verification of devices that reduce explosion hazard
1 Scope
This document describes the test methods for verifying a device (hereinafter referred to as the "device") used to reduce the explosion hazard of starting lead-acid batteries, and
Describe the protective measures that should be followed during the experiment.
This document applies to the performance testing of starting lead-acid batteries and battery packs that reduce the risk of explosion.
2 Normative references
This document has no normative references.
3 Terms and Definitions
This document does not contain any terms or definitions that need to be defined.
4.Protective Measures
4.1 Principles
When using or working near a storage battery, requirements 4.2 to 4.5 should be met.
4.2 Avoid short circuits
When using a storage battery, insulated tools should be used to avoid accidental short circuits. Before testing, all metal objects should be removed from the hands, wrists, and neck.
Ornaments.
4.3 Avoid static electricity
It is advisable to avoid static electricity, as this may cause the gas to ignite.
4.4 Circuit Connection and Disconnection
4.4.1 When the circuit may generate current or has already generated current, it is not advisable to connect or disconnect the battery.
4.4.2 When disconnecting the battery from the vehicle's electrical circuit, the terminal connected to the vehicle frame (ground) should be disconnected first; when connecting the circuit, the terminal connected to the vehicle frame (ground) should be connected last.
The terminal of the rack (grounding).
4.4.3 Smoking, open flames, or any source of sparks are strictly prohibited near the battery.
4.5 Charging Area
Charging should be done in a well-ventilated area.
Note. Some battery storage areas may have poor ventilation. Before testing, carefully disperse any explosive gases.
