What is BS EN IEC 62485‑2 – Secondary batteries and battery installations about?
BS EN IEC 62485 is a series of international standards that discusses safety requirements for secondary batteries and battery installations.
BS EN IEC 62485‑2 applies to stationary secondary batteries and battery installations with a maximum voltage of DC 1 500 V (nominal) and describes the principal measures for protections against hazards generated from:
- Electricity
- Gas Emission
- Electrolyte
NOTE: BS EN IEC 62485‑2 provides requirements on safety aspects associated with the erection, use, inspection, maintenance and disposal. It covers lead-acid and NiCd / NiMH batteries.
Who is BS EN IEC 62485‑2 – Secondary batteries and battery installations for?
BS EN IEC 62485‑2 on secondary batteries and battery installation applies to:
- Manufacturer of batteries and fuel cells
- Quality testing personnel
- Manufacturers of rechargeable battery
- Electric engineer
Why should you use BS EN IEC 62485‑2 – Secondary batteries and battery installations?
The storage battery, secondary battery, or charge accumulator is a cell or combination of cells in which the cell reactions are reversible. This means that the original chemical conditions within the cell can be restored by passing current to flow into it: that is, by charging from an external source. Stationary batteries are made for standby or stationary applications.
BS EN IEC 62485‑2 describes the safety requirements comprise the protective measures to protect from hazards generated by the electricity, the electrolyte, and the explosive gases when using secondary batteries. In addition, measures are described to maintain the functional safety of batteries and battery installations.
BS EN IEC 62485‑2 provides you with the measures which are taken in stationary battery installations for protection against either direct contact or indirect contact or both direct and indirect contact. BS EN IEC 62485‑2 provides guidance on the protection against electric shock, protection against direct contact and protection against indirect contact.
BS EN IEC 62485‑2 exemplifies the safety requirements that help you achieve precision in terms of secondary batteries and battery installations.
What’s changed since the last update?
BS EN IEC 62485‑2:2018 supersedes BS EN 50272‑2:2001, which is withdrawn.
