With the rapid development and widespread application of battery technology, China’s safety supervision over various battery products has become increasingly refined. Recently, the state has intensively issued a series of new national standards and certification requirements for battery products, covering key areas such as power banks, electric bicycle batteries, and power batteries for electric vehicles. Statistics show that the newly implemented battery standards and certification rules in 2025 will affect over 80% of battery manufacturers, exerting a profound impact on product design, production processes, and market access.

I. New Certification Rules for Power Banks & Lithium-Ion Batteries

1. Overview of New Rules

The Rules for the Implementation of Compulsory Product Certification – Power Banks, Lithium-Ion Batteries and Battery Packs (Trial) (CNCA-C09-02:2025), released via Announcement No. 15 of 2025 by the Certification and Accreditation Administration of China (CNCA), has officially replaced the former Rules for the Implementation of Compulsory Product Certification – Electronic Products and Safety Accessories (CNCA-C09-01:2023) since August 15, 2025. This marks a new phase in the CCC certification management of power banks and lithium-ion batteries.

2. Key Changes

Adjusted Certification Model

• Unified into a three-in-one model: "Type Test + Initial Factory Inspection + Post-Certification Supervision".

Revised Sampling Method

• Abolished enterprise self-sampling; instead, certification bodies or laboratories conduct random on-site sampling from production lines or finished product warehouses.
• When the sampling base is ≥300 units, 3-5 samples are randomly selected.
• A case study: An enterprise failed certification due to an 8% internal resistance deviation between mass-produced batteries and tested samples, highlighting the criticality of product consistency.

Strengthened Process Control

• Complete video recording is mandatory during sampling and testing; test samples must be properly preserved for future inspection.
• Clear requirements for monitoring key processes, such as charge-discharge testing and welding process documentation.

Upgraded Factory Inspections

• Added explicit requirements for key production processes of enterprises, covering "every critical link from raw materials to finished product delivery".
• Frequency of post-certification supervision varies by enterprise classification: once a year for Class A enterprises (with good quality reputation), and higher frequency for other categories.

3. Transition Period Arrangements

• Valid CCC certificates issued before the new rules can continue to be used, with natural transition through methods such as certificate renewal upon expiration, product modification, or standard version update.
• For certified products, certification bodies will verify compliance with new rules during annual supervision inspections.

II. New Certification Rules for Lithium-Ion Batteries for Electric Bicycles

1. Implementation Timelines

• November 1, 2025: Lithium-ion batteries and chargers for electric bicycles must obtain CCC certification and be marked with the CCC logo before leaving the factory, being sold, imported, or used in business activities.
• December 1, 2025: Electric bicycles that do not meet new national standard requirements or lack CCC certification will be prohibited from sale.
• September 1, 2025: The new national standard Safety Technical Specifications for Electric Bicycles (GB 17761-2024) has been officially implemented; complete electric bicycles must comply with the new requirements and obtain CCC certification.

2. Transition Between Old and New Standards

• All valid CCC certificates issued based on old standards will be revoked by designated electric bicycle certification bodies by December 1, 2025.
• Separate certification is required for complete electric bicycles, lithium-ion batteries for electric bicycles, and chargers—no bundling relationship exists.

3. New Technical Requirements

Adjusted Vehicle Weight

• For electric bicycles using lead-acid batteries: Maximum vehicle weight increased from 55kg to 63kg.
• For electric bicycles using other types of batteries (mainly lithium batteries): Maximum vehicle weight remains ≤55kg.

Enhanced Fire and Flame Retardancy

• The total plastic weight of electric bicycles shall not exceed 5.5% of the total vehicle weight, with strengthened fire and flame retardancy requirements for non-metallic materials.

Upgraded Tamper-Proof Design

Labeling and Coding

• Clarified the requirement of "one vehicle, one battery, one charger, one code" and mutual recognition coordination to realize full-life-cycle traceability of products.

III. New National Standard for Power Batteries for Electric Vehicles

1. Implementation Time

The Safety Requirements for Power Batteries for Electric Vehicles (GB 38031-2025), released on March 28, 2025, will be officially implemented on July 1, 2026, with differentiated transition periods for different vehicle types:

• New models applying for type approval: Implementation starts on July 1, 2026.
• Models already approved for type: Implementation starts on July 1, 2027.

2. Key Technical Updates

Upgraded Thermal Propagation Test

• Revised from "providing a thermal event alarm signal 5 minutes before ignition or explosion" to "no ignition, no explosion (alarm still required), and flue gas shall not harm occupants".
• This change is known as the "strictest ever" safety requirement in the industry, which will significantly reduce the risk of power battery spontaneous combustion.

New Bottom Impact Test

• Simulates scenarios where foreign objects (e.g., flying stones, ground obstacles) impact the battery pack from below. A 30mm-diameter impactor applies a vertical upward impact energy of 150J to the battery pack bottom.
• Requirements after testing: No ignition, no explosion, no leakage, no rupture, and compliance with insulation resistance standards.

New Safety Test After Fast Charging Cycles

• For ultra-fast charging technology that can charge the battery from 20% to 80% in 15 minutes, an external short-circuit test is required after 300 fast charging cycles (SOC range: 20%-80%).
• Requirements after testing: No ignition, no explosion, ensuring safety in high-frequency fast charging scenarios.

IV. Guide to Battery New National Standard Certification Process

1. List of Certification Preparation Materials

2. Detailed Basic Certification Process

Step 1: Application Acceptance

• Submit applications to CNCA-designated certification bodies (e.g., CQC China Quality Certification Center).
• After acceptance, the certification body issues a notice requesting the enterprise to submit complete technical documents.

Step 2: Type Test (Key Change)

• For power banks and lithium-ion batteries: Sampling is conducted randomly on-site by the certification body, not by the enterprise.
• Sample quantity: Generally 3-5 units, with a sampling base ≥300 units.
• Test items: Safety, performance, and EMC tests in accordance with corresponding standards (e.g., GB 4943.1, GB 31241).
• A type test report is issued by the laboratory after passing the test.

Step 3: Initial Factory Inspection

• On-site inspection of the production factory by the certification body, focusing on:
  • Cell sorting process: Whether each cell is screened with a capacity tester (error ≤±2mAh).
  • Key process control: Documentation and monitoring of welding, assembly, testing, and other processes.
  • Quality assurance system: Incoming inspection, process control, finished product inspection, and other links.
• The inspection covers the entire production chain from raw materials to finished products.

Step 4: Certificate Issuance

• CCC certificates with a 5-year validity period are issued after passing both the test and factory inspection.
• Products must be marked with the CCC logo before leaving the factory; deformed certification logos are allowed for special cases (e.g., lithium-ion batteries with limited volume).

Step 5: Post-Certification Supervision

• Regular supervision inspections by the certification body (usually once a year).
• Inspection content: Product consistency, quality assurance capability, and on-site sampling testing at the production facility.
• Once a year for Class A enterprises (good quality reputation), with higher frequency for other categories.
