CE testing and certification of batteries

CE certification is a type of safety mark certification, regarded as a passport for manufacturers to open and enter the European market. All products with the CE mark can be sold in various European member states without meeting the requirements of each member state, thus achieving free circulation of goods within the EU member states. The product with the CE mark complies with the main requirements of relevant European directives and is used to confirm that the product has passed the corresponding conformity assessment procedure and the manufacturer's declaration of conformity. However, the CE mark affixed to the battery cannot be understood in this way.

The main factors affecting the safety performance of lithium-ion batteries include the thermal stability of electrode materials, the thermal stability of electrolyte components, the ratio of positive and negative electrode materials, and battery structure. Structurally, lithium-ion batteries can be divided into three parts: battery cells, auxiliary parts such as protective circuits, and battery shells. The safety of a battery mainly depends on the battery cell, and the CE mark affixed to the battery is mainly because the electronic components and printed circuit boards (PCBs) in the auxiliary part of the battery need to meet the requirements of the Electromagnetic Compatibility Directive (EMCD). But in fact, the electromagnetic radiation generated by these auxiliary parts in the battery is relatively small, which can basically meet the requirements of EMCD. Therefore, the CE mark affixed to the battery only indicates that the auxiliary part of the battery meets the requirements of EMCD, and cannot indicate that the battery meets the relevant safety requirements.

However, electrical products entering the EU (such as mobile phones, electric toys, electric tools, etc.) need to meet the requirements of the EU's new method directive and be labeled with the CE mark. As an accessory for many end products (such as mobile phones, electric toys, etc.), the safety of batteries needs to be considered in conjunction with these end products. Therefore, many end product customers, out of consideration for their own product safety, require that their components also be labeled with CE marks, in order to better meet the requirements of relevant directives.

Therefore, if the battery products of export enterprises can meet the requirements of the EMCD directive and affix the CE mark, it will enhance their competitiveness in the market and strive for a larger market for the enterprise.
