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.

An explosion-proof valve is a critical safety feature in a lithium-ion battery designed to safeguard it against thermal runaway. Usually located on its casing, this valve monitors internal pressure changes before opening to release any built-up pressure within and prevent damage.
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
Explosion-proof valves keep their inner pressure below a preset threshold, enabling normal battery operation. Should that pressure exceed this limit, however, the explosion-proof valve opens to release any trapped gases within and lower its pressure as quickly as possible, helping protect the battery against rupture or explosion.
Prismatic lithium-ion batteries in portable electronics typically incorporate an explosion-proof valve at the top of their battery case, designed to open easily in response to increasing internal pressure. When an internal short circuit or overcharging occurs, this reaction could produce heat and gas, generating an explosion if leave unmanaged.
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 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.
