With the development of smart devices, new energy products and energy storage systems, an increasing number of battery enterprises have begun to lay out overseas markets.
However, during the export process, enterprises often find that:
Just because the product quality meets the requirements does not mean it can be sold directly.
Different countries and regions have corresponding requirements for battery safety, so battery certification has become an important preparatory work for enterprises to enter the international market.

Among them, the CB certification, due to its adoption of the IEC international standard system, is widely used by many battery enterprises in their international market certification planning.

Why is certification necessary for battery exports?
The battery stores a relatively high amount of energy inside.
If problems occur during the design, production or use process, it may lead to:
Abnormal temperature
Battery damage
Safety risk

Therefore, markets in various countries usually evaluate the safety capabilities of products through certification systems.

Battery certification mainly focuses on:
Product design safety
Reliability of use

Abnormal state protection

Ii. Which battery products need to be certified?

Common ones include:
1. Consumer electronics batteries
Application
Mobile phone
"Tablet"
Laptop
Smart wearable devices
Key point
Battery cell safety
Cyclic stability
Protective function

2. Power bank

The power bank also includes:
Battery cell
Charge and discharge control module
Overall security needs to be taken into consideration during the certification process.

3. Energy storage batteries

The application environment of energy storage products is more complex.
Usually, attention needs to be paid to:
Long-term operation stability
System protection
Thermal management

The corresponding standards vary for different application scenarios.

Iii. What are the CB certification test items?

The CB certification test for batteries mainly focuses on safety.

Common projects include:
Electrical safety test
Verification
Charge and discharge performance
Voltage stability
Abnormal state protection

Environmental testing

Including:
Temperature cycle
Vibration
Mechanical shock
Used for simulating transportation and usage environments.

Safety protection test

For example:
Overcharge
Short circuit
Forced discharge
Evaluate the performance of the product under abnormal circumstances.

Iv. What problems are enterprises likely to encounter when applying for CB certification?

The management of product models is in a mess

The parameters of products in the same series vary greatly, which will affect the judgment of the certification scope.

The replacement of the battery cell was not re-evaluated
Battery cells are an important factor affecting safety.
After changing the supplier or model, the impact needs to be reconfirmed.

Ignore the differences in the target market

The CB report can assist enterprises in applying for certifications in multiple countries.
However, there may be supplementary requirements in different countries.

V. How to Improve the Efficiency of Battery Certification?

Enterprises can start from three aspects:
Plan ahead
Don't wait until the product goes into mass production to start the certification.

Improve the materials

Maintain
Consistent parameters
The document is complete.
Clear version

Choose a reasonable certification route

According to the sales region
Sales in a single country
Sales in multiple countries

Formulate different plans.

For battery enterprises, certification has become an important part of international market competition.

A reasonable selection of the certification system can reduce the uncertainties in the export process.
CB certification, relying on the IEC international standard system, provides an important path for enterprises to carry out overseas market layout.
Making a good battery certification plan and improving the safety testing system are important foundations for lithium battery products to enter the international market.
