Electric automobile rapid charging cable and preparation method thereof

Abstract

The invention discloses an electric automobile rapid charging cable and preparation method thereof, solving the technical problem that a current electric vehicle charging cable in the fast charge generates the electromagnetic radiation to interfere charging control. The charging cable includes power supply lines, a ground wire, signal transmission control lines and auxiliary power supply lines that respectively comprise copper conductors and insulating layers coating the outside of the copper conductors, and the signal transmission control lines and the ground wire are adjacent. Each signal transmission control line further includes nylon wire ropes filling the corresponding insulating layer, successively winding plastic-aluminum composite belt layers, a braiding layer wrapping the plastic-aluminum composite belt layers, a conducting resin layer coating the braiding layer, and an inner sheath extruding on the conducting resin layer. The charging cable further includes a PP rope filling a line group formed by the power supply lines, the ground wire, the auxiliary power supply lines and the signal transmission controls, successively lapping wrapping layers, and an outer sheath compacting on the wrapping layer. The electric automobile rapid charging cable can carry out anti-electromagnetic radiation while rapidly charging an electric automobile.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an electric vehicle fast charging cable resistant to electromagnetic radiation and a preparation method thereof. Background technique [0002] At present, the development of the electric vehicle industry is restricted by the battery life of the vehicle. In order to facilitate users to charge electric vehicles immediately when needed, relevant electric power departments have set up charging piles on the roadside. In order to meet the charging needs of electric vehicles, existing charging piles need to charge electric vehicles for a long time, usually for 6 to 8 hours. Long charging time is an important factor hindering the rapid development of electric vehicles. The development of fast charging piles is a top priority, and the development of charging cables suitable for fast charging systems is an important link in the realization of fast charging systems. [0003] The key ...

AI Technical Summary

Problems solved by technology

However, the differential mode interference current and common mode interference current on the charging cable can be directly conducted into the circuit module or other equipment of the electronic equipment (such as charging pile) through the cable, and can also generate electromagnetic fields in space to form radiation interference, causing equipment command errors Judgment, wrong operation

For example, an electric vehicle has been fully charged, but due to electromagnetic radiation interference, the charging pile still shows that it is not fully charged, resulting in overcharging of the electric vehicle
