In recent years, the state’s policy support in the pure electric market has been increasing, and the pure electric vehicle market hasentered a stage of rapid development. Many interested people have begun to switch to the pure electric venicle market. This is one ofthe factors. The greater reason for the development of the pure electric vehicle market is that the current consumer consumptionconcept is becoming more and more mature, and the demand for car purchase is becoming more and more clear., The acceptance ofpure electric vehicles is getting higher and higher. There are many kinds ofindependent brands of pure electric vehicles on themarket, among which the most concemed about pure electric vehicles is their batteries, which is the basic guarantee of pure electricvehicles. The following Shangda waterproof and breathable solution solver will explain several major elements about the safety oftrams.

we all know that any kind of battery has a lot of chemicals inside it. These substances produce a large amount of mixed liquid and gasin the process of charging and discharging. In this process, the battery will continue to accumulate pressure,if these pressures arenot balanced or released in a sare way,then ifthe shell has a itle deformation or leakage,the battery wll become a bomb,causinggreat harm to the human body.

in the production of batteries, the general use of fully closed assembly process, the application of waterproof explosion-proofventilation valve. This valve allows the battery to travel safely in 50cm of water. Ifthe internal pressure of the battery is too large, SDAShangda explosion-proof valve and waterproof ventlation valve can also quickly release the internal pressure of the battery to preventexplosion. This also solves the problem of self-explosion of new energy vehicle batteries!SDA Shangda M20 *1.5 one-way breathable explosion-proof valve (hereinater referred to as one-way vaive)is a high-tech productdesigned and developed with a new concept 1ts main material is made of aluminum alloy CNC precision machining, and its surface ishardened and ant-corrosion treatment. Compared with the disposable plastic explosion-proof valve and the regular “explosion-proofmetal sheet scheme in the industry, it has the advantages of high temperature resistance, non-combustion, large impact resistance.high rellability,simple installation, high waterproof performance, high precision of starting point, automatic reset after blasting, 100%detection before shipment to ensure product quality, et., and effectively avoids the problems ofunctional fallure of plastic explosion-proof valve caused by softening and deformation of plastic shell, adhesion of vent holes and blockage caused by high temperature
during blasting.
SDA Shangda explosion-proof valve, waterproof ventilation valve features:(1) The waterproof, dustproof and oi-proof performance of the ventilation valve is relatively high, and the protection level has reached
IP68.(2) The ventilation valve has stable chemical properties, can withstand high and low temperature changes, and has very strong anti-aging properties. The product can also be used safely in harsh environments.(2)(3)In an environment with a large temperature difference, it can effectively prevent condensation and fogging, and improve theservice life of the product.
(4) The product has strong micro-heat dissipation and pressure balance performance, which improves the integrity of the product.
