Abstract
Official abstract text for this publication.
Provided is an assembled battery which is downsized and in which a fastening force between a busbar and an external terminal cable at a fixing part is improved. Provided is an assembled battery including: a group of cells in which a plurality of cells, each having electrode terminals, is stacked; plate-shaped members arranged at ends of the group of cells; and cell holders arranged between the plate-shaped members and the group of cells, in which each of the cell holders is provided with a terminal fixing part of the assembled battery, and each of the plate-shaped members has a fitting part to be fitted to the terminal fixing part.
First claim
Opening claim text (preview).
The invention claimed is: 1. An assembled battery comprising: a group of cells in which a plurality of cells, each having electrode terminals, is stacked; plate-shaped members arranged at ends of the group of cells; and cell holders arranged between the plate-shaped members and the group of cells, wherein each of the cell holders is provided with a terminal fixing part of the assembled battery, and each of the plate-shaped members has a recess on a top surface for inserting the terminal fixing part, wherein one of the cell holders is in direct contact with one of the plate-shaped members, and wherein the recess has a same shape as the terminal fixing part. 2. The assembled battery according to claim 1 , wherein the plate-shaped members are end plates. 3. The assembled battery according to claim 1 , wherein the plate-shaped members are a part of a housing. 4. The assembled battery according to claim 2 , wherein the terminal fixing part has a rectangular shape. 5. The assembled battery according to claim 2 , wherein a head of a bolt or a nut is inserted in the terminal fixing part. 6. The assembled battery according to claim 2 , wherein the terminal fixing part is arranged on the cell holder at a position facing an external terminal of one of the cells. 7. The assembled battery according to claim 2 , wherein the terminal fixing part is arranged at a central portion of the cell holder.
