Rupture discs open in milliseconds at predetermined thresholds to provide active pressure relief and prevent catastrophic explosions. These space-saving products simplify battery design, as they eliminate the need for an additional component.
The battery compartment must be able to safely release 150% of the maximum pressure (calculated using the formulas provided in section 5.3) which can be generated during a violent battery venting without the compartment shattering, fragmenting, releasing batteries, or allowing any parts to "fly" off the equipment.
Battery compartment design recommendations to niinimize equipment damage and injury as a result of violent ventings that may occur when the batteries are installed in equipment are addressed in detail.
When confined in a battery compartment the pressure would be high, hence the problem. The smaller the free volume in the battery compartment, the higher the pressure. Many of the newer equipments are small hand-held units which utilize cylindrical batteries such as the BA-5800/U and BA-5600/U.
Battery compartments must be tested to 150% of the design pressure. A successful test is one in which there is no shattering of the battery compartment or the expulsion of the battery or any pieces of the battery compartment (including any parts of the equipment interfacing the battery compartment).
For compartments containing multiple LiSÜ2 batteries, only one dummy battery will be used for distribution of gases. The remaining batteries will be actual solid (empty) battery cases or solid structures which will not allow any gas to enter into them during testing.
The objective of battery compartment testing is to apply test pressures as rapidly as possible in an attempt to closely simulate an actual violent venting. Figure 5.1 shows a representation of the test apparatus used by the U.S. Army Communications-Electronics Command (CECOM), Fort Monmouth, NJ, to perform this testing.

A pressure relief valve is a mechanical device which allows a gas or liquid to escape from a section of a fluidic system when the pressure exceeds a predetermined limit. Pressure relief valves originally became popular for use in the boiler systems used to heat buildings. A boiler creates hot water or steam which is distributed throughout a
regulation mechanism that releases gas from the battery to maintain the pressure in the battery within a predeter-mined range. The pack case includes a port and a pres-sure
As these gases accumulate, the battery''s internal pressure rises. When the pressure exceeds specific safe limits, the EV battery vent opens to release the built-up gases. This controlled release prevents the battery casing from rupturing and mitigates the risk of fire or explosion. Related: Venting Technology Critical to EV Battery Life
Battery venting is a critical safety feature in batteries that prevents the build-up of pressure and gas.
