To put it simply, IEC62133-2:2017 is an EU battery safety test report. It is necessary to conduct a series of tests for battery safety in accordance with a series of safety test regulations in this standard to meet EU safety requirements. This is also the market. The above lithium battery and the single battery containing alkaline or non-acid electrolyte, battery pack and portable sealed single battery and battery pack are a lot of test standards. Safety inspection

IEC62133-2:2017 Scope of application: This standard specifies the safety requirements and test methods of portable sealed secondary battery cells and batteries (groups) containing alkaline or non-acid electrolytes in their intended use and abuse.

1. Testing and certification cycle:

The test cycle of BCTC double test in the new battery standard IEC 62133-2:2017 has been updated from the original one month to 2-3 weeks. (The low-rate continuous charging time in the new standard is changed to 7 days.) After the test is completed, a data check is required to ensure that the report is written and the certificate is confirmed quickly, and it will take 1-2 days. Safety certification testing

2. Series division:

Lithium batteries cannot be used as a series battery, which means that a certificate can only be used for one model, and multiple models cannot appear. Even batteries with different capacities need to be tested. Nickel batteries can be made as series models, but detailed information is required. Engineers can review the battery structure before it can be made. Safety testing and certification

3. Quantity of samples sent:

The number of samples required by the customer is: we need at least 65 batteries, and 21 batteries for batteries.

Some people may not know the difference between batteries and batteries. Now, with the help of this article, the difference between batteries and batteries is explained as follows:

1) Battery: It is a basic manufacturing unit that provides electrical energy by directly converting chemical energy. It can include electrodes, diaphragms, electrolyte, housing, and terminals. It is designed to be rechargeable.

2) Battery (group): It is composed of single cells and can be used as a power source. Its characteristics are identified by voltage, size, terminal arrangement, capacity and rated capacity. If you really don't know how to make the difference, please send the battery information to the battery testing engineer of Beice for consultation.

4. Which items should be tested by IEC62133?

Generally, the items to be tested by the IEC62133 standard for the battery are: external short circuit test, thermal shock test (bake the cell in a 130 degree (plus or minus 2 degrees) oven for half an hour), extrusion test, and overcharge test , Forced discharge test, transportation process simulation test, button battery AC internal resistance test item (this is the new version added, the new version of IEC is the IEC 62133-2:2017 standard. Medical device safety testing

5. What test content has been changed in the test of the new standard IEC 62133-2:2017?

　　 1. In the new standard IEC 62133-2:2017, testing of lithium batteries: Although the two vibration/shock tests are not required, nickel batteries still need to be tested for these two.

　　 2. Squeeze test. In addition to the pressure reaching 13KN, the new standard requires the instrument to monitor the voltage and deformation of the battery.

　　 3. Add internal short circuit test.

6. How to choose the test standard of the battery cell? For all the batteries to comply with this standard, their batteries also need to be certified according to the corresponding IEC 62133-2:2017 standard, or else they need to be certified together.

If this customer wants to make an IEC 62133-2:2017 test report for a battery, and later finds that its cell has not been CE certified by the European Union, then, it can not directly make the IEC 62133-2 of this battery: In 2017, the battery test report can only be made after the battery cell has been certified. But it can also be done at the same time, but it needs to be tested separately, and then the test report and the EU ce certification certificate can be issued separately.

7. Here, the BCTC double test needs a warm reminder: there are three things that are indispensable for the certification of the battery. Which three are they, that is, the product manual, the specification manual, and the product basic data sheet BOM.
