Application and Characteristics of Electric Vehicle Cables

Since 2018, the trend of the new energy vehicle market has shown a good start. In January, sales of new energy passenger vehicles reached 31,638 units, a year-on-year increase of 483%. From sales data, market conditions are very good; from the perspective of industrial layout, China's automobile investment in 2017 exceeded 450 billion, and the layout and investment in 2018 far surpassed that of last year; from the perspective of industrial policies, the main policies introduced are favorable for the development of new energy vehicles. From the dimensions of the market, capital, and policies, the development of new energy vehicles has entered a stage of intense competition.

Understanding electric vehicle cables

The production and application of new energy vehicles have significant advantages in environmental and noise aspects. Electric vehicle cables have emerged, immediately bringing various doubts. Electric vehicle cables are used to connect the charging gun and charging infrastructure to transfer electric vehicles, and are equipped with a certain number of signal lines, control lines, and power auxiliary lines to ensure accurate control of the entire charging process and correct and safe operation.

Application scope of electric vehicle cables

Electric vehicle cables can be used indoors or outdoors. When used outdoors, electric vehicle cables should withstand cold, sunlight, rain, and vehicle oil corrosion, which requires cables to have special properties such as anti-ultraviolet, ozone resistance, high and low-temperature resistance, and chemical corrosion resistance. During use, electric vehicle cables will be frequently stretched, bent, or crushed by electric vehicles, which also requires electric vehicle cables to meet special mechanical performance requirements, such as bending, dropping, and vehicle rolling tests.

Features of electric vehicle cables

• During the charging process, the electric vehicle cable has high voltage resistance, high temperature resistance, electromagnetic interference resistance, stable signal transmission, more than 10,000 bend resistance, and more than 5,000 wear resistance. Electric vehicle cables have characteristics such as oil resistance, water resistance, acid and alkali resistance, and UV resistance.

• The concentricity is good, reaching 80% or more, making the high voltage resistance of electric vehicle cables stable and reliable.
  

• Electric vehicle cables are small and have a bend radius of 4D, which is easy to use for narrow space wiring. Electric vehicle cables have high flexibility and are very convenient to use for vehicle wiring.
  

• The rated temperature of electric vehicle cables is 125℃, which is a significant technical progress and improvement for disposable molded soft insulation materials, which is very important for ensuring the flexibility of the cable and improving the cable's current-carrying capacity.
