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
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 .
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 adjacent LCBP batteries may experience TR due to mechanical or thermal abuse, posing a serious safety threat. The peak overpressure inside the LCBP decreases by 89.1% to 23.53 kPa when the PRV size is 8 cm and by 97.3% to 5.83 kPa when the PRV size is 12 cm. However, the reduction of peak overpressure from 8 cm to 12 cm is only 17.7 kPa.
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 .
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.
