Patent ID: 8765282

Claim:
A battery module, comprising: first, second, and third stacked battery cells, the second battery cell being arranged between the first battery cell and the third battery cell; a first heat transfer layer arranged between the first battery cell and the second battery cell; a second heat transfer layer arranged between the second battery cell and the third battery cell; and a fluid conduit coupled to the first heat transfer layer and the second heat transfer layer, wherein the first, second, and third stacked battery cells, the first heat transfer layer, the second heat transfer layer, and the fluid conduit are arranged such that heat is transferred from the first and second battery cells to the first heat transfer layer, from the second and third battery cells to the second heat transfer layer, and from the first and second heat transfer layers through the fluid conduit to fluid flowing through the fluid conduit, wherein each of the battery cells has first and second faces defined by first and second side edges and first and second end edges, wherein the first heat transfer layer and the second heat transfer layer are coupled together at a first fold around the first side edge of the second battery cell, wherein the fluid conduit includes a first portion that extends between the first fold and the first side edge of the second battery cell, extends parallel to the first side edge of the second battery cell, and extends parallel to the first fold and wherein the fluid conduit forms a first bend that is approximately 180°, and wherein the first bend of fluid conduit is concave with respect to a first direction, the first fold between the first heat transfer layer and the second heat transfer layer is concave with respect to a second direction, the first direction being orthogonal to the second direction.
