What is Korea KC Battery Certification

"KC" certification is a national unified certification mark implemented by the Korean National Standards Committee, and lithium batteries are included in the KC certification catalog as a compulsory certification product.

KC's certification scope for battery products

1. Single battery (Cell): portable;

2. Battery (Pack): The single cells are assembled in parallel in a row;

3. Portable lithium single cells or batteries with navigation function are applicable regardless of the energy density per volume (used in harsh conditions inside the car);

4. Single cells and batteries used in portable medical devices, barcode and credit card readers are all applicable objects;

5. Carrying machines: MP3, electronic dictionary, PMP, notebook computer, digital camera, etc.;

6. Portable product segmentation: batteries used in mobile products are also subject to certification;

7. Non-certified objects: vehicle drive, industrial, medical.

Update of Regulation KC 62133-02 (2020) for Button Battery Certification Requirements

For rechargeable button-type lithium batteries, if they are soft packs, they will fall into the control scope of KC 62133-2 from mid-January 2021, and you need to apply for a KC safety certificate. If it is a button battery with a metal casing, it is not within the scope of KC control, and you can still use IEC 62133-2:2017 CB to transfer the KC certificate.

Cell and battery series division rules

●Cell:

1. The shape is the same, the cylinder and the square are applied separately;

a. Cylindrical (capacity ≥ 2400mAh, capacity ≤ 2400mAh)

b. Square/Rhombus

(Capacity ≥ 5000mAh, 5000mAh ≥ Capacity ≥ 3000mAh,

3000mAh≥Capacity≥1500mAh, Capacity≤1500mAh)

2. The positive and negative materials are the same;

3. The charging limit voltage is the same.

●Battery:

1. The circuit, protection board and protection device are the same;

2. Cells need to pass KC certification

3. 25 main test models (maximum capacity) and 5 derivative models

KC certificate Precautions

1. Is the KC certificate transferable?

The same model, the same factory, the Korean agent and the factory cannot hold the certificate at the same time. The original Korean agent holds the certificate and can be converted to the factory certificate, but the original factory certificate cannot be transferred to the Korean agent.

2. The model number applied for in the same institution cannot be repeated.

3. It is recommended not to apply for KC certification directly for lithium battery products. You can apply for CB certification first, and then use CB certification to transfer to KC certification. There are two advantages:

4. The cost is relatively cheaper. The cost of directly doing KC is relatively expensive, and it is necessary to send samples to South Korea for testing, which increases the express fee and the difficulty of certification. By doing CB first, and then using CB to apply for KC certification, the cost is relatively cheaper, and there is no need to send samples to Korea.

5. The cycle is relatively shorter. To do KC certification directly, you need to send samples to South Korea for testing. It takes more than 3 months to send samples and test cycles. To apply for KC through CB, the CB certification cycle is 3-4 weeks. It only takes a few weeks to transfer to KC, and it takes more than a month. KC certification can be obtained, which is more efficient.

6. If the method of applying for CB first and then applying for KC is adopted, CB can only be used for a single model. How to apply for KC in series?

When making CB, you only need to make a battery with the largest capacity, then other battery models with smaller capacity and meeting the requirements of the KC series can be applied for the series when applying for KC, and only need to add some additional model fees.
