How to choose the cable of charging post of new energy vehicle

Mar 01, 2020

New energy and green travel have become a new way of life, and more and more charging piles appear in life, so the cable of standard electric vehicle DC (AC) charging pile has become the “heart” of charging pile.
Due to the strong development and support of the state, according to statistics: before 2015, China had 497000 new energy vehicles, plus 62663 sold in the first quarter of 2016, totaling 560000. The corresponding charging infrastructure is as follows: by the end of 2015, more than 3600 charging and replacement power stations and 49000 public charging piles have been built in China. In the future, more and more charging piles will be used. Therefore, the standard electric vehicle DC (AC) charging pile cable 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 is three-phase four wire AC380V ± 15%, with a frequency of 50Hz, and the output is adjustable DC, which directly charges the power battery of the electric vehicle. It can realize the requirements of fast charging, while the standard electric vehicle AC charging pile is commonly known as “slow charging”. The AC charging pile only provides power output and has no charging function. It needs to connect the vehicle charger to charge the electric vehicle, which is the requirement of large amount of charging pile cable.
Dru cable is mainly produced by special cable, so its standard electric vehicle DC charging pile cable has very high performance, which is mainly used in charging pile system, floor type charging pile and wall mounted charging pile, including voltage of 1KV (DC), test voltage of 6000V / min (DC), fixed laying: 4 × cable outer diameter, mobile installation: 7.5 × cable outer diameter or smaller temperature range, Fixed laying: – 50 ℃~ 90 ℃, mobile installation: – 40 ℃~ 90 ℃, oil resistance: very good, chemical resistance, acid, alkali resistance, solvent resistance and various hydraulic oils, weather resistance: UV resistance, excellent sunlight aging performance, suitable for outdoor use. Flame retardant characteristics: in accordance with IEC. It adopts special structure and can be customized.
Application characteristics: 1. The signal control and transmission network system of the cable for voltage, current, etc. during the charging process has the characteristics of high voltage resistance, high temperature resistance, electromagnetic interference resistance, stable signal transmission, over 10000 times of anti deflection, over 50000 times of wear resistance, over 50000 times of wear resistance, oil resistance, water resistance, acid and alkali resistance, UV resistance, etc.
2. The concentricity of the product is good, up to more than 80%, which makes the high voltage resistance of the cable stable and reliable.
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, which is very convenient for vehicle wiring.
4. The rated temperature of the product is 125 ℃, which is a great technical progress and promotion for the adoption of one-time molding soft insulation material, and it is very important to ensure the flexibility of the cable and improve the current carrying capacity of the cable.
