    In March 2013, the European Electrotechnical Standardization Committee CENELEC officially released the EN 62133: 2013 version of the battery safety standard. This standard is mainly aimed at the safety requirements of single batteries and battery packs containing alkaline or non-acidic electrolytes and portable sealed single batteries and battery packs. The new standard will replace the first edition of EN62133: 2003 issued in 2003. At the same time, the European Electrotechnical Standardization Committee has also designated the expiration date of the old EN 62133 standard. According to the requirements, EN 62133: 2003 will be officially withdrawn on January 10, 2016. The battery testing laboratory reminds major battery manufacturers and battery product manufacturers to import the new version of EN 62133: 2013 as soon as possible, so as not to affect the future export of battery products to Europe.
    The European Commission for Electrotechnical Standards has announced the DOW (mandatory) dates for the new editions of nickel and lithium battery standards EN 62133-1:2017 and EN 62133-2:2017, which means that the old version of EN 62133 will start from March 14, 2020: 2013 will be void and will no longer be used and approved.
    EN62133 report
    This time, EN 62133: 2013 version and the old version of the standard are all quoted from the International Electrotechnical Commission (IEC) standard. From the standard content, EN 62133: 2013 is equivalent to IEC 62133: 2012 edition. The new version of the standard has greater changes in content and technology than the old version. The following are the main differences in the content of the new and old versions of IEC62133.
    · Clause 5.6 updates the requirements for battery cells assembled into batteries.
    For assembling multiple battery packs in a battery box, each battery pack must have independent control and protection circuits.
    · Clause 5.6.2 adds design suggestions for lithium system batteries.
    When the battery is assembled with single or multiple strings in parallel, the designer must consider that the charging voltage of the battery pack must not exceed the upper limit charging voltage value of the single cell/single cell block (cell block).
    · Clause 6 distinguishes the test requirements for nickel-based batteries and lithium-based batteries.
    Nickel system batteries need to meet the requirements of clause 7; lithium system batteries need to meet the requirements of clause 8.
    · Clause 8 adds specific tests and requirements for lithium batteries.
    Clause 8.1.2 The new charging procedure in the second procedure requires the battery to be charged at the maximum and minimum limits of the charging temperature.
    Newly added tests: battery overcharge test (8.3.6), transportation test (8.3.8), and mandatory internal short-circuit test (8.3.9).
    The three tests of vibration, mechanical shock, and low air pressure in the old standard have been incorporated into the 8.3.8 transportation test. The manufacturer can provide documents that demonstrate compliance with UN transport requirements.
    Removed the overcharge test of lithium batteries in the old version.

    · Appendix A adds the charging condition requirements for the safe use of lithium batteries
    In order to ensure the safe use of lithium batteries and lithium batteries, manufacturers designing and producing rechargeable lithium batteries and batteries should strictly observe the corresponding upper limits of charging voltage/temperature/current.
    Since EN/IEC 62133 is a safety requirement for portable rechargeable batteries and battery packs, batteries are now used in many portable IT and AV products. Some of the standards that have been recently released include medical electrical equipment IEC 60601-1 (Ed. 3) A1: 2012 and IT/AV product standards EN/IEC 60950-1: 2005 A2: 2013 and EN/IEC 60065 (Ed. 3). 8) The requirements for portable secondary batteries that must comply with EN/IEC 62133 have been added. Therefore, after the portable secondary battery passed EN/IEC 62133 certification, it has become a prerequisite for most terminal products to pass safety certification.
    How to handle EN62133 report?
    1. Provide an application form
    2. Provide samples and information
    45 batteries, 25 batteries (If the customer's product is to go to Japan, South Korea, France, Switzerland, it must be 25 internal short-circuit batteries, 55 batteries)
    a. Specifications of batteries and batteries,
    b. Factory's ISO or quality plan (choose one of two),
    c. Parameter table and label, CDF (parameter table needs customer seal and return),
    d. Whether there is a test report of UN38.3 (either yes or no, but please specify)
    EN62133 reports the inspection cycle:
    Cycle: 3-4 weeks
