The core purpose of battery certification is to prove that the product meets the safety requirements of the target market, while CB certification, through an international recognition mechanism, provides convenience for enterprises to enter multiple national markets.
I. What is Battery CB Certification?
CB certification belongs to the IECEE CB Scheme system and is a product certification system based on IEC international standards.
In simple terms, after enterprises complete tests in accordance with IEC standards, they can obtain CB test reports and certificates, and apply for local certification conversion based on the requirements of different countries.

For battery products, CB certification mainly focuses on safety performance.

Common products involved include:
Lithium-ion battery cell
Lithium-ion battery pack
Rechargeable battery
Portable device battery
Some energy storage battery products

Different types of batteries correspond to different standards. For instance, portable lithium batteries usually involve the safety requirements of the IEC 62133 series.

Ii. Why are more and more enterprises choosing CB battery Certification?
In the past, when enterprises exported to different countries, they often needed to prepare separately:
European certification
"Korean certification"
"Japanese certification"
Australian certification

Each market has its own regulatory requirements.

This approach is prone to generating:
Test repetition
Time increases
The cost of certification has increased.
The advantages of the CB system lie in:
Once a test is completed in accordance with IEC standards, it can serve as an important technical basis for certification applications in multiple countries.

For battery enterprises that are simultaneously expanding into multiple overseas markets, this approach can enhance the efficiency of certification planning.

Iii. What are the main tests for the IEC62133 certification of lithium batteries?
In the battery certification project, safety testing is the core link.

IEC 62133 mainly focuses on the safety requirements for portable secondary batteries and battery packs.

Common tests include:
1. Charging safety test
The main verification is whether the battery is stable under the specified charging conditions.
Follow
Overcharging risk
Temperature change

Abnormal state manifestation

2. External short-circuit test
Simulate the safety performance when abnormal connections occur between the positive and negative terminals of a battery.
Test purpose:
Verify whether the battery may appear
"Fire"
"Explosion"

Structural damage

3. Mechanical safety testing
Including:
Vibration
Fall
Squeeze

The main assessment focuses on the safety capability after being affected by external forces during transportation and use.

Iv. What are the CB certification processes for batteries?

When enterprises apply for battery CB certification, they generally need to go through several stages:

Step 1: Confirm the product type
First of all, it needs to be clear:
Cell type
Battery capacity
Application field
Export countries
Because the standards corresponding to different products may vary.
For example:
There are obvious differences in the testing directions between consumer electronics batteries and industrial energy storage batteries.

Step 2: Prepare technical materials

Usually includes:
Product Specification Sheet
Battery structure data
Circuit protection scheme
Label information
Sample information
Data consistency is of great importance.
In actual projects, many certification delays are not due to testing issues but rather the inconsistency of data parameters.

Step 3: Product testing

Conduct safety tests in accordance with applicable standards.
The key points of the test revolve around
Electrical performance
Mechanical safety
Environmental adaptability
Abnormal usage situation

Step 4: Obtain the CB report and certificate

After the test is completed, enterprises can further apply for local certification based on the demands of the target market.

V. Common Misunderstandings of Battery Enterprises in Obtaining Certification
Misconception One: Believing that CB certification can directly replace all national certifications
CB certification is an international mutual recognition system.

However, there may still be different requirements among different countries, which need to be confirmed in combination with local regulations.

Misconception 2: Focusing only on battery cells while neglecting the design of battery packs
Many enterprises believe that as long as the battery cells pass the test, it is fine.
In fact, in the battery pack:
Protective plate
Structural design
Management System

All of these will affect the final safety performance.

Misconception 3: Certification is only considered after the product has gone into mass production
If it is found during the authentication stage:
The battery cell model has changed
Insufficient protection plan
The structure needs to be adjusted

It may affect the product launch plan.

Vi. How do enterprises plan for International Battery Certification?
For enterprises that hope to expand their overseas markets, it is suggested that
First, determine the export direction during the product design stage.

Understanding the requirements of the target market in advance can reduce the need for later modifications.

Second, establish product technical files.
Including:
Product version record
Test data

Structural data

Third, select the certification scheme based on the market layout.
If an enterprise plans to enter multiple national markets, CB certification is usually worth including in the certification plan.
For instance, Shenzhen Chengce Testing has long been providing international certification services for battery products and can assist enterprises in evaluating certification plans and arranging tests.

With the rapid development of new energy and portable devices, battery safety has become a key focus in the international market.

For export enterprises, choosing the right battery certification scheme not only determines whether their products can enter the target market but also affects the stability of their long-term supply chain.
Understanding the CB certification system, the IEC62133 standard and the testing process can help battery enterprises plan their international market layout more reasonably.
