To meet the growing certification demands in the energy storage sector, GTG Group – Guangdong ESTL Technology Co., Ltd. (hereinafter referred to as "ESTL") has successfully expanded its CQC (China Quality Certification Center) certification qualifications, adding authoritative certification capabilities for two key standards:

• GB 40165-2021: Lithium-Ion Batteries and Battery Packs for Fixed Electronic Equipment
• SJ/T 11778-2021: Lithium-Ion Batteries and Battery Packs for Portable Household Appliances
   

1. Newly Added CQC-Certified Standards: Scope & Sample Requirements

1.1 GB 40165-2021: Lithium-Ion Batteries for Fixed Electronic Equipment

As a highly normative industry standard, GB 40165-2021 specifies safety technical requirements and test methods for lithium-ion batteries and battery packs used in fixed electronic equipment, ensuring product quality and operational safety.

Scope of Application

The standard covers a wide range of fixed electronic equipment and high-precision devices, including:

• Fixed information technology (IT) equipment;
• Fixed audio/video (AV) equipment and similar devices;
• Fixed communication technology (CT) equipment;
• Fixed measurement, control, and laboratory electronic equipment;
• Batteries and battery packs for high-end devices such as UPS (Uninterruptible Power Supply) and EPS (Emergency Power Supply).

Sample Requirements

• Representativeness: Samples must be representative of products intended for market delivery (e.g., small-batch trial production samples or products ready for shipment) to ensure highly reliable test data.
• Wire Resistance: If test wires or connections are required for the test, the total resistance from such wires/connections must be ≤ 30 mΩ.
• Quantity: 3 battery samples and 1 battery pack sample per test item.

1.2 SJ/T 11778-2021: Lithium-Ion Batteries for Portable Household Appliances

SJ/T 11778-2021 is a critical safety technical specification for lithium-ion batteries and battery packs used in portable household appliances, covering diverse portable devices across multiple categories.

Scope of Application

The standard applies to a broad range of portable household appliances, including:

• Personal cleaning & care appliances: Electric toothbrushes, shavers, hair clippers, exfoliators, etc.;
• Personal health appliances: Cervical/lumbar massagers, electric heating knee pads, hand warmers, etc.;
• Site cleaning appliances: Robot vacuum cleaners, mopping machines, vacuum cleaners, window cleaners, electric irons, garment steamers, etc.;
• Other smart appliances: Lighting fixtures, air purifiers, humidifiers, indoor environment monitors, etc.

Note: For portable appliances used in specific scenarios (e.g., RVs, cruise ships, aircraft), additional requirements must be met.

Sample Requirements

• Freshness & Representativeness: Samples must be new products manufactured within 6 months and highly representative to ensure authentic and accurate test results.
• Wire Resistance: If test wires or connections are required for the test, the total resistance from such wires/connections must be 40–80 mΩ.
• Quantity: 3 samples per test item.

2. Significance of the New CQC Qualifications

The addition of these two CQC certification capabilities fully reflects CQC’s high recognition of GTG ESTL’s laboratory technical strength and service capabilities. Through extensive project practice, GTG ESTL’s technical team has mastered the key points of CQC certification for lithium-ion batteries in fixed electronic equipment and portable household appliances.
