5 General safety considerations
5.1 General
The safety of lithium secondary cells and batteries requires the consideration of two sets of applied conditions:
a) intended use:
b) reasonably foreseeable misuse.
Cells and batteries shall be so designed and constructed that they are safe under conditions of both intended use and reasonably foreseeable misuse. It may also be expected that cells and batteries subjected to intended use shall not only be safe but shall continue to be functional in all respects.
It is expected that cells or batteries subjected to misuse may fail to function. However, even if such a situation occurs, they shall not present any significant hazards.
Potential hazards which are the subject of this document are:
a) fire,
b) burstlexplosion,
C) critical electrical short-circuit due to leakage of cell electrolyte,
d) venting which continuously vents out flammable gases,
e) rupture of the casing of cell, module, battery pack, and battery system with exposure of internal components.
Conformity with 5.1 to 5.6 is checked by the tests of Clauses 6, 7, and 8, and in accordance with the appropriate standard (see Clause 2).
5.2 InsulatIon and wiring
Wiring and its insulation shall be sufficient to withstand the maximum anticipated voltage, current, temperature, altitude and humidity requirements. The design of wiring shall be such that adequate clearances and creepage distances are maintained between conductors. The mechanical integrity of the whole battery system (cell/module/BMS) and their connections shall be sufficient to accommodate conditions of reasonably foreseeable misuse.
5.3 Venting
The casing of a cell, module, battery pack, and battery system shall incorporate a pressure relief function that will preclude rupture or explosion. If encapsulation is used to support cells within an outer case, the type of encapsulant and the method of encapsulation shall neither cause the battery system to overheat during normal operation nor inhibit pressure relief.AS IEC 62619 pdf download.
