Abstract: A contact element arrangement for an electric vehicle (EV) connector configured to connect a charging wire to a connector interface on vehicle-side includes a contact element and a heat pipe. The contact element comprises a base portion to which a charging wire is connected and a contact portion, which is adapted to contact a counter contact element on a vehicle side. The base portion is cooled by a fluid, and the heat pipe extends from the contact portion to the base portion and is configured to carry heat from the contact portion to the base portion.

Abstract: An electric vehicle charging system includes a charging connector configured to receive a charging cable provided with electrical charging wires. The charging cable and/or the charging connector provide a flow path for guiding a liquid coolant, cooling the charging cable and/or the charging connector, and a thermal management unit for cooling the liquid coolant, the thermal management unit being fluidly connected to the flow path. The liquid coolant is an ionizable coolant, wherein a deionizing unit is provided and fluidly connected to the flow path for deionizing the liquid coolant to decrease its conductivity.
