A safety valve was installed in the battery to prevent explosions due to excessive internal pressure. A battery tester (brand: NEWARE) overcharged the battery. Thermocouples measured the temperature. A decibel meter (brand: Delixi, model: DSM-D1) analyzed the opening duration of the battery safety valve , .
The device size is 335 mm 9 210 mm 9 120 mm (L 9 W 9 H). The puncture valve uses specially treated alu-minum foil to seal the sealing device in the perfluorohexanone pipeline, and uti-lizes the ignition head to activate the thimble piercing the aluminum foil to form a passage.
Experimental tests have shown that conventional PRV that rely on pressure differentials are difficult to open in time after the battery safety valve is opened. The VE generated during battery TR cannot pass through the PRV membrane. In addition, numerical studies revealed that larger sizes of PRV are better.
Pressure relief valve (PRV) on LCBPs serves as crucial backup protection devices, effectively reducing the accumulation and explosive potential of FEGs . Similar to the principle of PRVs used in situations such as mines and tunnels , the PRV installed on LCBPs rapidly opens when triggered by specific pressure.
The inherent safety issues associated with LIBs are difficult to eliminate . Pressure relief valve (PRV) on LCBPs serves as crucial backup protection devices, effectively reducing the accumulation and explosive potential of FEGs .
The size of the PRV largely determined the pressure relief efficiency. The front panel of the pack was equipped with BMS, circuit breakers, terminal blocks, liquid cooling pipeline controllers, etc., which imposed strict restrictions on the size of the PRV.
