6 Frequently Asked Questions about “Explosion-proof battery box pressure relief device”

Can electric-controlled pressure relief valve prevent explosions caused by thermal runaway?

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

What happens if a battery tr explodes?

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.

What happens if a LCBP battery explodes?

The peak overpressure inside the LCBP during the explosion is 215.94 kPa when the PRV size is 4 cm × 4 cm. This enormous pressure can deform and rupture the LCBP casing, as observed in the experimental results in Section 2.1. The adjacent LCBP batteries may experience TR due to mechanical or thermal abuse, posing a serious safety threat.

What happens if the safety valve outlet of LCBP explodes?

The temperature of the safety valve outlet of battery increased from 40.3 to 215.4 °C. The high temperature inside the battery ignited the electrolyte. Flames erupted from the safety valve outlet of battery, causing the FEGs in the LCBP to explode. The explosion damaged the LCBP casing, deforming the top cover and body.

How to prevent LCBP from explosions?

The test results showed that this approach prevented LCBP from explosions effectively. The PRV in LCBPs must be integrated with a novel and effective battery fault monitoring method. This paper only provided one possible solution as a proof-of-concept. Various alternative methods can replace different parts of the PRV.

What is a pressure relief valve (PRV) on a LCBP?

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 .
