description The invention discloses a control method of a battery pack, a battery management system, the battery pack and electric equipment. The battery pack comprises at least one first unit and at least one battery cell, the first units and the battery cells are connected in a one-to-one correspondence mode, and the method comprises the steps that the temperature of each battery cell in the at least one battery cell is obtained; if the temperature of a first battery cell in the at least one battery cell is greater than or equal to a first temperature threshold value, determining at least one bypass battery cell in physical contact with the first battery cell, and controlling each bypass battery cell to discharge to the corresponding first unit so as to reduce the voltage of each bypass battery cell; and/or acquiring the voltage of each battery cell in the at least one battery cell; and if the voltage of a second battery cell in the at least one battery cell is greater than or equal to the first voltage threshold value
