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 cable
