Abstract
An electric vehicle (EV) charging connector comprises a charging cable. The charging cable comprises charging lines configured to carry charging current and at least one air tube. The contact element is connected to the charging cable and is the galvanic contact interface to a car inlet; and each air tube is configured to lead an air stream directly to the hot portion of the EV charging connector such that air of the air stream flows around the hot portion.
Claims11
An electric Vehicle (EV) charging connector, comprising:
- a charging cable that includes charging lines, which are configured to carry charging current, and at least one air tube;
- a contact element connected to the charging cable, the contact element being a galvanic contact interface to a car inlet;
- wherein the contact element is a part of a hot portion of the EV charging connector;
- a passive cooling device connected to the contact element, wherein the passive cooling device is a further part of the hot portion of the EV charging connector;
- and
- wherein the least one air tube is configured to lead an air stream directly to the hot portion of the EV charging connector for cooling the hot portion such that air of the air stream flows at least partially around the hot portion.
An electric vehicle (EV) charging station, comprising:
- an air stream generator;
- and
- a charging cable, the charging cable comprising:
- a line configured to carry charging current to an EV charging connector;
- and
- an air tube;
- wherein the air stream generator is configured to generate an air stream in the air tube and to lead the air stream directly to a hot portion of an EV charging connector for cooling the hot portion such that air of the air stream flows around the hot portion and
- a control unit that receives temperature data from the EV charging connector and controls the air stream dependent on the temperature.
A method for cooling parts of an electric vehicle (EV) charging connector, comprising:
- providing an EV charging connector comprising a charging cable, wherein the charging cable comprises charging lines configured to carry charging current, and a contact element connected to the charging cable, the contact element being the galvanic contact interface to a car inlet;
- wherein the contact element is a part of a hot portion of the EV charging connector;
- and at least one air tube, each configured to lead an air stream to the hot portion of the connector, wherein the EV charging connector further comprises a passive cooling device connected to the contact element, and the passive cooling device is a part of the hot portion of the EV charging connector, and
- leading an air stream directly to the hot portion of the EV charging connector for cooling the hot portion such that air of the air stream flows around the hot portion.
