Assembled battery
View Patent ↗The purpose of the present invention is to provide an assembled battery including a battery holder capable of holding single battery cells while automatically aligning the cells during assembly. In the assembled battery ( 100 ) according to the present invention, a plurality of single battery cells ( 101 ) arranged in a row and battery holders ( 144 ) disposed between the plurality of single battery cells ( 101 ) are held in a state of being mutually pressed in an arranged direction. The battery holders ( 144 ) include a positioning means ( 144 f, 144 g ) that positions the single battery cells ( 101 ) by biasing the single battery cells ( 101 ), while being pressed in the arranged direction, in a direction intersecting the arranged direction.
1. An assembled battery comprising:
a plurality of single battery cells arranged in a row; and
a battery holder disposed between the plurality of single battery cells, the single battery cells and the battery holder being held in a state of being mutually pressed in an arranged direction,
wherein the battery holder includes a positioning means that positions the single battery cells by biasing the single battery cells, while being pressed in the arranged direction, in a direction intersecting the arranged direction,
wherein the single battery cells include a flat and square battery can, and
wherein the positioning means includes an inclined face abutted against a corner portion disposed on a side in the arranged direction of the battery can, the inclined face being inclined in a direction intersecting the arranged direction.
2. The assembled battery according to claim 1 , wherein the positioning means positions the single batteries in a cell height direction by biasing the battery can upward in the cell height direction.
3. The assembled battery according to claim 1 , wherein the positioning means positions the single battery cells in a cell width direction by biasing the battery can from one side to another side in the cell width direction.
4. The assembled battery according to claim 1 , wherein the inclined face is abutted against the corner portion positioned at a lower side in the cell height direction and on the side in the arranged direction of the battery can, and is inclined upward from under the battery holder.
5. The assembled battery according to claim 1 , wherein the inclined face is abutted against the corner portion positioned at one side in the cell width direction and on the side in the arranged direction of the battery can, and is inclined from one side to another side in the cell width direction of the battery can.
