Abstract

The present application relates to a battery module including a first-type battery cell and a second-type battery cell at least connected in series, where the first-type battery cell and the second-type battery cell are battery cells of different chemical systems, the first-type battery cell includes N first battery cell(s), and the second-type battery cell includes M second battery cell(s), where N and M are positive integers; and when a battery state of health (SOH) of a first battery cell is the same as an SOH of a second battery cell, and a state of charge (SOC) of the first battery cell is the same as an SOC of the second battery cell, a ratio of a total charge capacity of a first negative electrode sheet of the first battery cell to a total charge capacity of a second negative electrode sheet of the second battery cell is 0.8 to 1.2.
