Battery testing according to IEC 62133-1:2017 and IEC 62133-2:2017

New requirements on testing, documentation and technical monitoring

IEC 62133-1:2017 and IEC 62133-2:2017 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications

This third edition of the standard is dedicated to the use of sealed secondary cells and batteries containing alkaline or other non-acid electrolytes which are used in portable applications defining requirements for their safe operation. Unlike the former editions of the standard the current one was subdivided into two parts - part 2 exclusively dealing with batteries containing lithium-based electro-chemical systems and part 1 determining specifications for nickel-based systems.

The scope of testing now also includes vibration and shock tests in accordance with the UNT 38.3 test as well as considerations on single fault cases during the short circuit test. Documentation requirements are extended including the following data and also technical prerequisites:

  • A safety analysis and description with respect to safely monitoring voltage, current and temperature values. The safety analysis should identify those components of the protection circuit critical for the protection against short circuit, overcharging and over-discharging.
  • A description for simulating a single fault condition for each safety-relevant component (MOSFET, PTC, fuse, etc.) realising the short-circuit protection.
  • An option for measuring and evaluating the cell temperatures before and during the discharging process with regard to keeping the permissible temperature limits.
  • An option for measuring and evaluating the cell voltages during a deep discharge with regard to complying with the then not permissible charge.

We are acknowledged in the CB Scheme of the IECEE both as CBTL (CB test laboratory) and NCB (national certification body) for testing according to IEC 62133-1:2017 and IEC 62133-2:2017.
