Japanese Patent JP6488889
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device module capable of preventing an excessive constraint load from being added to a predetermined region of a power storage device, while securing a heat dissipation property of the power storage device.SOLUTION: A battery module comprises: an array body that is formed by arraying a plurality of batteries that are held by a cell holder 5; and an end plate that adds a constraint load to the array body in an array direction of batteries. The cell holder 5 includes: a back plate 51; and a plurality of first ribs 52 and a plurality of second ribs 53 that are provided protrusively on one surface 51a of the back plate 51, form a flow passage S of cooling air A and support a loads of batteries during expansion. The first ribs 52 are arrayed along an edge of the back plate 51. The second ribs 53 are arrayed inside of the edge of the back plate 51 in such a manner that the second ribs 53 are offset in a Z direction of the one surface 51a of the back plate 51 relatively to the first ribs 52. A cross-sectional area of the second rib 53 is smaller than a cross-sectional area of the first rib 52.SELECTED DRAWING: Figure 2
