Abstract: A support structure 1 for a flexible, heat-exchanging duct of the type that is locatable proximal to cells 4 of a battery pack for thermally managing the battery pack. The support structure 1 is configured to provide support to a duct to prevent the duct kinking when the duct changes direction.

Abstract: A battery pack (1) comprises one or more battery modules (10). A battery module (10) comprises one or more cells (120) and a thermal management arrangement (140) for thermally managing the one or more cells (120). The thermal management arrangement (140) comprises at least one thermal management duct (141), an intake-side fluid delivery arrangement (200c) and an outlet-side fluid delivery arrangement (200d). The inlet-side fluid delivery arrangement (200c) is in fluid communication with the outlet-side fluid delivery arrangement (200d) via the at least one thermal management duct (141). Each fluid delivery arrangement (200) comprises first and second fluid connection arrangements for allowing a thermal management fluid to enter and/or exit the thermal management arrangement (140).

Abstract: A battery pack comprises one or more cells 30, a flexible duct 50/230 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 50/230 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 50/230. A method of manufacturing a battery pack comprises providing one or more cells 30, positioning a flexible duct 50/230 proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 50/230 and the at least one of the one or more cells 30, inserting fluid into the duct 50/230 and at least partially surrounding at least a part of the duct 50/230 with a potting means. The potting means may be expandable foam.

Abstract: A flexible heat transfer material 1 for thermally contacting at least one cell within a battery pack 10, and a method of forming a flexible heat transfer material 1. The flexible heat transfer material 1 is conformable to at least part of the surface shape of at least one cell 20. The flexible heat transfer material 1 comprises a matrix 2 and a filler 3, wherein the thermal conductivity of the filler 3 is greater than the thermal conductivity of the matrix 2.

Abstract: A carrier means 1 for retaining and locating one or more sensing means 2,3 within a battery pack, the battery pack comprising one or more cells and a thermal management duct 10 in thermal contact with at least one cell, the carrier means 1 comprising a sensing means 2,3 for sensing one or more conditions of the battery pack and a connection means 4 for providing a communicative connection to the carrier means 1, wherein the sensing means 2,3 is operably connected to the connection means 4.
