Abstract: The present disclosure provides a battery pack, including: a battery box (1), a plurality of battery modules (2), a cooling plate (3), and a buffering member (4). Each battery module (2) includes a plurality of battery cells (21) and a plurality of busbars (22). Each battery cell (21) includes an electrode assembly (211) and a battery housing (212). The battery cells (21) are laid flat. When the electrode assembly (211) is of a wound structure and is flat, and outer surfaces of the electrode assembly (211) include two flat surfaces (2110). The two flat surfaces (2110) are opposite to each other in a vertical direction. Alternatively, when the electrode assembly (211) is of a laminated structure, a first electrode plate (2111), a separator (2113), and a second electrode plate (2112) are stacked in a vertical direction. Therefore, the electrode assembly (211) of the battery cells (21) applies a greatest expansion force in the vertical direction during charge and discharge. The cooling plate (3) is disposed at a side of the battery module (2) in the vertical direction, and the buffering member (4) is disposed between the cooling plate (3) and the battery box (1). Therefore, the greatest expansion force applied by the battery cells (21) on the buffering member (4) enables the buffering member (4) to fit closely with both the cooling plate (3) and the battery box (1) concurrently, thereby increasing a heat dissipation area to improve heat dissipation effects of the cooling plate (3).
