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 is liquid cooled battery energy storage system (lcbess)?
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.
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 .
Which LCBP monitoring point has the smallest peak overpressure?
After the PRV is opened, monitoring point #4 experiences the lowest pressure, resulting in the smallest peak overpressure compared to other monitoring points inside the LCBP. Fig. 5 (a) shows that the PRV at position III has the best pressure relief effect.
What is a pressure relief valve (PRV)?
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.
How does the size of a PRV affect pressure relief efficiency?
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.
