Overview of the Structure and Performance of Electric Vehicle Charging Cable

First of all, there are three major markets for electric vehicle charging cables in the world: Europe, America and China. The product specifications and models are IEC62893, EN50620 (IEC62893-3 is equivalent to EN50620), UL62, GB/T 33594, CQC1103-1105, DEKRA K175, TUV 2pfg 1908. Among them, the cable is composed of conductor, insulation, filling, wrapping, outer cover and sheath.

For example, the structural design differences between AC cable and DC cable in the new national standard are compared:

The new international AC charging cable is an AC charging cable certified by CQC and DEKRA, and its structural conductor material is bare copper Bare Copper; High temperature resistance, rated temperature between - 40 ℃ and 90 ℃, different from the above two product specifications and rated voltage of AC 450/750V; The data on insulation resistance is ≥ 0.037M Ω. km at 60 ℃ Apply with CQC1103-215; Min: Bending Radius: ≥ 6 * OD. The product specification is more resistant to pressure, oil and extrusion.

New International DC charging cable and AC charging cable are made of bare copper Bare Copper; High temperature resistance, rated temperature between - 40 ℃ and 90 ℃, different from the rated voltage of DC 1000V, the same as AC charging cable, the product material performance is also resistant to pressure, oil and extrusion.
