During the process of high-power fast charging of electric vehicles, large current will pass through the charging cable, leading to a lot of heat generation. Excessive heat accumulation will increase the temperature, shortening the cable life, and even leading to physical damage to the cable and arousing safety accidents. In this paper, the thermal process of charging cable during charging was numerically studied. It was found that the safety of the cable was reliable when the charging current was less than the nominal value. When the charging power and current are further increased, the temperature at the insulation layer of the cable will exceed the safety upper limit and the cable cannot work safely, indicating additional auxiliary heat dissipation measures must be taken.
