Patent ID: 8582294

Claim:
An electrical supply device ( 10 ) for a motor vehicle, comprising: a tray ( 32 , 34 , 134 ) housing a plurality of ultra high-capacity electrical energy storage units ( 20 ) each capable of emitting a heat; the tray ( 32 , 34 , 134 ) comprising a plurality of receptacles ( 44 , 144 , 234 ) each provided for receiving at least one of the electrical energy storage units ( 20 ), each of the receptacles including a wall ( 43 ) having an inner surface ( 46 ) and an outer surface ( 51 , 52 , 151 ); the tray ( 32 , 34 , 134 ) being 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 each of the receptacles ( 44 , 144 , 234 ); the tray being divided by the wall into the plurality of the receptacles ( 44 , 44 ′, 144 ) each designed to accommodate the at least one storage unit ( 20 ), the wall ( 43 ) of each of the receptacles being made of the heat-conducting material; and a heat conduction layer ( 54 ) made of a heat-conducting glue or a heat-conducting resin and 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 ).
