A contact element for an electric vehicle (EV) connector that is configured to connect a charging wire to a connector interface on a vehicle side includes a front part and at least one base. The front part comprises walls having an inner and an outer side that enclose a hollow chamber, which is partly filled with a fluid, and the inner side of the walls are designed having a capillary structure.

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.

Contact element arrangement for an EV connector

The present invention relates to an electric vehicle charging connector () comprising an external enclosure () configured to receive and guide a cable () from a back () end to a front end () of the electric vehicle charging connector () and to enclose a compartment () in the front end accommodating power contacts, wherein the electric vehicle charging connector () further comprises an active cooling element ().

A system and method are provided for storing electric energy in the form of thermal energy. A thermoelectric energy storage system includes a working fluid circuit for circulating a working fluid through a heat exchanger, and a thermal storage medium circuit for circulating a thermal storage medium. The thermal storage medium circuit includes at least one hot storage tank, an intermediate temperature storage tank, and a cold storage tank connected together via the heat exchanger. A proportion of the storage medium is redirected to or from the intermediate storage tank from or to the hot or cold storage tank, joining another proportion which flows directly between the cold and hot storage tank.

An exemplary system and method for storing and retrieving energy in a thermoelectric energy storage system is disclosed. The thermoelectric energy storage system includes a working fluid that is circulated through a first and second heat exchanger, and a thermal storage medium that is circulated through the first heat exchanger. The second heat exchanger is in connection with a first thermal bath during a charging cycle and with a second thermal bath during a discharging cycle. In this way roundtrip efficiency is improved through minimizing the temperature difference between the first thermal bath and the hot storage tank during charging, and maximizing the temperature difference between the second thermal bath and the hot storage tank during discharging.
