The present invention provides a battery module reducing a temperature deviation between battery cells without using a lot of members and improving cooling efficiency in spite of the compact structure thereof. The battery module according to the invention comprises: a battery cell stacked body where battery cells are stacked; and a thermoelectric element part in thermal contact with the battery cells positioned on at least one surface of the battery cell staked body. The thermoelectric element part comprises a heat absorbing part and a heat emitting part. The heat absorbing part is in thermal contract with the battery cells. According to the present invention, since the thermoelectric element part is in thermal contact with a plurality of battery cells while corresponding to the battery cells, the entire size of the battery module has no need to be bigger, an additional part is unnecessary, and a manufacturing process is not complicated, compared to a case that multiple refrigerant flow paths have to be secured. In addition, all battery cells are cooled in a batch such that a temperature deviation is not caused. |
