Abstract
Official abstract text for this publication.
A battery frame includes a pair of flat spring plates, a pair of pressing plates, and connecting members connecting the pair of flat spring plates. Each of the flat spring plates includes first regions and a second region. The second region is located inward of the first regions in the stacking direction of a battery cell stack. The connecting members are attached to the flat spring plates via the first regions, and the pressing plates are attached to the flat spring plates via the second regions.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A battery frame that holds a battery cell stack comprising a plurality of battery cells stacked in a thickness direction thereof, the battery frame comprising: a pair of flat spring plates; a pair of pressing plates; and a connecting member configured to connect the pair of flat spring plates, wherein the pair of pressing plates are provided between the pair of flat spring plates, the battery cell stack is provided between the pair of pressing plates, each of the flat spring plates includes a first region and a second region, the second region of each of the flat spring plates is located inward of the first region of each of the flat spring plates in a stacking direction of the battery cell stack, the connecting member is attached to the first region of each of the flat spring plates, each of the pressing plates is attached to the second region of a corresponding one of the flat spring plates, each of the flat spring plates includes four arm portions extending from a central portion of each of the flat spring plates, each of the pressing plates is disposed inward of the connecting member, and each of the pressing plates is attached to the central portion of each of the flat spring plates with a fastening member. 2 . The battery frame according to claim 1 , wherein the first region of each of the flat spring plates and each of the pressing plates overlap each other in a direction orthogonal to the stacking direction. 3 . The battery frame according to claim 1 , wherein adjustment bolts are attached to the connecting member, and the adjustment bolts adjust a pressure applied from the pressing plates to the battery cell stack in the stacking direction. 4 . The battery frame according to claim 1 , wherein the connecting member is a shaft extending in the stacking direction.
