6 FAQs about [New energy battery cabinet pressure relief valve model]
How does a pressure relief valve work?
The valves also maintain the continuous pressure compensation required for normal battery operation. If a battery gets damaged, liquid electrolytes can escape into the battery housing as hot gases. These must then be released into the environment very rapidly and in a controlled process through a pressure relief valve.
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 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 .
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.
How does a battery safety valve work?
A safety valve was installed in the battery to prevent explosions due to excessive internal pressure. A battery tester (brand: NEWARE) overcharged the battery. Thermocouples measured the temperature. A decibel meter (brand: Delixi, model: DSM-D1) analyzed the opening duration of the battery safety valve , .
