EN IEC 62984-2-2020 pdf download.High-temperature secondary batteries – Part 2: Safety requirements and tests (IEC 62984-2:2020).
This part of IEC 62984 specifies safety requirements and test procedures for high-temperature batteries for mobile and/or stationary use and whose rated voltage does not exceed 1 500 V.
This document does not cover aircraft batteries, which are covered by IEC 60952 (all parts), and batteries for the propulsion of electric road vehicles, covered by IEC 61 982 (all parts).
NOTE High-temperature batteries are electrochemical systems whose cells’ internal minimum operating temperature is above 1 00 °C.

3.1 Battery safety
3.1.1 rated insulation voltage
rated value of the RMS withstand voltage assigned by the manufacturer to the equipment or to a part of it, characterizing the specified (long-term) withstand capability of its insulation
Note 1 to entry: The rated insulation voltage is not necessarily equal to the rated voltage of equipment which is
primarily related to functional performance. [SOURCE: IEC 60050-31 2:201 4, 31 2-06-02]
3.1.2 functional insulation
insulation between conductive parts, necessary for the proper functioning of the equipment
[SOURCE: IEC 60050-1 95:1 998, 1 95-02-41 ]
3.1.3 supplementary insulation
independent insulation applied in addition to basic insulation in order to provide protection against electric shock in the event of a failure of basic insulation
[SOURCE: IEC 60050-1 95:1 998, 1 95-06-07, modified – “for fault protection” has been replaced by “in order to provide protection against electric shock in the event of a failure of basic insulation”.]
3.1.4 reinforced insulation
insulation of hazardous-live-parts which provides a degree of protection against electric shock equivalent to double insulation
[SOURCE: IEC 60050-1 95:1 998, 1 95-06-09, modified – The note has been omitted.]
3.1.5 double insulation
insulation comprising both basic insulation and supplementary insulation
Note 1 to entry: Basic and supplementary insulation are separate, each designed for basic protection against electric shock.
[SOURCE: IEC 60050-1 95:1 998, 1 95-06-08, modified – The note to entry has been added.]
3.1.6 extra-low voltage
ELV voltage not exceeding the maximum value of the prospective touch voltage which is permitted
to be maintained indefinitely under specified conditions of external influences [SOURCE: IEC 61 1 40:201 6, 3.26]EN IEC 62984-2 pdf download.
