Abstract
A battery module for enhancing cooling performance, and a battery pack including the same may include a battery cell stack, in which a plurality of battery cells are stacked, a U-shaped frame accommodating the battery cell stack and having an opened upper portion, an upper plate covering the battery cell stack on the opened upper portion of the U-shaped frame, and a thermally conductive resin layer formed between the battery cell stack and a bottom surface of the U-shaped frame, and the upper plate may include a recessed portion formed to be recessed in a direction in which the battery cell stack is located, and a battery pack including the same.
Claims9
A battery module comprising:
- a battery cell stack, in which a plurality of battery cells each extending in a longitudinal direction are stacked adjacent to one another in a lateral stacking direction perpendicular to the longitudinal direction;
- a U-shaped frame accommodating the battery cell stack and having an opened upper portion;
- an upper plate covering the battery cell stack on the opened upper portion of the U-shaped frame;
- and
- a thermally conductive resin layer formed between the battery cell stack and a bottom surface of the U-shaped frame,
- wherein the upper plate comprises a recessed portion formed to be recessed towards the battery cell stack in a vertical direction in which the battery cell stack is located, the recessed portion extending in the lateral stacking direction across all of the battery cells,
- wherein the recessed portion contacts a highest point of each of the battery cells in the vertical direction and presses the battery cells in the vertical direction that is perpendicular to the lateral stacking direction and the longitudinal direction.
