Abstract: Provided are a battery pack and a power consuming device. The battery pack includes a battery pack case and a plurality of battery cells accommodated in the battery pack case. An inner space of the battery pack case may be divided into a first region located at the center and a second region enclosing the first region. The plurality of battery cells include: at least one first battery cell disposed in the first region; and at least one second battery cell disposed in the second region. An internal resistance of the first battery cell and an internal resistance of the second battery cell increase with the decrease of a temperature.
