How does a battery safety valve work?

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 , .

What is the temperature of a battery at 7391 s?

At 7391 s, the safety valve of battery was opened, and the surface temperature of the battery was 78.2 °C. The concentrations of H 2 and CO were close to 0 ppm. After 1 s, the sound recognition module detected the sound of the battery’s safety valve opening, and the microcontroller actuated the PRV.

Can a PRV be opened after a battery safety valve is opened?

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.

What is the ignition location of a battery module?

To make the study more generalizable, the ignition location was designated as the center of the upper surface of the battery module ( x axis: 2.375 m, y axis: 0.5 m, z axis: 1.2 m). Flame, temperature, and overpressure are crucial data of interest in this study.

What are the components of LFP battery electrolyte?

In Section 2.1, the main components of the LFP battery electrolyte used in the experiment are EC, DMC, and EMC, with specific proportions of 2 mol C 3 H 4 O 3: 3 mol C 3 H 6 O 3: 5 mol C 4 H 8 O 3.
