Compared with the new functions such as audio, screen, and leather seats, more and more people pay more attention to the configuration functions innovated and developed by car companies in terms of safety. In the reality of the increasing spontaneous combustion rate of new energy vehicles and the frequent news of intelligent driving out of control, who can enjoy those new functions that improve the driving experience without distraction?
In the market, in fact, some car companies and research institutions have paid attention to the safety of new energy vehicles, and have also launched some products that have received good feedback from car owners. For example, the passive safety device for spontaneous combustion of new energy vehicles, Shiweiqi fire shield, has been favored by more and more car companies and car owners.
What is the principle of the fire shield of SWYS?Is it useful to improve the safety of new energy vehicles?With these questions in mind, I did the following homework.
The danger of spontaneous combustion of new energy vehicles comes from the battery pack
New energy vehicles mainly use lithium-ion batteries as energy storage, which contain electrolytes and can conduct lithium ions. When a battery overheats or is impacted, the electrolyte rupture can cause a short circuit, allowing lithium ions to react rapidly with oxygen to produce heat and light energy. Moreover, the heat production during the combustion process leads to the decomposition of the electrolyte, the release of oxygen, and the formation of a self-oxygen combustion environment, which is difficult to extinguish.
To put it simply, the characteristics of spontaneous combustion of new energy vehicles are fast speed and large fire, so after the accident, the time left for the people in the car to run away is short, and the difficulty of rescue is high.
Shiweiqi fire shield to buy time for the occupants of the car to escape:
The material is flame retardant, resistant to flames up to 1200 degrees Celsius, and is installed under the seat. Take the seat apart and put it on top. In this way, in the event of spontaneous combustion of the battery pack, the SWIC Fire Shield can block the flames from entering the cockpit, thus providing valuable time for the occupants to escape. The installation can be completed in 2-5 hours, and there is no difference in the appearance of the vehicle before and after installation.
These "invisible" safety configurations, although not as intuitive as the exterior and interior of the car, can indeed play a role in protecting the lives of the people in the car at critical moments. Perhaps with the gradual popularization of the Schweiqi fire shield product, we will finally be able to relieve safety anxiety and see other functions of new energy vehicles in the spotlight.
