With the increasing dependence of consumers on electric vehicles,electric vehicles have become a part of people’sdaily life. So…power battery is related to the safety of electric vehicles. For the battery, the biggest maintenance isthe thermal runaway of the battery. The thermal runaway of the battery is usually triggered by acupuncture, heating,overcharge and high-power rapid heating. In severe cases, it will cause the battery to ignite spontaneously. When thethermal runaway of the battery reaches a certain temperature, an uncontrollable state will appear, which will causethe temperature inside the battery to rise linearly, and then it will burn and explode.
In order to solve the safety problem of battery thermal runaway, SDA Shangda explosion-proof pressure relief valvecan effectively solve the explosion accident caused by excessive thermal runaway pressure of battery. SDA Shangdaexplosion-proof pressure relief valve is a kind of waterproof, breathable and explosion-proofsafety relief valve, withthe traditional safety relief valve more reliable, more powerful performance. SDA Shangda explosion-proof pressurerelief valveBattery Pressure Relief Valvelet the battery internal pressure is too high to discharge,to achieve the
battery internal and external pressure balance, in this process, water is not.

SDA Shangda explosion-proof pressure relief valveis made of aluminum alloy CNC precisionmachining, and the surface is hardened and anti-corrosion treatment. Compared with the disposableplastic explosion-proof valve in the industry and the regular “vent valve + explosion-proof metal sheet”scheme, it has the advantages of high temperature resistance, non-combustion, large impactresistance, high reliability, simple installation, high waterproof performance, large air permeability,high accuracy of starting point, automatic reset after blasting, 100% detection before shipment toensure product quality, etc., and effectively avoids the problems of functional failure of plasticexplosion-proof valve caused by softening and deformation of plastic shell,ventilation hole andblockage caused by high temperature during blasting, and can be widely usedelectric cars andmotorcycles,battery packs and battery boxes for new energy electric vehicles, hybrid vehicles, high-power energy storage equipment,and various outdoor explosion-proof electrical equipment products
