US 2013/0252045 A1 · BATTERY MODULE

Abstract

A battery module includes a first unit cell arranged parallel to a second unit cell and a spacer arranged between the first and second unit cell. Each of the first and second unit cells includes a first electrode terminal and a second electrode terminal having a polarity opposite to that of the first electrode terminal. The spacer includes a main body and a first wall portion extending upward from the main body, and the first wall portion is disposed at and between the first electrode terminal of the first unit cell and the second electrode terminal of the second unit cell. The first electrode terminal of the first unit cell is juxtaposed to the second electrode terminal of the second unit cell.

A battery module comprising:

a first unit cell arranged parallel to a second unit cell, each of the first and second unit cells comprising a first electrode terminal and a second electrode terminal having a polarity opposite to that of the first electrode terminal;
and
a spacer arranged between the first and second unit cells,
wherein the spacer comprises a main body and a first wall portion extending upward from the main body, and the first wall portion is disposed at and between the first electrode terminal of the first unit cell and the second electrode terminal of the second unit cell, the first wall portion having a height greater than a height of the first electrode terminal of the first unit cell, the first electrode terminal of the first unit cell being juxtaposed to the second electrode terminal of the second unit cell.

1 more element

A battery module comprising:

a plurality of unit cells alternately arranged such that locations of first and second electrode terminals of one of the unit cells are juxtaposed to second and first electrode terminals of a neighboring one of the unit cells in a thicknesswise direction of the unit cells;
a plurality of spacers arranged between the plurality of unit cells;
and
a plurality of bus bars electrically connecting the plurality of unit cells,
wherein each of the plurality of spacers comprises a main body and a first wall portion extending upward from the main body, the first wall portion being disposed between two neighboring bus bars of the plurality of bus bars and having a height greater than a height of the first electrode terminal of one of the unit cells, and
wherein the plurality of spacers are alternately arranged to form independent bus bar space.
