What are the flame retardant performance requirements for New Energy Battery Tray?
Publish Time: 2024-09-23
As a key component for carrying battery packs, the flame retardant performance of New Energy Battery Tray is crucial.
At present, there is no uniform absolute numerical requirement for the flame retardant performance of New Energy Battery Tray, but there are different considerations according to different application scenarios and standard specifications. Generally speaking, in the field of new energy vehicles, due to the particularity and extremely high safety requirements of the battery system, the tray needs to have good flame retardant performance to prevent the rapid spread of fire in the event of an accident such as a fire.
From the perspective of industry standards, some relevant standards may stipulate the flame retardant level of the tray. For example, it is required that the tray can self-extinguish within a certain period of time under specific combustion test conditions, and the combustion spread rate must be controlled at a low level. This is to ensure that when a vehicle crashes, short circuits, and other faults cause a fire, the tray can buy more time for passengers and rescuers.
From the perspective of materials, the sheet material used to make the tray usually needs to be added with flame retardants to improve its flame retardant performance. Different flame retardants and addition ratios will have a great impact on the flame retardant effect of the tray. The ideal flame retardant performance should make the tray not easy to burn when facing open flames or high temperatures, and even if it burns, it can quickly extinguish itself, and will not produce a large amount of toxic smoke and harmful gases.
In addition, the structural design of the tray will also have a certain impact on the flame retardant performance. A reasonable structure can prevent the spread of flames to a certain extent, such as the use of fire isolation grooves, reinforcement ribs and other designs. At the same time, the installation method of the tray and the battery pack and other components should also consider the flame retardant requirements to avoid the increase of fire risks due to improper installation.
In short, the flame retardant performance requirements of the New Energy Battery Tray are a comprehensive indicator that needs to be considered and controlled from multiple aspects such as material selection, structural design, and standard specifications. Only by meeting certain flame retardant performance requirements can the safety and reliability of new energy vehicles during use be ensured.
