Characteristics of automobile high-voltage cables and electric vehicle charging cables

The difference between automobile high-voltage wiring harness and electric vehicle charging cable: In electric vehicles, electric vehicle high-voltage cables are used to connect the charging port and the battery, inside the battery, and between the battery and the engine. Components, as well as battery storage devices, as a vehicle for power transmission inside the vehicle.

However, the charging cable is used to connect the EV charging unit to the charging infrastructure, thereby transferring power to the EV. The following description distinguishes the cable characteristics of the two products from the outside to the inside:

The difference between automotive high-voltage cables and charging cables is divided into 10 aspects: different laying, different heat resistance, different EMI requirements, different protection measures, different physical performance requirements, different size requirements, different color requirements, and number of cable cores Different, different international standards, etc.

Protective measures: The internal environment of the car is complex and harsh, and there are necessary protective measures around the high-voltage cable of the car; the charging cable has no protective measures and can withstand various shocks and ultraviolet radiation.

Physical performance requirements: Automobile high-voltage cables need to meet the wear-resistant requirements of automobiles; charging cables should meet the anti-extrusion requirements of mobile cables. Chemical resistance: Automotive high-voltage cables need to withstand various liquids that can be contacted on the car; charging cables need to withstand various liquids from the living environment outside the car.

Size requirements: The automotive high-voltage cable is limited by space and has strict size requirements. The smaller the size, the better; the charging cable has no size limit, and can be made thicker and larger.

Color requirements: Internationally, the color of automobile high-voltage cables is orange; however, there is no requirement for the color of charging cables.
