1. An electric vehicle charging assembly comprising:
an electric vehicle charging cable comprising: a grounding unit; at least one communication unit; a pair of power units each including a conductor and an insulating layer covering the conductor; a cooling unit configured to cool the conductor and included in the conductor of each of the power units, the cooling unit including a cooling tube and a cooling channel which is included in the cooling tube and in which a cooling fluid flows; and a collection unit including a collection tube in which a collection channel is provided to collect the cooling fluid supplied through the cooling unit; and
an electric vehicle charging connector comprising: a pair of power terminals each including a connecting part to be connected to a connector connection unit of an electric vehicle and a conductor connection part into which a conductor of the electric vehicle charging cable is inserted to be connected to the conductor connection part; and a cooling chamber configured to accommodate the conductor connection part of the power terminal, cool heat generated in the conductor connection part by using the cooling fluid flowing through the cooling unit, and collect the cooling fluid by the collection unit,
wherein the conductor connection part of the power terminal and the stripped conductor of the electric vehicle charging cable are directly exposed to the cooling fluid, which is collected by the cooling unit and supplied to the collection unit, in the cooling chamber.
