Terminal-attached plate, plate assembly, and battery module

A plate assembly for use in a battery module, the battery module comprising:

• a single-cell stack comprising thin batteries stacked in a thickness direction, each battery of the single-cell stack comprising thin batteries comprises:
• a thin-plate-shaped battery body comprising an electric power generation element sealed with an exterior package, and
• tabs connected to electrodes of the electric power generation element and drawn to the outside from end portions of the exterior package;
• and
• a plate assembly connected to an end portion of the single-cell stack, the plate assembly comprising a plurality of stacked plates, each plate of the plurality of stacked plates comprising:
• a joining portion, with which the plate is arranged to be joined to an end portion of the thin battery;
• a plate supporting portion arranged to support another plate of the plurality of stacked plates that is stacked on the plate;
• a terminal comprising:
• a connecting portion, with which the terminal is arranged to be connected to a tab of the thin battery;
• and
• a contact portion, with which the terminal is arranged to be connected to a connector;
• and
• a hood member arranged to protect the contact portion of the terminal,
• wherein:
• the hood member is disposed at a position that is offset to an end portion side of the plate from a center in a longitudinal direction of the plate,
• at least a portion of the hood member overlaps a hood member of another plate in a direction orthogonal to a direction of stacking of the plurality of stacked plates in the plate assembly, and
• the plurality of stacked plates are stacked while the another plate that is turned back relative to the plate in a width direction of the plate, is stacked on the plate.
