Fast charge device for an electric or hybrid vehicle
The invention concerns a charging device for a hybrid or electric vehicle intended to be connected to an electricity distribution network ( 2 ) on the one hand, and to the terminals of the battery ( 10 ) of a hybrid or electric vehicle on the other hand, the device comprising two charging cables ( 61, 62 ) suitable for running, independently of each other, inside the vehicle, each being intended to be connected to a terminal of the battery, each charging cable ( 61, 62 ) comprising an electrical conductor ( 8 ) and at least one insulating layer ( 9 ) surrounding the electrical conductor ( 8 ), each charging cable further comprising a protective device (G) consisting of at least once sheath (G 1 , G 2 ) disposed around the insulating layer and matching the assembly formed by the electrical conductor ( 8 ) and the actuating layer ( 9 ).
1 . 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.
2 . The charging device according to claim 1 , wherein said at least one sheath is disposed by an extrusion or co-extrusion method so as to be in intimate unbonded contact with the insulating layer on which the sheath is disposed.
3 . The charging device according to claim 1 , wherein said at least one sheath is a heat-shrinkable sheath so as to be in intimate unbonded contact with the layer on which the sheath is disposed.
4 . The charging device according to claim 1 , wherein the protection device comprises a first sheath in contact with the insulating layer.
5 . The charging device according to claim 4 , wherein the protection device further comprises a second sheath in contact with the first sheath.
6 . The charging device according to claim 5 , wherein the first sheath and the second sheath have identical radial thickness.
7 . The charging device according to claim 6 , wherein the first sheath and the second sheath are made of identical material.
8 . The charging device according to claim 4 , wherein the sheath is made of a material chosen among thermoplastic polymers.
9 . A charging assembly for a hybrid or electric vehicle comprising the charging device according to claim 1 and a power cable intended to be connected to an electricity distribution network.
10 . The charging device according to claim 6 , wherein the first sheath and the second sheath are made of different material.
11 . The charging device according to claim 8 , wherein the thermoplastic polymer is polyvinyl chloride.
12 . The charging device according to claim 8 , wherein the thermoplastic polymer is cross linked polyethylene.
13 . The charging device according to claim 5 , wherein the first sheath and the second sheath have different radial thicknesses.
