The introduction of the automotive cable temperature rise test

Description: With the popularization 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. The following introduces the experimental results of cables during temperature rise testing:

Description: Temperature rise refers to the temperature rise caused by the heat generated by the current passing through the conductor during the charging process. When the electric vehicle charging cable is 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 cable, and even cause safety accidents. Therefore, it is of great significance to conduct temperature rise testing on electric vehicle charging cables.

Operation: Generally, in a laboratory or test site, an appropriate test environment is built, including temperature control equipment, power supply equipment, and test instruments. Select electric vehicle charging cable samples that meet the standard requirements as test objects.

Infrared thermometers and other equipment can be used to monitor the surface temperature of the cable in real time. According to the test data, the temperature rise value of the cable is calculated. The temperature rise calculation formula and standard requirements are usually used for evaluation to determine whether the temperature rise of the cable meets the specified limit range.
