Abstract:
Disclosed is a battery pack (100), comprising a first battery (10) and a second battery (20). The first battery (10) and the second battery (20) are stacked, and the second battery (20) is closer to the center of the battery pack (100) than the first battery (10) in the stacking direction. The first battery (10) includes a first heat conduction member (12) and a first battery cell (14); the second battery includes a second heat conduction member (22) and a second battery cell (24). The heat conduction efficiency of the second heat conduction member (22) is not lower than that of the first heat conduction member (12). The battery pack (100) can achieve temperature uniformity while maintaining a low overall temperature of the battery pack (100).
