Abstract
Official abstract text for this publication.
There are provided a plate for a buttery stack and battery stack including: a plate-shaped housing having a fitting groove provided in a recessed shape in a first plate side surface of the plate for the battery stack along a longitudinal direction thereof; a plurality of bottomed first recessed holes formed side by side in a direction orthogonal to a plate thickness direction of the plate for the battery stack, and extending from a second plate side surface opposite to the first plate side surface; and a plurality of second recessed holes formed side by side in the direction orthogonal to the plate thickness direction, and extending from a bottom portion of the fitting groove to be positioned between the two adjacent first recessed holes.
First claim
Opening claim text (preview).
What is claimed is: 1 . A plate for a battery stack configured to be sandwiched between a plurality of power storage modules, comprising: a plate-shaped housing having a fitting groove provided in a recessed shape in a first plate side surface of the plate for the battery stack along a longitudinal direction thereof, the fitting groove being a groove configured to fit with a side edge portion of a conductive plate disposed between the plurality of stacked power storage modules; a plurality of bottomed first recessed holes formed side by side in a direction orthogonal to a plate thickness direction of the plate for the battery stack, and extending from a second plate side surface opposite to the first plate side surface; and a plurality of second recessed holes formed side by side in the direction orthogonal to the plate thickness direction, and extending from a bottom portion of the fitting groove to be positioned between the two adjacent first recessed holes. 2 . The plate for the battery stack according to claim 1 , further comprising: a recess formed to penetrate in the plate thickness direction, and extending from a third plate side surface intersecting with the first plate side surface; a plurality of bottomed third recessed holes formed side by side in the direction orthogonal to the plate thickness direction, and extending from the second plate side surface in a corresponding position to the recess; and a plurality of bottomed fourth recessed holes formed side by side in the direction orthogonal to the plate thickness direction, and extending from the bottom portion of the fitting groove in the corresponding position to the recess, wherein an opening width in a direction in which the fourth recessed holes are arranged is narrower than an opening width in a direction in which the third recessed holes are arranged, and a hole depth of the fourth recessed holes is shallower than a hole depth of the third recessed holes. 3 . The plate for the battery stack according to claim 2 , further comprising: a battery temperature sensor accommodated in the recess; and an electric wire having one terminal connected to the battery temperature sensor. 4 . A battery stack comprising: the plate for the battery stack according to claim 1 .
