1. A contact element for an electric vehicle (EV) connector for connecting a charging wire to a connector interface on a vehicle side, comprising:
a front part defined on the contact element; and
at least one base defined on the contact element,
wherein the front part comprises walls having an inner side and an outer side that enclose a hollow chamber, the hollow chamber being configured to be partly fillable with a fluid during operation,
wherein the inner side of the walls is configured to draw the fluid from the hollow chamber via capillary structures formed within the walls,
wherein the front part of the contact element has a first base,
wherein the first base is solid,
wherein the first base is arranged on a second base, and
wherein the second base is fluid-cooled.
