IEC60598-1 Protection Anainst Overpressure for Li-ion Batteries Pressure Testing

IEC 60598 has been updated to the 2024 version,and additional requirements for Li-ion batteries housing testing have been added.

IEC 60598 annex W4.7,the enclosure or compartment of a battery-operated luminaire that contains a battery that uses Li-ion chemistry with a single cell capacity of 0,2Ah or greater,shall withstand the pressure generated when a cell vents dureing failure.A volume of air of the amount specified in below table shall be injected through a (2,85±0,05)mm diameter orifice into the enclosure at an initial overpressure of 2070kPa±10%.Test fittings used for the test shall not increase the enclosure volume by more than 3 ml.The overpressure within the enclosure shall drop below 70kPa within 30 s without any unintended rupturing damage to the enclosure.

The Zltjc have made the Battery Housing Pressure Test Apparatus,according to IEC60335-1 annex B20.1,IEC60598 annex W4.7.
