The power battery system is inseparable from these engineering plastics
Author:
Lightweight and high efficiency have become indispensable themes in the rapid development of new energy vehicles in recent years. So how to lightweight? The answer is simple and not simple: use plastic.
As the core component of pure electric vehicles, the power battery is used to provide energy for the drive of electric vehicles, and all aspects of the performance of the power battery are closely related to the performance of the whole vehicle. Today we will take a look at what parts of the power battery can use plastic, and how should we choose the material?
First, performance requirements
1. Good chemical resistance, oil resistance, high and low temperature resistance;
2. Excellent mechanical properties, high flow, excellent processing performance;
3. Excellent surface properties and good dimensional stability;
4. It has good waterproof, moisture-proof, flame retardant and environmental protection and thermal conductivity function;
5. Good dielectric resistance, suitable for electrical places;
6. Superior weather resistance, good long-term performance, can be used for a long time in harsh environments
Second, material selection
1. Power battery holder
Power battery brackets require flame retardancy, dimensional stability, chemical resistance, high strength, and currently mainly use modified PPE, PPS, PC/ABS, etc
2. Power battery cover plate
Power battery cover plate requires flame retardant, dimensional stability, chemical resistance, high strength, currently mainly use modified PA6, PA66, etc.
