With the popularity of electric vehicles and the construction of charging facilities, the performance and safety of electric vehicle charging cables have become the focus of attention. Among them, temperature rise is one of the important indicators for evaluating the performance of charging cables. This article will introduce the temperature rise test of electric vehicle charging cables and discuss its significance and testing methods.

Temperature rise refers to the increase in temperature of the cable due to the heat generated by the current passing through the conductor during the charging process. When electric vehicle charging cables are charged at high power, due to the large current, a certain amount of heat will be generated. If the temperature rise is too high, it may affect the performance and safety of the cables, and even cause safety accidents. Therefore, temperature rise testing of electric vehicle charging cables is of great significance.

Generally, an appropriate test environment is set up in a laboratory or test site, including temperature control equipment, power supply equipment, and test instruments. Select electric vehicle charging cable samples that meet the standard requirements as test objects. The selection of samples should take into account cables of different powers and specifications to cover different charging needs. Set the appropriate test current according to standard requirements or actual conditions. The test current should comply with the rated current of the charging equipment and actual usage.
