What Are the Usage Characteristics of Electric Vehicle Cables?

More and more new energy vehicles are being used, which have great advantages in terms of environmental protection, noise reduction, and other aspects. However, charging has always been a problem. What kind of cable should be used for the charging pile of electric vehicle cables?

Current situation of new energy vehicles

New energy vehicle battery life and charging pile construction and other issues cannot be quickly laid out and put into the market. The development of new energy vehicles will enter a transitional period of hybrid vehicle models. New energy vehicle cables also need to meet the basic performance requirements of general fuel road vehicles, such as oil resistance, excellent electrical performance, excellent high and low temperature performance, mechanical performance, heat resistance, etc., and also meet special requirements for electric vehicle cables, such as high load current capability.

Electric vehicle cables are currently the dedicated cables for new energy vehicles and an important part of electrical transmission. They are used to connect electric vehicle charging devices with charging infrastructure. Due to the environmental factors of its use, high performance requirements are imposed on the cable, including strength, aging resistance, high temperature pressure, thermal shock, low-temperature winding and tensile resistance, acid and alkali resistance, hydrolysis resistance, tear resistance, and halogen assessment.

Application scope of electric vehicle cables

The electric vehicle cables of the charging pile can be used indoors or outdoors. When used outdoors, the electric vehicle cables of the charging pile should be able to resist cold, sunlight, rainwater, and automotive oil substances, which require the cable to have special properties such as anti-ultraviolet, ozone resistance, high and low-temperature resistance, and chemical corrosion resistance that are suitable for use in different environments. During the use of the charging pile, the electric vehicle cable will be subjected to frequent stretching and bending or external mechanical damage caused by the electric vehicle, which also requires the charging pile cable to meet special mechanical performance requirements such as bending and vehicle crushing tests.

Characteristics of electric vehicle cables

• The electric vehicle cable has characteristics such as high voltage resistance, high temperature resistance, anti-electromagnetic interference, stable signal transmission, anti-creep bending for more than 10,000 times, wear resistance of more than 50,000 times, oil resistance, water resistance, acid and alkaline resistance, UV resistance, etc.

• Good concentricity, up to more than 80%, making the cable's high voltage resistance performance stable and reliable.
  

• The small bending radius is 4D, which is convenient for narrow space turning and wiring. Electric vehicle cables should have high flexibility characteristics, which is very convenient for vehicle wiring.
  

• Rated temperature of 125℃. This is a great technological advancement and improvement for using once-molded soft insulation materials. It is important to ensure the cable's flexibility and improve its current-carrying capacity.
