How to choose charging pile cable for new energy vehicles?

by:AAA     2020-03-05
New energy and green travel have become a new way of life, and more and more charging piles appear in life, so the standard electric vehicle DC (Communication) The charging pile cable has become the 'heart' of the charging pile '. Due to the vigorous development and support of the state, according to statistics: before 2015, China retained 49 new energy vehicles. 70 thousand vehicles, plus 62663 vehicles sold in first quarter of 2016, totaling 56 thousand vehicles. The corresponding charging infrastructure status is as follows: by the end of 2015, more than 3600 charging stations and public charging piles had been built nationwide. 90 thousand. In the future development, charging piles will be used more and more. Therefore, standard electric vehicle DC (Communication) Charging pile cables will become a major mainstream in the cable industry. The standard electric vehicle DC charging pile is commonly known as 'Fast charging '. During the charging process, the input voltage of the DC charging pile adopts three-phase four-wire ac380v±15%, the frequency is 50Hz, and the output is adjustable direct current, directly charge the power battery of electric vehicles. Fast charging requirements can be realized; While the AC charging pile of standard electric vehicle is commonly known as 'slow charging ', the AC charging pile only provides power output, and has no charging function. It needs to be connected to the on-board charger to charge the electric vehicle, this is the requirement of large quantity of charging pile cables. De Ru cable is mainly produced by special cables, so its standard DC charging pile cable for electric vehicles has high performance and is mainly used in charging pile system, floor-standing charging pile and wall-hanging charging pile, of which the voltage is 1KV (DC), Test voltage 6000 V/min (DC) , Fixed laying: 4× cable outer diameter, mobile installation: 7. 5 x cable outer diameter or smaller temperature range, fixed laying :-50 ℃ ~ 90 ℃, mobile installation :- 40 ℃ ~ 90 ℃, oil resistance: very good, chemical resistance, acid, alkali, solvent and various hydraulic oil performance is excellent, weather resistance: UV resistance, sunlight aging performance is excellent, suitable for outdoor use. Flame retardant characteristics: conforming to IEC. Special structure is adopted, and specifications can be customized. Usage characteristics: 1. The signal control and transmission network system of this cable for voltage, current, etc. during charging has high voltage resistance, high temperature resistance, electromagnetic interference resistance and stable signal transmission, anti-folding more than 10000 times, wear-resistant more than 50000 times, wear-resistant more than 50000 times, oil-resistant, waterproof, acid and alkali resistant, UV resistant and other characteristics. 2. The product has good concentricity, which can reach more than 80%, making the cable stable and reliable in high voltage resistance. 3. The minimum bending of the product is 4D, which is convenient for use between corner wiring in narrow space. The product has high flexibility and is very convenient for vehicle wiring. 4. The rated temperature of the product is 125 ℃, which is a great technological progress and improvement for the soft insulation material formed once, it is very important to ensure the flexible performance of the cable and improve the current carrying capacity of the cable.
