Radio Frequency Testing

Lithium batteries used in consumer electronics sold in China must comply with CCC (China Compulsory Certification) requirements. This guide covers the complete CCC certification pathway for batteries, including applicable standards, testing scope, and key steps for foreign and domestic manufacturers.

CCC Certification Scope for Batteries

Since August 2023, lithium-ion cells and battery packs have been formally included in the CCC mandatory certification catalog. This regulatory change significantly impacts battery manufacturers and importers selling in the Chinese market.

Products requiring CCC certification:

• Lithium-ion cells (cylindrical, prismatic, pouch) — CCC category 0915

• Lithium-ion battery packs — CCC category 0915

• Batteries embedded in CCC-certified end products (the end product certificate covers the battery)

Exemptions: Batteries for military, aerospace, and medical device applications follow separate regulatory pathways and are not covered by the CCC battery certification requirement.

Applicable Standards and Testing Requirements

Battery CCC certification follows the Chinese national standards adopted from IEC 62133 series:

GB 31241-2022　Lithium-ion cells and batteries used in portable electronic equipment — Safety requirements

GB/T 36276-2023　Lithium-ion cells and batteries for energy storage — Safety requirements

Key testing items under GB 31241-2022 for portable equipment batteries:

• Overcharge test — charging beyond upper limit voltage with 2x rated current

• External short circuit test — short circuit at 20°C±5°C and 55°C±5°C

• Thermal abuse test — 130°C±2K for 30 minutes

• Nail penetration test — φ3mm-φ7mm nail at 20mm/s-80mm/s speed

• Crush test — 13kN±0.78kN force applied

• Drop test — 1m free fall onto concrete surface

CCC Certification Process for Batteries

The battery CCC certification follows the standard type testing + factory inspection + post-certification surveillance model:

1. ①Application submission:Submit application to a CCC-designated certification body (CQC, CCIC, or others)

1. ②Document review:Submit product specifications, cell datasheets, BMS schematic, BOM, and production process documentation

1. ③Type testing:Send samples to a CCC-designated laboratory for full testing per GB 31241-2022

1. ④Factory inspection:Certification body conducts on-site inspection of production facility, quality system, and consistency controls

1. ⑤Certificate issuance:Upon successful testing and factory inspection, CCC certificate is issued

Total timeline is approximately 10-14 weeks, with type testing taking 6-8 weeks and factory inspection adding 2-4 weeks.

Factory Inspection Requirements and Preparation

CCC factory inspection for battery manufacturers focuses on production consistency and quality control:

• Incoming material inspection records for cells, BMS components, and packaging materials

• Production process control documentation and traceability system

• Routine testing records (100% routine tests per GB 31241 requirements)

• Calibration records for all testing equipment used in production and quality control

GTG Group provides comprehensive battery CCC certification services, from pre-testing through factory inspection preparation, helping manufacturers navigate the requirements efficiently.
