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
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 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 .
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.
A well installation position of PRV can enhance the pressure relief effectiveness and reduce the secondary damage caused by explosions to the batteries. Five different installation positions for the PRV were selected in this study to assess the impact of varying horizontal and vertical positions on the pressure relief efficiency.
The liquid-cooled battery energy storage system (LCBESS) has gained significant attention due to its superior thermal management capacity. However, liquid-cooled battery pack (LCBP) usually has a high sealing level above IP65, which can trap flammable and explosive gases from battery thermal runaway and cause explosions.
