1What is' IEC '?
IEC refers to the International Electrotechnical Commission. The purpose of IEC is to promote international cooperation on standardization and related issues in the field of electrical and electronic engineering, and to enhance mutual understanding among nations. IEC publishes various publications, including international standards, and hopes that members can use these standards in their own standardization work when conditions permit.
IIWhat is "IEC62133"?
IEC/EN62133 is mainly a standard testing specification for the safety requirements of portable sealed secondary single cells and battery packs made from them for use in portable devices, which contain alkaline or other non acidic electrolytes.
Analysis:
Secondary single cell and battery pack: rechargeable single cell and battery pack.
Contains alkaline or other non acidic electrolytes: mainly targeting nickel and lithium series.
In short, IEC/EN62133 is mainly a safety testing standard for rechargeable nickel and lithium single cells and battery packs.
IIIWhy do we need to do 'IEC62133'?
IEC62133 "is a type of testing item for batteries before CB certification.
4Documents to be provided before testing:
1. Testing Application Form (Note: The models of cells and packs on the application form must be consistent with the specifications of the battery cells and packs);
2. Specification sheet for battery cells and battery packs;
3. CDF list of battery cells or batteries (to be signed, stamped and returned), providing specifications and certificates for PCB, electrolyte or separator (if any);
4. If the battery cell is made of polymer, sign and stamp a statement providing the polymer battery cell (to be returned);
5. Battery cell or battery pack nameplate;
6. Corresponding product UN38.3 test report (if not available, a section on UN38.3 transportation testing needs to be done here);
7. Provide ISO9001 certificate for battery manufacturers;

6、 Test cycle:15-20 working days;
7、 Label requirements:
5.3 Labels
Each individual battery or battery should be clearly and durably labeled with the following information:
---Rechargeable lithium batteries or lithium-ion batteries;
---According to the model specified in 5.1;
---Polarity;
---Production date (can be represented by code);
---Manufacturer or supplier name or identification.
The battery identification also needs to provide the following information;
---Rated capacity;
---Nominal voltage.
5 models and logos
5.1 Single cell battery and battery model
Batteries are named in the following form:
N1A1A2A3N2/N3/N4-N5
Single cell batteries are named in the following form:
A1A2A3N2/N3/N4
Here:
N1The number of individual cells connected in series in a battery;
1. Negative electrode system code; I represents lithium-ion system, L represents metallic lithium or lithium alloy system
2. Positive electrode system code; C represents cobalt based positive electrode N represents nickel based positive electrode M represents manganese based positive electrode V represents vanadium based positive electrode T represents titanium based positive electrode
3 battery shape code; R is cylindrical and P is prismatic
N2. Take the integer value in millimeters for the diameter (cylindrical) or thickness (prismatic) upwards.
NTake the integer value in millimeters for the three widths (prismatic) upwards. (Cylindrical batteries are not included in this category)
NTake the integer value of the 4 total heights upwards, in millimeters.
If the size is less than 1mm, use mm/10 (taken as an integer) to represent the size, and add the letter t. before the integer
NThe number of parallel connected single cells with 2 or more. If the value is 1, do not write it
Example: ICR19/66 represents a cylindrical lithium-ion single cell battery with a diameter of 18mm~19mm and a height of 65mm~66mm, using cobalt as the positive electrode.
1ICR20/70 represents a lithium-ion battery with a diameter of 19mm~20mm and a height of 69mm~70mm, composed of a cylindrical single cell battery with cobalt based positive electrode.
8、 Other:
1. Mandatory internal short circuit is only required for exports to South Korea, Japan, France, and Switzerland.
