New energy electric vehicles must be familiar to everyone. How much do you know about the wires and cables inside the vehicle? As for the thickness of vehicle high-voltage cable, in fact, the principle of household cable used is the same as that of other electric field. For example, comparing two kinds of high-voltage cables (divided into thickness and thickness) of two vehicles, it is concluded that the quality of high-voltage harness of "thin wire" is lower than that of “thick” high-voltage harness.
Of course, these are two kinds of high-voltage harnesses, which have different functions and cannot be directly compared. There are many specifications and models of vehicle high-voltage cables, such as 3mm ² -70mm ². For example, for electric vehicles, under nearly 400V high voltage, the high-voltage line used for 85KW motors is very different from the high-voltage line used for 6.6kw chargers - "thickness", that is, the difference in the cross-sectional area of copper wire, which is also obvious. Therefore, the vehicle high-voltage harness is assembled on different parts according to the power demand.
The high-voltage harness is connected to the spare parts on the vehicle, including drive motor, air conditioning system, on-board battery, etc. These applicable materials are also common materials according to the matching requirements of devices, such as 125 ℃ XLPE and 180 ℃ silica gel, which have high and low temperature resistance and tear resistance. The cable material is thermosetting material, and the wires and cables are soft and smooth, Cables of different specifications and models are made of shielded or unshielded materials.

With the investment of various regions and national household electrical appliance networks in the new energy industry, the construction of charging piles has developed rapidly all over the world. At the same time, the layout of hydrogenation stations closely related to hydrogen fuel cell vehicles is carried out in the new energy industry. In recent years, energy vehicles have become an economic growth point and an economic development engine concerned by the whole society. Global new energy vehicles have a certain share in various countries. The rapid development and increasing share of new energy vehicles can bring many opportunities to relevant supporting enterprises. Charging pile must be an important service fulcrum of new energy vehicles, which solves the problem of sustainable operation of new energy vehicles. Charging pile should expand rapidly with the increase of the number of new energy vehicles. In this context, charging pile has become a new economic growth point in the new energy industry. Nowadays, there is a trend in the field of new energy vehicles, and the policies promulgated by various countries all over the world continue to increase and give more support and encouragement. Under the new infrastructure empowerment, the charging pile is being recognized by all parties as a new foundation construction facility. The development of supporting industries related to the development of mainstream industries has finally become the consensus of the industry. Under the condition of demand and policy resonance, the supporting industry of new energy vehicles will usher in new development opportunities. Charging pile is the best track to enjoy the bonus of this policy opportunity. The vigorous development of charging pile in the future will drive the demand development of wire and cable industry, and new energy vehicles will also be greatly improved.

Electric vehicles rely on electricity to achieve vehicle driving, so after using electric vehicles for a period of time, the battery needs to be charged without electricity. Many consumers are very confused about this charging problem, because unlike traditional fuel vehicles, electric vehicles can drive without oil and refueling, However, it must be charged for a period of time before driving, which is why consumers don't know much about electric vehicles. When it comes to electric vehicle charging, they have to mention electric vehicle charging cables. Today I'll introduce the requirements of electric vehicle charging cables.
Its function requires that the electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electric energy. However, with the development of charging technology, in order to better complete the charging process, electric vehicles and charging piles need to communicate and automatically control when necessary. Therefore, the charging process puts forward higher requirements for the charging cable (EV cable). The charging cable not only needs the high-voltage cable (EV HV cable) to have the function of power transmission, but also needs to transfer the status and information of the vehicle and power battery to the charging pile for real-time interaction, and control the charging action under necessary conditions, so as to complete the charging process safely and reliably.
At present, the safety of electric vehicles has become the focus of the industry. In the charging and discharging process of electric vehicles, due to long time, high current intensity and high frequency of cable use, its safety should be highly valued. On the basis of ensuring good insulation performance, electric vehicle charging cable shall have high heat resistance and aging resistance. At the same time, it shall have good low smoke and flame retardant characteristics during combustion, so as to minimize loss and injury.
