1. A battery module, comprising:
a plurality of battery cells each in a cylindrical shape, the plurality of battery cells being arranged in at least two rows; and
a liquid-cooled assembly comprising at least one liquid-cooled unit, wherein each of the at least one liquid-cooled unit comprises a liquid-cooled tube and a cooling fin, the liquid-cooled tube comprising a first tube arranged at an upper end of the cooling fin, a second tube, and a third tube arranged at a lower end of the cooling fin, wherein the second tube connects one end of the first tube with one end of the third tube, wherein the cooling fin is arranged between two adjacent rows and is connected to circumferential side surfaces of battery cells in the two adjacent rows, wherein the first tube has a first opening defined in another end thereof facing away from the second tube, and the third tube has a second opening defined in another end thereof facing away from the second tube, the first opening and the second opening being located on a same side of the at least two rows,
wherein the upper end of the cooling fin is bent to define a first accommodating groove, and the lower end of the cooling fin is bent to define a second accommodating groove, the first tube being accommodated in the first accommodating groove, the third tube being accommodated in the second accommodating groove.
