電池パック
Document Type and Number:
Japanese Patent JP5510044
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a battery pack having compatibility with both improved cooling performance between battery cells and secured restraint strength given to the battery cells.SOLUTION: A battery pack 1 includes: a plurality of plate-shaped protrusions 241, each disposed on each side face of battery cells 2 orthogonal to a lamination direction X, in such a manner as to extend to a cooling fluid flow direction F, and disposed to be arrayed in a direction Y orthogonal to the cooling fluid flow direction F, so as to form a path between mutually adjacent battery cells 2; and a plurality of enlarged protrusions 23 disposed halfway the plate-shaped protrusions 241 extending to the cooling fluid flow direction F, so as to receive an action force from the mutually adjacent battery cells 2 by contacting to the mutually adjacent battery cells 2. In the direction Y of the arrayed plurality of plate-shaped protrusions, each enlarged protrusion 23 has an external dimension larger than the plate thickness dimension of each plate-shaped protrusion 241.
