Title
(EN) A BATTERY PACK AND A METHOD OF MANUFACTURING A BATTERY PACK
(FR) BLOC-BATTERIE ET PROCÉDÉ DE FABRICATION D'UN BLOC-BATTERIE
Abstract
(EN)
A battery pack comprises one or more cells 30, a flexible duct 50 positioned proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 50 and at least one of the one or more cells 30 and a potting means which at least partially surrounds at least a part of the duct 50. A method of manufacturing a battery pack comprises providing one or more cells 30, positioning a flexible duct 50 proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 0 and the at least one of the one or more cells 30, inserting fluid into the duct 50 and at least partially surrounding at least a part of the duct 50 with a potting means. The potting means may be expandable foam.

L'invention concerne un bloc-batterie comprenant une ou plusieurs cellules (30), un conduit flexible (50) positionné de manière proximale par rapport à la surface de la ou des cellules (30) de telle sorte que de la chaleur peut être échangée entre le conduit (50) et au moins l'une de la ou des cellules (30) et un moyen d'enrobage qui entoure au moins partiellement au moins une partie du conduit (50). Un procédé de fabrication d'un bloc-batterie comprend la fourniture d'une ou plusieurs cellules (30), le positionnement d'un conduit flexible (50) de manière proximale par rapport à la surface d'au moins l'une de la ou des cellules (30) de telle sorte que de la chaleur puisse être échangée entre le conduit (50) et l'au moins l'une de la ou les cellules (30), l'introduction d'un fluide dans le conduit (50) et l'enrobage au moins partiel d'au moins une partie du conduit (50) avec un moyen d'enrobage. Le moyen d'enrobage peut être une mousse expansible.
