AI Technical Summary

Problems solved by technology

[0004] Electric vehicles need to be equipped with large-capacity batteries, which need to be charged after the batteries are exhausted. In order to improve the practicability and convenience of electric vehicles, fast charging technology should be used to charge the battery of the car, so as to shorten the charging time of the battery. Fast charging technology The charging power of the battery is relatively large, so there are special requirements for the charging cable. Different fast technical standards have different performance requirements for the cable, but the charging cable for fast charging generally requires the cable to be able to withstand the heating problem caused by high power.

At present, the high temperature resistance of cables on the market is relatively poor, and the cable sheath will become soft under long-term high-power use, and the mechanical properties of the cable will deteriorate.

In addition, due to the frequent plugging and unplugging of the charging cable, the cable is required to have good tensile strength and flexibility. The cables currently on the market cannot achieve a balance in the above multiple properties.

[0005] In order to strengthen safety measures and improve production efficiency, the existing cable materials are insufficient in flame retardancy and anti-interference performance, and need to have the characteristics of easy processing, chemical corrosion resistance, high temperature resistance, fatigue resistance, and good chemical stability.
