What is BS EN 62133‑2 - Secondary cells and batteries about?
BS EN 62133‑2 is a European standard that discusses lithium systems of secondary cells and batteries containing alkaline or other non-acid electrolytes.
BS EN 62133‑2 specifies requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries containing non-acid electrolytes, under intended use and reasonably foreseeable misuse.
Who is BS EN 62133‑2 – Secondary cells and batteries for?
BS EN 62133‑2 on prismatic and cylindrical cells applies to:
- Manufacturer of battery and cells
- Quality testing personnel
- Electrical engineer
- Suppliers of cells
Why should you use BS EN 62133‑2 – Secondary cells and batteries?
A secondary cell is a basic manufactured unit providing a source of electrical energy by direct conversion of chemical energy, that consists of electrodes, separators, electrolytes, containers and terminals, and that is designed to be charged electrically. Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
BS EN 62133‑2 provides a quality plan that helps you in manufacturing reliable products. BS EN 62133‑2 lets you prepare and implement the quality plan that defines procedures for the inspection of materials, components, cells and batteries and that covers the whole process of producing each type of cell or battery.
BS EN 62133‑2 provides guidance regarding the safety of a lithium-ion secondary battery that help you to ensure the safe use of lithium-ion secondary batteries, manufacturers who design and produce lithium-ion secondary cells or batteries shall strictly observe the requirements are specified in BS EN 62133‑2. In this manner, you can conduct your operations with ease, making sure that the product is handled efficiently.
