PUW power battery explosion-proof valve helps new energy electric vehicles meet the national three strong standards
(Summary description)
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 China's new energy vehicles has driven strong demand for power batteries. But at the same time, electric vehicle battery fires and burning accidents happen frequently, which is tantamount to holding an untimed bomb, and life safety is always threatened. It has triggered people's concerns about the safety of new energy vehicles and their batteries.
Electric car catches fire
On May 12, the Ministry of Industry and Information Technology organized three mandatory requirements: GB 18384-2020 "Safety Requirements for Electric Vehicles", GB38032-2020 "Safety Requirements for Electric Buses" and GB 38031-2020 "Safety Requirements for Power Batteries for Electric Vehicles" National standards (hereinafter referred to as the "three strong standards") are approved and issued by the State Administration for Market Regulation and the National Standardization Administration, and will be implemented on January 1, 2021.
In response to the "three strong standards", as a professional design and development of new energy vehicle three-electric waterproof and breathable valve, PUW Puwei, designed and developed the PBA series two-way breathable waterproof and breathable explosion-proof valve, PDA series one-way breathable explosion-proof valve, and PM The series of automotive-specific waterproof and breathable valves, the PF series of automotive-specific oil-proof, waterproof, and breathable valves have passed a large number of verifications, which can help new energy vehicle battery packs and vehicles meet the "three strong standards" requirements.
Significant advantages and characteristics of PUW explosion-proof valve:
1. It can reach IP68 protection level, which is highly dustproof and waterproof.
2. The breathable membrane adopts imported E-PTFE waterproof and breathable membrane material, with stable product performance, durability and high reliability.
3. Patented structure design, waterproof, breathable, and explosion-proof performance are 100% tested before leaving the factory to ensure product quality.
4. When the pressure in the battery pack reaches the explosion pressure value of the explosion-proof valve, it is directly connected to the outside and quickly vents to prevent or reduce the damage caused by the high pressure in the battery box during blasting.
5. When the pressure in the box is less than the burst pressure value, the pressure relief mechanism is quickly reset and the product can continue to be used.
6. The main material is aluminum alloy, and the high temperature resistant flame-retardant silicon rubber material is selected for the waterproof seal, which can ensure that the battery pack can pass the external fire test;
7. PUW independently researched and developed patented products-PBA-E series products, PDA-E series explosion-proof valves, new explosion-proof valves with detection and early warning functions, which can effectively alarm signals for thermal events in the battery system;
8. For ternary lithium batteries such as 811, the PUW patented product-PBA-G series large displacement anti-clogging explosion-proof valve can effectively prevent system heat diffusion and make the thermal runaway experiment of new energy power battery packs meet the requirements of strong standards
9. PUW metal explosion-proof valve installation methods include internal flange type, external flange type, and various thread types; specifications include M20, M32, M40, 50, 60, 70 and other specifications, which can be provided to customers according to the characteristics of customer battery packs Flexible selection.
The "Three Strong Standards" have higher requirements for new energy vehicles and motors, electric control, battery three-electricity and other related components for water, water resistance and thermal diffusion of power batteries, system thermal runaway alarms, and explosion-proof requirements. Professional things, professional people do it, PUW Puwei based on 10 years of research and development experience in the field of waterproof and breathable, relying on professional waterproof and breathable engineering technology research center laboratory, and professional R & D, manufacturing and service team, for the majority of new energy vehicles Customers provide professional waterproof, breathable and explosion-proof products and solutions.
