PUW Power Battery Explosion-Proof Valve, Help New Energy Electric Vehicles To Meet The National Three Strong Standard Requirements

The safety of electric vehicles is the focus of consumers' attention, and it is also the fundamental guarantee for the sustainable and healthy development of the new energy vehicle industry. In recent years, the rapid development of new energy vehicles in China has led to a strong demand for power batteries. However, at the same time, electric vehicle battery fire and burn accidents occur frequently, which is like holding an untimely bomb, life safety is always under threat. People are worried about the safety of new energy vehicles and their batteries.

       On May 12, GB 18384-2020 “Electric Vehicle Safety Requirements”, GB38032-2020 “Electric Bus Safety Requirements” and GB 38031-2020 “Electric Vehicle Power Battery Safety Requirements”, three mandatory national standards (hereinafter referred to as the “three standards”), organized by the Ministry of Industry and Information Technology (MIIT), were adopted by the State Market Supervision and Administration of the People's Republic of China (SMAC). (hereinafter referred to as “the three strong standards”) were approved and released by the State Administration of Market Supervision, Administration of Standardization of the People's Republic of China and the National Standardization Administration of the People's Republic of China.

      In response to the “three strong standards”, as a professional designer and developer of waterproof and breathable valves and Explosion-Proof Valves for new energy vehicles, PUW has designed and developed the PBA series of bi-directional breathable waterproof and breathable Explosion-Proof Valves, PDA series of one-way breathable and Explosion-Proof Valves, as well as PM series of automotive waterproof and breathable valves, PF series of automotive waterproof and breathable valves, and other products, which have passed a large number of validations and can be used for a wide range of applications. The products have passed a large number of validations, and can help new energy vehicle battery packs and vehicles to meet the requirements of the “three strong standards”.

PUW explosion-proof valve significant advantages and features:

1.It can reach IP68 protection level, highly efficient dustproof and waterproof.

2.the breathable membrane adopts imported E-PTFE Waterproof Breathable Membrane material, the product performance is stable, durable and reliable.

3.patented structure design, waterproof, breathable, explosion-proof performance before leaving the factory 100% testing to ensure product quality.

4.when the pressure inside the battery pack reaches the explosion-proof valve explosion pressure value directly with the external straight-through, rapid venting, prevent or reduce the damage caused by high pressure in the battery box when the burst.

5.When the pressure inside the box is less than the burst pressure value, the pressure relief mechanism quickly reset, the product can continue to use.

6.the main material selection of aluminum alloy, waterproof sealing selection of high-temperature resistant flame retardant silicone rubber material, can ensure that the battery pack can pass the external fire test;

7.PUW independent research and development of patented products - PBA-E series products, PDA-E series of explosion-proof valves, with the detection of early warning function of the new explosion-proof valves, can be effective for the battery system thermal event alarm signal;

8.for 811 and other ternary lithium batteries, PUW patented products - PBA-G series of large exhaust volume anti-clogging explosion-proof valve can effectively prevent the system heat diffusion, so that the new energy power pack thermal runaway experiments in line with the requirements of the strong standards

9.PUW metal explosion-proof valve installation methods are internal flange type, external flange type, threaded variety; specifications size M20, M32, M40, 50, 60, 70 and other specifications, according to the characteristics of the customer's battery packs for customers to choose flexibly.

       The “three strong standards” for new energy vehicles and motors, electronic control, batteries and other related components of the three electric water, waterproof and power battery heat diffusion, system thermal runaway alarm, explosion-proof requirements are higher. Based on 10 years of research and development experience in the field of waterproof and breathable, PUW relies on the professional laboratory of Waterproof and Breathable Engineering and Technology Research Center and the professional R&D, manufacturing and service team to provide professional waterproof, breathable and explosion-proof products and solutions for the customers of new energy vehicles.
