This paper addresses the safety concerns associated with LCBPs and proposes an effective solution for explosion relief. Installing an electric-controlled pressure relief valve with battery fault detection capability on a liquid-cooled battery pack can prevent explosions caused by thermal runaway. 1. Introduction
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, .
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.
During a battery TR event, the flammable and explosive gases (FEGs) vented by the battery are prone to accumulating and result in explosions . Additionally, the shock waves produced when a sealed box explodes are more difficult to dissipate, further damaging the batteries in normal conditions.
The rapid advancement of battery energy storage systems (BESS) has significantly contributed to the utilization of clean energy and enhancement of grid stability . Liquid-cooled battery energy storage systems (LCBESS) have gained significant attention as innovative thermal management solutions for BESS .
Jin et al. found that overcharging an LFP battery pack can generate enough FEGs to cause an explosion. The FEGs are mainly vaporized electrolyte (VE), with the concentrations of H 2 and CO being far below their lower explosive limits .
