Battery module comprising a cell interconnect for cells comprising terminals positioned on a same side
View Patent ↗A battery module includes: cells, wherein each of the cells including a positive electrode terminal and a negative electrode terminal disposed on one end part, the one end parts being positioned on a same side, and a battery block is constituted by a row of the plurality of cells. The battery module further includes a plate disposed above the one end parts of the cells being arranged, and the plate includes: holes through which the positive electrode terminal and the negative electrode terminal are exposed; and a plurality of conductive members disposed on a surface. The plurality of conductive members extend along the row, two of the plurality of conductive members are disposed in the battery block, and each of the plurality of conductive members includes terminal connecting parts connected through the holes to the terminals of a same pole.
1 . A battery module comprising:
a plurality of cells, each of the plurality of cells including a first electrode terminal and a second electrode terminal disposed on one end part of each of the plurality of cells, the second electrode terminal being located further from a center of the each of the plurality of cells than the first electrode terminal in a radius direction of the each of the plurality of cells, each of the plurality of cells has a cylindrical shape, the plurality of cells being arranged in such a manner that a plurality of one end parts of the plurality of cells are positioned on a same side; and
a plate disposed above the plurality of one end parts of the plurality of cells, the plate including:
holes that are provided in the plate and through each of which the first electrode terminal and the second electrode terminal of each of the plurality of cells are exposed; and
a plurality of conductive members disposed on a surface of the plate opposite to a surface facing the plurality of cells, wherein:
the plurality of conductive members includes a first conductive member and a second conductive member,
the second conductive member includes terminal connecting parts extending into and passing through each of the holes,
each of the holes has a circular portion and a protruding portion radially protruding from the circular portion along a first direction,
a distal end of each of the terminal connecting parts of the second conductive member overlaps the circular portion of each of the holes,
each of the terminal connecting parts of the second conductive member connects to the second terminal in each of the plurality of the cells, and
the first conductive member includes terminal connecting parts, each of which extends along the first direction from an outside of the protruding portion into the protruding portion but does not extend into the circular portion of each of the holes.
2 . The battery module according to claim 1 , wherein:
each of the terminal connecting parts of the first conductive member connects to the first electrode terminal in each of the plurality of cells.
3 . The battery module according to claim 2 , wherein a distal end of each of the terminal connecting parts of the first conductive member connected to a corresponding one of the plurality of cells and the distal end of each of the terminal connecting parts of the second conductive member connected to the corresponding one of the plurality of cells are located within a same corresponding hole of the holes in plan view.
4 . The battery module according to claim 1 , wherein each of the terminal connecting parts of the second conductive member extends along the first direction.
