Abstract
Disclosed are a submodule and a battery module having the same, the submodule being comprising a three or more odd numbers of cells, and including: a cell unit divided into one single cell and at least one double cell; a first cooling fin provided at a side of the single cell and bent in a thickness direction of the single cell; and a second cooling fin provided between two cells composing the double cell and bent in thickness directions of the two cells. The single cell is cooled by the first cooling fin in surface contact with an exposed surface of the single cell, and the double cell is cooled by the second cooling fin in surface contact with stacked surfaces of the two cells, whereby all cells can be equally cooled, and energy density of the submodule can be increased by using a minimum number of members.
