Abstract: In one aspect, a charging station is provided. The charging station includes a controller, a direct current (DC) power source configured to provide a charging power for charging an electric vehicle, a charging cable with a connector configured to electrically contact a vehicle inlet of the electric vehicle, a connector holder with a station inlet configured to electrically contact the connector when the connector is inserted into the connector holder, and a contact resistance sensor electrically connected to the station inlet. The contact resistance sensor configured to measure a resistance of at least one electrical contact formed between the connector and the station inlet. The controller is configured to cause the DC power source to provide a measuring power while the connector is inserted into the connector holder so that a measuring current flows between the connector and the station inlet, and receive a resistance value from the resistance sensor.

Abstract: A fluid channel assembly for a connector of a charging gun for an electric vehicle is provided. The fluid channel assembly includes a fluid channel network for cooling a contact pin of the charging gun. The fluid channel network is arranged around the contact pin and is in direct or indirect contact with the contact pin. Further, the fluid channel assembly includes a fluid inlet connected to the fluid channel network via a first single fluid transfer channel. The fluid inlet is configured to receive a coolant through a charging cable and to inject the coolant into the fluid channel network. A fluid outlet connected to the fluid channel network via a second single fluid transfer channel is provided. The fluid outlet is configured to receive the coolant from the fluid channel network and to inject the coolant into the charging cable.

Abstract: A fluid channel assembly for an Electric Vehicle (EV) charging gun includes a fluid channel network for cooling a contact pin of the EV charging gun, a fluid inlet connected to the fluid channel network and configured to receive a coolant through an EV charging cable and to inject the coolant to the fluid channel network, and at least one fluid outlet connected to the fluid channel network, and configured to receive a coolant from the fluid channel network and to inject the coolant to the EV charging cable. The fluid channel network is configured to be arranged around the contact pin in direct or indirect contact with the contact pin.

Abstract: An electrical insulation mixture for forming a layer on a conductor surface is provided. The mixture includes an UV curable thermoset resin and a filler. The filler includes UV transparent platelets made of a platelet material. UV transparency is given for light in a wavelength range between 300 and 420 nm. Furthermore, a method for electrically insulating a metallic conductor is provided. The method includes obtaining the electrical insulation mixture, forming a jacketing on a surface of the metallic conductor using the mixture thus obtained, and exposing the mixture to ultraviolet radiation to cure the mixture, thus forming, from the jacketing, an electrical insulation layer on the surface of the metallic conductor. A metallic conductor with an electrical insulation layer can be obtained by using the electrical insulation mixture.
