Abstract
Official abstract text for this publication.
Provided is a battery pack including: a first battery group in which a plurality of storage batteries having a battery can side surface and a battery can bottom surface linked to the battery can side surface are laminated so that the battery can side surfaces face each other; a second battery group in which a plurality of storage batteries having a battery can side surface and a battery can bottom surface linked to the battery can side surface are laminated so that the battery can side surfaces are face each other; and a case housing the first battery group and the second battery group, wherein the facing surfaces of the first battery group and the second battery group are directly or indirectly thermally connected to each other.
First claim
Opening claim text (preview).
1 . A battery pack comprising: a first battery group and a second battery group in each of which a plurality of storage batteries are laminated, with each storage battery formed in a cuboid composed of wide surfaces and narrow surfaces, so that the wide surfaces are placed to face each other; a bus bar for connecting the first battery group and the second battery group together; and a first external terminal for connecting the first battery group to an electronic circuit and a second external terminal for connecting the second battery group to the electronic circuit, wherein the first battery group and the second battery group are disposed side by side inside a case housing so that the narrow surfaces of the first battery group and the narrow surfaces of the second battery group face each other; and wherein the first external terminal is disposed on the narrow surfaces of the first battery group and the second external terminal is disposed on the narrow surfaces of the second battery group so that the first external terminal and the second external terminal face each other. 2 . The battery pack according to claim 1 , wherein a storage battery on a top surface of each of the first battery group and the second battery group is provided with the first external terminal and the second external terminal. 3 . The battery pack according to claim 1 , wherein the first external terminal and the second external terminal are provided around a center of the battery pack. 4 . The battery pack according to claim 1 , wherein additional narrow surfaces of each of the first battery group and the second battery group, which are not the narrow surfaces of the first battery group and the second battery group placed to face each other, are provided with the first external terminal and the second external terminal. 5 . The battery pack according to claim 2 , wherein the first external terminal and the second external terminal are provided around a center of the battery pack. 6 . The battery pack according to claim 2 , wherein additional narrow surfaces of each of the first battery group and the second battery group, which are not the narrow surfaces of the first battery group and the second battery group placed to face each other, are provided with the first external terminal and the second external terminal. 7 . The battery pack according to claim 3 , wherein additional narrow surfaces of each of the first battery group and the second battery group, which are not the narrow surfaces of the first battery group and the second battery group placed to face each other, are provided with the first external terminal and the second external terminal.
