In the certification process of lithium-ion batteries and related products, the requirements for key components in the CCC type test report are of vital importance, directly affecting the compliance and effectiveness of the certification. As a professional certification service provider, China Certification Union Technology Co., Ltd. will provide you with an in-depth interpretation of the relevant core points.

Standard consistency is the foundation. The standards on which each component in the list is based must strictly correspond to those clearly listed in the TC03 resolution list, and no deviation is allowed. This is a prerequisite for ensuring that the performance of key components meets the certification requirements and also an important basis for subsequent testing and evaluation.

The information filling should be standardized. The specification information and manufacturer information of each component must be accurately filled in Chinese. Standardized information presentation not only facilitates verification by regulatory authorities but also provides a clear basis for the quality traceability of enterprises themselves, avoiding certification delays caused by ambiguous information.

The control parameters should be clear. The control parameters of key components must be clearly presented, for example, the thickness of the diaphragm needs to be precise to the micrometer. These parameters are important indicators for measuring the quality of key components and directly affect the safety and reliability of batteries. Clear parameter marking is a key link to ensure product quality.

The rules regarding the change of information on key components are equally clear. If it is only about correcting typos, corrections can be made. However, when changing suppliers, the normal change procedures must be followed. It is particularly important to note that once the key components of the four major materials of the battery cell are changed, a full-item test must be conducted to ensure that the changed key components still meet the certification requirements.

There are special exemption circumstances. When the charging limit voltage multiplied by the maximum charging (discharging) current is less than 15VA, the list may not include critical components such as printed circuit boards, packaging materials, and wires.

Strictly adhering to the above requirements is the key to ensuring that lithium-ion batteries and related products can smoothly pass the CCC certification.
