Introduction of Flame Retardant Materials for Main Components of New Energy Vehicles

There are many parts of the car that use flame retardant materials, especially for new energy vehicles. The application of flame retardant materials is more extensive. Especially in charging piles and battery parts, plastic parts are required to be flame retardant.

When it comes to new energy vehicles, this is one of the hottest areas in recent years. For material people, the most concerned may be the application of new materials on the car.

Compared with traditional cars, new energy vehicles have great differences in material selection. For example, battery modules, charging piles, charging guns, etc. must be made of flame retardant materials. Let’s look at them together. Look!

Application of Flame Retardant Material on Charging Pile 1 Charging Gun As an electric vehicle charging connector, the charging gun is a “bridge” connecting charging facilities such as charging piles and electric vehicles. The quality of the charging gun directly affects the charging performance and safety. The material requirements of the charging gun are relatively high. Common materials are: PBT+GF, PA+GF, weather resistant PC, etc.

Charge gun material requirements

The material of the socket plug is mainly PBT-GF25 FR/PBT-GF30 FR, PA66-GF25 FR/PA66-GF30 FR and PA66-GF25 FR/PA66-GF30 FR (Free of halogen).

Socket plug material requirements 2 Shell Charging pile shell is generally made of flame retardant PC material, material characteristics: halogen-free flame retardant, high surface gloss, excellent electrical insulation properties, excellent mechanical properties.

4 Battery Module Housing The battery pack housing can be generally made of steel, aluminum alloy, SMC composite material, carbon fiber reinforced composite material, LGF-PP, PBT/ASA, etc.

Due to its good comprehensive performance, the plastic shell is the main development direction of the current power battery housing materials. The series of lithium batteries produced by Leitian, Huanyu, AVIC Lithium, Haiba, Qingshan and other companies are all plastic housings. It is reported that in the power battery standard, the corresponding flame retardant requirements are put forward for the battery case body, and now more and more enterprises are beginning to use flame retardant plastics as power batteries.

5 Automotive Connectors Basic requirements for connector materials: heat resistant and flame retardant! The connector contacts are metal, the number of insertions and removals is high, the material is required to have good flame retardancy, heat resistance, and avoid fire. Currently, the commonly used materials for connectors are PBT, PPS, PA, PPE, PET, and the like.

6 Electric vehicle charging line Unlike traditional wire and cable, car charging line has high requirements for materials because of its special application environment. Because the charging process of electric vehicles is short, the current intensity is high, and the frequency of use is high, the material is required to have high temperature resistance and aging resistance while ensuring good insulation, and has halogen-free flame retardant and low smoke during combustion. density.
