3.7V Rechargeable Lithium Polymer Batteries Manufacturer Supplier, IEC62133 certificated lithium polymer batteries for your new device
From 1st May 2012, the Lithium Polymer cells and Lithium Polymer Batteries must be fully tested to IEC 62133 for CB certification.
About the IEC62133 Standard
IEC62133 is the most important standard for exporting Lithium Polymer Batteries, including those used in IT Equipment, tools, laboratory, household, and medical equipment.
In December 2012, the International Electrotechnical Commission (IEC) officially released the IEC62133 second edition IEC62133:2012 (2nd Edition), an international safety standard for Lithium Polymer battery products. This standard is mainly for the safety requirements of single Lithium Polymer cell batteries and LiPo battery packs and portable sealed single cell batteries and LiPo battery packs containing alkaline or non-acid electrolytes (including LiPo Batteries which is lithium polymer batteries, lithium ion(Li-Ion) cells, nickel-hydrogen batteries, nickel-cadmium batteries, etc.).
The second edition will have some very significant changes related to Lithium Polymer Batteries.
Part I: Cells
The second edition of IEC62133 have the most impact on lithium ion cell manufacturers and dealers, it also important for company who use the lithium ion cell. The changes related to Lithium Polymer cells fall into three categories:
• Cancel redundant tests with other standards
• Modify existing tests
• Completely new requirements
1.Cancel redundant tests with other standards
The main focus is to delete the items covered by the United Nations Manual Of Tests and Criteria(UN38.3). The tests deleted are:
Vibration
Mechanical Shock
Low Pressure(Altitude Simulation)
Cell Protection Against High Rate Charging(not a UN38.3 test)
2.Modify existing tests
The most important of these changes is related to how the sample is prepared for testing. In the first edition of the standard, samples were charged at room temperature (20°C ±5°C) according to the manufacturer’s recommended charging method. The second edition includes two charging processes: one at room temperature, and one new program at high and low specified operating temperature ranges (10°C and 45°C if not stated). The new charging method also requires charging at the maximum rated charge current of the product. This process only requires samples at the cell level for short circuits, thermal abuse, crushing, and forced internal short tests.
In the constant voltage test, a continuous low-rate charge test was corrected to a constant charge. This modified test requires the Lithium Polymer battery to be charged for 7 days at the manufacturer’s recommended charge current and voltage limits.
Modifications to the crush test included clarification of the test, indicating that the crushing only needs to be done along the broadside of the cell. In addition, termination criteria for 10% deformation of cells were also added.
A more important change is to divide the short circuit into separate parts of the Lithium Polymer batteries. The second version of the cell was modified to contain only one test temperature and provide a more stringent range of circuit resistances.
3.Completely new requirements
The most significant change in the second edition is the addition of a new test——Forced Internal Short Circuit test. The test procedure very explicitly describes a method that requires the test facility to fully charge a Li-Ion cell, then open it and remove the jellyroll. Once the cell is removed from the can, a small Nickel particle of a specific shape and size is to be place in a very specific location of the cell jellyroll. Following the placement of the particle, the affected jellyroll is to be crushed.
Pate II: Batteries
For Lithium Polymer battery manufacturers, the IEC62133 edition2 proposal will have less impact on Lithium Polymer batteries manufacturers than LiPo battery suppliers. Lithium Polymer Batteries manufacturers’ testing and demand will actually be reduced. The changes related to Lithium Polymer batteries fall into three categories:
• Revised Charging Procedure
• Reduced Sample Requirement
• New testing
1.Revised Charging Procedure
Similar to the cell level charging process changes, the Lithium Polymer battery level will have a modified charging process, but this will only affect the Lithium Polymer Battery level of a test. This change comes from Japan’s lithium-ion battery and battery test requirements, and it state that samples used for short-circuit testing must be charged in an environment which is equal to the ambient temperature upper and lower: assumes 45°C and 10°C if not provided by the manufacturer. All other tested units on the LiPo battery level were charged at room temperature (20°C).
2. Reduced Sample Requirement
The subcommittee’s test requirements for Lithium Polymer batteries are more comprehensive than ever. Therefore, the amount of test required by IEC 62133 at the Lithium Polymer battery level has dropped significantly. The testing that has been completely removed as a result of this review is:
• Vibration
• Temperature Cycling
• Mechanical Shock
The result is that the change reduces the required number of samples for testing from 31 for First Edition testing to 21 for Second Edition testing.
3.New Test
A new test has also been added to the Lithium Polymer battery level, designed to simulate the Lithium Polymer battery charging time longer than the manufacturer’s use of a higher charging rate. This test is performed on a fully discharged five Lithium Polymer battery packs, and the charge the Lithium Polymer batteries with a current of two times the rated current, and an upper voltage limit that is set to the maximum voltage available from the charger to the Lithium Polymer battery. If you do not know the charger’s maximum voltage, 5 volt per cell (or cell string) will be used. The current is maintained until the maximum charge voltage is reached and the temperature is monitored during the test. The termination of the test is defined as the temperature is stable, the highest voltage is reached, with acceptance criteria of no fire and no explosion.
