Abstract

An electrical power supply device for a motor vehicle, which includes a tray made of a heat-conducting material, in which there is positioned at least one ultra-high capacity energy storage unit liable to emit heat, the tray including at least one housing to accommodate at least one electrical energy storage unit with the presence of a heat-conducting layer made of a heat conducting adhesive or a heat-conducting resin interposed without clearance between the storage unit and the interior face of the wall of the associated housing so as to conduct the heat emitted by the unit.

Claims

1. An electrical supply device (10) for a motor vehicle, which comprises a tray (32, 34, 134) in which there is provided at least one ultra high-capacity electrical energy storage unit (20) which can emit heat, the tray (32, 34, 134, 334) comprising at least one receptacle (44, 144, 234) for receipt of at least one electrical energy storage unit (20), wherein firstly the tray (32, 34, 134) is made of a heat-conducting material, such as to conduct the heat emitted by the storage unit from the inner surface (46) to the outer surface (51, 52, 151) of the wall (43) of the receptacle (44, 144, 234), and secondly the tray is divided up into a plurality of receptacles (44, 44′

, 144) which are each designed to accommodate at least one storage unit (20), the wall (43) of each receptacle being made of the heat-conducting material, characterised in that a heat conduction layer (54) which is made of a heat-conducting glue or a heat-conducting resin is interposed without play between the storage unit (20) and the inner surface (46) of the wall (43) of the associated receptacle (44, 144, 234), such as to conduct the heat emitted by the storage unit (20) directly to the inner surface (46) of the wall (43) of the receptacle (44, 144, 234).

2. A supply device (10) according to claim 1, characterised in that the heat-conducting resin and the said heat-conducting glue are electrically insulating.

3. A supply device (10) according to preceding claims claim 1, characterised in that the heat-conducting resin is injected between the storage unit (20) and the wall (43) of the receptacle (44).

4. A supply device (10) according to claim 3, characterised in that the heat-conducting resin hardens after being injected, such as to wedge the storage unit (20) in the receptacle (44).

5. A supply device (10) according to claim 4, characterised in that the hardened heat-conducting resin is resiliently deformable.

6. A supply device (10) according to claim 4, characterised in that the hardened heat-conducting resin is adhesive.

7. A supply device (10) according to claim 1, characterised in that the receptacles (44144, 234) are dividing walls.

8. A supply device (10) according to claim 1, characterised in that each receptacle (44) comprises an individual wall (43), such that the outer surfaces (51) of the receptacles (44) form the outer surface (51) of the tray (34).

9. A supply device (10) according to claim 1, characterised in that the outer surface (51, 151) of the receptacle (44, 144) is undulating.

10. A supply device according to claim 1, characterised in that the receptacle is blind (44) and the electrical energy storage units (20) are wedged in the base (48) of the blind receptacle (44), by a layer of heat-conducting glue (56).

11. A supply device (10) according to claim 1, characterised in that the receptacle (44, 144, 234) is a receptacle to receive a pair of electrical energy storage units which are arranged in an adjacent manner in the common receipt receptacle (44, 144, 234) which has an oblong form.

12. A supply device (10) according to claim 11, characterised in that the common receptacle is globally in the shape of an “

8”

.

13. A supply device (10) according to claim 11, characterised in that each receptacle (144) is globally in the shape of a half “

8”

.

14. A supply device (10) according to claim 1, characterised in that the tray (44, 134) is made of metal.

15. A supply device (10) according to claim 1, characterised in that the layer of heat-conducting resin is 2 mm or less.
