A kind of electric vehicle charging cable and preparation method thereof

Abstract

A charging cable for an electric vehicle and a preparation method therefor. The charging cable sequentially comprises, from inside to outside, an inner cable core (1), a filling material (2), a wrapping belt (3), a cellular belt material (4), and an outer sheath (5). The inner cable core (1) comprises a power wire (11), a grounding wire (12), a signal transmission control wire (14), and an auxiliary power wire (13), which respectively comprise copper conductors (111, 121, 131, 141) and insulating layers (112, 122, 132, 142) wrapping the copper conductors (111, 121, 131, 141). The signal transmission control wire (14) further comprises: a nylon rope (143) filled on the corresponding insulating layer (142), a successively-wound aluminum plastic composite belt layer (144), a weaving layer (145) wrapping the aluminum plastic composite belt layer (144), and an inner sheath (146) extruded onto the weaving layer (145). The charging cable resolves the technical problems of low charging speed of a conventional charging cable for an electric vehicle and easy damage to the charging cable due to frequent dragging, not only can quickly charge the electric vehicle, but also has the characteristics of warp resistance, crushing resistance, and high tensile strength.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a twist-resistant, rolling-resistant, and tensile electric vehicle fast charging cable and a preparation method thereof. Background technique [0002] With the development of society, the global energy crisis is intensifying, oil resources are becoming increasingly depleted, air pollution and global warming are becoming more and more serious, and cars, as an indispensable means of transportation for people to travel, usually rely on burning oil to drive, which will aggravate energy and environment. crisis. In this regard, the automobile industry has launched new energy electric vehicles, which can avoid or reduce oil burning, which is conducive to promoting environmental protection and alleviating the shortage crisis of traditional energy sources, and has broad market development prospects. As an indispensable charging accessory for electric vehicles, electric vehicle charg...

AI Technical Summary

Problems solved by technology

On the other hand, as new energy electric vehicles (including environmentally friendly and energy-saving electric vehicles and hybrid electric vehicles) are more and more widely used, more and more charging cables are used for charging stations. When charging many electric vehicles, charging The cable will be dragged frequently, which will easily cause damage and affect the service life of the cable

[0004] It can be seen that there are technical problems in the prior art that the charging speed of the electric vehicle charging cable is not fast, and it is easily damaged after being frequently dragged
