Fast charge device for an electric or hybrid vehicle

A charging device for a hybrid or electric vehicle intended to be connected to an electricity distribution network and to the terminals of a battery of a hybrid or electric vehicle, the charging device comprising

• two charging cables for running independently of each other inside a vehicle,
• a connector comprising an input intended to be connected to a power cable itself connected to an electrical network and an output from which the charging cables extend;
• each of the two charging cables being intended to be connected to a terminal of the battery at one end of the cable, and at the other end to a terminal of the connector output,
• each charging cable comprising an electrical conductor and at least one insulating layer surrounding the electrical conductor,
• means for promoting heat dissipation, comprising at least one sheath arranged around the insulating layer, the sheath matching an assembly formed by the electrical conductor and the insulating layer,
• wherein said at least one sheath is in intimate unbonded contact with the insulating layer for avoiding air gaps between the sheath and the insulating layer for promoting heat dissipation from the charging device inside the vehicle and at the connector.
