Study on Temperature Shock Tests Performed on Charging Cables for Electric Vehicles

Abstract The cables used for electric vehicle charging are subjected to various stresses and interventions during operation or storage. It is taken into account that these cables are stored in a certain form, usually coiled, after which they are unwound, stretched and, while being subjected to an electromagnetic field, are in the open air. This can mean high or low temperatures and various other environmental actions. During handling and actual electrical charging, various situations arise in which shock loads may occur. One reason would be the stress caused by shock traction by the user. Another cause can be the fall of foreign bodies during the electric charging operation. There can also be an accidental passage over the cable with the car wheel. If all these shock stresses are superimposed and with high temperatures, these cables can be taken out of use. In this paper, the results of shock tests of two types of cables, at high temperatures, are presented.
