WIPO Patent Application WO/2018/225294
Kind Code:
A1
Abstract:
The purpose of the present invention is to efficiently suppress temperature rise in a secondary battery module. A battery module is provided with: a battery group in which secondary batteries having a pair of first side surfaces, a pair of second side surfaces, and a bottom surface connected to the first and second side surfaces are stacked such that the first side surfaces oppose each other; a lashing member which is connected to the second side surfaces of the secondary batteries configuring the battery group, and which presses onto the second side surfaces; and a housing in which the battery group and the lashing member are accommodated, and which is directly or indirectly closely attached to the bottom surface of the secondary batteries. The lashing member includes a pressing portion pressing onto the bottom surface of the secondary batteries configuring the battery group.
