Problems solved by technology
Also, both solutions are considered poor in terms of reliability due to the very limited material temperature reached during normal operation
[0007] Further still, in existing solutions, coolant flow can be easily blocked by internal blockages or broken pipes as examples
This can represent a safety issue, especially during a charging session, as thermal runaway can be extremely fast and the interlock system in the charging station may only intervene with a certain delay

Embodiment Construction
[0047] figure 1 with figure 2 A high-current charging cable 1 for charging an electric vehicle according to a preferred embodiment is shown in each case in a cross-sectional view. The cable 1 comprises one high current center conductor 2 serving as a ground, the high current center conductor 2 comprising a center conductor 3 extending in a longitudinal direction perpendicular to the layers and a center conductor insulation 4 surrounding the center conductor 3 . Although not shown, the central conductor 2 may be provided as non-insulated. Center conductor 2 includes 25mm 2 The cross-section, while the central wire insulation 3 includes a thickness of 0.5mm to 2mm.
[0048] The high-current charging cable 1 also includes six high-current power conductors 5, each of which is configured to conduct positive direct current DC and negative DC. Six high-current power conductors 5 each extend parallel to the center conductor 2 and are arranged around the center conductor 2 so as t...
