Abstract
A battery pack may include a first battery cell type and a second battery cell type, wherein the first battery cell type may include n first battery cells, and the second battery cell type may include m second battery cells, with n and m being each independently selected from an integer of 1 or more, wherein the second battery cell may have a discharge power at −20° C. greater than that of the first battery cell, the difference in discharge power at −20° C. between the second battery cells and the first battery cells being ≥10 W; the percentage by number of the first battery cells in the battery cells comprised in area A may be 20% to 100%, and the percentage by number of the second battery cells in the battery cells comprised in the area B may be 5% to 100%.
